Climate Controls

Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Manual Operation
To change the current mode, select one of the following
settings on the right knob.
MAX (Maximum Air-Conditioning): This mode
recirculates much of the air inside your vehicle and
sends it through the instrument panel outlets. The
air-conditioning compressor will run automatically in this
setting unless the outside temperature is below
40°F (4°C).
VENT (Ventilation): This mode brings in outside air
direct and directs it through the instrument panel outlet.
BI-LEV (Bi-Level): This mode directs approximately
half of the air to the instrument panel outlets, and then
directs most of the remaining air to the floor outlets.
Some air may be directed toward the windshield.
HTR (Heater): This mode directs most of the air to the
floor outlets, with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
BLEND: This mode directs half of the air to go to the
floor outlets and half to the defroster and side window
outlets. The air-conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40°F (4°C).
The right knob can also be used for the defrost mode.
Information on defrosting and defogging can be
found later in this section.
