Defrost Mode
Air comes from the windshield and side window demist
outlets. Use this setting when necessary to defrost your
windshield and side windows.
NOTE: While operating in either  Auto HI  or  Auto
LO  , the system will not automatically sense the presence of fog, mist, or ice on the windshield.  Defrost  mode
must be manually selected to clear the windshield and
side glass.
The  snowflake  or  a/c  button allows the opera-
tor to manually activate or deactivate the air
conditioning system. When the snowflake symbol
in 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 snowflake icon in the
ATC display and deactivate the air conditioning system.
Note: While operating in  auto hi  or  auto lo  , the air
conditioning system is always activated. 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, high
humidity, or if rapid cooling is desired, you
may wish to recirculate interior air by pressingDefrost Outlets278 UNDERSTANDING YOUR INSTRUMENT PANEL

the recirculation button. The recirculation mode should
only be used temporarily. The recirculation symbol will
illuminate in the display when this button is selected.
Push the button a second time to turn off the recirculation
icon in the display and allow outside air into the vehicle.
NOTE: In cold weather, use of the Recirculation mode
may lead to excessive window fogging. The Recirculation
mode is not allowed in the Mix and Defrost modes to
improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.
Auxiliary Rear Automatic Temperature Control —
If Equipped
The Rear Automatic Temperature Control System has
floor air outlets to the rear of the right side sliding door
and overhead outlets at each outboard rear seating
position. The system provides heated air through the
floor outlets or cool, dehumidified air through the head-
liner outlets. The “ REAR SYSTEM ” knob for the Rear Automatic
Temperature Control System is on the front ATC control
unit located on the instrument panel.
Selecting the “ AUTO ” position for the Rear Automatic
Temperature Control System from the front ATC control
unit, illuminates a “ LOCK ” symbol in the rear display.
The rear temperature and air source are controlled from
the front ATC control unit.
The “ REAR SYSTEM ” knob on the front ATC control unit
has three positions, “ REAR CONTROL ” , “ OFF ” , and
“ AUTO ” . Only when the “ REAR SYSTEM ” knob is in the
“ REAR CONTROL ” position do the second seat occu-
pants have control of the Rear Automatic Temperature
Control System. UNDERSTANDING YOUR INSTRUMENT PANEL 279

glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
To insure 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, Maintenance
Procedures, 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 condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate system lubrication to minimize the possibility of com-
pressor 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  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.
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 and if they
enter the plenum they could plug the water drains. In
winter months make sure the air intake is clear of ice,
slush and snow. UNDERSTANDING YOUR INSTRUMENT PANEL 283

Intermittent Rear Wiper Operation — Automatic
Temperature Control Only
When this button is pressed and the ignition
switch is in the ON position, the rear wiper will
operate at a fixed interval of about 8 seconds. As
vehicle speed increases, the time delay will shorten. The
switch position as well as an indicator light will show
when the wiper is ON.
Rear Washer Operation — Automatic
Temperature Control Only
Press and hold the button as long as spray is
desired. If the switch is depressed while the wipers
are on, the wipers will operate for a few seconds
after the switch is released then resume the previously set
mode of intermittent wiper or continuous wipe. If the
switch is depressed when the wipers are off, the wipers
will operate for two cycles, then turn off. NOTE: The washers will stop spraying if the switch is
pressed longer than 10 seconds.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.286 UNDERSTANDING YOUR INSTRUMENT PANEL

Reset Mode - Electronic Transmission
The transmission is monitored electronically for abnor-
mal conditions. If a condition is detected that could cause
damage, the transmission automatically shifts into sec-
ond gear. The transmission remains in second gear
despite the forward gear selected. Park (P), Reverse (R),
and Neutral (N) will continue to operate. This Reset
feature allows the vehicle to be driven to a dealer for
service without damaging the transmission.
In the event that the problem has been momentary, the
transmission can be reset to regain all forward gears.
• Stop the vehicle and shift into Park (P).
• Turn the key to OFF then restart the engine.
• Shift into the desired range and resume driving.
NOTE: Even if the transmission can be reset, it is
recommended that you visit a dealer at your earliest possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
• “ P ” Park
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never
attempt to use PARK while vehicle is in motion. Transmission Gear Ranges STARTING AND OPERATING 299

A load equalizing hitch is recommended for loaded
trailer weights above 1,000 lbs (454 kg) and required for
weights above 2,000 lbs (907 kg).
Special care should be taken when towing a trailer with
heavy duty trailer tow package, without a load equaliz-
ing hitch, and with 6 to 7 passengers, to insure the rear
GAWR is not exceeded. Depending on your vehicle
model and options, the maximum trailer weight could
range from 0 to 2000 pounds.
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!Connecting trailer brakes to your vehicle ’ s hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident. STARTING AND OPERATING 341
