Interior Lamps
Instrument Panel Brightness Control
This feature controls the instrument panel lights.
The control for this feature is located on the exterior
lamps control. Your parking lamps must be on for this
feature to work. Turn the control clockwise to brighten
the lights or counterclockwise to dim them.
Courtesy Lamps
When any door is opened, several lamps come on. These
lamps are courtesy lamps. They make it easy for you to
enter and leave your vehicle. You can also turn these
lamps on by turning the exterior lamps control all the
way clockwise.
Some of the lamps have switches so you can turn them
on, even when the doors are closed. These lamps are
reading lamps.
Illuminated Entry (If Equipped)
Your courtesy lamps will come on and stay on for a set
time whenever you press UNLOCK on the remote
keyless entry transmitter (if equipped).
If you open a door, the lamps will stay on while it's open
and then turn off automatically about 25 seconds after
you close it. If you press UNLOCK and don't open a
door, the lamps will turn off after about 40 seconds.
Illuminated entry includes a feature called theater
dimming. With theater dimming, the lamps don't just
turn off at the end of the delay time. Instead, they slowly
dim after the delay time until they go out. The delay
time is canceled if you turn the ignition key to ON or
press the power door lock switch. The lamps will dim
right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps won't come on unless
a door is opened.
