Regional Haul Model Operator's Manual - Peterbilt Motors Company

CONTROLS AND DISPLAY
CIGARETTE LIGHTER
For Efficient Cooling:
1. Be sure all heater - air conditioner controls are off.
2. Start the engine. Allow time for warm-up.
CAUTION: A cold compressor can cause
refrigerant to liquefy and warp the valve
plates or cause a hydraulic lock. Warm the
engine before starting the air conditioner.
CAUTION: To avoid damage to the compressor
& blower motors, turn off all controls
when a system is not in use.
3. Set the air control in the RECIRC mode.
4. Close all windows.
5. Idle the engine between 1000 and 1500 RPM and
turn the blower speed control to High.
6. After the cab temperature cools to a comfortable
level, adjust the blower speed and controls to keep
the desired condition.
NOTE: When the air conditioner is not in regular
use, operate it for at least 15 minutes at least
once a month or every 5,000 miles (8,000 Km),
whichever comes first. This will lubricate the
seals in the air conditioning system. The air conditioning
system is active when the Defrost mode
is selected.
Cigarette Lighter
02912A
The cigarette lighter is located at the bottom of the cup
holders. To operate your lighter, push the center of the
knob in. After a few moments the lighter will automatically
pop out, ready to use. After use, insert the knob, but do
not push it in. The cigarette lighter circuit is protected by a
10-ampere fuse to prevent damage should the lighter get
stuck in the IN position. If this fuse needs replacement,
check to ensure that the lighter is not stuck before replacing
the fuse.
WARNING! Do not exceed the voltage/amperage
capacity of the cigarette lighter. It could
result in a fire causing death or personal
injury. Follow all warnings and instructions in
the operator's manual for the appliance you
are using.
