Light Sensor

Do not cover it up. If you do, it will sense darkness and
®
the Twilight Sentinel lighting will turn on.

Exterior Lighting Battery Saver

If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition
is turned to LOCK and a door has been opened.
This protects against draining the battery in case you
have accidentally left the headlamps or parking
lamps on. If you need to leave the lamps on for more
than 10 minutes, use the manual control to turn the
lamps back on after the ignition is turned to LOCK and
any door is opened. To delay the lamps from turning
off, see Twilight Sentinel
Your Twilight
®
Sentinel and DRL work
with the light sensor
located on top of the
instrument panel.

Instrument Panel Brightness

The brightness of the instrument panel lights can be
adjusted by sliding the INTERIOR lever from LO to HI.
The instrument panel lights will be on only while the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the
way to HI.

Courtesy Lamps

If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps
on by sliding the INTERIOR lever all the way to HI.
The lever for this feature is
located to the left of the
steering column.
