On sunny days, when the air is moderately warm or
cool, use Bi
-
Level to deliver warm air to the floor ducts
and cooler air to the instrument panel outlets. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when Recirculation is selected. This is helpful when you
are trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic ComforTemp
t
system and it is set for Automatic Operation, on very hot
days, the system will automatically enter recirculation
mode and the temperature door will be positioned at the
full cold position for maximum cooling. If the system is
not in the automatic mode, recirculation should be
selected to provide maximum cooling. You can choose
the extreme comfort setting of 60
_F (16_C), but the
system will not cool any faster as a result.
Heating
If your vehicle has the electronic touch system, on cold
days, use HTR with the TEMPERATURE lever toward
WARM and the fan speed toward HIGH.
If your vehicle has the Dual Automatic ComforTemp
system, and on cold days, if the automatic mode is
selected, the system will automatically direct the air
toward the floor and the temperature door will be
positioned at the full hot position. You can choose the
extreme comfort setting of 90
_F (32_C) but the
system will not warm up any faster as a result. If the
outside temperature is cold, the fan will be delayed to
avoid blowing cold air. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn off
the automatic mode and return the system to
manual operation.
With each system, outside air will be brought in and sent
through the floor ducts. The heater works best if you
keep your windows closed while using it.
