Lighting 105
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 0258.
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

Driving and Operating 225
State or local regulations may require
trailers to have their own braking system if
the loaded weight of the trailer exceeds
certain minimums that can vary from state
to state. Read and follow the instructions for
the trailer brakes so they are installed,
adjusted, and maintained properly. Never
attempt to tap into your vehicle's hydraulic
brake system. If you do, both the vehicle
anti-lock brakes and the trailer brakes may
not function, which could result in a crash.
Trailer Wiring Harness
For vehicles not equipped with heavy-duty
trailering, a harness is secured underneath
the left side of the vehicle, next to the spare
tire. The harness requires the installation of
a trailer connector, which is available
through your dealer. The seven-wire harness
contains the following trailer circuits:
.Yellow: Left stop/turn signal
.Green: Right stop/turn signal
.Brown: Taillamps/parking lamps
.Black: Ground
.Gray: Back-up lamps
.Orange: Battery feed
.Blue: Trailer brakeTo help charge a remote (non-vehicle)
battery, press the Tow/Haul Mode button
on the center stack. If the trailer is too light
for Tow/Haul Mode, turn on the headlamps
to help charge the battery.
Trailer Brake Control Wiring Harness
A four-wire harness, without connector, is
secured behind the left side kick panel. The
harness contains the following circuits:
.Red/Green: Battery feed
.Black: Ground
.White/Blue: Brake signal to controller
.Blue: Trailer Brake power to trailer
connectorTo remove the left side kick panel, start at
the front of the panel pulling toward the
rear of the vehicle and lift upward to
disengage the integral clips.
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 0194.
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 0219.
Tow/Haul Mode is most useful when towing
a heavy trailer or carrying a large or
heavy load:
.through rolling terrain.
