Fog Lamps - GMC Yukon XL Denali Owner's Manual

6-6 Lighting
Holding the turn signal lever for
more than one second will cause
the turn signals to flash until you
release the lever.
The lever returns to its starting
position whenever it is released.
If after signaling a turn or a lane
change the arrows flash rapidly or
do not come on, a signal bulb could
be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See Fuses and Circuit Breakers on
page 10 37.
Turn Signal On Chime
If the turn signal is left on for more
than 1.2 km (0.75 mi), a chime will
sound at each flash of the turn
signal and the message TURN
SIGNAL ON will also appear in the
Driver Information Control (DIC). To
turn the chime and message off,
move the turn signal lever to the off
position.

Fog Lamps

For vehicles with fog lamps, the
control is located next to the exterior
lamps control on the instrument
panel to the left of the steering
column.
(Fog Lamps): Press the button
to turn the fog lamps on or off.
A indicator light comes on in the
instrument panel cluster. The
ignition must be in the ON/RUN
position for the fog lamps to
come on.
When the fog lamps are turned on,
the headlamps automatically
turn on.
When the headlamps are changed
to high-beam, the fog lamps also go
off. When the high-beam headlamps
go off, the fog lamps will come on
again.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.
