Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool
-down on very hot days, use MAX with
the temperature levers all the way in the blue area. If
this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature levers in the blue area. The system will
bring in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI
-LEV and set the temperature levers to a
comfortable setting. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than at
others. Push the A/C button on for cooling.
Dual Automatic ComforTemp
Climate
Control (If Equipped)
With this system, you set a temperature. You can then
either let the system automatically control airflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best if you
keep your windows closed while using it.

Passenger's Temperature Control
The PASSENGER CONTROL buttons with the arrows
adjust the temperature on the passenger's side so that it
is warmer or cooler than the temperature for the driver's
side. Push the DUAL button so that the indicator light is
lit. Press the right arrow button to raise the temperature.
Press the left arrow button to lower the temperature. The
display will not show the passenger's temperature, only
that of the driver. Indicators in the passenger control
section will show passenger's side temperature relative
to the driver's set temperature.

The amber light indicates the same temperature as
set for the driver.

The red lights indicate a warmer temperature than
that of the driver.

The blue lights indicate a cooler temperature than
that of the driver.
Hot Weather Example: When you start the vehicle in
hot weather, 80F (27C) or after being parked during the
day in full sun, if your driver set temperature is 75F
(24C) and you are in full automatic mode, the system
will automatically move the temperature to full cold. The fan will be at low speed momentarily and then go to
the high speed. The air intake will be recirculated for
maximum cooling performance. As the interior of the
vehicle cools down to your desired comfort point, the fan
speed will decrease and the temperature will move to a
warmer position to maintain your desired comfort. As the
interior cools down or the sun load decreases the system
could switch to air delivered to A/C vents and the floor.
Cold Weather Example: When you start the vehicle in
cold weather, (below freezing) or after being parked
overnight. If your Driver Set Temperature is 75F
(24C) and you are in Full Automatic mode, the system
will automatically move the temperature doors to full
hot. The fan will start out at a low speed and will
increase to a higher speed as the engine warms up. The
air will be delivered to the floor. As the the interior of
the vehicle warms up to your desired comfort point, the
fan speed will decrease and the temperature will move
to a cooler position to maintain your desired comfort. As
the cabin warms up or the sun load increases the system
could switch to air delivered to the windshield and the
floor (DEFOG mode).
