OPERATING TIPS
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and the proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation
mode during Winter months is not
recommended, because it may cause window
fogging.
Vacation/Storage
For information on maintaining the Climate
Control system when the vehicle is being stored
for an extended period of time, see
Ú
page 461.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid 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.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions,
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter the
air distribution box, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
