Note:
Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats.
Note: Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.
Manual Climate Control
Note: To reduce fogging of the windshield
during humid weather, adjust the air
distribution control to the windshield air
vents position. Automatic Climate Control
Note:
Adjusting the settings when your
vehicle interior is extremely hot or cold is
not necessary. The system automatically
adjusts to heat or cool the interior to your
selected temperature as quickly as possible.
For the system to function efficiently, the
instrument panel and side air vents should
be fully open.
Note: If you select AUTO during cold
temperatures, the system directs airflow to
the windshield and side window vents. In
addition, the fan may run at a slower speed
until the engine warms up.
Note: If you select
AUTO during hot
temperatures and the inside of the vehicle
is hot, the system automatically uses
recirculated air to maximize interior cooling.
Fan speed may also reduce until the air
cools.

Your vehicle is equipped with a cabin air
filter, which gives you and your passengers
the following benefits:
•
It improves your driving comfort by
reducing particle concentration.
• It improves the interior compartment
cleanliness.
• It protects the climate control
components from particle deposits.
You can locate the cabin air filter behind
the glove box.
Note: Make sure you have a cabin air filter
installed at all times. This prevents foreign
objects from entering the system. Running
the system without a filter in place could
result in degradation or damage to the
system.
Replace the filter at regular intervals. See
Scheduled Maintenance
(page 581).
For additional cabin air filter information,
or to replace the filter, see an authorized
dealer.
