STARTING AND OPERATING THE VEHICLE<br />
WARNING! Exhaust fumes from the engine<br />
contain carbon monoxide, a colorless and<br />
odorless gas. A poorly maintained, damaged,<br />
or corroded exhaust system can allow carbon<br />
monoxide to enter the cab or sleeper. Failure<br />
to properly maintain your vehicle could cause<br />
carbon monoxide to enter the cab and cause<br />
death or serious illnesses.<br />
WARNING! Never idle your vehicle for prolonged<br />
periods of time if you sense that<br />
exhaust fumes are entering the cab. Investigate<br />
the cause of the fumes and correct it as<br />
soon as possible. If the vehicle must be driven<br />
under these conditions, drive only with the<br />
windows slightly open. Failure to repair the<br />
source of the exhaust fumes may lead to<br />
death, injury or serious illness.<br />
Idling the Engine<br />
Under most circumstances, continuous idling of your<br />
engine merely wastes fuel. In severe Arctic weather conditions,<br />
however, you may need longer idling to be sure all<br />
parts of your engine are fully lubricated.<br />
IDLING THE ENGINE<br />
CAUTION: Do not allow your engine to idle, at<br />
low rpm (400–600 rpm), longer than five minutes.<br />
Long periods of idling after the engine<br />
has reached operating temperatures can<br />
decrease engine temperature and cause<br />
gummed piston rings, clogged injectors, and<br />
possible engine damage from lack of lubrication.<br />
The normal torsional vibrations generated<br />
can also cause transmission wear.<br />
• During the time it takes you to drink a cup of coffee,<br />
your engine can cool as much as 60° F (33° C) below<br />
normal operating temperature. To keep the engine<br />
warm during a short break, turn it off. Do not allow<br />
your engine to idle longer than five minutes.<br />
Engine Fan Switch (Option)<br />
Your <strong>Regional</strong> <strong>Haul</strong> vehicle may have an engine fan<br />
switch installed as an option. The switch, which is<br />
mounted on the accessory switch panel, allows you to<br />
control the engine fan manually or automatically.<br />
• With the ignition key switch ON and the fan switch in<br />
the ON position, the engine fan will be on regardless<br />
of engine temperature.<br />
