How does the automatic light off system work?

Your lights are important for driving at night, in the rain and in many other situations. However, if you leave the lights on after turning the engine off, they can quickly drain your battery. Your car has a system designed to prevent this from happening called the automatic light off system. Here’s how it works:

  • The system will automatically turn off the lights (both headlights and taillights) within 30 seconds of you turning the engine off and opening the driver front door (only if the ignition switch is in the off or accessory positions).

Tips

  • The system works the same on cars with standard ignitions and those with the smart key system.

  • Turn your lights back on by turning the switch to either the parking light or headlight position with the ignition set to on.
