Interior Lamps
Instrument Panel Intensity Control
You can brighten or dim the instrument panel cluster
lights by moving the thumbwheel up to increase
intensity and down to decrease intensity.
The thumbwheel, which
controls the intensity of the
instrument panel lights, is
located on the instrument
panel to the left of the
steering wheel.

When the thumbwheel for the instrument panel intensity
control is moved up, the dome lamp, and the mirror
reading lamps (if equipped) will turn on. Move the
thumbwheel down to turn the lamps off.
Illuminated Entry/Exit System
When you lift the driver's door handle or open any door,
the lamps inside your vehicle will go on. These lamps
will fade out after about 10 seconds after all of the doors
have been closed or when the ignition is turned to ON.
These lamps will also go on when you press the trunk
release, UNLOCK button or the horn symbol on the
optional keyless entry system transmitter (if equipped).
The lamps inside your vehicle will stay on for about
10 seconds after your key is removed from the ignition
to provide an illuminated exit.
