WARNING!(Continued)
•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 af-
fect 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
recommended cold tire inflation pressure.
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.
Fuel Economy
Underinflated tires will increase tire rolling resis-
tance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Over-inflation produces a jarring and un-
comfortable ride.
Tire Inflation PressuresThe proper cold tire inflation pressure is listed
on the driver’s side B-Pillar or rear edge of the
driver’s side door.At least once a month:
•Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly in-
flated even when they are under-inflated.
•Inspect tires for signs of tire wear or visible
damage.
CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from en-
tering the valve stem, which could damage
the valve stem.
Inflation pressures specified on the placard are
always “cold tire inflation pressure”. Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km)
after sitting for a minimum of three hours. The
196

cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire
sidewall.
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 12°F (7°C) of air temperature change.
Keep this in mind when checking tire pressure
inside a garage, especially in the Winter.
Example: If garage temperature = 68°F (20°C)
and the outside temperature = 32°F (0°C) then
the cold tire inflation pressure should be in-
creased by 3 psi (21 kPa), which equals 1 psi (7
kPa) for every 12°F (7°C) for this outside tem-
perature condition.
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 pres-
sure will be too low.Tire Pressures For High Speed
Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits. Where
speed limits or conditions are such that the
vehicle can be driven at high speeds, maintain-
ing correct tire inflation pressure is very impor-
tant. Increased tire pressure and reduced ve-
hicle loading may be required for high-speed
vehicle operation. Refer to your authorized tire
dealer or original equipment vehicle dealer for
recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum ca-
pacity 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
a collision. Always use radial ply tires in sets
of four. Never combine them with other types
of tires.
Tire Repair
If your tire becomes damaged, it may be re-
paired if it meets the following criteria:
•The tire has not been driven on when flat.
•The damage is only on the tread section of
your tire (sidewall damage is not repairable).
•The puncture is no greater thana¼ofan
inch (6 mm).
Consult an authorized tire dealer for tire repairs
and additional information.
Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat tire
197

Run Flat Tires — If EquippedRun Flat tires allow you the capability to drive 50
miles (80 km) at 50 mph (80 km/h) after a rapid
loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable.
It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “What To Do In Emergencies”
for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-
matic car wash with a compact or limited-use
temporary spare installed. Damage to the
vehicle may result.
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 function 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 rotation 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 emergency
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 Load-
ing Information Placard located on the driver’s
side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with theletter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first op-
portunity.
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.
WARNING!
Compact spares are for temporary emer-
gency use only. With these spares, do not
drive more than 50 mph (80 km/h). Tempo-
rary 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,
(Continued)

WARNING!(Continued)
which apply to your spare. Failure to do so
could result in spare tire failure and loss of
vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency
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 EquippedThe limited use spare tire is for temporary emer-
gency use only. This tire is identified by a label
located on the limited use spare wheel. This label
contains the driving limitations 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 youroriginal equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare tire
affects vehicle handling. With this tire, do not
drive more than the speed listed on the limit
use spare wheel. Keep inflated to the cold
tire inflation pressures listed on your Tire and
Loading Information Placard located on the
driver’s side B-Pillar or the rear edge of the
driver’s side door. Replace (or repair) the
original equipment tire at the first opportunity
and reinstall it on your vehicle. Failure to do
so could result in loss of vehicle control.
Tire SpinningWhen stuck in mud, sand, snow, or ice condi-
tions, 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 “What To
Do In Emergencies” for further information.
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.
Tread Wear IndicatorsTread wear indicators are in the original equip-
ment tires to help you in determining when your
tires should be replaced.
200

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 TireThe 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 ab-
normal 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. Rotation of these tires
per the vehicle maintenance schedule is
highly recommended.
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 seri-
ous injury or death.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 TiresThe tires on your new vehicle provide a balance
of many characteristics. They should be in-
spected 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 Indicator”. Refer to the Tire and
Loading Information placard or the Vehicle Cer-
tification 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
Tire Tread

you ever replace a wheel, make sure that the
wheel’s specifications match those of the origi-
nal wheels.
It is recommended you contact your authorized
tire dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replace-
ment tires may adversely affect the safety,
handling, and ride of your vehicle.
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 suspension dimen-
sions and performance characteristics, re-
sulting 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
(Continued)
WARNING!(Continued)
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 a collision.
•Failure to equip your vehicle with tires
having adequate speed capability can re-
sult in sudden tire failure and loss of ve-
hicle control.
CAUTION!
Replacing original tires with tires of a differ-
ent size may result in false speedometer and
odometer readings.
TIRE CHAINS (TRACTION
DEVICES)
Use of traction devices require sufficient tire-to-
body clearance. Follow these recommenda-
tions to guard against damage.
•Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
•Install on Front Tires.
•A 215/60R17 96H tire with the use of a
traction device that meets the SAE type
"Class S"specification is recommended.
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!
•The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures and warning have been estab-
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage.
•Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to an authorized dealership to have your
sensor function checked.
•After inspecting or adjusting the tire pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the TPMS sensor.NOTE:
•The TPMS is not intended to replace nor-
mal tire care and maintenance or to pro-
vide warning of a tire failure or condition.
•The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
•Driving 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.
•The TPMS is not a substitute for proper
tire maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure using an accurate tire gauge,
even if under-inflation has not reached
the level to trigger illumination of the Tire
Pressure Monitoring Telltale Light.
•Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.Base System
This is the TPMS warning indicator
located in the instrument cluster.
The TPMS uses wireless technology with wheel
rim mounted electronic sensors to monitor tire
pressure levels. 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 the tires on your
vehicle regularly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
•Receiver Module.
•Four Tire Pressure Monitoring Sensors.
•Tire Pressure Monitoring Telltale Light.
205

5. 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 Tire Pressure Monitor-
ing Telltale Light 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 (24 km/h) in
order for the TPMS to receive this informa-
tion.
Premium System — If EquippedThe TPMS uses wireless technology with wheel
rim mounted electronic sensors to monitor tire
pressure levels. 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 to maintain the proper pressure.
The TPMS consists of the following compo-
nents:•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Three Trigger Modules (mounted in three of
the four wheel wells)
•Various Tire Pressure Monitoring System
Messages, which display in the Electronic
Vehicle Information Center (EVIC)
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an au-
dible chime will be activated when one or more
of the four active road tire pressures are low.
The audible chime will sound once every igni-
tion cycle for the first condition that it detects. In
addition, the EVIC will display a “LOW TIRE”
text message for a minimum of five seconds
and a graphic of the pressure value(s) with the
low tire(s) flashing.Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible and inflate all tires that are flashing
on the graphic display to the vehicle’s recom-
mended cold placard pressure value. The sys-
tem will automatically update, the “LOW TIRE”
text message will no longer be displayed, the
graphic display of the pressure value(s) will stop
flashing, and the Tire Pressure Monitoring Light
will extinguish once the updated tire pressure(s)
have been received.
