TIRE PRESSURE MONITOR SYSTEM (TPMS) Ð IF
EQUIPPED
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure (the placard is lo-
cated on the driver's side B-pillar).
The tire pressure will vary with temperature by about 1
psi (6.9 kPa) for every 12ÉF (6.5ÉC). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after a vehicle has not been driven for more than
three hours - and in outside ambient temperature.Refer
to the ªTires ± General Informationº in this section for
information on how to properly inflate the vehicle's
tires. The tire pressure will also increase as the vehicle is
driven - this is normal and there should be no adjustment
for this increased pressure.TPMS will warn the driver of a low tire pressure if the tire
pressure falls below the low pressure warning threshold
for any reason, including low temperature effects, or
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 recommended
cold placard pressure. Once the low tire pressure warn-
ing has been illuminated, the tire pressure must be
increased to the recommended cold placard pressure in
order for the TPMS warning light to be turned off. The
system will automatically update and the TPMS warning
light p will extinguish once the updated tire pressures
have been received. The vehicle may need to be driven
for up to 10 minutes above 15 mph (25 km/h) to receive
this information.
324 STARTING AND OPERATING

For example, your vehicle has a recommended cold
(parked for more than three hours) placard pressure of 33
psi (227 kPa). If the ambient temperature is 68ÉF (20ÉC)
and the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20ÉF (-7ÉC) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn on the TPMS
light. Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the TPMS light
will still be ON. In this situation, the TPMS light will turn
off only after the tires have been inflated to the vehicle's
recommended cold placard pressure value.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket tire sealants or balance beads if your
vehicle is equipped with a TPMS, as damage to the
sensors may result.

CAUTION!
After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the tire pressure monitoring sensor.
NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving 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.
²The 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 gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Lamp.
²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System ± If Equipped
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.
326 STARTING AND OPERATING

NOTE:It is particularly important for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
²Receiver module
²Four tire pressure monitoring sensors
²Tire Pressure Monitoring Telltale Lamp
The Tire Pressure Monitoring Telltale Lamp will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. 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. The system will automatically update
and the Tire Pressure Monitoring Telltale Lamp will
extinguish once the updated tire pressures have beenreceived. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. 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 Lamp will turn off when the
fault condition no longer exists. A system fault can occur
by any of the following scenarios: 1) Jamming due to
electronic devices or driving next to facilities emitting the
same radio frequencies as the TPM sensors; 2) Installing
some form of aftermarket window tinting that affects
radio wave signals; 3) Lots 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 TPMS consists of the following components:
²Receiver module
²Four tire pressure monitoring sensors
²Three trigger modules (mounted in three of the four
wheel wells).
²Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and a
graphic displaying tire pressures.
²Yellow Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. In addition, the EVIC will display a
graphic of the pressure value(s) with the low tire(s)
flashing.Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle's recommended cold placard pres-
sure value. The system will automatically update, the
graphic display of the pressure value(s) will stop flash-
ing, and the Tire Pressure Monitoring Telltale Light will
extinguish once the updated tire pressure(s) have been
received. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
Check TPMS Message
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a ªCHECK TPM SYS-
TEMº message for three seconds. This text message is
then followed by a graphic display, with ª- - -ª in place of

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the component in the
system with the lowest load carrying capacity (axle,
springs, tires, or wheels).
Heavier axles or suspension components sometimes
specified by purchasers for increased durability do not
necessarily increase the vehicle's GVWR.
Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure (Cold)
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to ensure that the GVWR has not been ex-
ceeded. The weight on the front and rear of the vehicle

Towing Requirements Ð Tires
þ
Do not attempt to tow a trailer while using a compact
spare tire.
þProper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. For proper
tire inflation procedures, refer to ªTire Pressuresº
under ºTires±General Informationº in Section 5.
þAlso, check the trailer tires for proper tire inflation
pressures before trailer usage.
þCheck for signs of tire wear or visible tire damage
before towing a trailer. For the proper inspection
procedure, refer to ªTread Wear Indicatorsº under
ºTires±General Informationº in Section 5.
þWhen replacing tires, refer to ªReplacement Tiresº
under ªTires±General Informationº in Section 5. Re-
placing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
Towing Requirements Ð Trailer Brakes
þ
Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
354 STARTING AND OPERATING

3. Turn the wrench counterclockwise to lower the spare
tire. Continue to turn the wrench until the spare tire can
be pulled out from under the vehicle.
It is recommended that you stow the flat tire or spare to
avoid tangling the loose cable.
CAUTION!
The winch mechanism is designed for use with the
jack extension tube only. Use of an air wrench or
other power tools is not recommended and can dam-
age the winch.
Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service center
where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The scissor
jack is designed as a tool for changing tires on this vehicle
only. It is not recommended that the jack be used for
service purposes or to lift more than one wheel at a time.
