The anti-lock braking system (ABS) uses a special modulator to pulse the brakes to help prevent wheel lockup. This helps the driver retain steering control when braking hard. The Electronic Brake Distribution system (EBD) balances the front/rear braking forces.
ACE body structure incorporates a front-end frame structure that absorbs and disperses crash energy over a larger area. ACE increases Civic Hybrid passenger protection, and makes it more crash-compatible with vehicles of differing ride heights.
In a sufficient rear-end impact, the active head restraints move forward and up, reducing and /or preventing neck injury.
The solid-cell design and central placement of the nickel-metal hydride (Ni-MH) battery pack help protect it.
The Daytime Running Lights (DRL) can help increase visibility to oncoming cars, especially in rainy or foggy weather conditions.
In the event of a moderate-to-severe frontal impact, the dual-stage, dual-threshold front airbags (SRS) inflate and deflate in a fraction of a second and are designed to help prevent head and upper-body injuries.
The front and rear crush zones help provide driver and passenger protection in frontal and rear impacts.
In the event of a moderate-to-severe side impact, the side airbag inflates to help protect the driver's or front passenger's upper body. Plus the Occupant Position Detection System (OPDS) utilizes sensors in the front passenger's seatback to detect the height and seating position of the occupant. If a child or small-statured adult is leaning into the deployment path of the side airbag, sensors deactivate it.
All five seats are equipped with 3-point seat belts. The rear seat features the LATCH (Lower Anchors and Tethers for Children) mounting system for use with compatible child seats.
Front and rear 3-point seat belts with an automatic tensioning system ride across the lap and chest to help restrain occupants during sudden stops or impact.
Designed to deploy from the headliner, side curtain airbags help provide additional head-injury protection in the event of a significant side impact. The side curtain airbag is stored in a small compartment at each side of the headliner. A gas generator installed at the rear C-pillar supplies the inert gas necessary to inflate the bag through a channel along the side of the affected headliner. The airbag can fully deploy in approximately 20 milliseconds, creating a cushioning layer between the obstacle or vehicle's window and the passenger's head.
The side-impact door beams help provide protection in a side impact.
The system immobilizes the engine's fuel injection and ignition, and only a matching digital code in the ignition key can override it. When the driver puts the key into the ignition switch, the switch transmits a signal that reads the code in the key. If the key code agrees with the code in the powertrain control module (PCM), the engine starts.
