Heated seats (if equipped)
WARNING:Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaustion, or other physical
conditions, must exercise care when using the seat heater. The seat
heater may cause burns even at low temperatures, especially if used
for long periods of time. Do not place anything on the seat that
insulates against heat, such as a blanket or cushion, because this may
cause the seat heater to overheat. Do not puncture the seat with pins,
needles, or other pointed objects because this may damage the heating
element which may cause the seat heater to overheat. An overheated
seat may cause serious personal injury.
Note:Do not do the following:
•Place heavy objects on the seat
•Operate the seat heater if water or any other liquid is spilled on the

Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible 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:
•Class II receiver: 350 lb. (159 kg)
•Class III/IV receiver: 500 lb. (227 kg) (weight carrying); 740 lb.
(336 kg) (weight distributing)

•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 (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 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.
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:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do 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:
•causing internal damage to the components.
•affecting 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
Follow this guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.

•Allows upshifts by moving gearshift lever.
•Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.
Forced downshifts
•Allowed in D (Drive) only.
•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.

ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
For the lubricant specification and refill capacity of the AWD transfer
case refer toMaintenance and Specificationschapter.
WARNING:If your vehicle is equipped with AWD, a spare tire of
a different size than the road tires should never be used. Such a
tire could make the vehicle difficult to control as well as result in
damage to driveline components.
WARNING:Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any
more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Avoid sharp turns or abrupt maneuvers in
these vehicles.
Normal operation (4.0L engine vehicles only)
The AWD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road conditions such as deep snow, ice or shallow
sand.
Normal operation (4.6L engine vehicles only)
During normal operation the AWD system is in AWD AUTO mode (AWD
LOCKED will illuminate in the message center for four seconds when
you first start your vehicle). The 4X4 indicator in the instrument cluster
will also come on.
For instructions on selecting the AWD LOCKED mode, refer toMessage
centerin theDriver Controlschapter. This mode is not intended for use
on dry pavement. This mode is appropriate for severe winter or off-road
conditions such as deep snow, ice or shallow sand. The use of AWD
LOCKED on dry or hard surfaces may produce some noise, such as
occasional clunks, but will not damage the drive system.
Autolock operation (4.6L engine vehicles only)
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
•AWD LOCKED will be displayed in the message center for four
seconds and the 4x4 indicator light will illuminate in the instrument
cluster. A warning chime will also sound. This condition may clear

•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or rollover. Remember, your safety and the
safety of others should be your primary concern.
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles arenotdesigned for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the
LOCK position and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
