HEATING AND AIR CONDITIONING
3
Introduction
Your vehicles heating and air
conditioning system operates in three
distinct modes; manual, automatic,
and maximum defrost. Each mode
provides the driver with the greatest
level of comfort and convenience while
maintaining the exibility of traditional
systems.
The recommended
mode for all
conditions that do not require
windshield defrosting is the automatic
mode on
page 3-83. This mode is
capable of maintaining cab comfort
under various driving conditions
without driver interaction.
The cab
heater and A/C controls are
located together in the center of the
dash just to the right of the steering
column. The sleeper heater and A/C
controls are located in the sleeper
cabinet.
WARNING!
Do not drive with visibility reduced
by fog, condensation, or frost on the
windshield. Your view may be ob
-
scured, which may result in death,
personal injury, equipment or prop
-
erty damage. For clear visibility and
safe driving it is extremely important
for you to follow the instructions per
-
taining to the function and use of the
ventilation/heating and defogging/de
-
frosting system. If in doubt, consult
your dealer. Maximum heating output
and fast defrosting can be obtained
only after the engine has reached op
-
erating temperature.
WARNING!
Exhaust fumes from the engine con-
tain carbon monoxide, a colorless and
odorless gas. Do not breathe the
engine exhaust gas. A poorly main
-
tained, damaged or corroded exhaust
system can allow carbon monoxide to
enter the cab. Entry of carbon monox
-
ide into the cab is also possible from
other vehicles nearby. Failure to prop
-
erly maintain your vehicle could cause
carbon monoxide to enter the cab,
resulting in death or personal injury.
