Interior Lamps
Instrument Panel Brightness
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.
Entry Lighting
Your vehicle may be equipped with courtesy lamps that
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.Entry lighting 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.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will continue to
work until one of the following occurs:
·The ignition is moved to ON,
·the doors are locked, or
·an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
3-17

Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the key is removed, interior illumination will
activate and remain on until one of the following occurs:
·The ignition is moved to ON,
·the power door locks are activated, or
·an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you'll still be able to see
the displays.
Reading Lamps
Your vehicle may be equipped with reading lamps that
are located on the assist handles in the headliner.
These lamps and the interior courtesy lamps come on
when any door is opened. Press the lens to turn
them on. Press it again to turn them off.
Dome Lamp
If your vehicle has this feature, the dome lamp will
come on when you open a door. You can also turn this
lamp on by turning the exterior lamps control clockwise
as far as it will go. Vehicles that have the optional
sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor
vanity lamps, trunk lamp or glove box lamps. If you leave
any of these lamps on, they will automatically turn off
after 10 minutes, if the ignition is moved to OFF.
The lamps won't come back on again until you do
the following:
·Turn the ignition on, or
·turn the exterior lamps control off, then on again.
If your vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off the lamps
after only three minutes.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
¯ash three times. They will remain on for one more
minute before being turned off automatically.
