Fog Lamps
#
(Fog Lamps): For vehicles with fog lamps,
the button is located on the exterior lamps control.
The exterior lamps control is located on the instrument
panel to the left of the steering column.
The ignition must be in the ON/RUN position for the fog
lamps to come on.
Press # to turn the fog lamps on or off. A light will
come on in the instrument panel cluster.
When the headlamps are changed to high-beam, the
fog lamps also go off.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Instrument Panel Brightness
D (Instrument Panel Brightness): The knob with this
symbol on it is located next to the exterior lamps control
to the left of the steering wheel. Push the knob in all the
way until it extends out and then turn the knob clockwise
or counterclockwise to brighten or dim the lights. Push
the knob back in when finished.
Courtesy Lamps
When a door is opened, the courtesy lamps
automatically come on. They make it easy for you to
enter and leave your vehicle. You can also manually
turn these lamps on by fully turning the instrument
panel brightness control clockwise.
The reading lamps, located on the rearview mirror,
can be turned on or off independent of the automatic
courtesy lamps, when the doors are closed.
Dome Lamp
The center mounted dome lamp overhead comes on
when a door is opened. This lamp can also be turned
on by turning the instrument panel brightness control
clockwise.
