could create fogging on the inside of the
windshield. The A/C (Air Conditioning) can be
deselected manually without disturbing the mode
control selection. Continuous use of the
Recirculation mode may make the inside air stuffy
and window fogging may occur. Extended use of
this mode is not recommended. On systems with
Manual Climate Controls, the Recirculation mode
(if equipped) is not allowed in Defrost mode to

down or side to side to regulate airflow direction.
There is a shut-off wheel located below the air
vanes to shut off or adjust the amount of airflow
from these outlets.
Bi-Level Mode
Air comes from the instrument panel
outlets and floor outlets. A slight amount
of air is directed through the defrost and
side window demister outlets.

equipped.
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 Ú page 382.
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 Úpage 373.
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 (Air Conditioning)
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 plenum, they
could plug the water drains. In Winter months,
make sure the air intake is clear of ice, slush, and
snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed
