Default 2008 Acura RL - Interior

Torrance, Calif. - Sep 11 —


The RL interior is designed to integrate richly elegant luxury, efficient
design, and to create an environment in tune with the car's clearly defined
sporting character. At the same time, the interior makes the most advanced technology
ever built into an Acura intuitive and easy to operate. Careful integration
of the many advanced systems ensures that they add to the driver's comfort,
control and understanding of the driving situation—all without detracting
from it. The finest interior materials and exacting attention to detail highlight
the quiet interior.

The RL features a broad list of standard equipment, including the Acura/Bose
DVD-Audio system that delivers surround sound in all seating positions, XM®
Satellite Radio, an MP3 auxiliary jack and a passenger seatbelt reminder.

Acura Bluetooth® HandsFreeLink® wireless phone connectivity allows
the driver to dial a Bluetooth®-enabled mobile phone by voice and satellite-based
AcuraLink™ allows communication between the RL owner and Acura, thus there
has never been a more "connected" vehicle than the RL. The RL is also the first
Acura equipped with the Keyless Access System, which allows owners to lock and
unlock doors, open the trunk, and start the car without having the keyless remote
in the hand.

For 2008, models equipped with the optional RL Technology Package plus CMBS™
and PAX® Tires feature the innovative Adaptive Cruise Control (ACC) system,
which can maintain a consistent following distance interval between the RL and
the vehicle directly in front of it.

The quality of materials, fit and finish have received close attention to
reflect the spirit of the RL. The large, bright navigation system display is
positioned up high, in the center of the instrument panel within easy line of
sight of the driver and passenger. Below the navigation system screen, the satin
metal finish of the climate, audio and navigation controls has a clean, technical
look. And an available upgraded wood interior sweeps across the instrument panel.


Acura interior design has always made intuitive functionality a priority. All
important systems and controls are within easy reach of the driver. The systems
used most frequently—audio, cruise control, Bluetooth® HandsFreeLink®
Satellite-Linked Navigation System and Multi-Information Display—have
controls positioned on the steering wheel. The main instrumentation is an easy-to-read
analog design, supplemented with digital and graphic displays. Even though the
RL gives its driver access to many electronic features and conveniences, the
interface is simple and welcoming. Sight lines are clear with important items
placed within easy view.

Typical of Acura interior design, the soft-touch switchgear of the RL is engineered
to deliver a quality feel and positive action. Helpful features make driving
easier, like power rearview mirrors that can be set to automatically tilt-down
when reverse is engaged to make parking simpler. There is also a bottom-hinged
throttle pedal to provide a linear feel and natural motion. A large dead pedal
in the driver-side foot well provides extra support for the driver's left food
during aggressive driving.


The leather wrapped steering wheel incorporates the most commonly used controls,
allowing the driver to keep their hands on the wheel while using them. Audio
system controls are on the upper left spoke, while cruise control buttons are
on the right upper spoke. The lower left spoke is reserved for navigation system
controls, including a push-to-talk button to activate the voice recognition
system that provides voice control of the navigation system, as well as many
climate control and audio system features.

Also on the left, between the spokes, are controls for Bluetooth® HandsFreeLink®.
On the right, between the spokes, are controls for the MID. Tucked out of view,
but within fingertip reach, is a pair of paddles that upshift and downshift
the Sequential SportShift 5-speed automatic transmission when it is in manual

On models equipped with the optional RL with Technology Package plus CMBS™
and PAX® Tires, control buttons for the Adaptive Cruise Control and Collision
Mitigation Braking System™ are located on the upper and lower right-hand


Most of the commonly used electronic functions have dedicated controls positioned
on the instrument panel or on the steering wheel. Voice control of navigation,
climate control, audio and communications functions available, while an Interface
Dial positioned just ahead of the front center console-mounted shift lever provides
another avenue of control. The Interface Dial is rotated and rocked like a joystick
to select function menus displayed on the navigation screen. A push of the controller
selects the highlighted item. Functions controlled by the Interface Dial include:

  • Audio

  • Navigation

  • Climate Control System

  • AcuraLink™ satellite communications system


Given the performance capabilities and luxury mission of the RL, its passenger
seating required extensive engineering development. In particular, the front
seats had to blend long-trip comfort with secure lateral support given the cornering
potential afforded by the advanced SH-AWD™ system. As a result, the front
seats are taller and wider than in the past, which also allows them to accommodate
a wide range of body types. The RL seat cushions are constructed of a special
urethane with high damping coupled with a new wider "S" spring design for better
support of the urethane padding. These features work together to reduce the
amount of road and engine vibration transmitted to the passenger.

The driver's seat is 8-way power adjustable and includes a power-adjustable
lumbar support mechanism. The smooth shape of the articulated lumbar mechanism
matches the human spinal curvature to provide solid support for the torso and
pelvis. All driver's seat power adjustments (except power adjustable lumbar
support) are included in the Keyless Access System, which stores a pair of user
profiles, one for each of the two fobs that come standard with the RL.

The front passenger seat is 4-way power adjustable with power adjustable lumbar
support. In the rear seat area, the outer seating positions are carefully engineered—complete
with side bolsters—to simultaneously combine luxurious comfort on long
trips with solid lateral support.

In front, 4-way headrests are adjustable for height and tilt. In back, the
three headrests have a remote retractable feature that allows the driver to
lower them with a touch of an overhead button for better rearward visibility
when there are no rear-seat passengers. When carrying rear passengers, the headrests
can be raised manually for use.


A highly functional instrument panel gives the RL driver instant access to
critical information. It also provides important vehicle information via an
LCD Multi-Information Display (MID) positioned in the lower speedometer face.
The MID shows many items including vehicle mileage and trip mileage. Controls
positioned at the 4 o'clock position of the steering wheel hub allow the driver
to cycle the display through multiple screens of information from sources including
CMBS™ and ACC on models equipped with the available RL with Technology
Package plus CMBS™ and PAX® Tires.

Trip computer functions include average and instantaneous fuel economy, average
speed, fuel range, and elapsed time. The system also can display outside air
temperature, engine oil life as a percentage, SH-AWD™ torque distribution,
and tire pressures. The Maintenance Minder System alerts the RL driver of upcoming
maintenance needs via the MID; should a fault occur with the vehicle, warning
information also appears (see Engine section for more information).


The theme of efficient driver control and easy to read components carries
on after dark in the RL. The analog instruments are LED backlit, with high-contrast
markings and a subdued blue accent hue. The progressive self-illuminating gauge
package gives the car a welcoming feel. When the door is first opened, the instrument
lighting comes to life and then brightens progressively to 100-percent illumination
when the ignition is switched on. The illuminated instrument needles and enunciator
lights then come alive, indicating that the car is ready to go. At the end of
the drive, the instrument lighting dims progressively.

All the interior switches are illuminated to make them easy to locate at night,
including switches on all four doors and the steering wheel. In addition to
front and rear overhead interior lights and map lights, the RL also has a complement
of low-level interior ambient cabin lighting. Blue front and rear low-level
ambient lighting in the ceiling illuminates the front center console and the
rear flip-down armrest. The front foot wells also have low-level ambient lighting
that brightens substantially when the doors are opened.

Front and rear interior door handle areas are also illuminated to make them
easy to find, and the front door storage compartments, glove compartment and
the front armrest compartment are all internally illuminated. All four doors
have courtesy lights that illuminate when the doors are open. The RL interior
lights feature "theater dimming," which can be set by the driver to
any of several dimming rates via the Multi-Information Display. The trunk has
interior lighting, plus the trunk lid has lighting that illuminates the bumper
and sill area when the lid is opened.


The RL interior offers plenty of storage and convenience features for driver
and passengers. The front center armrest has a unique dual lid, which allows
the padded armrest to be used on one side, while the lid on the other side is
opened. The upper portion of the armrest can be swiveled up to allow access
to a large lower storage compartment. A front double beverage holder has an
adjustable bottom tray that allows it to accommodate a wide range of container

Inside the glove compartment is a separate document box that allows the RL
User Manual and important registration and insurance papers to be stored safely.
This arrangement also frees up storage space in the main glove box compartment.

In the rear seating area, the rear folding armrest has a padded top. A pullout
dual beverage holder is built into the rear armrest.


The RL has a generously sized 13.1 cubic-foot trunk that is fully finished,
with all wiring concealed and the rear parcel shelf speakers and navigation
unit fully protected. The acoustic properties of the trunk and the three rear
deck speakers were specially engineered together to create the best possible
sound performance from the Acura/Bose DVD-Audio system. To allow room for longer
items, a locking trunk pass-through is provided. A standard cargo net and a
network of anchor points help keep cargo securely in position. The spare tire
is located under a folding cover within the trunk floor.

For a cleaner appearance and to avoid damage to luggage, the lightweight aluminum
trunk lid is supported by fully concealed hinge mechanisms. The trunk can be
opened via a remote release mounted on the driver's door panel, by pulling the
exterior release on the lid when carrying the Keyless Access fob, or with a
manual release accessible through the locking trunk pass-through. There is also
an emergency trunk opener inside, near the trunk latch. For security, the trunk
main switch is located in the glove box, which can be locked to prevent access
by valets. A valet key is provided that will allow a parking attendant to operate
the ignition, but will not to open the glove box, trunk, or locking trunk pass-through
if it is locked by the driver.


The RL has a GPS-based, solar-sensing, dual-zone, dual-mode automatic climate
control system that lets the driver and front passenger set temperature modes
to their individual liking. A pair of large adjustable vents in the rear of
the center console keeps the rear seat area comfortable. Large, simple to use
system controls are positioned within easy reach, just below the center instrument
panel vents. The system can also be controlled by voice, and some seldom-needed
custom settings can also be accessed through the Interface Dial. The climate
control system's control logic is designed to provide smooth operation with
subtle changes in airflow.

With its position-sensing ability, the GPS navigation system contributes to
overall passenger comfort with 3D solar sensing. Based on its continuously updated
vehicle position information, the navigation system determines the position
of the sun relative to the driver and passenger. Combining this information
with input from a solar sensor located on top of the instrument panel, the climate
control system automatically adjusts the temperature and airflow from side to
side as needed to compensate for asymmetrical solar heating.

System operation can be customized to suit the preferences of the driver and
front seat passenger. Using the navigation screen and the Interface Dial, the
temperature of the air flowing through the upper vents can be fine-tuned relative
to that of the air flowing from the footwell vents.


For greater passenger comfort on sunny days, the RL has a power operated rear-window
sunshade, plus manually operated sunshades for each rear side window.


The 2008 RL features Active Noise Cancellation™ (ANC™), which
is designed to dramatically reduce low frequency noise in the interior. The
system operates whenever the car is running, regardless of whether the Acura/Bose®
audio system is on or off. There are two microphones in the headliner, one just
behind the front overhead console, and another just ahead of the overhead rear
light module. The microphones capture low-end drivetrain frequencies entering
the cabin, and send a signal to the Active Noise Cancellation™ unit. The
control unit then creates a precisely timed reverse phase audio signal that
is sent to an amplifier, which powers the door speakers and the subwoofer positioned
on the rear deck.

Since the system is designed to cancel low-frequency sound, it doesn't use
any of the audio system's tweeters. The ANC™ dramatically reduces the
booming sound of the exhaust, front and rear. In the frequency range below 100
hertz, ANC™ results in an impressive 10 dB reduction in noise level.


An overhead console in the RL incorporates a variety of useful features. Controls
for the standard HomeLink® system and other overhead console features include
controls for interior lighting, power sunroof, power rear sunshade and remote
retracting rear head restraints.


Like the TL, with its innovative and widely heralded audio system, the RL comes
standard with a DVD-Audio system that is engineered to advance the state of
the art in production car audio. The ultra-sophisticated system of the RL provides
the driver and passengers with a new level of audio enjoyment utilizing the
Bose® Cabin Surround® sound system.

Engineered specifically for the RL, the Acura/Bose 10-speaker Surround Sound
System with 6-disc CD, DVD-Audio and DTS changer and AM/FM tuner delivers surround
sound to all seating positions and features standard XM® Satellite Radio.
XM® provides more than 170 channels (all music channels are commercial-free)
of digital program material with near-CD quality sound. A text display on the
navigation screen provides information on the program material. XM® provides
virtually uninterrupted coverage within 48 contiguous states and some of Canada,
and a one-year subscription is included with the RL. (Note: XM® Satellite
Radio is not installed on RL models sold in Alaska and Hawaii as service for
these states does not exist at this time.)

The RL has a 6-disc in-dash changer that can play DVD-Audio, CD, and MP3 media.
DVD-Audio is the next step in audio reproduction technology. Many new music
releases are being issued in this new format, and many older recordings are
being re-mastered and reissued to take advantage of the superior sound that
DVD-Audio offers. With over 500 times higher resolution than CD audio, DVD audio
delivers smoother, fuller and far more accurate sound. (Note: The system will
not play DVD movies, DVD-Video or DVD-R/RW.)

To improve sound quality when playing CDs, the system includes Centerpoint®
logic, which creates simulated surround sound from the two channels of CD data.
Another feature, Audiopilot®, automatically adjusts the audio signal in
response to exterior noises. Audiopilot® monitors the sound in the RL cabin
using the same microphone used for the Active Noise Cancellation™ system
(ANC), and then the system adjusts the audio output to compensate. Centerpoint®,
Audiopilot®, balance, fader and other functions can be accessed via the
Interface Dial. Controls for key audio system functions are positioned within
fingertip reach on the RL steering wheel. Select audio system functions can
also be accomplished via voice commands.

For precise audio imaging and impressive sound for listeners in the front
and rear seats, 10 speakers are strategically located throughout the RL cabin.
Each front door has a 6.5-inch full-range speaker and a separate 1.5-inch tweeter.
A 2.5-inch twiddler is centered on the top of the instrument panel. Each rear
door has a 6.5-inch full-range speaker; the rear parcel shelf has a 2.5-inch
twiddler on each side, with a big 9-inch woofer centrally located beneath the
back glass. A total of 260 watts drives the 10-speaker system.


Like all Acura's, the RL has a standard Bluetooth® HandsFreeLink®
hands free phone interface that is designed to work with many recently manufactured
Bluetooth®-enabled mobile phones (sold separately). Bluetooth® is a
radio frequency-based cable replacement technology that lets portable devices
like mobile phones, PDAs, laptops and other devices communicate wirelessly.
The RL system is compatible with Bluetooth® -enabled cell phones that have
the Hands Free Profile (HFP). Some early Bluetooth® -enabled phones do not
have this communications protocol, but most all newly released phones should
have the HFP. After the driver completes a one-time "pairing" process,
the RL can communicate wirelessly and securely with the driver's cell phone
when it is within approximately 10 feet of the car. The phone needs to be on,
but can be stowed in a pocket, briefcase, purse, or anywhere inside the RL cabin.

Bluetooth® HandsFreeLink® allows the driver to send or answer telephone
calls without removing hands from the steering wheel. When a call comes in,
the number of the incoming caller is displayed on the Multi-Information Display
located in the speedometer face. The phone ring tone is also played over the
audio system. If the driver chooses to answer the call, a press of the steering
wheel-mounted "Pick up" button mutes the audio system and the incoming caller
is heard over the audio system speakers. An overhead HandsFreeLink® system
cancels "echo effect" and reduces background noise to improve the transmission
quality of the driver's speech.

To send a call hands free, the driver can dial the number by voice, again
using fingertip controls mounted on the steering wheel to activate the system.
The driver also can store frequently called numbers with voice tags in the system's
memory. Up to six different compatible mobile phones can be paired with the
Bluetooth® HandsFreeLink® system at one time.

RL models in the 48 contiguous states feature the AcuraLink™ satellite
communication system with real-time traffic (when equipped with the RL with
Technology Package).

AcuraLink™ allows for two-way communication between Acura and the vehicle,
providing customers with the latest information specific to their vehicle. In
cases where communication to and from the Acura Telematics server is needed,
the owner's Bluetooth® phone is used (once the owner has enabled its data-transmission

AcuraLink? messages consist of a limited amount of text plus expanded details
via Text-To-Speech. Each message is prioritized by importance. High priority
messages are displayed immediately upon receipt. Other messages trigger an icon
on the RL navigation display. Some low priority messages show up only on vehicle
start-up to avoid distraction. In all cases, the RL owner can choose to read
or listen to the message immediately, or archive it to be retrieved later.

A wide variety of messages can be sent to the RL, including Maintenance Minder
(detailed information regarding your next required maintenance), Quick Tips
(information to help you maximize the benefit and enjoyment of RL features),
Feature Guide (supplements to the Owner's Manual), Diagnostic Info (detailed
information and instruction should an onboard system issue arise), and information
regarding a service or repair required. The RL owner has complete control over
the types of messages they receive. All AcuraLink™ preferences can be
set via the Owner Link web site.

Since the system allows two-way data communication between the RL and the
Acura Telematics Server, AcuraLink™ can provide the owner with vital information
that previously has been unavailable. For example, if a warning light should
appear on the RL instrument panel, AcuraLink™ can be configured to automatically
send a trouble code along with the sensor data associated with the fault to
the Acura Telematics Server, which analyzes the code, then sends a message back
to the RL, such as "A software issue has been detected. It is OK to continue
driving. The repair is currently being developed, so you do not need to visit
your dealer at this time." You will receive another AcuraLink™ message
when it is time to visit your dealer to have the system repaired. This way,
the owner knows if a particular fault is serious enough to cancel a trip, if
it can be dealt with later or if it requires special driving techniques. An
icon on the RL navigation display screen indicates an incoming message.

A wide variety of messages can be sent to the RL, including Maintenance Minder,
Quick Tips, Feature Guide and Diagnostic Info. The RL owner can set their preferences
for the types of messages they receive in their RL via the Owner Link Website.

Since the system allows two-way data communication between the RL and the
Acura Telematics Server, AcuraLink can provide the owner with vital information
that previously has been unavailable. For example, if an ABS/BRAKE warning light
should appear on the RL instrument panel, AcuraLink™ will automatically
send a trouble code to the Acura Telematics Server (if the customer selects
this preference), which interprets the code, then sends a message back to the
RL, such as "ABS and EBD shut down! Drive slowly. Avoid sudden hard braking."
This way, the owner knows if a particular fault is serious enough to cancel
a trip, if it can be dealt with later or if it requires special driving techniques.
The data connection is enabled even if the monthly XM® service package is
not in effect.


The navigation screen can display up-to-the-minute traffic information including
flow (traffic speed where available), accidents, unusual incidents, construction
and weather on freeways in 76 major metropolitan areas. The information is aggregated
by NAVTEQ™ from multiple sources including police and highway patrol accident
reports and transportation departments, and then is transmitted by XM satellites
to the RL where it is graphically displayed on the navigation system from a
1⁄2 to 5 mile scale.

The RL owner can click on an icon on the map to see incident details or select
"Traffic Incidents" by pushing "enter" on the Interface Dial. Traffic information
is continuously updated, allowing drivers to avoid congestion en route and choose
the fastest path to their destination.

With the average rush-hour commuter spending over 50 hours a year sitting
in traffic, the system gives RL owners a useful time saving tool on freeways.
Unlike radio or television traffic reports, the real-time traffic system provides
a constant flow of relevant information reflecting conditions along a driver's
chosen route. Real-time traffic data services are offered on a subscription
basis for a nominal fee following the 3-month free trial period. In addition
to the on-screen traffic information, RL owners who maintain their XM® Satellite
Radio service also receive more general audio traffic information that runs
on a 2-3 minute loop in selected metropolitan areas.

System Operation

Based on positioning data from up to 12 orbiting Global Positioning Satellites
(GPS), the Acura Navigation System with Voice Recognition tracks the vehicle's
position. If the GPS antenna is blocked by a tunnel, tall building or parking
garage, an internal gyroscopic system and a speed sensor track the location
of the vehicle to keep the mapping information current and reliable until satellite
reception is restored. A DVD is located in the trunk in the system's ECU. Updated
DVD data discs are available on an annual basis on-line or by calling a toll-free

The navigation system can be controlled by voice or by the Interface Dial.
For voice operation, the driver simply presses the "Talk" button on
the steering wheel and says any of a number of preset command phrases. The system
responds to 685 command phrases, as well as to spoken city and street names.

When the "Talk" button is pressed, the audio system is automatically muted,
and an overhead microphone receives the command from the driver. Commands can
be given in plain English, like "Display gas stations", "Find nearest hospital",
or "Find nearest Chinese restaurant." You can choose to display points of interest
on the map (like restaurants or grocery stores, for example), or have the system
provide turn-by-turn navigation—all by voice command. The extensive point-of-interest
database includes phone numbers, which can be dialed easily by using the Bluetooth®
HandsFreeLink® system and the driver's cell phone.

The Acura Navigation System with Voice Recognition can also be controlled
via the Interface Dial by choosing menu options or spelling out a word (e.g.,
an address, business name or place) using the Interface Dial much like a computer
mouse to select characters from an on-screen keypad. The onboard database includes
a Zagat Survey Restaurant Guide. The Interface Dial makes it easy to operate
the system as well as to find and select destinations. Voice recognition capability
saves time and simplifies operation of the system. Sophisticated voice recognition
technology allows the RL owner to simply speak city and street names aloud,
and the system responds by displaying matches available in the database.


For 2008, Acura again offers an optional Technology Package with CMBS™
and PAX® Tires for the RL that includes Adaptive Cruise Control (ACC). This
new vehicle speed and distance control system uses a grille-mounted millimeter-wave
radar unit to monitor the distance between the RL and the vehicle directly ahead.
Like a conventional cruise control system, the RL's ACC can maintain a pre-set
speed. But in addition, by combining radar data with data from speed sensors,
ACC can regulate the RL's speed to maintain a pre-set following distance interval
(measured in seconds) between it and the vehicle directly ahead. The system
is designed for use on open highways and works only when the RL is traveling
over 25 miles per hour.

The system is activated by pressing the "ACC" button on the upper right-hand
spoke of the steering wheel. When this button is pushed, "ACC" will appear on
the Multi- Information Display located directly below the speedometer indicating
that the system has been turned on. To select the ACC cruising speed, the driver
accelerates to that speed and presses the "Decel/Set" button, which is also
located on the upper right-hand spoke of the steering wheel. Once selected,
the chosen cruising speed is shown on the Multi-Information Display.

The following distance interval is selected by pressing the "Distance" button
on the lower right spoke of the steering wheel. Using this button, the driver
can choose one of three following intervals: approximately one second, approximately
1.5 seconds or approximately two seconds, based on the speed of the RL along
with the following distance the driver wants to maintain from the car directly
ahead. Each time the button is pressed, a "vehicle-shaped" icon on the Multi-information
display changes to reflect the chosen following interval:

  • One bar representing approximately a one-second interval

  • Two bars representing approximately a 1.5 second interval

  • Three bars representing approximately a two-second interval

Once the system is activated, the system's electronic control unit (ECU) adjusts
the throttle and applies light braking to maintain the chosen following distance
interval between the RL and the car directly in front of it. If a vehicle from
another lane cuts in front of the RL (between the RL and the car that it has
been following) the system will beep and the "vehicle" icon will flash on the
Multi-Information Display to alert the driver that a new vehicle has been detected.
The system then adjusts the throttle and applies light braking to maintain the
pre-set following interval between the RL and the new vehicle. A vehicle icon
will appear each time a vehicle moves into the ACC system's range. Conversely,
when a vehicle moves out of the system's range, the icon changes to an "outlined"

If the vehicle directly ahead of the RL brakes suddenly, a series of beeps
will sound and the word "BRAKE" will appear on the Multi-Information Display
warning the driver to apply the brakes.

If the vehicle directly in front of the RL accelerates out of the radar's
detection zone or moves to another lane, and another vehicle is not within the
system's range, ACC will gradually accelerate the RL until the pre-set cruising
speed is achieved. When a vehicle moves out of range, the "vehicle icon" on
the Multi-Information Display will change from solid to outline.

The driver can switch between ACC and conventional cruise control by using
the "Distance" button located on the steering wheel. Cruise control system status
is displayed continuously on the Multi- Information Display.

Because the ACC system's millimeter-wave radar can be affected by rain, snow,
fog and other types of inclement weather, the ACC system should not be used
during these conditions.


The RL features a Keyless Access System with driver recognition for driver's
seat, steering wheel, outside mirrors, climate control, audio system settings
and presets, and select navigation system settings. This feature allows the
RL owner to gain access to the car without ever having to unlock it with the
remote transmitter or key. The keyless remote has an electronic unique digital
identity. The car can be unlocked when the driver grasps one of the front doors
with the keyless remote in his/her possession.

Once the driver has opened the door and is seated, the Keyless Access System
allows the RL to be start by rotating the ignition switch without inserting
a key into the ignition.

To unlock the door, the driver must have the keyless remote in their possession.
The remote can remain in a pocket or briefcase as it isn't necessary to have
it in hand. The driver simply approaches the car and grasps the door handle
to the door.

To lock the doors upon leaving the car, simply touch the raised dimple on
outside of the door handle. Alternatively, you can press the Lock button on
the keyless remote. All doors will lock simultaneously.

Approaching the driver's side allows the opening of the driver's door only
whereas when approaching the passenger's side all four doors can be opened.
Via the Multi- Information Display's selectable unlocking feature, the RL owner
can preset a preference to have all four doors unlock when the driver's door
is engaged.

To open the trunk, simply approach with the remote and pull the lever as it
will automatically unlock so you can open the lid. The system will not allow
the recognized transmitter to be locked in the trunk.


The Acura RL comes with two keyless remotes. Each keyless remote can be set
with a unique preference, for instance to accommodate the preferences of a husband
and wife.

The preferences include driver seat, steering wheel and mirror positions along
with select HVAC functions. Other preferences include turning entry lights on
or off, audio pre-sets, air conditioning, and navigation system settings. In
the event both owners plan to use the car at the same time, the RL will recognize
the keyless remote that approaches first.

Built-in Key

A built-in mechanical key is provided as a back up in the event that the keyless
remote battery should fail, although the vehicle will signal the driver when
the remote battery is low. In this case the RL can be started with the built-in
key. For security purposes when using a valet parking service, you can push
a trunk lockout switch inside the glove box, and then lock the glove box and
the trunk pass-through with the key. Take the built-in key from the keyless
remote and keep it, then give the keyless remote to the attendant. The valet
will be unable to unlock the glove compartment or trunk using the keyless remote.
