To provide you with maximum comfort in the Automatic
mode, during cold start-ups the blower fan will remain

increase in speed and transition into Auto mode.
Manual Operation Override
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation con-
trol.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode. The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:
Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
364 UNDERSTANDING YOUR INSTRUMENT PANEL

OAT coolant (conforming to MS.90032) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in
fresh air with the blower setting in high. This will ensureadequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold weather. To clear
the windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the Recirculation
mode without A/C for long periods, as fogging may
occur.
NOTE:
Automatic Temperature Controls (ATC) will au-
tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
