All models have a Supplemental Restraint System (SRS)-a frontal-impact airbag system that protects the driver and the front seat passenger in the event of a head-on collision protecting them against fatal injuries. This is managed by the Occupant Restraint Controller or SRS, installed centrally in the car and is supported by different types of air bags such as the driver's air bag in the steering column, a knee blocker air bag for the models after 2005, the passenger air bag embedded in the instrument panel and the optional side air bags for the rear seat passengers. It is front impact sensors activated system and encompasses such parts as the clockspring and the AIRBAG readiness light. Also, seat belt pre tensioner is installed on each front seat belt retractor to boost safety features. Driver's airbag that expands almost simultaneously as soon as it is triggered by an electrical impulse, while the knee blocker airbag expands to shield the driver's knees. Larger than the driver's, the passenger airbag is attached to a steel housing that also houses the passenger knee blocker, which forms part of the structure. For enhanced occupants' protection, the outside rear doors' side-impact window airbags are located above the windows, and are deployed by the side-impact sensors installed in various locations of the vehicle. The ORC/ACM sends current to the SRS during a collision, and checks the system at start-up, its status being shown by the AIRBAG readiness light. To get the vehicle ready to work on before deployment of the air bags the ignition switch must be turned off and the negative battery terminals disconnected and it is advisable to wait for sometime then check if the back up power is depleted. This prevention is done by avoiding handling of the airbag opening within the body range and it is alsostrictly prohibited to measure the resistance of any SRS components. For component removal, the driver air bag and clockspring remain special since it involves the following: disarming the system, removal of knee bolster, disconnection of air bag electrical connector and detachment of knee blocker air bag for reassembly.

The airbag system includes an airbag module located in the center of the steering wheel, two crash sensors mounted at the front of the vehicle, and a diagnostic module containing an additional crash sensor within the passenger compartment.
