Radial-Ply Tires
WARNING!Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or 6, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs. Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
WARNING!Temporary use spare tires are for emergency use
only. With these tires, do not drive more than 50 mph
(80 km/h). Temporary-use spare tires have limited
tread life. When two or more tread wear indicators
appear in adjacent grooves, 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.320 STARTING AND OPERATING

WARNING!The limited use spare tires are for emergency use
only. Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold
tire inflation pressure listed on either your tire
placard or limited use spare tire and wheel assembly.
Replace (or repair) the original tire at the first
opportunity and reinstall it on your vehicle. Failure
to do so could result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle ’ s wheels above 35 mph (55 km/h).
See the paragraph on Freeing A Stuck Vehicle in Section
6 of this manual. WARNING!Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle ’ s wheels faster
than 35 mph (55 km/h) when you are stuck. And
don ’ t let anyone near a spinning wheel, no matter
what the speed.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.322 STARTING AND OPERATING

These indicators are molded into the bottom of the tread
grooves and will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the indicators appear
in 2 or more adjacent grooves, the tire should be replaced.
Many states have laws requiring tire replacement at this
point. 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 pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability. STARTING AND OPERATING 323

WARNING!• Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
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 originally 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 an accident.
• 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 read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
• Fast tire wear.
• Uneven tire wear, such as feathering and one-sided
wear.
• Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.324 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE PRESSURE MONITOR SYSTEM — IF
EQUIPPED
The Tire Pressure Monitor System (TPM) system uses
wireless technology with wheel rim mounted electronic
sensors to monitor tire pressure levels (EXCLUDING
THE SPARE TIRE). Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure readings to
a receiver located in the instrument panel.
NOTE: The tire pressure monitoring system on your
vehicle will warn you when one of your tires is signifi-
cantly underinflated and when some combinations of
your tires are significantly underinflated. It is particularly
important, therefore, for you to check the tire pressure in
all of your tires regularly and maintain proper pressure. 1,2,3, OR 4 TIRE(S) LOW PRESSURE
Low tire pressure levels of 28 psi [1.9 bars] (193 kPa) or
less detected in one or more tires.
Inspect all tires for proper inflation pressure, once proper
tire pressure has been set the TPM system warning will
reset automatically once ignition switch has been turned
ON.
1,2,3, OR 4 TIRE(S) HIGH PRESSURE
High tire pressure levels of 48 psi [3.3 bars] (330 kPa) or
more detected in one or more tires.
Inspect all tires for proper inflation pressure, once proper
tire pressure has been set the TPM system warning will
reset automatically once ignition switch has been turned
ON. STARTING AND OPERATING 325

CHECK TPM SYSTEM
The Tire Pressure Monitor System (TPM) system requires
service.
See your authorized dealer for service.
CAUTION!The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant or balance beads if your vehicle
is equipped with TPM system as damage to the
sensors may result. NOTE:
• The TPM system can inform the driver of a low tire
pressure condition of 28 psi [1.9 bars] (193 kPa) or less,
or high a tire pressure condition of 48 psi [3.3 bars]
(330 kPa) or more.
• The TPM system is not intended to replace normal tire
care and maintenance, nor to provide warning of a tire
failure or condition.
• The TPM system should not be used as a tire pressure
gauge while adjusting your tire pressure.
CAUTION!After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt entry into the valve stem, which
could damage the wheel rim sensor.326 STARTING AND OPERATING

CAUTION!To avoid damage to your vehicle or tires, observe the following
precautions:
• Because of restricted chain clearance between tires and other sus-
pension components, it is important that only chains in good
condition are used. Broken chains can cause serious damage. Stop
the vehicle immediately if noise occurs that could indicate chain
breakage. Remove the damaged parts of the chain before further
use.
• Install chains on the front wheels as tightly as possible and then
retighten after driving about 1
⁄ 2
mile (0.8 km).
• Do not exceed 45 mph (70 km/h).
• Drive cautiously and avoid severe turns and large bumps, especially
with a loaded vehicle.
• Do not use on rear wheels of All Wheel Drive (AWD) vehicles.
• Do not drive for prolonged period on dry pavement.
• Observe the tire chain manufacturer ’ s instructions on the method of
installation, operating speed, and conditions for use. Always use the
lower suggested operating speed of the chain manufacturer if
different than the speed recommended by the manufacture. NOTE: In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer ’ s
instructions on method of installation, operating speed,
and conditions for usage.
Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.328 STARTING AND OPERATING

SNOW TIRES
Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire side wall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph (120
km/h). 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, and tend to develop irregular wear pat-
terns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.
Follow the recommended tire rotation frequency for your
type of driving found in the “ Maintenance Schedules ”
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed. STARTING AND OPERATING 329

WARNING!Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR. Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle ’ s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate. STARTING AND OPERATING 337

WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph. JACKING AND TIRE CHANGING
WARNING!• Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.
• For vehicles equipped with fold-in-floor seating, if it
is necessary to retrieve the spare tire from under the
vehicle on the side of the vehicle close to moving
traffic. Pull far enough off the road to avoid the
danger of being hit.346 WHAT TO DO IN EMERGENCIES
