Tire Pressure Monitoring Low Pressure Warning

Should this occur, you should stop as soon as
possible and inflate the tires with low pres -
sure (those in a different color in the instru -
ment cluster graphic) to the vehicle’s
recommended cold placard pressure value.
Once the system receives the updated tire
pressures, the system will automatically
update, the pressure values in the graphic
display in the instrument cluster will return to
their original color, and the “Tire Pressure
Monitoring Warning 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
5 psi (35 kPa) above the recommended cold
placard pressure in order to turn the Tire
Pressure Monitoring Warning Light off.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Warning 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 instrument
cluster will display a "SERVICE 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 key is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists,
the “Tire Pressure Monitoring Warning
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:
Jamming due to electronic devices or
driving next to facilities emitting the same
radio frequencies as the TPMS sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Lots of snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
Vehicles With Compact Spare or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the
compact spare tire.

Tire Chains And Traction Devices
Use of traction devices require sufficient
tire-to-body clearance. Follow these recom-
mendations to guard against damage.
Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer
Use on front tires only
Due to limited clearance, the following
traction devices are recommended: Front Wheel Drive (FWD) Models
Original equipment 225/60R17 and 225/
55R18 tire sizes are not chainable.
Snow chains are permitted with the use of
215/60R17 tires on size 17 x 7.0 ET41
wheels.
Use reduced size snow chains with a
maximum projection of 7 mm beyond the
tire profile.
Four Wheel Drive (4WD) Non-Trailhawk Models
without a Two-Speed Power Transfer Unit
Original equipment 225/60R17 and 225/
55R18 tire sizes are not chainable.
Snow chains are permitted with the use of
215/60R17 tires on size 17 x 7.0 ET41
wheels.
Use reduced size snow chains with a
maximum projection of 9 mm beyond the
tire profile. Four Wheel Drive (4WD) Non-Trailhawk Models
with a Two-Speed Power Transfer Unit
Snow chains are permitted with 225/
60R17 and 225/55R18 tires.
Use reduced size snow chains with a
maximum projection of 7 mm beyond the
tire profile.
Four Wheel Drive (4WD) Trailhawk Models
Original equipment 245/65R17 and
P245/65R17 sizes are not chainable.
Snow chains are permitted with the use of
225/65R17 tires on size 17 x 7.5 ET31
wheels.
Use reduced size snow chains with a
maximum projection of 9 mm beyond the
tire profile.
CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing
compounds. They will permanently
damage this finish and such damage is not
covered by the New Vehicle Limited
Warranty. HAND WASH ONLY USING
MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all
that is required to maintain this finish.
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.

Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform
different steering, handling, and braking
functions. For these reasons, they wear at
unequal rates.These effects can be reduced by timely rota
-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off Road type
tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested Front Wheel Drive (FWD) rota -
tion method is the “forward cross” shown in
the following diagram. This rotation pattern
does not apply to some directional tires that
must not be reversed.
Tire Rotation (Forward Cross)
CAUTION!
Use on Front Tires Only
Damage to Front Wheel Drive (FWD)
Models may result if tire chains or trac-
tion devices are used with original equip -
ment size tires.
Damage to Four Wheel Drive (4WD)
Models without a Two-Speed Power
Transfer Unit may result if tire chains or
traction devices are used with original
equipment size tires.
Damage to Four Wheel Drive (4WD)
Trailhawk Models may result if tire
chains or traction devices are used with
original equipment size tires.
To avoid damage to your vehicle or tires,
observe the following precautions:

Because of restricted traction device clear -
ance between tires and other suspension
components, it is important that only trac -
tion devices in good condition are used.
Broken devices can cause serious damage.
Stop the vehicle immediately if noise
occurs that could indicate device
breakage. Remove the damaged parts of
the device before further use.

Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km). Autosock traction devices do
not require retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
Do not drive for a prolonged period on
dry pavement.

Observe the traction device manufac -
turer’s instructions on the method of
installation, operating speed, and condi -
tions for use. Always use the suggested
operating speed of the device manufac -
turer’s if it is less than 30 mph (48 km/h).

Do not use traction devices on a compact
spare tire.
