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.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

wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equiva-
lent 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 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
dealer 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.

416 STARTING AND OPERATING

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 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
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 tirepressure 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
inflated to the vehicle’s recommended cold placard pres-
sure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration 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

CAUTION!(Continued)
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your local dealer to have your
sensor function checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.
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
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
5
STARTING AND OPERATING 421

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 DID will display a “LOW TIRE”

2. Installing aftermarket window tinting that containsmaterials 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 DID will also display a SERVICE TPM 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 TPM SYSTEM
message is then followed with a graphic display with
pressure values still shown. This indicates that the pres-
sure 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 TPM SYSTEM message is displayed. 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 and
the Inflate Tire to XX message.
3. After driving the vehicle for up to 20 minutes above 15 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.

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.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
