On very hot days, open the windows long enough to let
the hot air out. This reduces the time required to cool the
interior of the vehicle to a comfortable temperature. If
the system is in the automatic mode (left and right mode
knob indicator lights are on), during very hot days the
system will automatically go to the recirculation mode
and the temperature door will initially be at the full cold
position for maximum cooling. You can choose the
extreme temperature setting of 60 F (16 C), but the
system will not cool any faster by choosing this setting.
Heating
In cold weather, if the automatic mode is selected
(left and right mode knob indicator lights are on), the
system will automatically direct the airflow out of the
floor ducts and the temperature door will initially be
positioned at the full hot position. You can choose
the extreme temperature setting of 90 F (32 C),
but the system will not warm up any faster by selecting
this setting.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air into the vehicle. The length of
the delay depends on the engine coolant temperature and
the outside temperature. The fan speed will increase as
the temperature of the engine coolant rises. Turning the
right mode knob will override this delay by cancelling
the automatic fan control mode.
Defogging and Defrosting
On cool, humid days, use the defog setting to keep
the windows clear while also providing heat through
the floor ducts. Turn the left mode knob clockwise
to defrost to quickly remove fog or ice from
the windshield.
For maximum front defrost performance under extreme
icing or frosting conditions, increase the temperature
setting to 90 F (33 C) and increase the fan speed
to high.
