NOTE:For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates cooler
temperatures. Rotating the knob clock-
wise, into the red area, indicates
warmer temperatures.
Air Conditioning Operation

Conditioning (A/C). A LED will illu-
minate when the A/C system is

Floor Mode
Air is directed through the floor outlets with a
small amount through the defrost and side win-
dow demist outlets.
Mix Mode
Air is directed through the floor, defrost and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort,
while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use the DEFROST mode with maximum blower and warm temperature settings
for best windshield and side window defrosting.
NOTE:
The air conditioning compressor operates in MIX
and DEFROST, or a blend of these modes even if the A/C
button is not pressed. This dehumidifies the air to help
dry the windshield. To improve fuel economy, use these
modes only when necessary.
Recirculation Control
Press the Recirculation Control button to
choose between outside air intake or recircula-
tion of the air inside the vehicle. A LED will
illuminate when you are in Recirculation
mode. Only use the Recirculation mode to temporarily
block out any outside odors, smoke, or dust, and to cool
the interior rapidly upon initial start-up in very hot or
humid weather.
