first available opportunity.
Under engine misfire
conditions, excessive
exhaust temperatures could
damage the catalytic converter,
the fuel system, interior floor
coverings or other vehicle
components, possibly causing a
fire.
Fuel reset
Illuminates when the ignition key
is turned to the ON position and
the fuel pump shut-off switch has
been triggered. For more
information, refer toFuel pump
shut-off switchin theRoadside
emergencieschapter.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to
flash or remains on, have the
system serviced immediately.
Safety belt
Momentarily illuminates when the
ignition is turned ON to remind
you to fasten your safety belts. For
more information, refer to the

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
and. However, the air
conditioning will only function if
the outside temperature is about
10ÉC (50ÉF) or above.
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.
²MAX A/C-Uses recirculated air
to cool the vehicle. MAX A/C is
noisier than 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
prevent undesirable odors from
entering the vehicle.
²A/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.
²
(Vent)-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.

²(Panel and
floor)-Distributes outside air
through the instrument panel
registers 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
instrument panel registers.
²
(Floor)-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.
²
(Floor and
defrost)-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

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 prevent
fogging.
²
-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 prevent
fogging.
Operating tips
²In humid weather, select
before driving. This will
prevent your windshield from
fogging. After a few minutes,
select any desired position.
²To prevent 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.
Controls and features
21

²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield under
the hood).
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
top of your instrument panel.
These objects can fall down into
the defroster outlets and block
airflow and possibly damage
your climate control system.

Safety belt assemblies not in use
during a collision should also be
inspected and replaced if either
damage or improper operation is
noted.
Failure to 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

If the air bag is inflated,
the air bag will not
function again and must be
replaced immediately.Ifthe
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 the
Instrumentationchapter. Routine
maintenance of the air bag is not
required.
