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 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 original equip-
ment 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.
WARNING!
Compact 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.
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
520 STARTING AND OPERATING

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
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
your original 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. In-
stallation 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 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 stop-
ping when you are stuck.
Refer to “Freeing A Stuck Vehicle” in “What To Do In
Emergencies” for further 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) for more than 30 seconds continu-
ously when you are stuck, and do not 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.

Information placard or the Vehicle Certification 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 ex-
ample 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 you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire or
original equipment dealer with any questions you may
have on tire specifications 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 or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion 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 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.

524 STARTING AND OPERATING

For example, your vehicle may have a recommended
cold (parked for more than three hours) tire placard
pressure of 35 psi (241 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 30 psi (207
kPa), a temperature drop to 20°F (-7°C) will decrease the
tire pressure to approximately 26 psi (179 kPa). This tire
pressure is sufficiently low enough to turn on the “Tire
Pressure Monitoring Telltale Light.” Driving the vehicle
may cause the tire pressure to rise to approximately 30
psi (207 kPa), but the “Tire Pressure Monitoring Telltale
Light” will still be on. In this situation, the “Tire Pressure
Monitoring Telltale Light” will turn off only after the tires
have been inflated to the vehicle’s recommended cold tire
placard pressure value.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.
• 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.
5
STARTING AND OPERATING 529

NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide 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 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 “Tire Pressure Monitor-
ing Telltale Light.” •
Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
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 to maintain
the proper pressure.
The Basic TPMS consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• TPMS Telltale Warning Light
530 STARTING AND OPERATING

3. Accumulation of excessive snow and/or ice aroundthe wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
1. The compact spare tire (if equipped) does not have a TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, a chime
will sound, a “LOW TIRE PRESSURE” message will
be displayed and the “Tire Pressure Monitoring Tell-
tale Light” will turn on. 3. After driving for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale
Light” will flash on and off for 75 seconds and then
remain on solid.
4. For each subsequent ignition switch cycle, a chime will sound, the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
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 automatically update, and the “Tire
Pressure Monitoring 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.
NOTE: The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) for the TPMS to receive
this information.
532 STARTING AND OPERATING

Premium System – 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 to regularly check
and maintain proper tire pressure in all the tires.
The Premium TPMS consists of the following compo-
nents:
• Receiver Module
• Four TPMS Sensors
• Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and graphics
displaying tire pressures
• TPMS Telltale Warning Light
TPMS Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. In addition, the EVIC will display a
“LOW TIRE” message and a graphic display of the
pressure value(s) with the low tire(s) flashing. An Inflate
Tire to XX message will also be displayed.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold tire pressure
value as shown in the Inflate Tire to XXmessage. The
system will automatically update, the graphic display of
the pressure value(s) will stop flashing, and the “Tire
Pressure Monitoring Telltale Light” will extinguish once
the updated tire pressure(s) have been received.

NOTE:The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” 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. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This text
message is then followed by a graphic display, with --in
place of the pressure value(s) indicating which TPMS
Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, the “SERVICE TPM SYSTEM” message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
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.
The EVIC will also display a “SERVICE TPM SYSTEM”
message for a minimum of five seconds when a system
fault possibly related to an incorrect sensor location fault
is present. In this case, the “SERVICE TPM SYSTEM”

The label contains the following information:
•Name of manufacturer
• Month and year of manufacture
• Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
• Type of Vehicle
• Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels 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 a collision.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
