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 left on. This protects against
draining the battery. The battery saver does not
work if the headlamps are turned on after the ignition is
turned to LOCK/OFF.
To keep the lamps on for more than 10 minutes, turn
the lamps back on with the exterior lamp control.
Instrument Panel Brightness
Turn the knob clockwise
or counterclockwise to
brighten or dim the
interior lights.
To turn on the dome lamps, turn the knob completely
clockwise as far as it will go. The dome lamps stay
on until they are turned off.
Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control, when a door is opened or if the transmitter
unlock button is pressed. If activated by the transmitter,
the lighting stays on for about 25 seconds. The entry
lighting system uses the light sensor on the instrument
panel; so it must be dark outside in order for the
lamps to turn on. The lamps turn off about 25 seconds
after the last door is closed. They dim then turn off
if the ignition key is turned to ON/RUN. They
immediately turn off if the power locks are used.
Parade Dimming
This feature does not let the instrument panel backlight
dim during daylight hours while the key is in the
ignition and the headlamps are on. Parade dimming
automatically works with the light sensor, located on top
of the dashboard. If it is dark enough outside and the
parking lamps are on, the backlight on the instrument
panel can be adjusted by turning the instrument
panel brightness knob clockwise or counterclockwise to
brighten or dim the lighting. SeeInstrument Panel
Brightness on page 3-18.
