To change the current mode, press one of the following
buttons:
H
(Vent): This mode directs air to the instrument
panel outlets.
)
(Bi-Level): This mode directs about 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.
6
(Floor): 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.
9
(Fan): The fan has five speed settings: OFF, 1, 2,
3, and 4. Slide the fan lever to OFF to turn the system off.
Outside air will still come out of the floor outlets whenever
the vehicle is moving.
A
(Recirculation): If you press this button, the air
inside the cab will be recirculated. If your vehicle has air
conditioning, using recirculation will give you maximum
cooling. This mode can also be used to keep outside air,
odors and dust from entering your vehicle.
Recirculation is not available in Defog or Defrost modes.
3-18
A/C (Air Conditioning): If your vehicle has this feature,
you can use your air conditioner by selecting one of
the mode buttons, selecting a fan speed and pressing
the A/C button.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
