TIRE SAFETY INFORMATION
Tire Markings
NOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter#P#is absent from this tire
size designation. Example: 215/65R15 96H.
•LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.

Tire Repair
If your tire becomes damaged, it may be repaired 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 thana¼ofaninch (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 imme-
diately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (spring,
summer, fall and winter). Traction levels may vary be-
tween different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with summer tires, be
aware these tires are not designed for winter or cold
driving conditions. Install winter tires on your vehicle
when ambient temperatures are less than 40°F (5°C) or if
roads are covered with ice or snow. For more informa-
tion, contact an authorized dealer.

Run Flat Tires — If Equipped
Run 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 immedi-
ately. 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 infor-
mation.
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 automatic car wash with a
compact or limited-use temporary spare installed.
Damage to the vehicle may result.

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. They will appear as bands when the tread depth
becomes a 1/16 of an inch (2 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 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.1—WornTire2—NewTire

Should this occur, you should stop as soon as possible and
inflate the tires with low pressure to the vehicle’s recom-
mended cold placard pressure value. Once the system
receives the updated tire pressures, the system will auto-
matically update and the “Tire Pressure Monitoring Telltale
Light” will turn off. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
sound a chime and also display a “Service Tire Pressure
Monitoring System” message in the EVIC for approxi-
mately 5 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 “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “Service TPM Sys-
tem” 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.
The EVIC will also display a#Service Tire Pressure
Monitoring System#message for a minimum of five
seconds when a system fault related to an incorrect
sensor location fault is detected. In this case, the#Service
Tire Pressure Monitoring System#message is then fol-
lowed with a graphic display with pressure values still

shown. This indicates that the pressure values are still
being received from the TPM sensors but they may not be
located in the correct vehicle position. The system still
needs to be serviced as long as the#Service Tire Pressure
Monitoring System#message is displayed.
NOTE:
•The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
•If you install a replacement tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the “Tire
Pressure Monitoring Telltale Light” will remain on and
a chime will sound. In addition, the highlighted
graphic in the EVIC will still display a pressure value
in a different color.
•After driving the vehicle 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. In addition, the EVIC will
display a “Service Tire Pressure Monitoring System”
message and then display dashes (- -) in place of the
pressure value.
•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, and the EVIC will display a “Service TPM
System” message and dashes (- -) in place of the
pressure value.
