•Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Example:
T145/80D18 103M. •
High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

EXAMPLE:
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL)
tire:
•XL = Extra load (or reinforced) tire, or
•LL= Light load tire or
•C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this
tire
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire,
however, the date code may only be on one side. Tires
with white sidewalls will have the full TIN, including the
date code, located on the white sidewall side of the tire. Look for the TIN on the outboard side of black sidewall
tires as mounted on the vehicle. If the TIN is not found on
the outboard side, then you will find it on the inboard
side of the tire.

worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The 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 abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• 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 main-
tenance 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 serious 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 Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for

also increase as the vehicle is driven - this is normal and
there should be no adjustment for this increased pres-
sure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects
and natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring [TPM] Telltale Light) illu-
minates, you must increase the tire pressure to the
recommended cold placard pressure in order for the
“TPM Telltale Light” to turn off. The system will auto-
matically update and the “TPM Telltale Light” will turn
off once the system receives the updated tire pressures.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 information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 23 psi (158 kPa). This tire
pressure is sufficiently low enough to turn ON the “TPM
Telltale Light”. Driving the vehicle may cause the tire
pressure to rise to approximately 27 psi (186 kPa), but the
“TPM Telltale Light” will still be ON. In this situation, the
“TPM Telltale Light” will turn OFF only after the tires are

•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
gauge, even if under-inflation has not reached the level
to trigger illumination of the “TPM Telltale Light”.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System
The Tire Pressure Monitor System (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 monthly
and to maintain the proper pressure. The TPMS consists of the following components:
•
Receiver module,
• Four TPM sensors,
• Various TPMS messages, which display in the Driver
Information Display (DID), and
• TPM Telltale Light

Tire Pressure Monitoring Low Pressure Warnings
The “TPM Telltale Light” will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four active road
tires. In addition, the Drivers Information Display (DID) will display a “LOW TIRE” message and a graphic
showing the pressure values of each tire with the low tire
pressure values shown in a different color.
Should this occur, you should stop as soon as possible
and inflate all of the tires with a low pressure condition
(those shown in a different color in the DID graphic) to
the vehicle’s recommended cold placard pressure infla-
tion value. Once the system receives the updated tire
pressures, the system will automatically update, the
graphic display in the DID will return the pressure values
shown to their original color, and the “TPM Telltale
Light” will turn off. 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 information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.

Service TPMS Warning
If a system fault is detected, the “TPM Telltale Light” will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
DID will display aSERVICE TPM SYSTEM message for
a minimum of five seconds and then display dashes (- -)
in place of the pressure value to indicate which sensor 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 “TPM Telltale Light” will no longer
flash, and the SERVICE TPM SYSTEM message will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors. 2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles With Compact Spare
1. The compact spare tire does not have a TPM 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, the
“TPM Telltale Light” will remain ON and a chime will
sound. In addition, the graphic in the DID will still
display the low pressure values in a different color.

3. After driving the vehicle for up to 10 minutes above15 mph (24 km/h), the “TPM Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the DID will display a SERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
4. For each subsequent ignition switch cycle, a chime will sound, the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the DID
will display a SERVICE TPM SYSTEM message for a
minimum of five seconds and then display dashes (- -)
in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPM Telltale Light” will turn OFF and the graphic in
the DID will display a new pressure value instead of
dashes (- -), 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 information.
