Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire's load carrying capacity if you
adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR's) for the front and rear
axles must not be exceeded. For further information on
GAWR's, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual.To determine the maximum loading conditions of your
vehicle, locate the statement ªThe combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of occu-
pants and cargo should never exceed XXX poundsº on
your vehicle's placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.

WARNING!
Overloading of your tire is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle-never
overload them.
TIRESÐGENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. SafetyÐ
WARNING!
Improperly inflated tires are dangerous and can cause
accidents.
²Under inflation increases tire flexing and can result in
tire failure.
²Over inflation reduces a tire's ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
²Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
²Over inflated or under inflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
²Unequal 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.
222 STARTING AND OPERATING

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on either the face of the driver's door or the
driver's side ªBº pillar. For vehicles other than passenger
cars, the cold tire inflation pressures are listed on either
the ªBº pillar, the Certification Label or in the Tire
Inflation Pressures brochure in the glove compartment.Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less that the maxi-
mum loaded vehicle condition. These pressure condi-
tions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
ªBº PILLAR
STARTING AND OPERATING 223

The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap±if equipped. This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
ªcold tire inflation pressureº. Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least 3 hours, or driven less than 1mile(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire side wall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12É F (7É C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage especially in
the winter.
Example: If garage temperature = 68É F (20É C) and the
outside temperature = 32É F (0É C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12É F (7É C) for this
outside temperature condition.
224 STARTING AND OPERATING

Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don't drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).

Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
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.
228 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.
ALL WHEEL DRIVE (AWD) Ð IF EQUIPPED
CAUTION!
All Wheel Drive (AWD) vehicles must have the same
size and type tires on all wheel positions. Unequal
tire sizes must not be used. Unequal tire size may
cause failure of the power transfer unit and/or the
viscous coupling.
TIRE PRESSURE MONITOR SYSTEM Ð 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
the Electronic Vehicle Information Center (EVIC) display
in the instrument cluster.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and too main-
tain the proper pressure.
When the appropriate conditions exist, the Electronic
Vehicle Information Center (EVIC) displays the following
messages.
230 STARTING AND OPERATING

1,2,3, OR 4 TIRE(S) LOW PRESSURE
Low tire pressure levels of 25 psi [1.72 bars] (172 kPa) or
less detected in one or more tires.

OWNER'S MANUAL
The Tire Pressure Monitor System (TPM) system requires
service.
See your authorized dealer for service.
TIRE PRESSURE UNAVAILABLE
The TPM system function is temporarily unavailable due
to external electromagnetic interference, such as portable
electronic devices, or near by radio or TV towers.
Move the vehicle to an area free from radio, TV antennas
and transmitting towers or disconnect any portable elec-
tronic devices. Once the external interference is removed
the TPM system will resume normal operation and ªTIRE
PRESSURE NOW AVAILABLEº will appear in the Elec-
tronic Vehicle Information Center (EVIC) display.

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 system operation or sen-
sor damage 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 a TPM system, as damage
to the sensors may result.
NOTE:
²The TPM system can inform the driver of a low tire
pressure condition of 25 psi [1.72 bars] (172 kPa) or
less, or high a tire pressure condition of 45 psi [3.10
bars] (310 kPa) or more.
²The TPM system is not intended to replace normal tire
care and maintenance, nor to provide warning of a tire
failure or condition.
²The TPM system should not be used as a tire pressure
gauge while adjusting your tire pressure.
²The TPM system must be retrained after a tire rotation
or wheel rim mounted sensor replacement. See your
authorized dealer for service.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap, if equipped. This
will prevent moisture and dirt from entering the
valve stem, which could damage the wheel rim
sensor.

TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type ªClass Sº specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer.
NOTE:Do not use tire chains on a compact spare tire.
CAUTION!
To avoid damage to your vehicle or tires, observe the following
precautions:
²Because of restricted chain clearance between tires and
other suspension 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.
²Install chains on the front wheels as tightly as possible and
then retighten after driving about1¤2mile (0.8 km).
²Do not exceed 45 mph (70 km/h).
²Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
²Do not use on rear wheels of All Wheel Drive (AWD)
vehicles.
²Do not drive for prolonged period on dry pavement.
²Observe 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 recom-
mended by the manufacture.
