112 Lighting
Turn and Lane-Change Signals
An arrow on the instrument cluster flashes
in the direction of the turn or lane change.
Move the turn signal lever all the way up or
down to signal a turn.
Raise or lower the lever for less than
one second until the arrow starts to flash to
signal a lane change. This causes the turn
signals to automatically flash three times.
Holding the turn signal lever for more than
one second will cause the turn signals to
flash until the lever is released.
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.
Replace any burned out bulbs. If a bulb is
not burned out, check the fuse. SeeFuses
and Circuit Breakers 0277. Turn Signal On Chime
If the turn signal is left on for more than
1.2 km (0.75 mi), a chime sounds at each
flash of the turn signal. The message TURN
SIGNAL ON will also appear in the Driver
Information Center (DIC). To turn the chime
and message off, move the turn signal lever
to the off position.Fog Lamps
The Fog Lamps control is in the Controls App
on the infotainment home screen. Select
Controls > Lights.
To operate, select the following option:
9:
Press to turn on or off. An indicator
light on the instrument cluster comes on
when the fog lamps are on.
If the fog lamps are turned on while the
exterior lamp control is set to Auto, the
lamps come on automatically.
The vehicle and the parking lamps or
headlamps must be on for the fog lamps
to work.
Some localities have laws that require the
headlamps to be on along with the fog
lamps. Fog lamps should only be used in foggy or
misty conditions to allow the drivers behind
you to see your vehicle.
Off-Road Lamps (AT4X Only)
If equipped, this button includes wiring
provisions for a dealer or a qualified service
center to install electrical accessories, such
as Off-Road lamps.
The button on the center stack activates the
accessory.
When the wiring is connected to Off-Road
lamps, pressing the button will activate the
lamps.
For information on installation, see
www.gmupfitter.com or contact your dealer.
See
Add-On Electrical Equipment 0251.

Trailer Connection and Lamp Messages
When a trailer is properly connected and
working, no trailer connection or lamp
messages appear on the DIC. However; if
the vehicle detects an issue with a trailer
connection or lamp, you may see the
following DIC message(s):
.TRAILER DISCONNECTED CHECK
CONNECTION appears when a connected
trailer is disconnected. It appears
immediately when the vehicle is on,
or upon the next start-up if the trailer
was disconnected while the vehicle was
off. Check the trailer connection as
appropriate.
.CHECK TRAILER XXX LAMP appears when
there is a detected lamp or wiring fault
on the trailer. Check the trailer wiring and
lamps.
Turn Signals When Towing a Trailer
When properly connected, the trailer turn
signals will illuminate to indicate the vehicle
is turning, changing lanes, or stopping.
When towing a trailer, the arrows on the
instrument cluster will illuminate even if the
trailer is not properly connected or the bulbs
are burned out.
Tow/Haul Mode
For instructions on how to enter Tow/Haul
Mode, see Tow/Haul Mode 0178.
Tow/Haul assists when pulling a heavy
trailer or a large or heavy load.
Tow/Haul Mode is designed to be most
effective when the vehicle and trailer
combined weight is at least 75% of the
vehicle's Gross Combined Weight Rating
(GCWR). See “Weight of the Trailer” under
Trailer Towing 0231.
Tow/Haul Mode is most useful when towing
a heavy trailer or carrying a large or
heavy load:
.through rolling terrain.
.in stop-and-go traffic.
.in busy parking lots.
Operating the vehicle in Tow/Haul Mode
when lightly loaded or not towing will not
cause damage; however, it is not
recommended and may result in unpleasant
engine and transmission driving
characteristics and reduced fuel economy.
