2009 Audi S4 Safety Features
Anti-lock brakes
ABS brakes automatically sense when a tire has stopped rotating under extreme braking, and will modulate the brake pressure to allow the tire to rotate. This increases the vehicles ability to turn while braking.
Stability control
Stability control automatically senses when the vehicles handling limits have been exceeded and reduces engine power and/or applies select brakes to help prevent the driver from losing control of the vehicle.
Front-impact airbags
Front-impact airbags for the driver and passenger have been designed to protect the head during a frontal crash.
Side impact airbags
Side impact airbags for the front seats have been designed to protect the torso during a side impact collision.
Knee airbags
Knee airbags help to protect the occupants lower extremities from serious injury in the event of an accident.
Pretensioners
Seatbelt pretensioners automatically tighten seatbelts to place the occupant in the optimal seating position during a collision.
Security system
The vehicle is equipped with a means of anticipating and/or detecting unwanted vehicle intrusion. The vehicle is equipped with an ignition disable device that will prevent the engine from starting if the correct original manufacturer key is not used.
