    Air bag collision sensors

    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. Installing bumper guards with nongenuine Hyundai or non-equivalent parts may adversely affect the collision and airbag deployment performance. Press the Engine Start/Stop button to the OFF or ACC position and wait for 3 minutes when the vehicle is being towed to prevent inadvertent air bag deployment. Have all air bag repairs performed by an authorized HYUNDAI dealer.
