Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.WARNING!

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON position.
2. Fuel Door Reminder
The arrow in this symbol is a reminder that the
Fuel Filler Door is located on the left side of the
vehicle.
3. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads
ªHª, pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the ªHº, and you hear continuous chimes,
turn the engine off immediately, and call an autho-
rized dealer for service.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer if
your vehicle overheats. If you decide to look under
the hood yourself, see Section 7 of this manual.
Follow the warnings under the Cooling System Pres-
sure Cap paragraph.
4. Speedometer
Indicates vehicle speed.
5. Turn Signal Indicators
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, acontinuous chime will sound to alert you to turn the
signals off. If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
6. High Beam Light
This light shows that the headlights are on high
beam. Pull the turn signal lever towards the
steering wheel to switch the headlights from high or low
beam.
7. Anti-Lock Brake System Light
This light monitors the Anti-Lock Brake Sys-
tem. The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.

The SNOWFLAKE mode or A/C button allows
the operator to manually activate or deactivate the
air conditioning system. When in SNOWFLAKE
mode the ATC display is on, cool, dehumidified air flows
through the air outlets. If ECONOMY mode is desired,
press the SNOWFLAKE button to turn off the SNOW-
FLAKE mode in the ATC display and deactivate the A/C
system. Note: If fog or mist appears on the windshield or
side glass, select DEFROST mode and increase blower
speed.
RECIRCULATION Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION mode control
button. RECIRCULATION mode should only be used
temporarily. The recirculation symbol will illuminate in
the display when this button is selected. Push the buttona second time to turn off the RECIRCULATION mode
LED and allow outside air into the vehicle.
NOTE:In cold weather, use of the RECIRCULATION
mode may lead to excessive window fogging. The RE-
CIRCULATION mode is not allowed in the FLOOR, MIX
and DEFROST modes to improve window clearing op-
eration. Recirculation will be disabled automatically if
these modes are selected. Recirculation will be disabled
automatically if these modes are selected.
Rear Automatic Temperature Control (ATC) Ð If
Equipped
The Rear ATC System has floor air outlets at the rear of
the right side sliding door and overhead outlets at each
outboard rear seating positions. The system provides
heated air through the floor outlets or cool, dehumidified
air through the headliner outlets.

HEADLINER Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vanes of the outlets to one
side will shut off the airflow.
SUMMER OPERATION
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to section 7, ªMaintenance Proceduresº, of this manual
for proper coolant selection.
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 section 7,ªMaintenance Proceduresº, of this manual for proper
coolant selection. Use of the air RECIRCULATION mode
during winter months is not recommended because it
may cause window fogging.
VACATION/STORAGE
Anytime 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 the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
WINDOW FOGGING
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select DE-
FROST 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.

406 STARTING AND OPERATING

HAZARD WARNING FLASHER
The hazard flasher switch is located in the center of
the instrument panel below the radio.
To engage the Hazard Warning Flashers, depress the
switch on the instrument panel. When the Hazard Warn-
ing Switch is activated, all directional turn signals will
flash on and off to warn oncoming traffic of an emer-
gency. Push the switch a second time to turn off the
flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning Flashers will continue to operate even
though the ignition switch is OFF.NOTE:With extended use, the Hazard Warning Flash-
ers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, shift the transmission
gear selector lever into NEUTRAL, but do not increase
engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
