Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes after the ignition is turned to LOCK/OFF, if the parking lamps or headlamps have been manually left on. This protects against draining the battery.
To restart the10 minute timer, turn the exterior lamp control to OFF and then back to the parking lamp or headlamp position.
To keep the lamps on for more than 10 minutes, the ignition must be in the ACC/ACCESSORY or ON/RUN position.
