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:For improved safety, the compressor is activated
and the recirculation mode is deactivated when Mix orDefrost modes are selected. This is done to assist in
drying the air and it will help in keeping the windows
from fogging.
Manual Air Conditioning Operation
To turn on the air conditioning, set the front
blower control to any speed and press the A/C
button which is located next to the recirculation
button. An indicator light on the A/C button shows that
the air conditioning is on.
NOTE:The indicator light in the “POWER” button must
be on for the climate control system to operate.
Cool dehumidified air comes through the outlets selected
by the Mode Control. To turn off the air conditioning,
press the A/C button a second time. The indicator light
will turn off.

NOTE:
•The compressor will not engage until the engine has
been running for a few seconds.
•If your air conditioning performance seems lower than
expected, check the A/C air filter (ATC equipped
vehicles only) and the front of the A/C condenser for
an accumulation of dirt or insects. The A/C condenser
is located in front of the radiator. The A/C air filter is
located under the instrument panel on the passenger
side.
•Fabric type fascia protectors tend to block the amount
of air to the condenser and may reduce air condition-
ing performance.
Economy Mode
If economy mode is desired, press the A/C button to turn
off the indicator light, and the A/C compressor. Move the
temperature control lever to the desired temperature.
Recirculation Control
Press the recirculation button to recirculate the
air inside the vehicle. This is located next to the
A/C button. An indicator light on the button
shows that air is being recirculated. Use the
recirculation mode to rapidly cool the inside of the
vehicle. The recirculation mode can also be used to
temporarily block out outside odors, smoke, and dust.
NOTE:
•When the ignition switch is turned OFF, the recircula-
tion feature will be cancelled.
•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.

•If the recirculation button is pressed while in the Mix
or Defrost mode, the indicator light in the recirculation
button will flash 3 times indicating that recirculation is
not allowed.
A/C Recirculation Programming
The recirculation control is programmed to cancel the
recirculation mode when the ignition key is turned OFF
and will reset to outside air mode when the ignition key
is turned ON. The frequent use of outside air will help
keep odors from building up within the air conditioner-
heater housing. It is recommended that the recirculation
mode be used as little as possible, especially in humid
climates.
For hot and dry climates, or people who are allergic to
pollen and find frequent use of the recirculation mode
necessary, the recirculation mode can be programmed to
not automatically reset to the outside mode by using the
following procedures:
•Turn the ignition switch to the OFF position.
•Set the mode control to “PANEL”.
•Depress and hold in the “POWER” button.
•Start the engine, and continue to hold in the “POWER”
button until the indicator light starts flashing repeat-
edly.
•Press the recirculation button until the indicator light
remains lit.
•The selection will be stored when the ignition switch is
turned OFF or if the “POWER” button is pressed.
If the recirculation indicator light is lit, the recirculation
mode will not reset when the engine is started. If the
recirculation indicator light is not lit, the recirculation
mode will reset to the outside air mode when the engine
is started. The programmed status can be changed back
and forth by following the above mentioned procedure.

Dual-Zone Automatic Temperature Control
The Dual Zone Automatic Temperature Control (ATC)
System automatically maintains the interior comfort level
desired by the driver and front seat passenger. This is
accomplished by using two infrared sensors located in
the center of the instrument panel. The two infrared
sensors independently measure the surface temperature
of the driver and front seat passenger. Based on the
sensor input, the system automatically adjusts the air
temperature, the airflow volume, the airflow distribu-
tion, and amount of inside air recirculation to maintain
front seat occupant comfort, even under changing out-
side weather conditions.
To operate the system, press either theAUTO HIor
AUTO LObuttons. The system now automatically
regulates the heating and air conditioning system includ-
ing blower speed, outlet air temperature, and airflow
distribution through the various outlets within the in-
strument panel. Using theTEMPbuttons, adjust the

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.
A/C Recirculation Programming
The recirculation control is programmed to cancel the
recirculation mode when the ignition key is turned OFF
and will reset to the outside air mode when the ignition
key is turned “ON”. The frequent use of outside air will
help keep odors from building up within the air
conditioner-heater housing. It is recommended that the
recirculation mode be used as little as possible, especially
in humid climates.
For hot and dry climates, or people who are allergic to
pollen and find frequent use of the recirculation mode
necessary, the recirculation mode can be programmed to
not automatically reset to the outside mode by using the
following procedures:

The ABS light monitors the Anti-Lock Brake
System. The light will come 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 comes 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.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•the clicking sound of solenoid valves,
•brake pedal pulsations,
280 STARTING AND OPERATING

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 3 hours, or driven less than 1 mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure 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
