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
•Three Trigger Modules (mounted in three of the four
wheel-wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Tire Pressure Monitoring Telltale LightTire 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 show-
ing 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 all 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 (24 km/h) in order for the
TPMS to receive this information.
Check TPMS Warning
When a system fault is detected, a chime will sound and
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 aCHECK TPM SYS-
TEMmessage 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 Telltale
Light” will no longer flash, and theCHECK TPM
SYSTEMmessage 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. 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 EVIC will also display aCHECK 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, theCHECK TPM SYSTEMmes-
sage is then followed with a graphic display with pres-
sure 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.
368 STARTING AND OPERATING
Page 371 of 519

The system still needs to be serviced as long as the
CHECK TPM SYSTEMmessage is displayed.
NOTE:
1. The compact spare tire (if so equipped) does not have
a tire pressure monitoring 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 key cycle, the “Tire
Pressure Monitoring Telltale Light” will remain ON, a
chime will sound, and the EVIC will still display a
flashing pressure value in the graphic display.3. 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 aCHECK TPM SYSTEMmessage for a
minimum of five seconds and then display dashes (- -)
in place of the pressure value.
4. For each subsequent ignition key 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 aCHECK TPM
SYSTEMmessage for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.

5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“Tire Pressure Monitoring Telltale Light” will turn
OFF and the graphic in the EVIC will display a new
pressure value instead of dashes (- -), as long no tire
pressure is below the low-pressure warning limit in
any of the four active road tires. 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.

•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
•Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
•Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
•When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for the proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.Towing Requirements – Trailer Brakes
•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.
•An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.

WARNING!
•To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle
has been lowered. Failure to follow this warning
may result in personal injury.
•To avoid possible personal injury, handle the
wheel covers with care to avoid contact with any
sharp edges.
7. Lower the vehicle by turning the jack screw to the left.
8. Finish tightening the nuts. Push down on the wrench
while at the end of the handle for increased leverage.
Tighten the lug nuts in a star pattern until each nut has
been tightened twice. The correct wheel nut torque is
100 ft lbs (135 N·m). If you doubt that you have
tightened the nuts correctly, have them checked with a
torque wrench by your authorized dealer or at a
service station.9. Remove the wheel blocks and lower the jack until it is
free. Release the parking brake before driving the
vehicle. Reassemble the lug wrench to the jack assem-
bly and stow it in the spare tire area. Secure the
assembly using the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
10. Place the deflated (flat) tire in the cargo area andhave
the tire repaired or replaced as soon as possible.
11. Check the tire pressure as soon as possible. Correct
the tire pressure as required.

WHAT TO DO IN EMERGENCIES 407
Page 463 of 519

CAUTION!
Avoid high-pressure car washes, as they can damage
the top material. Also, increased water pressure may
force water past the weather strips.
General Cleaning
Careful vacuuming of the top before washing is helpful
in removing dust and other foreign particles. Wash in
partial shade instead of direct sun. Wet the entire vehicle
before washing the top. The top should be washed with
a soft, natural bristle scrub brush, and a mild soap
solution such as liquid dishwashing soap. Do not use
detergent.
CAUTION!
Never use an abrasive type cleaner or bleaches.
Cleaners should not contain silicones, organic sol-
vents, petroleum distillates, or plasticizers. Always
wait until the top is thoroughly dry before lowering
it into the storage area.
Scrub in all directions, covering an area of about two
square feet at a time. Avoid heavy scrubbing. Rinse the
entire vehicle with water to remove all soap and dirt from
the top fabric and to prevent streaking on painted and
chrome surfaces. Allow the top to dry before lowering.
Vacuuming the top with a wet/dry shop vacuum will
decrease the top’s drying time, ensure removal of all dirt,
and delete streaks in the material. Multiple cleanings
may be necessary to remove stubborn stains. If stains
persist, contact your local dealership for further sugges-
tions.

MAINTAINING YOUR VEHICLE 461
Page 482 of 519

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Required” in
“Understanding Your Instrument Panel” for further in-
formation
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
•Check engine oil level
•Check windshield washer fluid level
•Check the tire inflation pressures and look for unusual
wear or damage
•Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
•Check function of all interior and exterior lights
