Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.

Hitches
Do not use hitches that clamp onto the vehicle’s bumper or attach to the
axle. You must distribute the load in your trailer so that 10%–15% of the
total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer’s safety chains to the hook retainers on the
hitch. To connect the trailer’s safety chains, cross the chains under the
trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Be sure your trailer conforms to all applicable local and Federal
Regulations regarding trailer braking. If your trailer is equipped with
electronically controlled brakes you will need to have an electronic brake
controller with associated wiring installed to your vehicle by an
authorized dealer.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Do not splice into the vehicle lamp wiring for trailer lamps. Your
vehicle uses an advanced electronic module to control and
monitor your vehicle lamps. Splicing into the wiring or attaching
wiring to the vehicle bulb. may DISABLE the rear vehicle lamps
or cause them not to function properly. Your lamp outage feature
may also be disabled or provide incorrect information.
See your authorized dealer or trailer rental agency for proper
instructions and equipment for hooking up trailer lamps.

Driving while you tow
When towing a trailer:
•To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1600 km) of a new vehicle.
•To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph (112
km/h) with no full throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Understanding the positions of the 6–speed automatic
transmissionsection in this chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance Guide
for more information.

Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle for personal travel (such as behind a motor home or a
truck).
In case of roadside emergency with a disabled vehicle, please refer to
Wrecker towingin theRoadside Emergencieschapter.
These guidelines are designed to prevent damage to your vehicle.
Front Wheel Drive (FWD) vehicles:
Tow your Front Wheel Drive vehicle with all four wheels on the ground
or with the front wheels off the ground by using a tow dolly. If you are
using a tow dolly follow the instructions specified by the equipment
provider.

All Wheel Drive (AWD) vehicles:
Tow your All Wheel Drive vehicle with all four wheels on the ground or
with all four wheels off the ground using a vehicle transport trailer.Do
not tow your All Wheel Drive vehicle with the front wheels off
the ground (by using a tow dolly) and the rear wheels on the
ground.This will cause damage to your AWD system. If you are using a
vehicle transport trailer, follow the instruction specified by the
equipment provider.
Note:If you tow your vehicle with all four wheels on the ground, follow
these instructions:
•Tow only in the forward direction
•Release the parking brake
•Place the transmission shift lever in Neutral (N)
•Turn the key in the ignition to the ACC position (refer toStartingin
theDrivingchapter). The ACC position also unlocks the steering
wheel.
•Do not exceed 65 mph (105 km/h)
•Start the engine and allow it to run for five minutes at the beginning
of each day and at each fuel stop.

Push the parking brake pedal
downward again to release the
parking brake. Driving with the
parking brake on will cause the
brakes to wear out quickly and
reduce fuel economy.
Note:If the vehicle is driven with
the parking brake applied, a chime
will sound.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTrac
with RSC system provides stability enhancement
features such as Roll Stability Control™ (RSC), Electronic Stability
Control (ESC) and Traction Control (TCS) for certain driving situations.
The system includes an AdvanceTrac
with RSC on/off button, and a
“sliding car” icon in the instrument cluster.
The Anti-lock Braking System (ABS) will work with the regular brakes in
order to prevent wheel lock during a braking event. This feature will also
help provide better steerability during braking.
During AdvanceTrac
with RSC operation you may experience the following:
•A rumble, grunting, or grinding noise after startup and when driving
off
•A slight deceleration of the vehicle
•The AdvanceTrac
with RSC indicator light will flash when the system
is activated.
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
Traction Control
Traction Control helps your vehicle maintain traction, when driving on
slippery and/or hilly road surfaces, by detecting and controlling wheel
spin. Excessive wheel spin is controlled by momentarily reducing engine
power and/or applying the anti-lock brakes.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac
with RSC system off by pressing the AdvanceTrac

with RSC button momentarily. This will allow your wheels to spin and
your tires to “dig” for traction. If your vehicle seems to lose engine
power while driving in deep sand or very deep snow, switching off the
AdvanceTrac with RSC stability enhancement feature will restore full
engine power and torque to each wheel.

If the AdvanceTrac
with RSC system is activated excessively in a short
period of time, the brake portion of the system will disable to allow the
brakes to cool down. In this situation, Traction Control will use only
engine power reduction to help control the wheels from over-spinning.
When the brakes have cooled down, the system will again function
normally. Anti-lock braking, RSC and ESC are not affected by this
condition and will function normally during the cool-down period.
During Traction Control events the “sliding car” icon in the instrument
cluster will flash momentarily.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) with RSC system may enhance
your vehicle’s stability during adverse maneuvers.
The AdvanceTrac
with RSC system helps the driver maintain steering
control. AdvanceTrac
with RSC will attempt to correct the vehicle
motion by applying brake force at individual tires and, if necessary, by
reducing engine power.
During Electronic Stability Control events the “sliding car” icon in the
instrument cluster will flash momentarily.
Driving maneuvers which may activate AdvanceTrac
with RSC system
include:
•Taking a turn too fast.
•Maneuvering quickly to avoid an accident, pedestrian or obstacle.
•Driving over a patch of ice.
•Changing lanes on a snow-rutted road.
•Entering a snow-free road from a snow-covered side street, or vice
versa.
•Entering a paved road from a gravel road, or vice versa.
•Driving on slick surfaces.
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter.)
Roll Stability Control™ (RSC)
The RSC system works in conjunction with the AdvanceTrac
system to
help maintain roll stability of the vehicle during aggressive maneuvers by
applying brake force to one or more wheels.
During Roll Stability Control™ (RSC) events the “sliding car” icon in the
instrument cluster will flash momentarily.

Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a AdvanceTrac
with
RSC event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
If a failure is detected in the AdvanceTrac
with RSC system, and the
AdvanceTrac
with RSC button has not been pushed, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced by an authorized dealer immediately.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If the noise is excessive, check
for a low power steering fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by a low power
steering fluid level. Check for a low power steering fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering fluid reservoir above the MAX mark on
the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
