Default Fit: 2009 Honda Fit - Safety

The new Fit: advanced performance in a compact form

With a comprehensive and evolving approach to vehicle safety, Honda seeks to make cars safer for occupants. Some of the new Fit's key safety features are Advanced Compatibility Engineering™ (ACE™), which provides improved protection for vehicle occupants and helps mitigate damage to other vehicles; dual-stage, dual-threshold front airbags, front-side airbags with a passenger-side Occupant Position Detection System (OPDS) and a side curtain airbag system; and a pedestrian-injury mitigation front body design.

Standard safety features on all models

• Advanced Compatibility Engineering™ (ACE™) body structure NEW

• Anti-lock brake system (ABS), Electronic Brake Distribution (EBD) and brake assist

• 3-point seat belts in all seating positions

• Front seat belts with automatic tensioning system

• Driver and front passenger Active Head Restraints NEW

• Driver and front passenger seat belt reminder

• Dual-stage, dual-threshold front airbags (SRS)

• Front side airbags with Occupant Position Detection System (OPDS)

• Side curtain airbag system (front and rear seats)

• Tire Pressure Monitoring System (TPMS)

• Side-impact door beams

• Pedestrian-injury mitigation design in the front of the vehicle

• Outboard Lower Anchors and Tethers for Children (LATCH) system (both rear seats)

• Child-proof rear door locks

Protecting occupants during collisions

The new Fit has an exceptionally strong body, built around the latest application of Honda's Advanced Compatibility Engineering™ (ACE™) body structure technology. New on the Fit for 2009, the revolutionary ACE™ body structure makes the new Fit highly effective at absorbing the energy of a frontal crash. It also helps minimize the potential for under-ride or over-ride during head-on or offset frontal collisions with a larger or smaller vehicle. Using a sophisticated computer-assisted design process, the ACE™ body structure creates a network of fully integrated load-bearing elements that helps attenuate peak impact forces by more evenly distributing them across a relatively large area in the front of the vehicle.


Unlike most conventional designs that direct frontal crash energy only to the lower load-bearing structures in the front end, the ACE™ body structure actively channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. By engineering specific 'pathways' that help distribute these frontal impact forces throughout a greater percentage of the vehicle's overall structure, the ACE™ body structure can more effectively route them around and away from the passenger compartment to help limit cabin deformation and further improve occupant protection. Integral to the ACE™ body structure concept is its unique front main structure composed of polygonal frame members.

Newly designed lower dashboard cross-member


The dashboard's lower cross-member has been given a rounded, bow shape to disperse impact energy absorbed by the front frame rail on the impact side through both floor frame rails including the one on the opposite side. This configuration further improves the efficiency with which the impact of a collision is dispersed and absorbed.

Pedestrian-injury migitation: impact-absorbing front body design

The Fit is designed to help absorb energy in the event of a frontal collision with a pedestrian. Research by Honda shows that the following features can dramatically reduce the level of pedestrian injury in a collision.


1. Impact-energy absorbing hood

Space is provided with engine room components for the hood to bend and deform, absorbing impact energy.

2. Deformable hood hinges

The hood hinges are designed to deform easily.

3. Impact energy-absorbing front fenders

The front fender mounts and brackets are designed to deform easily to help absorb impact energy.

4. Deformable windshield wiper pivots

The wiper pivots are designed to deform and break away easily.

5. Impact energy-absorbing front bumper

The front bumper beam is designed to serve as a cushion that helps absorb impact energy.

Protecting occupants from impacts on all sides

Already a leader in vehicle safety, Honda continues to implement leading airbag technology throughout the product lineup. Dual-stage, dual-threshold front airbags, front side airbags with passenger-side Occupant Position Detection System (OPDS) and side-curtain airbags are standard equipment on all Fit models. In addition, the new Fit incorporates 3-point seat belts in all seating positions. Front seatbelts feature an automatic tensioning system and adjustable anchors.

Dual-stage, dual-threshold front airbags

Both the driver and front passenger are protected by advanced front airbags that incorporate dual-stage and dual-threshold activation technology. These features work together in the event of a deployment while helping minimize injuries sometimes caused by airbags. Honda's sophisticated dual-stage, dual-threshold system is designed to optimize the deployment rate to match the severity of a crash event.

Front side airbags with front passenger Occupant Position Detection System (OPDS)

Side airbags mounted in the outboard area of each front seatback are designed to provide upper torso protection in the event of a severe side impact. In addition, the front passenger's seat is equipped with an Occupant Position Detection System (OPDS), an innovative system designed to deactivate the side airbag if a child or small-statured adult leans into the side airbag deployment path.


Side curtain airbag system (front and rear)

The side curtain airbag system is designed to rapidly deploy in the event of a side collision to help protect the heads and necks of occupants. The large airbag covers almost the entire side window area, utilizing a low-temperature, compressed gas inflator to inflate. No fewer than five sensors are used to detect side collisions and determine optimum timing for airbag deployment.
