■Headlight control sensor (if equipped)
■ Automatic light off system
● When the headlights come on: The headlights and tail lights turn off 30
seconds after a door is opened and closed if the “POWER” switch is
turned to ACCESSORY mode or turned off. (The lights turn off immedi-
ately if on the key is pressed after all the doors are locked.)

light switch off once and then back to or .
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be
interrupted.
