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.

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
