MANUAL CLIMATE CONTROL

(If Equipped)

E217902

Fan speed control: Adjusts the volume of air circulated in the vehicle.

A

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

B

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

C

Note: At least one of these buttons remain on while the system is on.

Recirculated air: Press to switch between outside air and recirculated air. The
air currently in the passenger compartment recirculates. This may reduce the
time needed to cool the interior (when used with A/C) and reduce unwanted
odors from entering your vehicle.

D

Note: Recirculated air may turn off (or prevent you from switching on) in all air
flow modes except MAX A/C to reduce the risk of fogging. Recirculation may
also turn on and off in Panel or Panel/Floor air flow modes during hot weather
in order to improve cooling efficiency.

Temperature control: Adjusts the temperature of the air circulated in your
vehicle.

E

MAX Defrost: Turn to the right to switch on defrost. Air flows through the
windshield vents and the fan adjusts to the highest speed. You can also use
this setting to defog and clear the windshield of a thin covering of ice. The heated
rear window also turns on when you select maximum defrost.

F

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

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

G

A/C: Press to switch the air conditioning on or off. Use A/C with recirculated
air to improve cooling performance and efficiency.

H

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

Heated seats: Press to switch the heated seats on and off. See Heated Seats
(page 164).

I

Heated exterior mirrors: Press to switch the heated exterior mirrors on and
off.
