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 bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10±15% of the total weight of the trailer is on the tongue, not to exceed
the maximum tongue loads as stated:
²Class II receiver: 350 lb. (159 kg)

Safety chains
Always connect the trailer's safety chains to the frame or hook retainers
of the vehicle 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.
Class III Trailer Hitch Safety Chain
Loops can be used as recovery
hooks.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer's
specifications. The trailer brakes must meet local and Federal
regulations.
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. See your
authorized dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.

Never connect any trailer lighting to the vehicle's taillamp
circuits, because it may damage the electrical system resulting in
fire. Contact your authorized dealer for assistance in proper trailer tow
wiring installation. Additional electrical equipment may be required.
Driving while you tow
When towing a trailer:
²Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don't make full throttle
starts.
²Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with an automatic transmissionsection in theDriving
chapter.)
²Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument Cluster
chapter.
²Anticipate stops and brake gradually.
²Do 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
Informationfor more information.
Trailer towing tips
²Practice 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.
²Allow more distance for stopping with a trailer attached.
²If 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.

²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
²If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, 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 500 miles (800 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.
²After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
²do not allow the static water level to rise above the bottom edge of
the rear bumper.
²do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
²causing internal damage to the components.
²affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.

If the vehicle is stuck in snow or mud or when driving in deep sand,
switching off the AdvanceTrac with RSC system may be beneficial so the
wheels are allowed to spin. 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 will enhance momentum through the obstacle.
During Traction Control events the9sliding car9icon 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 AdvanceTractwith RSC system helps the driver maintain steering
control. AdvanceTractwith 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 the9sliding car9icon in the
instrument cluster will flash momentarily.
Driving maneuvers which may activate AdvanceTractwith RSC system
include:
²Taking a turn too fast.
²Maneuvering quickly to avoid an accident, pedestrian or obstacle.
²Driving over a patch of ice.
²Changing lanes on a snow-rutted road.
²Entering a snow-free road from a snow-covered side street, or vice
versa.
²Entering a paved road from a gravel road, or vice versa.
²Driving on slick surfaces.
²Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter.)
Roll Stability Controly(RSC)
The RSC system works in conjunction with the AdvanceTractsystem to
help maintain roll stability of the vehicle during aggressive maneuvers by
applying brake force to one or more wheels.
During Roll Stability Controly(RSC) events the9sliding car9icon in the
instrument cluster will flash momentarily.

Certain add-on devices such as large trailer hitches, bike or
surfboard racks and any device that may block the normal
detection zone of the RSS system may create false beeps.
The RSS detects obstacles up to six
feet (two meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
The RSS automatically turns on when the gear selector is placed in R
(Reverse) and the ignition is ON. A control in the message center allows
the driver to disable the system only when the ignition is ON and the
gear selector is in R (Reverse). Refer toMessage centerin theDriver
Controlschapter for more information.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
