CLIMATE CONTROL SYSTEM
Manual heating and air conditioning system
Fan speed control
Controls the volume of
air circulated in the
vehicle.
Temperature control knob
Controls the
temperature of the
airflow inside the
vehicle.
Mode selector control
Controls the direction
of the airflow to the
inside of the vehicle.
The air conditioning compressor will operate in all
modes except VENT and FLR. However, the air
conditioning will only function if the outside
temperature is about 10ÉC (50ÉF) or higher.
Since the air conditioner removes considerable
moisture from the air during operation, it is normal
if clear water drips on the ground under the air
conditioner drain while the system is working and
even after you have stopped the vehicle.

Under normal conditions, your vehicle's climate
control system should be left in any position other
than MAX A/C or OFF when the vehicle is parked.
This allows the vehicle to ªbreatheº through the
outside air inlet duct. In snowy or dirty conditions,
leave the mode selector in the OFF position when
the ignition is turned off.
²MAX A/C-Uses recirculated air to cool the vehicle.
MAX A/C is noisier than NORM A/C but more
economical and will cool the inside of the vehicle
faster. Airflow will be from the instrument panel
registers. This mode can also be used to reduce
undesirable odors from entering the vehicle.
²NORM A/C-Uses outside air to cool the vehicle. It
is quieter than MAX A/C but not as economical.
Airflow will be from the instrument panel
registers.
²VENT-Distributes outside air through the
instrument panel registers. However, the air will
not be cooled below the outside temperature
because the air conditioning does not operate in
this mode.
²OFF-Outside air is shut out and the fan will not
operate. For short periods of time only, use this
mode to prevent undesirable odors from entering
the vehicle.
²FLR-Allows for maximum heating by distributing
outside air through the floor ducts. However, the
air will not be cooled below the outside
temperature because the air conditioning does not
operate in this mode.
²MIX-Distributes outside air through the
windshield defroster ducts and the floor ducts.
Heating and air conditioning capabilities are
provided in this mode. For added customer
comfort, when the temperature control knob is
anywhere in between the full hot and full cold
positions, the air distributed through the floor
ducts will be slightly warmer than the air sent to

the windshield defroster ducts. If the temperature
is about 10ÉC (50ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce
fogging.

-Distributes outside air through the
windshield defroster ducts. It can be used to clear
ice or fog from the windshield. If the temperature
is about 10ÉC (50ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce
fogging.
Operating tips
²In humid weather, selectbefore driving. This
will reduce your windshield from fogging. After a
few minutes, select any desired position.
²To reduce humidity buildup inside the vehicle,
don't drive with the climate control system in the
OFF position.
²Don't put objects under the front seat that will
interfere with the airflow to the back seats.
²Remove any snow,
ice or leaves from
the air intake area
(at the bottom of
the windshield).
²If your vehicle has been parked with the windows
closed during hot weather, the air conditioner will
do a much faster job of cooling if you drive for
two or three minutes with the windows open. This
will force most of the hot, stale air out of the
vehicle. Then operate your air conditioner as you
would normally.
²When placing objects on top of your instrument
panel, be careful to not place them over the
defroster outlets. These objects can block airflow
and reduce your ability to see through your
windshield. Also, avoid placing small objects on

Failure to inspect and if necessary replace
the safety belt assembly under the above
conditions could result in severe personal injuries
in the event of a collision.
Refer toCleaning and maintaining the safety
beltsin theMaintenance and caresection.
AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)
Important supplemental restraint system (SRS)
precautions
The supplemental
restraint system is
designed to work with
the safety belt to help
protect the driver and
right front passenger
from certain upper
body injuries.
Air bags DO NOT
inflate slowly or gently
and the risk of injury
from a deploying air bag is greatest close to the trim
covering the air bag module.

considerable force, there is the risk of death or
serious injuries such as fractures, facial and eye
injuries or internal injuries, particularly to occupants
who are not properly restrained or are otherwise out
of position at the time of air bag deployment. Thus,
it is extremely important that occupants be properly
restrained as far away from the air bag module as
possible while maintaining vehicle control.
Several air bag system components get hot
after inflation. Do not touch them after
inflation.
If the air bag is deployed,the air bag will
not function again and must be replaced
immediately.If the air bag is not replaced, the
unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
²driver and passenger air bag modules (which
include the inflators and air bags),
²one or more impact and safing sensors,
²a readiness light and tone
²and the electrical wiring which connects the
components.
The diagnostic module monitors its own internal
circuits and the supplemental air bag electrical
system warning (including the impact sensors), the
system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument
cluster or a tone to indicate the condition of the
system. Refer to theAir bag readinesssection in
theInstrumentationchapter. Routine maintenance
of the air bag is not required.

Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is
present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you ever smell exhaust fumes of any kind
inside your vehicle, have your dealer inspect
and fix your vehicle immediately. Do not drive if
you smell exhaust fumes. These fumes are harmful
and could kill you.
Have the exhaust and body ventilation systems
checked whenever:
²the vehicle is raised for service.
²the sound of the exhaust system changes.
²the vehicle has been damaged in a collision.
Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of California to
cause cancer, and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in
an open area for long periods of time, open the
windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped)
to bring in fresh air.
Improve vehicle
ventilation by keeping
all air inlet vents clear
of snow, leaves and
other debris.

stopping distance. Always leave enough room
between your vehicle and the vehicle in front of
you to stop.
²We recommend that you familiarize yourself with
this braking technique. However, avoid taking any
unnecessary risks.
Hydraulic brake booster system (Hydroboost)
The Hydroboost system receives fluid pressure from
the power steering pump to provide power assist
during braking.
The sound of the pump operating may be heard by
the driver, but this is a normal characteristic of the
system.
For Hydroboost-equipped vehicles operating under
normal conditions, the noise of the fluid flowing
through the booster may be heard whenever the
brake is applied. This condition is normal. Vehicle
service is not required.
If braking performance or pedal response becomes
very poor, even when the pedal is strongly
depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle
safely as soon as possible and seek service
immediately.
Parking brake
Apply the parking
brake whenever the
vehicle is parked. To
set the parking brake,
apply the brake pedal
and pull the parking
brake handle up as far
as possible.

Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
your Scheduled Maintenance guide for more
information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs
and other obstacles.
²Allow more distance for stopping with a trailer
attached.
²The trailer tongue weight should be 10% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.

Maintenance and care
130

If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel
tank may damage the fuel system or cause the fuel
system to work improperly in a collision, which
may result in possible personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
Do not use fuel containing methanol. It can damage
critical fuel system components.
Your vehicle was not designed to use fuel or fuel
additives with metallic compounds, including
manganese-based compounds containing MMT.
Repairs to correct the effects of using a fuel for
which your vehicle was not designed may not be
covered by your warranty.
Octane recommendations
Your vehicle is
designed to use
ªRegularº unleaded
gasoline with an
(R+M)/2 octane rating of 87. We do not recommend
the use of gasolines labeled as ªRegularº that are
sold with octane ratings of 86 or lower in high
altitude areas.
Do not be concerned if your engine sometimes
knocks lightly. However, if it knocks heavily under
most driving conditions while you are using fuel with
the recommended octane rating, see your dealer or
a qualified service technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting, rough idle or
hesitation driveability problems during a cold start,
try a different brand of ªRegularº unleaded gasoline.
