AUTO: Press to switch on automatic operation. Adjust to select the desired
temperature. Fan speed, air distribution, air conditioning operation, and outside
or recirculated air are automatically adjusted to heat or cool the vehicle to
maintain the desired temperature. You can also switch off dual zone mode by
pressing and holding for more than two seconds.

A

MAX Defrost: Press to switch on defrost. Outside air flows through the
windshield vents, air conditioning automatically turns on, and fan automatically
adjusts to the highest speed. You can also use this setting to defrost and clear
the windshield of a thin covering of ice. The heated rear window also
automatically turns on when you select maximum defrost.

B

Note: To prevent window fogging, you cannot select recirculated air when
maximum defrost is on.

Power: Press to switch the system on and off. When the system is off, it
prevents outside air from entering the vehicle.

C

Air distribution control: Press to switch airflow from the windshield,
instrument panel, or footwell vents on or off. You can distribute air through any
combination of these vents.

D

Recirculated air: Press to switch between outside air and recirculated air. The
air currently in the passenger compartment recirculates. This can reduce the
time needed to cool the interior and reduce unwanted odors from entering your
vehicle.

E

Note: Recirculated air may also turn on and off automatically in instrument
panel or instrument panel and floor airflow modes during hot weather to improve
cooling efficiency.

MAX A/C: Press for maximum cooling. Recirculated air flows through the
instrument panel vents, air conditioning automatically turns on, and the fan
automatically adjusts to the highest speed.

F

DUAL: Press to switch separate passenger side temperature control off and
on. When dual zone is off, passenger temperature settings remain the same as
the driver settings.

G

Passenger temperature control: Adjust the temperature setting on the
passenger side.

H

A/C: Press to switch the air conditioning on or off. Air conditioning cools your
vehicle using outside air. 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.

I

Note: In certain conditions (for example, maximum defrost), the air conditioning
may continue to operate even though the air conditioning is switched off.

Heated seats: Press to switch the heated seats on and off. See Heated Seats
(page 160).

HINTS ON CONTROLLING THE
INTERIOR CLIMATE

General Hints

WARNING

Prolonged use of recirculated air may
cause the windows to fog up. If the
windows fog up, follow the settings

for demisting the windshield.

Note: You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting.

Note: To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.

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
outside 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 outside
temperatures, or when the inside of the
vehicle is hot, the system automatically uses
recirculated air to maximize interior cooling.
When the interior reaches the selected
temperature, the system automatically
switches to using outside air.
