Mercury 2000 Grand Marquis - Manual (Page 27)

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.
• MAX 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 prevent undesirable odors from entering the
vehicle.
• NORM 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.
• 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.
• OFF-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.
• FLR-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.
• MIX-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 10°C (50°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
• DEF
-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 10°C (50°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
Operating tips
• In humid weather, select
before driving. This will reduce fogging
on your windshield. After a few minutes, select any desired position.
