WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause accidents.
•Under-inflation increases tire flexing and can re-
sult in over-heating and tire failure.
•Over-inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
•Over-inflated or under-inflated tires can affect
vehicle handling and can fail suddenly, resulting
in loss of vehicle control.(Continued)

WARNING! (Continued)
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
TIRE CHAINS
Use “Class S” chains or other traction aids that meet SAE
Type “S” specifications.
NOTE:Chains must be the proper size for the vehicle as
recommended by the chain manufacturer.
CAUTION!
To avoid damage to your vehicle, tires or chains,
observe the following precautions:
•Because of limited chain clearance between tires
and other suspension components, it is important
that only chains in good condition are used. Bro-
ken chains can cause serious vehicle damage. Stop
the vehicle immediately if noise occurs that could
suggest chain breakage. Remove the damaged
parts of the chain before further use.
•Install chains as tightly as possible and then
retighten after driving about 1/2 mile (0.8 km).
•Do not exceed 45 mph (72 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 pave-
ment.

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 “Tire Pressure
Monitoring Telltale Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base 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 Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light

STARTING AND OPERATING 351
Page 353 of 498

The matching full-size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The
matching full-size spare can be used in place of any of the
four road tires. The TPMS will only monitor the pressure
in the full-size spare when it is used in place of a road
tire. Otherwise, a spare with a pressure below the low-
pressure limit will not cause the “Tire Pressure Monitor-
ing Telltale Light” to illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring 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. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value. Once the system receives the updated tire pres-
sures, the system will automatically 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 (25 km/h) in order for the TPMS to receive this
information.
Check 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 also sound a chime. If the ignition key is cycled, this
sequence will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale Light” will
turn off when the fault condition no longer exists. A
system fault can occur due to any of the following:
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.

Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring 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
Electronic Vehicle Information Center (EVIC) will display
a graphic showing the pressure values of each tire with
the low tire pressure values flashing. Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, 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 (25 km/h) in order for the
TPMS to receive this information.
Check 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 also sound a chime. In addition, the EVIC will
display a
CHECK TPM SYSTEM message for three
seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can
kill. Never run the engine in a closed area such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.(Continued)
WARNING! (Continued)
•Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
•Keep the liftgate closed when driving your vehicle
to prevent carbon monoxide and other poisonous
exhaust gases from entering the vehicle.

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in an
accident.
Towing Requirements – Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The trailer tow package may include a four-pin and
seven-pin wiring harness. Use a factory approved trailer
harness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
