9(Fan): Turn the knob by this symbol, located on the

left side of the climate control panel, clockwise or

counterclockwise to increase or decrease the fan speed.

During the highest fan speed selections, the fan

speed will be temporarily reduced between the transition

to a new mode. The fan will resume the original

speed when the transition to the new mode is complete.

Temperature Control: Turn the center knob clockwise

or counterclockwise to increase or decrease the

temperature inside your vehicle.

Use the right knob to select from the following modes:

H (Vent): This mode directs outside air to the

instrument panel outlets. If driving in city traffic, and the

vehicle is stopped and idling, or the weather is hot,

switch from this mode to the recirculation mode.

To prevent the air inside the vehicle from becoming

stale, be sure to return to the vent mode periodically.

) (Bi-Level): This mode directs half of the air to the

instrument panel outlets, and the remaining air to

the ﬂoor outlets. Some air may be directed toward the

windshield. Slightly cooler air is directed to the

instrument panel outlets and warmer air is directed to

the ﬂoor outlets.

6 (Floor): This mode directs most of the air to the

ﬂoor outlets with some air directed toward the side

window outlets and a little air directed to the windshield.

In this mode, the system will automatically use outside

air. The air conditioning compressor will be engaged

unless the outside temperature is 40°F (4°C) or below.

Recirculation cannot be selected when in this mode.

You can also select modes by using the

following buttons:

h (Recirculate): Press this button to recirculate

cabin air through the vehicle. It can be used to prevent

outside air and odors from entering your vehicle or

to help heat or cool the air inside your vehicle more

quickly. An indicator light below the button will come on

in this mode. Operation in this mode during periods

of high humidity and cool outside temperatures

may result in increased window fogging. If window

fogging is experienced, select the defrost mode.
