Fog Lamps (If Equipped) - GMC SIERRA 1997 Manual

Fog Lamps (If Equipped)
If you
have fog lamps, 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 switch is on
the lower edge of your
instrument panel.
Press the ribbed top part of the switch to turn the fog
lamps on. Press the bottom of the switch to turn them
off. A light will glow in the switch when the fog lamps
are
on.
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 your headlamps.
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.
