Interior Lamps
Instrument Panel Brightness
The control for the instrument panel lights 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.
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.

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.

after the key is removed from the ignition.

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
and off.

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 or trunk lamp. If you leave any of these
lamps on, they will automatically turn off after
10 minutes, if the ignition is 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 turning off automatically.
