Twilight Sentinel also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel has turned on
the lamps when you turn off the ignition, the lamps will
remain on until:
. The exterior lamp switch is moved from off to the
parking lamp position.
. A delay time that you select has elapsed.
See Vehicle Personalization on page 3‑59 to select the
delay time needed. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after the
ignition is turned off. This protects against draining the
battery in case you have accidentally left the headlamps
or parking lamps on. The battery saver does not work if
the headlamps are turned on after the ignition is
turned off.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on.
