Recirculation Modes (Panel or Bi-Level)
Select the recirculation modes when
the outside air contains smoke or
odors. This feature allows for recircu-
lation of interior air only. Air flows
through the panel outlets in this mode.
Air flows through the panel only or
through both the panel and floor vents
depending on the selected mode (panel vs bi-level).
Bi-Level
Outside air flows through the outlets located in the
instrument panel and at the floor.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.
Defrost
Outside air is primarily directed to the windshield
through the defroster outlets located at the base of the windshield, and the demister outlets located at the
edge of each side of the instrument panel.
Blower Control
The rotary knob on the left of the control
panel is the blower control. Turn the
knob clockwise to one of the four posi-
tions to obtain the blower speed you
desire. To turn the blower off, turn the
knob to the far left position.
Temperature Control
The rotary knob at the center of the
control panel controls the temperature
of the interior air. You can choose your
degree of comfort by rotating the
knob. The coldest temperature setting
is to the extreme left (blue region) and
the warmest setting is to the extreme
right (red region) of the rotation.

Circulation
The cab is designed with features to promote outside air
circulation. There are grilles in the cab back panel. These
are air exhausters that provide the means for regular
exchange of cab air.
Side window demisters direct air flow specifically to the
window glass to help prevent interior fogging of the
glass. They are located in the extreme outside upper
edges of the instrument panel. The demisters also pro-
vide extra air ducts for circulation. They are in operation
whenever the Floor, Mix or Defrost modes are in use. To
remove frost from the side windows, it is best to use the
full defrost mode.
NOTE: When you turn off the engine you may hear a
hissing sound from under the hood for a short period of
time. This is a normal condition that occurs if the air
conditioning system has been on. It is not an indication of
a problem with the air conditioning system.

Dual Zone Temperature Control
Use this control to regulate the temperature of the air
inside the passenger compartment. This is accomplished
by having separate temperature control slides for both the driver and front passenger. The blue area of the scale
indicates cooler temperatures while the red area indicates
warmer temperatures.

•When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in a electrical system
failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse contin-
ues to blow, it indicates a problem in the circuit
that must be corrected.
