Controls and features
PNL FLR-Distributes outside air through the instrument panel
registers and the floor ducts. Heating and air conditioning capabilities
are provided in this mode. The air will be heated or cooled based on
the temperature selection. For added customer comfort, the air
distributed through the floor ducts will be slightly warmer than the air
sent to the instrument panel registers.
FLOOR-Allows for maximum heating by distributing outside air
through the floor ducts. However, the air cannot be cooled below the
outside temperature because the air conditioning does not operate in
this mode.
FLR DEF-Distributes outside air through the windshield defroster
ducts and the floor ducts. Heating and air conditioning capabilities are
provided in this mode. The air will be heated or cooled based on the
temperature selection. For added customer comfort, 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 prevent fogging.
DEF -Distributes outside air through the windshield defroster
ducts. It can be used to clear ice or fog from the windshield. If the
outside air temperature is about 10°C (50°F) or higher, the air
conditioner will automatically dehumidify the air to prevent fogging.
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
