Your vehicle is equipped with a side air bag in each front seat. The purpose of the air bag is to provide the vehicle's driver and the front passenger with additional protection than that offered by the seat belt alone.
The side air bags are designed to deploy only during certain side impact collisions, depending on the crash severity, angle, speed and point of impact.
The side and curtain air bags on both sides of the vehicle may deploy if a rollover or possible rollover is detected.
The side air bags are not designed to deploy in all side impact or rollover situations.
WARNING
To reduce the risk of serious injury or death from an inflating side air bag, take the following precautions:
