IN CASE OF EMERGENCY 405
(Continued)FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front wheels.
Then shift back and forth between DRIVE and REVERSE,
while gently pressing the accelerator. Use the least amount of
accelerator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the engine.
NOTE:
• For trucks equipped with an 8–speed transmission, shifts
between DRIVE and REVERSE can only be achieved at
wheel speeds of 5 mph (8 km/h) or less. Whenever the
transmission remains in NEUTRAL for more than two
seconds, you must press the brake pedal to engage DRIVE
or REVERSE.
• Push the "ESC Off" switch, to place the Electronic Stability
Control (ESC) system in "Partial Off" mode, before rocking
the vehicle. Refer to “Electronic Brake Control” in “Safety”
for further information. Once the vehicle has been freed,
push the "ESC Off" switch again to restore "ESC On" mode. WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck and
do not let anyone near a spinning wheel, no matter what
the speed.
CAUTION!
• Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the engine
to idle with the transmission in NEUTRAL for at least
one minute after every five rocking-motion cycles. This
will minimize overheating and reduce the risk of trans -
mission failure during prolonged efforts to free a stuck
vehicle.
• When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result. 6
IN CASE OF EMERGENCY 407
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip -
ment designed for this purpose, following equipment manu -
facturer’s instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main structural
members of the vehicle, not to bumpers or associated
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable or the vehicle's battery is
discharged, refer to “Manual Park Release” or “Gear Selector
Override” in this section for instructions on shifting the auto -
matic transmission out of PARK for towing. Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the transmission is
operable, the vehicle may be towed (with the rear wheels on
the ground) under the following conditions:
• The transmission must be in NEUTRAL. Refer to “Manual
Park Release” in this section for instructions on shifting the
8–speed transmission to NEUTRAL when the engine is off.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 15 miles (24 km) for
6–speed transmission, or 30 miles (48 km) for 8–speed
transmission.
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 15 miles
(24 km) for 6–speed transmission, or 30 miles (48 km) for
8–speed transmission, tow with the rear wheels OFF the
ground. Acceptable methods are to tow the vehicle on a
flatbed, or with the front wheels raised and the rear wheels
on a towing dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight position)
with rear wheels raised and the front wheels on the ground.CAUTION!
• Do not use sling type equipment when towing. Vehicle
damage may occur.
• When securing the vehicle to a flat bed truck, do not
attach to front or rear suspension components. Damage
to your vehicle may result from improper towing. 6

(Continued)Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and satis -
factory operation of your vehicle. Four primary areas are
affected by improper tire pressure:
• Safety
• Fuel Economy
• Tread Wear
• Ride Comfort and Vehicle Stability
Safety
Both under-inflation and over-inflation affect the stability of
the vehicle and can produce a feeling of sluggish response or
over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause erratic
and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.WARNING!
• Improperly inflated tires are dangerous and can cause
collisions.
• Underinflation increases tire flexing and can result in
overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause damage
that result in tire failure. • Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle to
the other can cause the vehicle to drift to the right or
left.
• Always drive with each tire inflated to the recom -
mended cold tire inflation pressure. WARNING! (Continued)
SERVICING AND MAINTENANCE 459
(Continued)NOTE:
Wheel Valve Stem must be replaced as well when installing
new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little expo -
sure to light as possible. Protect tires from contact with oil,
grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for wear
and correct cold tire inflation pressures. The manufacturer
strongly recommends that you use tires equivalent to the
originals in size, quality and performance when replacement
is needed. Refer to the paragraph on “Tread Wear Indica -
tors” in this section. Refer to the Tire and Loading Informa -
tion placard or the Vehicle Certification Label for the size
designation of your tire. The Load Index and Speed Symbol
for your tire will be found on the original equipment tire
sidewall.
See the Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more information
relating to the Load Index and Speed Symbol of a tire. It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the orig -
inal wheels.
It is recommended you contact an authorized tire dealer or
original equipment dealer with any questions you may have
on tire specifications or capability. Failure to use equivalent
replacement tires may adversely affect the safety, handling,
and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating, or speed rating
other than that specified for your vehicle. Some combi -
nations of unapproved tires and wheels may change
suspension dimensions and performance characteris -
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredictable
handling and stress to steering and suspension compo -
nents. You could lose control and have a collision
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle. 7
466 SERVICING AND MAINTENANCE
(Continued)Tire Rotation Recommendations
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving, and
braking functions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres -
sive tread designs such as those on On/Off Road type tires.
Rotation will increase tread life, help to maintain mud, snow,
and wet traction levels, and contribute to a smooth, quiet
ride.WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance between
tires and other suspension components, it is important
that only traction devices in good condition are used.
Broken devices can cause serious damage. Stop the
vehicle immediately if noise occurs that could indicate
device breakage. Remove the damaged parts of the
device before further use.
• Install device as tightly as possible and then retighten
after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for a prolonged period on dry pavement. • Observe the traction device manufacturer’s instruc -
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested oper -
ating speed of the device manufacturer’s if it is less
than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire. CAUTION! (Continued)
