NOTE
Keep the engine exhaust system and
the
vehicle's cab ventilation system
properly maintained. It is recommend-
ed that the vehicle's exhaust system
and cab be inspected (1) By a compe-
tent technician every 15,000 miles
(24,140 km); (2) Whenever a change
is noticed in the sound of the exhaust
system; or (3) Whenever the exhaust
system, underbody, or cab is dam-
aged.
NOTE
If you are required to idle your vehicle
for
long periods of time, install an aux-
iliary heater or automatic idle control.
These auxiliary devices can reduce
fuel consumption and save you mon-
ey.
NOTE
If you are parked next to idling vehi-
cles,
move your vehicle or do not stay
in your vehicle for prolonged periods of
time.

The source of air entering the cab can be set to either outside air or recirculation air using the button inside the fan
speed control dial. Recirculated air is automatically selected in defrost modes.
The fan speed is adjusted by rotating the dial clockwise to increase speed or counterclockwise to decrease speed.
Setting the fan dial to "O" turns the HV
AC system off.
The button inside the temperature control dial engages the A/C compressor. When activated the indicator on the
button will illuminate. During AUT
O mode, the A/C button indicator will remain illuminated at all times even though
the compressor may be cycling.
