Manual override controls

The override controls are located at
the bottom of the EATC and allow
you to determine where airflow is
directed. To return to full automatic
control, press AUTOMATIC.
The air conditioning compressor will operate in all modes except FLOOR
and VENT. It will also operate only when required when AUTOMATIC
has been selected. However, the air conditioning will only function if the
outside temperature is about 10°C (50°F) 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 "breathe" through the outside air inlet
duct.
MAX A/C-Uses recirculated air to cool the vehicle. The temperature
will display 16°C (60°F). To exit, press AUTOMATIC or any other
override controls. MAX A/C is noisier than normal A/C but more
economical and will cool the inside of the vehicle faster. Airflow is
from the instrument panel registers. This mode can also be used to
prevent undesirable odors from entering the vehicle.
VENT-Distributes outside air through the instrument panel registers.
However, the air cannot be cooled below the outside temperature
because the air conditioning does not operate in this mode.
