Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
To change the current mode, select one of the following:

MAX: This mode is used for maximum cooling. It
will recirculate much of the air inside your vehicle.
It maximizes your air conditioner’s performance and your
vehicle’s fuel economy. The air-conditioning compressor
will run automatically in this mode when it is needed
to help dry the air in the vehicle.
H
(Vent): This mode directs air to the instrument
panel outlets.
)
(Bi-Level): This mode directs half of the air to the
instrument panel outlets, then directs most of the
remaining air to the floor outlets with some air directed
at the side windows.
A (Floor): This mode directs most of the air to the
floor outlets with some air directed to the side windows.
The right knob can also be used to select defog or

counterclockwise to increase or decrease the fan speed.
Temperature Control: Turn the center knob clockwise
or counterclockwise to manually increase or decrease
the temperature inside your vehicle.
When it’s cold outside 0°F (
−
18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
see Engine Coolant Heater on page 2-22.
