also be shown in the display and will change as
required during automatic operation.
•The system can be put into recirculate mode without
affecting ATC operation. This will prevent outside air
from entering the vehicle. Use this mode to tempo-
rarily block out any outside odors, smoke, or dust.
Manual Control (ATC)
You may also choose to customize your comfort by
selecting the fan speed and mode manually. Turning the
fan speed knob or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or - Temp rocker switches.
FAN Control
Use this knob to regulate the amount of air delivered
through the system in any mode you select. Rotation
of the knob to increase (clockwise) or decrease (counter-
clockwise) fan speed.
Air Conditioning Operation
Press this button to enable the air conditioning
system. Compressor operation is automatic when
you press the AUTO button and no snowflake is
shown. A snowflake indicates that the A/C system is
enabled. The snowflake will not be displayed in AUTO
mode even though the A/C system is enabled.
The compressor may operate at any temperature above
32°F (0°C).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in

engine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.
Manual control of recirculation is possible only in Panel,
Floor, and Bi-Level modes. It will not operate in Mix, or
Defrost modes. The recirculation symbol will flash three
times indicating recirculation is not available in these
modes.NOTE:If the interior of the windows begin to fog, press
the Recirculate button to return to outside air. Some
conditions will cause captured interior air to fog win-
dows when in recirculate mode.
Panel
Air flows through the outlets located in the instru-
ment panel. These outlets can be adjusted to direct
the airflow.
Floor (Heat)
Air flows primarily through the floor outlets lo-
cated under the instrument panel. A small amount
of air is directed through the defrost and side window
demister outlets.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.
276 UNDERSTANDING YOUR INSTRUMENT PANEL

Bi-Level
Air flows through the outlets located in the instru-
ment panel and those located on the floor.
NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Defrost
Outside air is directed to the windshield through
the defroster outlet located at the base of the
windshield and side window demist outlets.
NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes, even if
the A/C snowflake button has not been pressed. This
dehumidifies the air to help dry the windshield.
Rear Temperature Control (ATC)
The REAR button cycles through the following modes:
Rear Control From Front
This allows the driver or passenger to control the rear
blower speeds rotating the Power/Fan knob and the rear
temperature using the PASS/REAR Temp +/- rocker
switch. While in this mode, pressing the POWER/FAN
knob will turn the rear system off. Pressing the Power/
Fan knob will turn the rear system back on.
NOTE:The display will show aREARfan speed graph
and aREARdigital temp setting.
CONTROL IN REAR
This allows the passengers in the second row seats to
control the blower speed and temperature by means of
the rear control located in the rear of the center floor
console as described under theRear Zone Climate
Control.

Headliner 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 vane knobs on the
outlets to one side will shut off the airflow.
The rear compartment control uses two rotary knobs: one
for the temperature control and the other for the fan
speed control. The mode for the rear air conditioning andheating system is always controlled by the front control
unit. Fan and temperature can be controlled from the
front control unit or the rear control unit.
Rear Rotary Blower Control
The second row seat occupants have control of the rear
blower speed only when the front control unit is in the
“REAR CONTROL” position or “CONTROL IN REAR
for ATC.
The rear blower switch has an OFF position and a range
of blower speeds. Rotating the rear blower control clock-
wise will increase the blower speed.
Rear Rotary Temperature Control
The second row seat occupants have control of the rear
temperature only when the front control unit is in the
REAR CONTROLposition.

Operating Tips
Fast Cooldown
For a fast cooldown, set the blower fan to the highest
setting, set the mode control to the panel fresh position,
press the Snowflake button to turn on the air condition-
ing, and drive with the windows open for the first few
minutes. Once the hot air has been expelled, close the
windows and set the mode selector to the Recirculation
panel or Recirculation Bi-level position. When a comfort-
able condition has been reached, choose a mode positionand adjust the temperature control and blower speed as
necessary to maintain comfort. For high humidity condi-
tions, it may be necessary to remain in the Recirculation
mode to maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning on the air conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using Mix Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminants (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminants increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions. This will also prevent snow ingestion into the
ducts.

CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.” Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least three hours or driven less than
1 mile (1.6 km) after a three hour period. The cold tire
inflation pressure must not exceed the maximum infla-
tion pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures as tire pressures vary with
temperature changes.Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. Do not reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle

WARNING!
The limited-use spare tires are for emergency use
only. Installation of this limited-use spare tire affects
vehicle handling. With this tire, do not drive more
than 50 mph (80 km/h). Keep it inflated to the cold
tire inflation pressure listed on either your tire plac-
ard or limited-use spare tire and wheel assembly.
Replace (or repair) the original tire at the first oppor-
tunity and reinstall it on your vehicle. Failure to do
so could result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping when you are stuck.For additional information, refer to “Freeing A Stuck
Vehicle” in Section 6.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
30 mph (48 km/h) or for more than 30 seconds
continuously when you are stuck, and do not let
anyone near a spinning wheel, no matter what the
speed.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.

MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
or not his/her gasoline contains MMT. It is even more
important to look for gasolines without MMT in Canada,
because MMT can be used at levels higher than thoseallowed in the United States. MMT is prohibited in
Federal and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emission control system.

WARNING! (Continued)
•Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
•Keep the trunk/liftgate/swing gate closed when
driving your vehicle to prevent carbon monoxide
and other poisonous exhaust gases from entering
the vehicle.
