Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in
fresh air with the blower setting in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again. Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost on
the inside of the glass in very cold weather. To clear the
windows, select Defrost or Mix mode and increase the front
blower speed. Do not use the Recirculation mode without
A/C for long periods, as fogging may occur.
NOTE: Automatic Temperature Controls (ATC) will au-
tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow. 4UNDERSTANDING YOUR INSTRUMENT PANEL 371

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 10-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.

running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the Key Fob.
When the ignition is in the LOCK/OFF (key re-
moval) position, the transmission is locked in
PARK, securing the vehicle against unwanted
movement.

If the ignition switch 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 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:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains
materials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.Tire Pressure Monitor Display494 STARTING AND OPERATING

The TPIS consists of the following components:
• Receiver module
• Four TPM sensors (Single Rear Wheel [SRW] applica-
tions)
• Six TPM sensors (Dual Rear Wheel [DRW] applica-
tions)
• Pressure display in the Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID)
The TPIS system will display all four (Single Rear Wheel
[SRW] applications) or six (Dual Rear Wheel [DRW]
applications) tire pressure values EVIC/DID display.
If a system fault is detected, the EVIC/DID 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 switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the  SERVICE TPM SYSTEM  message
will no longer be displayed, and a pressure value will

WARNING! (Continued)time the vehicle is raised. Have any abnormal
conditions repaired promptly. Until repaired, drive
with all side windows fully open.
ADDING FUEL
CAUTION!• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (fuel filler cap). A poorly fitting
cap could let impurities into the fuel system. Also,
a poorly-fitted aftermarket cap can cause the MIL
(Malfunction Indicator Light) to illuminate due to
fuel vapors escaping from the system.
• A poorly fitting fuel filler cap may cause the MIL to
turn on. (Continued) CAUTION! (Continued)• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE: When the fuel nozzle “clicks” or shuts off the
fuel tank is full.
WARNING!• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel to the vehicle when the engine is
running. This is in violation of most state and
federal fire regulations and may cause the MIL to
turn on. 5STARTING AND OPERATING 503

cleaner. Use caution when cleaning the inside rear win-
dow equipped with electric defrosters or windows
equipped with radio antennas. Do not use scrapers or
other sharp instrument that may scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or cloth that you are using. Do not spray cleaner
directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap solution may
be used, but do not use high alcohol content or
abrasive cleaners. If soap is used, wipe clean with a
clean damp cloth.
2. Dry with a soft cloth. Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the
vehicle to wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
WARNING!A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do
not disassemble or modify the system. Seat belt (Continued)606 MAINTAINING YOUR VEHICLE
