Driving Characteristics and
Towing Tips
Driving with a Trailer
When towing a trailer:
.
Become familiar with the state
and local laws that apply to trailer
towing. These requirements vary
from state to state. .
The trailer must be equipped with
brakes adequate for the intended
use. A loaded trailer weighing
more than 900 kg (2,000 lb) must
be equipped with its own brake
system, with brakes working on all
axles. Trailer braking equipment
conforming to Canadian Standards
Association (CSA) requirement
CAN3-D313, or its equivalent, is
recommended.
. Do not tow a trailer during the
first 800 km (500 mi) to prevent
damage to the engine, axle,
or other parts.
. Then during the first 800 km
(500 mi) of trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
. Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if
the transmission shifts too often
under heavy loads and/or hilly
conditions.
. Do not use Adaptive Cruise
Control when towing. .
Turn off Parking Assist and Rear
Cross Traffic Alert (RTCA) when
towing.
. The Forward Automatic Braking
System should be set to Off when
towing. See Forward Automatic
Braking (FAB) 022.
. Turn off Lane Keep Assist (LKA)
when towing. See Lane Keep Assist
(LKA) 0246.
{Warning
When towing a trailer, exhaust
gases may collect at the rear of the
vehicle and enter if the liftgate,
trunk/hatch, or rear-most window
is open.
When towing a trailer:
. Do not drive with the liftgate,
trunk/hatch, or rear-most
window open.
. Fully open the air outlets on
or under the instrument
panel.

.Also adjust the climate
control system to a setting
that brings in only outside air.
See “Climate Control Systems ”
in the Index.

monoxide, see Engine Exhaust
0 205.
Towing a trailer requires a certain
amount of experience. The
combination you are driving is longer
and not as responsive as the vehicle
itself. Get acquainted with the
handling and braking of the rig before
setting out for the open road.
The structure, tires, and brakes of the
trailer must be rated to carry the load.
Inadequate trailer equipment can
cause the combination to operate in
an unexpected or unsafe manner.
Before starting, check all trailer hitch
parts and attachments, safety chains,
electrical connectors, lamps, tires, and
mirrors. Get familiar with the handling and braking of the rig. If the
trailer has electric brakes, start the
combination moving and then apply
the trailer brake controller by hand to
be sure the brakes work.
During the trip, check occasionally to
be sure that the load is secure and the
lamps and any trailer brakes
still work.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid heavy braking
and sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination will
not accelerate as quickly and is longer
so it is necessary to go much farther
beyond the passed vehicle before
returning to the lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. Tomove the trailer to the right, move
your hand to the right. Always back
up slowly and, if possible, have
someone guide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer will not strike soft
shoulders, curbs, road signs, trees,
or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
If the trailer turn signal bulbs burn
out, the arrows on the instrument
cluster will still flash for turns. It is
important to check occasionally to be
sure the trailer bulbs are still working.

254 DRIVING AND OPERATING
Driving on Grades
Reduce speed and shift to a lower gear
beforestarting down a long or steep
downgrade. If the transmission is not
shifted down, the brakes might get hot
and no longer work well.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing, use the Tow/Haul Mode
to prevent damage to the engine or
transmission. See Tow/Haul Mode
0 210.
When towing at high altitude on steep
uphill grades, consider the following:
Engine coolant will boil at a lower
temperature than at normal altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle may show
signs similar to engine overheating. To
avoid this, let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for a
few minutes before turning the engine
off. If the overheat warning comes on,
see Engine Overheating 0276.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both the
vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park). 5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is
clear of the chocks.
7. Stop and have someone pick up and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service more often
when pulling a trailer. See
Maintenance Schedule 0347. Things
that are especially important in trailer
operation are automatic transmission
fluid, engine oil, axle lubricant, belts,
cooling system, and brake system. It is
a good idea to inspect these before
and during the trip.
Check periodically to see that all hitch
nuts and bolts are tight.

1. Front of Vehicle
2. Body to Ground Distance
When using a weight-distributing
hitch, measure distance (2) before
coupling the trailer to the hitch ball.
Measure the height again after the
trailer is coupled and adjust the spring bars so the distance (2) is as close as
possible to halfway between the two
measurements.
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. Instructions
about safety chains may be provided
by the hitch manufacturer or by the
trailer manufacturer. If the trailer
being towed weighs up to 2 271 kg
(5,000 lb) with a factory-installed step
bumper, safety chains may be
attached to the attaching points on
the bumper, otherwise, safety chains
should be attached to holes on the
trailer hitch platform. Always leave
just enough slack so the combination
can turn. Never allow safety chains to
drag on the ground.Trailer Brakes
A loaded trailer that weighs more than
900 kg (2,000 lb) must be equipped
with its own brake system, with
brakes working on all axles. Trailer
braking equipment conforming to
Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended.
State and local regulations may also
require the trailer to have its own
braking system if loaded above a
certain threshold. These requirements
vary from state to state.

260 DRIVING AND OPERATING
Be sure to read and follow the
instructions for the trailer brakes so
they are installed, adjusted, and
maintained properly.
Do not tap into the vehicle's hydraulic
system.
Since the vehicle is equipped with
StabiliTrak, the trailer brakes cannot
tap into the vehicle's hydraulic
system.
Trailer Wiring Harness
The seven-pin trailer connector is
mounted in the bumper. This
connector can be plugged into a
seven-pin universal heavy-duty trailer
connector available through your
dealer.
Use only a round, seven-wire
connector with flat blade terminals
meeting SAE J2863 specifications for
proper electrical connectivity.
The seven-wire harness contains the
following trailer circuits:
.Yellow/Grey: Left Stop/Turn Signal
. Green/Violet: Right Stop/Turn
Signal .
Grey/Brown: Taillamps
. White: Ground
. White/Green: Back-up Lamps
. Red/Green: Battery Feed
. Dark Blue: Trailer Brake
To help charge a remote (non-vehicle)
battery, press the Tow/Haul Mode
button at the end of the shift lever.
If the trailer is too light for Tow/Haul
Mode, turn on the headlamps to help
charge the battery.Electric Brake Control Wiring
Provisions
These wiring provisions are included
with the vehicle as part of the trailer
wiring package. These provisions are
for an electric brake controller.
The harness should be installed by
your dealer or a qualified service
center.
Trailer Sway Control (TSC)
Vehicles with StabiliTrak have a
Trailer Sway Control (TSC) feature.
Trailer sway is unintended side-to-side
motion of a trailer while being towed. If the vehicle is towing a trailer and
the TSC detects that sway is
increasing, the vehicle brakes are
selectively applied at each wheel, to
help reduce excessive trailer sway.
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak warning
light will flash on the instrument
cluster. Vehicle speed must be
reduced. If trailer sway continues,
StabiliTrak can reduce engine torque
to help slow the vehicle. See
Traction
Control/Electronic Stability Control
0 218.
{Warning
Even if the vehicle is equipped with
TSC, trailer sway could result in
loss of control and the vehicle could
crash. If excessive trailer sway is
detected, slow down to a safe speed.
Check the trailer and vehicle to help
correct possible causes. These could
include an improperly or overloaded
trailer, unrestrained cargo, improper
trailer hitch configuration, excessive

Adding non-dealer accessories can
affect the vehicle performance. See
Accessories and Modifications 0265.
Electronic Trailer Sway Control
Devices
Some trailers may come equipped
with an electronic device designed to
reduce or control trailer sway.
Aftermarket equipment manufacturers
also offer similar devices that connect
to the wiring between the trailer and
the vehicle. These devices may
interfere with the vehicle’s trailer
brake or other systems, including
integrated anti-sway systems,
if equipped. Messages related to trailer
connections or trailer brakes could
appear on the Driver Information
Center (DIC). The effect that these devices may have on vehicle handling
or trailer brake performance is
unknown.
{Warning
Use of electronic trailer sway
control devices could result in
reduced trailer brake performance,
loss of trailer brakes, or other
malfunctions, and could cause a
crash. You or others could be
injured or killed. Before using one
of these devices:
. Ask the device or trailer
manufacturer if the device
has been thoroughly tested
for compatibility with the
make, model, and year of the
vehicle as well as optional
equipment installed on the
vehicle.
