If the pointer rises to the “H” mark, stop the vehicle and
turn off the engine until the problem is corrected.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning 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
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
16. Malfunction Indicator Light
This light is part of an onboard diagnostic
system called OBD that monitors engine and
automatic transmission control systems. The
light will illuminate when the key is in the ON
position before engine start. If the bulb does not come
on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap or
poor fuel quality may illuminate the light after engine
start. The vehicle should be serviced if the light stays onthrough several of your typical driving cycles. In most
situations the vehicle will drive normally and will not
require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced as soon as possible if this occurs.
17. Trip Odometer Reset Knob
To reset the trip odometer, push the reset knob for about
two seconds.
18. Airbag Light
The light will come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch
is first turned ON. If the bulb is not lit during starting,
have it replaced. If the light stays on, or comes on
while driving, have the system checked by an autho-
rized dealer.
19. Odometer/Trip Odometer
Shows the total distance the vehicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the

CLIMATE CONTROLS
Manual Air Conditioning/Heater Operation
The Air Conditioning System allows you to balance the
temperature, amount, and direction of the air circulating
throughout the vehicle.
The controls are as follows:
Fan Control
Use this control to regulate the amount of air forced
through the system in any mode you select. Turn the
control clockwise to increase fan speed. Turn the controlto the O (Off) position to shut off the fan and to prevent
any outside air from entering the vehicle. This also turns
off the A/C compressor.
Temperature Control
Use this control to regulate the temperature of the air
inside the passenger compartment. The blue area of the
control indicates cooler temperatures while the red area
indicates warmer temperatures.
Mode Control
Use this control to direct the flow of air as follows:
NOTE:The dot between the mode control icons is a mix
position between the two modes.
Recirculate
Air is recirculated inside the vehicle. You may
choose between Bi-Level and Panel air outlets
while in this mode. Use this mode to temporarily
block out any outside odors, smoke, or dust and to
cool the interior rapidly upon initial start up in very
hot or humid weather.

NOTE:The air conditioning compressor operates in
this mode. This dehumidifies the air to help dry the
windshield. To improve fuel economy, leave in the De-
frost mode only when necessary.
A/C Pushbutton
With the fan control in the ON position, push-
ing the A/C button turns on the air condition-
ing compressor. An indicator light above the
button shows that the Air Conditioning compressor is
on. Conditioned air is now directed through the
outlets selected. Pushing the button a second time
turns the compressor OFF.
Slight changes in engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects. Clean with
a gentle water spray from behind the radiator andthrough the condenser as required. Fabric front fascia
protectors may reduce air flow to the condenser, reducing
air conditioning performance.
NOTE:See Operating Tips chart (for both Manual A/C
and ATC systems) at the end of this section for suggested
control settings in different weather conditions.
Rear Window Defroster
Press the button once to turn on the Rear Window
Defroster and a second time to turn it off. A light
above the button shows that the Rear Defroster is On.

compressor. A snow flake symbol in the display
shows that the compressor is on. Compressor
operation is automatic when you press the Auto button.
The compressor can operate at any temperature above
32°F (0°C).
With the compressor off and the temperature set at Lo, air
entering the vehicle will be slightly warmer than the air
outside the vehicle.
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes inengine speed or power may be noticed when the com-
pressor is on. 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. Recirculation is automatically controlled when
the system is in Auto Mode. Use this mode to temporarily
block out any outside odors, smoke, or dust.
Manual control of Recirculation is possible only in Panel,
Floor, and Bi-Level modes. It will not operate in Mix, or
Defrost modes.
NOTE:The Recirc button light will blink if you try to
use it in the Mix or Defrost modes.
Air Direction Buttons (Mode)
These buttons allow you to select from five air distribu-
tion patterns. These buttons should be used only when
you can not achieve comfort or visibility in Auto opera-
tion. A symbol in the display window will show which
mode is operating.

Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
air flow. This mode is not recommended when heat is
required.
Floor
Air is directed through the floor outlets with a
lesser amount through the Defrost and side
window demist outlets. This mode is recommended
when heat is desired.
Mix
Air is directed through the floor, defrost, and
side window demist outlets. Use this setting in
cold or snowy conditions that require extra heat
at the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield.
The compressor is on in this mode.
Bi-Level
Air is directed through both the panel and floor
outlets. This mode is not recommended when
heat is required in very cold temperatures.NOTE:There is a varying difference in temperature
between the upper and lower outlets for added comfort.
The warmer air goes to the floor outlets. This feature
provides improved comfort during sunny but cool con-
ditions.
Windshield Defrost
Air is directed through the defrost outlets and
side window demist outlets. A small amount of
air also is directed through the floor outlets. Use this
mode with maximum fan and comfort level settings
for best windshield and side window defrosting. The
defrost symbol will glow in amber to show that the
defroster is on.
NOTE:
The air conditioning compressor is on in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the defrost
mode only when necessary.
Rear Window Defroster
Press the button once to turn on the Rear Window
Defroster and a second time to turn it off. An

behind the steering wheel. Push in the flasher
switch and all front and rear directional signals
will flash. Press the flasher switch a second time to turn
the flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may run 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.
•On the highways — Slow down.
•In city traffic — While stopped, put transaxle in
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
176 WHAT TO DO IN EMERGENCIES

CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and identified on the battery case.
Cable clamps should be tight on the terminal posts
and free of corrosion. Apply grease to posts and
clamps after tightening. If a “fast charger” is used
while the battery is in the vehicle, disconnect both
vehicle battery cables before connecting the charger
to battery. Do not use a “fast charger” to provide
starting voltage as battery damage can result.
Air Conditioner
Check the air conditioning system at the start of the
warm weather season.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects. Clean with
a gentle water spray from behind the radiator and
through the condenser as required. Fabric front fascia
protectors may reduce air flow to the condenser, reducing
air conditioning performance.
WARNING!
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal injury
or damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced repairman.
204 MAINTAINING YOUR VEHICLE

Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere. The manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recyling and recovery equipment that meets
SAE standard J1991.
Power Steering Fluid Check
WARNING!
Fluid level should be checked with the engine off to
prevent injury from moving parts. Do not overfill.
Use only the manufacturer’s recommended power
steering fluid. Refer to Recommended Fluids, Lubri-
cants and Genuine Parts for the correct fluid type.
During scheduled maintenance, check the power steering
fluid level at the power steering fluid reservoir.
Before removing the reservoir cap, wipe the outside of
the cap and reservoir so that no dirt can fall into the
reservoir.

•Maintain coolant concentration of a minimum of 50%
ethylene glycol and high quality water with recom-
mended antifreeze for proper corrosion protection of
your engine cooling system that contains aluminum
components.
•Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
•Keep the front of the radiator and air conditioning
condenser clean.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in Section 8.
