Operation
OFF: Turn the left knob to this position to turn the
climate control system off.
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. 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,
turning on the recirculation mode helps to prevent the
air inside the vehicle from becoming stale. After five
minutes recirculate will allow some outside air into the
vehicle.
) (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.
