Hyundai Elantra: Air Bag - Advanced Supplemental Restraint System / Why Didn't My Air Bag Go Off in a Collision?

There are certain types of accidents in which the air bag would not be expected to provide additional protection. These include rear impacts, second or third collisions in multiple impact accidents, as well as low speed impacts. Damage to the vehicle indicates a collision energy absorption, and is not an indicator of whether or not an air bag should have inflated.

WARNING

To reduce the risk of an air bag deploying unexpectedly and causing serious injury or death:

• Do not hit or allow any objects to impact the locations where air bags or sensors are installed.
• Do not perform maintenance on or around the air bag sensors. If the location or angle of the sensors is altered, the air bags may deploy when they should not or may not deploy when they should.
• Do not install bumper guards or replace the bumper with a non-genuine HYUNDAI parts. This may adversely affect the collision and air bag deployment performance.
• Place the ignition switch in the LOCK/OFF or ACC position when the vehicle is being towed to prevent inadvertent air bag deployment.
• Have all air bag repairs conducted by an authorized HYUNDAI dealer.
