Fog Lamps
If your vehicle has fog lamps you can use them for
better vision in foggy or misty conditions. Your parking
lamps and/or low-beam headlamps must be on for your
fog lamps to work.
The fog lamp button is located on the left side of your
instrument panel.
#
(Fog Lamps): Press the button to turn the fog lamps
on. An indicator light will glow near the button when the
fog lamps are on. Press the button again to turn
them off.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on the headlamps.
The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after you
restart the vehicle, you will need to press the fog lamp
button again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Exterior Cargo Lamps
The cargo lamp can be used if more light is needed in
the cargo area of the vehicle or in the top-box storage
units. Some vehicles will only have a cargo lamp in the
driver side top box.
The cargo lamps come on by turning on the interior
dome lamps.
Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D (Instrument Panel Lights) : Push the knob to extend
and then turn clockwise or counterclockwise to brighten
or dim the instrument panel lights and the radio display.
This only works if the headlamps or parking lamps
are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
