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 level.
If the system is in the automatic mode (AUTO
-
PUSH
knob indicator light is on), during very hot days the
system will automatically go to the RECIRC mode and
the temperature door will initially be at the full cold
position for maximum cooling. You can choose the
extreme comfort setting of 60
_F (16_C), but the
system will not cool any faster by choosing the extreme
comfort setting.
Heating
In cold weather, if the automatic mode is selected
(AUTO
-
PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will initially 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 by selecting the
extreme comfort setting.
In cold weather, the system will delay turning on the
fan to avoid blowing cold air. 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 increases. Turning the
AUTO FAN knob will override this delay by turning
off the automatic fan control mode and changing the
fan speed.
Defogging and Defrosting
On cool, humid days, use the defog setting to keep
the windows clear while also providing heat through the
lower outlets. Turn the AUTO
-
PUSH knob clockwise to
DEF 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.
