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. For vehicles with automatic trans-
mission, push and hold the lock button on
the gear selector. Then, shift back and forth
between DRIVE (D) and REVERSE (R), 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 vehicles with automatic 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 (N) 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
System” in “Safety” in your Owner’s Manual for further details. 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 mini
-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
When “rocking” a stuck vehicle by
shifting between DRIVE/SECOND GEAR
and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drive -
train damage may result.
Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also
damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are oper-
able, disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting And Operating” section.

Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’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 associ -
ated brackets. State and local laws regarding vehi -
cles under tow must be observed.

If you must use the accessories (wipers,
defrosters, etc.) while being towed, the igni -
tion must be in the ON/RUN position, not the
ACC position. If the vehicle's battery is discharged, refer to
“Manual Park Release” in this chapter for
instructions on shifting the automatic trans
-
mission out of PARK in order to move the
vehicle.

Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.Tire Tread
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a 1/16
of an inch (1.6 mm). When the tread is worn
to the tread wear indicators, the tire should
be replaced.
Refer to “Replacement Tires” in this section
for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire
replacement
Distance driven
Performance tires, tires with a speed
rating of V or higher, and Summer tires
typically have a reduced tread life. Rota-
tion of these tires per the vehicle sched -
uled maintenance is highly recommended
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30
seconds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.

(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 exposure 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 manufac-
turer 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 Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
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 original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions 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 combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. 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.
Never use a tire with a smaller load index
or capacity, other than what was origi -
nally equipped on your vehicle. Using a
tire with a smaller load index could result
in tire overloading and failure. You could
lose control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.

Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare
tire and wheel equivalent in look and func-
tion to the original equipment tire and wheel
found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rota -
tion for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for
the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emer -
gency use only. You can identify if your
vehicle is equipped with a compact spare by
looking at the spare tire description on the
Tire and Loading Information Placard
located on the driver’s side door opening or
on the sidewall of the tire. Compact spare
tire descriptions begin with the letter “T” or
“S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the orig -
inal equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity. Do not install a wheel cover or attempt to
mount a conventional tire on the compact
spare wheel, since the wheel is designed
specifically for the compact spare tire. Do
not install more than one compact spare tire
and wheel on the vehicle at any given time.
Full Size Spare — If Equipped
The full size spare is for temporary emer
-
gency use only. This tire may look like the
originally equipped tire on the front or rear
axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the
tread is worn to the tread wear indicators, the
temporary use full size spare tire needs to be
replaced. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by
a label located on the limited use spare
wheel. This label contains the driving limita -
tions for this spare. This tire may look like
the original equipped tire on the front or rear
axle of your vehicle, but it is not. Installation
of this limited use spare tire affects vehicle
handling. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
WARNING!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have
limited tread life. When the tread is worn
to the tread wear indicators, the temporary
use spare tire needs to be replaced. Be
sure to follow the warnings, which apply to
your spare. Failure to do so could result in
spare tire failure and loss of vehicle
control.
