3. Pull the cover downward to
disengage the upper
attachments.
To reinstall the hitch cover:
1. Hold the cover at a 45 degree
angle to the vehicle and push
the upper tabs in the hitch
cover into the slots in the
fascia.
2. Move the bottom of the cover
forward until the lower tabs line
up with the lower fascia slots.
3. Snap the hitch cover into place
by pushing the upper corners
forward.
4. Reinstall the two bolts on the
lower tabs by turning
clockwise.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Always leave just enough slack so
the rig can turn. Never allow safety
chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 454 kg (1,000 lb) needs to have
its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted, and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If you do, both brake
systems will not work well, or at all.
Trailer Wiring Harness
Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle's frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer.
The seven-wire harness contains
the following trailer circuits:
Yellow/Gray: Stop/Turn
Signal Left
Green/Violet: Stop/Turn Signal
Right
Gray/Brown: Parking Lamps
White/Green: Back-up Lamps
Red/Green: Battery Feed
Black: Ground
Blue: Electric Brakes*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.
They should be connected by your
dealer or a qualified service center.
If the back-up lamp circuit is not
functional, contact your dealer.
Electric Trailer Brake Control
Wiring Provisions
These wiring provisions for an
electric trailer brake controller are
included with the vehicle as part of
the trailer wiring package. The
