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).
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 Ð 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 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.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.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited Use Spare Ð If Equipped
The limited use spare tire is for temporary emergency use
on your vehicle. This tire is identified by a limited use
spare tire warning label located on the limited use spare
tire and wheel assembly. 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 tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.
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 faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping when you are stuck.
Refer to ªFreeing A Stuck Vehicleº in Section 6 of this
manual for additional information.
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 some-
one. Do not spin your vehicle's wheels faster than 30
mph (48 km/h) or for more than 30 seconds continu-
ously when you are stuck, and don't let anyone near
a spinning wheel, no matter what the speed.

WARNING!
²Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. 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.
²Never 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.
²Failure 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.
Alignment And Balance
Poor suspension alignment may result in:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle 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.
STARTING AND OPERATING 311

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 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 about
1¤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.
²If chains are used on an All Wheel Drive (AWD) vehicle, they
should be used on all four tires.
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 recommended
by the manufacture.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket sealants or balance beads if your
vehicle is equipped with a TPMS, as damage to the
sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the TPMS sensor.
NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stopping
ability.
316 STARTING AND OPERATING
Page 317 of 457

²The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to maintain
correct tire pressure, using an accurate tire pressure
gage, even if under-inflation has not reached the level
to trigger illumination of the TPMS Telltale Lamp.
²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Basic TPMS without EVIC Ð If Equipped
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
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.The Basic TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Lamp
The Tire Pressure Monitoring Telltale Lamp
will illuminate in the instrument cluster and an
audible chime will be activated when one or
more of the four active road tire pressures are
low. Should this occur you should stop as soon as
possible, check the inflation pressure of each tire on your
vehicle, and inflate each tire to the manufacturer recom-
mended pressure, located on the tire pressure placard.
The system will automatically update and the TPMS
warning light will extinguish once the updated tire
pressure(s) have been received.
STARTING AND OPERATING 317

Page 318 of 457

NOTE:The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
The TPMS Telltale Lamp will flash on and off for 75
seconds, and remain on solid when a system fault is
detected. The system fault will also sound a chime. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The TPMS Telltale Lamp
will turn off when the fault condition no longer exists. A
system fault can occur with any of the following sce-
narios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:Your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the TPMS. In the event that the compact spare tire is
swapped with a low pressure road tire, each ignition key
cycle will still show the TPMS Lamp to be ON, and a
chime to sound. Once you repair or replace the original
road tire and reinstall it on the vehicle in place of the
compact spare tire, the TPMS will update automatically,
and the TPMS Lamp will turn OFF as long as no tire
pressure is below the low-pressure warning limit in any
of the four active road tires. The vehicle may need to be
driven for up to 10 minutes above 15 mph (25 km/h) for
the TPMS to receive this information.

Basic TPMS with EVIC Ð If Equipped
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
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.
The Basic TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Various TPMS Messages, which display in the Elec-
tronic Vehicle Information Center (EVIC).
²Tire Pressure Monitoring Telltale LampThe TPMS Telltale Lamp will illuminate in the instru-
ment cluster, and an audible chime will be activated
when one or more of the four active road tire pressures
are low. In addition, EVIC will display the number of
tire(s) that are low, followed by the ªTire Low Pressureº
text message. Should this occur, you should stop as soon
as possible, check the inflation pressure of each tire on
you vehicle, and inflate each tire to the vehicle's recom-
mended cold placard pressure value. The system will
automatically update and the TPMS Lamp will extin-
guish one the updated tire pressures have been received.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (25 km/h) for the TPMS to receive this
information.
The TPMS Telltale Lamp will flash on and off for 75
seconds, and remain on solid when a system fault is
detected. The system fault will also sound a chime. In
addition, EVIC will display a ªSERVICE TIRE SYSTEM
SOONº text message. If the ignition key is cycled, this
STARTING AND OPERATING 319

sequence will repeat, providing the system fault still
exists. The TPMS Telltale Lamp will turn off when the
fault condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:Your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored bythe TPMS. In the event that the compact spare tire is
swapped with a low pressure road tire, each ignition key
cycle will still show the TPMS Lamp to be ON, a chime to
sound, and a ª1 Tire Low Pressureº message to appear in
the EVIC. Once you repair or replace the original road
tire and reinstall it on the vehicle in place of the compact
spare tire, the TPMS will update automatically, and the
TPMS Lamp will turn OFF as long as no tire pressure is
below the low-pressure warning limit in any of the four
active road tires. The vehicle may need to be driven for
up to 10 minutes above 15 mph (25 km/h) for the TPMS
to receive this information.
