USING YOUR ALL-WHEEL-DRIVE (AWD) SYSTEM
AWD uses all four wheels to power the vehicle. This increases
traction, enabling you to drive over terrain and road conditions that a
conventional two-wheel drive vehicles cannot. The AWD system is active
all the time and requires no input from the operator.
Note:Your AWD vehicle is not intended for off-road use. The AWD
feature gives your vehicle some limited off-road capabilities in which
driving surfaces are relatively level, obstruction-free and otherwise
similar to normal on-road driving conditions. Operating your vehicle
under other than those conditions could subject the vehicle to excessive
stress which might result in damage which is not covered under your
warranty.
Note:When an AWD system fault is present, the warning Check AWD
will display in the message center. The AWD system is not functioning
correctly and defaulted to front-wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer.
Note:The AWD Off message may also be displayed in the message
center if the AWD system has overheated and defaulted to front-wheel
drive. This condition may occur if the vehicle was operated in extreme
conditions with excessive wheel slip, such as deep sand. To resume
normal AWD function as soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10 minutes. After the engine has
been restarted and the AWD system has adequately cooled, the AWD Off
message will turn off and normal AWD function will return. In the event
the engine is not stopped, the AWD Off message will turn off when the
system cools and normal AWD function returns.
The Power Transfer Unit (PTU) in police vehicles does not require any
normal scheduled maintenance. The system is electronically monitored
and notifies the driver of required service by displaying the message
Change AWD Power Transfer Unit Lube in the information display.
The PTU lube will be more likely to require a fluid change if the vehicle
has experienced extended periods of extreme/severe duty cycle driving.
Do not check or change the PTU lubricant unless the unit has been
submerged in water, shows signs of leakage or a message indicating
required service is displayed. Contact your authorized dealer for service
and to reset the PTU lube life monitor.

If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. The AWD system may
disable automatically and enter front-wheel drive only mode to protect
driveline components if a non-full sized tire is installed. This condition
may be indicated by an AWD Off message in the information display.
If there is an AWD Off message in the message center from using a
non-full sized spare tire, this indicator should turn off after reinstalling
the repaired or replaced normal road tire and cycling the ignition off and
on. It is recommended to reinstall the repaired or replaced road tire as
soon as possible. Major dissimilar tire sizes between the front and rear
axles could cause the AWD system to stop functioning and default to
front-wheel drive or damage the AWD system.
How Utility Vehicles Differ from Other Vehicles (If Equipped)
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside.
Do not grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Driving In Special Conditions With All-Wheel Drive
All-Wheel Drive (AWD) vehicles are equipped for driving on sand, snow,
mud and rough roads and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the highway.
When driving at slow speeds in deep sand under high outside
temperatures, use a low gear when possible. Lower gear operation will
maximize the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.

If your vehicle is equipped with AdvanceTrac® with Roll Stability
Control™, it may be beneficial to disengage the AdvanceTrac® with
Roll Stability Control™ system while attempting to rock the vehicle.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid excessive wheel slip.
Do not drive your vehicle in deep sand for an extended period of time.
This could cause the AWD system to overheat and default to front-wheel
drive. If this occursAW D O f fwill be displayed in the Information
Display.
To resume normal AWD function as soon as possible, stop the vehicle in
a safe location and stop the engine for at least 10 minutes. After the
engine has been restarted and the AWD system has adequately cooled,
theAW D O f fmessage will turn off and normal AWD function will return.
In the event the engine is not stopped, theAW D O f fmessage will turn
off when the system cools and normal AWD function returns.
When driving at slow speeds in deep sand under high outside
temperatures, use L (Low) gear when possible. L (Low) gear operation
will maximize the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.

Driving on snow and ice
WARNING:If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
Note:Excessive tire slippage can cause transmission damage.
AWD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although an AWD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels.
Do not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, apply the brake steadily. Since
your vehicle is equipped with a four wheel anti-lock brake system (ABS),
do not “pump” the brakes. Refer to theBrakessection of this chapter
for additional information on the operation of the anti-lock brake system.

Towing an all-wheel drive vehicle requires that all wheels be off the
ground, such as using a wheel lift and dollies or flatbed equipment. This
prevents damage to the transmission, all-wheel drive system and vehicle.
TOWING THE VEHICLE ON FOUR WHEELS
Emergency Towing
If your vehicle becomes inoperable (without access to wheel dollies,
car-hauling trailer, or flatbed transport vehicle), it can be flat-towed
(all wheels on the ground, regardless of the powertrain and transmission
configuration) under the following conditions:
•Your vehicle is facing forward for towing in a forward direction.
•
Place the transmission in positionN.SeeAutomatic transmissionin
theTransmissionchapter if you cannot move the transmission intoN.
•Maximum speed is 35 mph (56 km/h).
•Maximum distance is 50 miles (80 kilometers).
Recreational Towing
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering your vehicle. See theClimate
Controlchapter.
Follow these guidelines if you have a need for recreational towing, such
as towing your vehicle behind a motorhome or truck. We designed these
guidelines to prevent damage to your vehicle after it is hooked-up to the
recreational vehicle or tow dolly.
You can 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. If you are towing with all four wheels on the ground,
see the following instructions.

You can 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 causes damage to your all-wheel drive system. If you are using a
vehicle transport trailer, follow the instruction specified by the
equipment provider. If you are towing with all four wheels on the ground,
see the following instructions.
If you tow your vehicle with all four wheels on the ground:
•Tow only in the forward direction.
•Release the parking brake.
•Place the transmission in positionN.
•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 every six hours thereafter. With the engine running
and your foot on the brake, shift into positionDand then into
positionRbefore shifting back into positionN.

F.95:Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
owner’s manual. If not, contact a local tire dealer.
Note:You may not find this information on all tires because it is not
required by federal law.
G.H:Indicates the tire’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods of
time under a standard condition of load and inflation pressure. The tires
on your vehicle may operate at different conditions for load and inflation
pressure. These speed ratings may need to be adjusted for the difference
in conditions. The ratings range from 81 mph (130 km/h) to 186 mph
(299 km/h). These ratings are listed in the following chart.
Note:You may not find this information on all tires because it is not
required by federal law.

Note:For tires with a maximum speed capability over 149 mph
(240 km/h), tire manufacturers sometimes use the letters ZR. For
those with a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
H.U.S. DOT Tire Identification Number (TIN):This begins with the
letters DOT and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code designating where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The

Wheel misalignment in the front or the rear can cause uneven and
rapid treadwear of your tires and should be corrected by an authorized
dealer. Front-wheel drive vehicles and those with an independent rear
suspension may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire Rotation
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire and
wheel assembly. A dissimilar spare tire and wheel assembly is defined as
a spare tire or wheel that is different in brand, size or appearance from
the road tires and wheels. If you have a dissimilar spare tire and wheel
assembly, it is intended for temporary use only and should not be used
in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
Rotating your tires at the recommended interval (as indicated in the
scheduled maintenance information) will help your tires wear more
evenly, providing better tire performance and longer tire life.
