NOTE
Under most circumstances, idling your
engine
for long periods merely wastes
fuel. In severe arctic weather condi-
tions, however, you may need longer
idling to be sure all parts of your en-
gine are fully lubricated.
WARNING
Exhaust fumes from the engine con-
tain
carbon monoxide, a colorless and
odorless gas. DO NOT breathe the en-
gine exhaust gas. A poorly maintained,
damaged, or corroded exhaust system
can allow carbon monoxide to enter
the cab. Entry of carbon monoxide into
the cab is also possible from other ve-
hicles nearby. Failure to properly main-
tain your vehicle could cause carbon
monoxide to enter the cab, resulting in
personal injury or death.
WARNING
Never idle your vehicle for prolonged
periods
of time if you sense that ex-
haust fumes are entering the cab. In-
vestigate
the cause of the fumes and
correct it as soon as possible. If the
vehicle must be driven under these
conditions, drive only with the windows
open. Failure to repair the source of
the exhaust fumes may result in death,
personal injury, equipment or property
damage.
WARNING
To reduce the chance of personal in-
jury
, vehicle damage, and/or death
from overheated engines, which can
result in a fire, never leave the engine
idling without an alert driver present. If
the engine does overheat, as indicated
by the engine coolant temperature
lamp, immediate action is required to
correct the condition. Continued unat-
tended operation of the engine, even
for a short time, may result in serious
engine damage or a fire. Failure to
comply may result in death, personal
injury, equipment or property damage.
CAUTION
The use of a winterfront can result in
excessive
coolant, engine oil, and in-
take air temperatures, which may lead
to overheating and possible engine
damage.
CAUTION
DO NOT allow your engine to idle, at
low
rpm (400-600 rpm), longer than
five minutes. Long periods of idling af-
ter the engine has reached operating
temperatures can decrease engine
temperature and cause gummed pis-
ton rings, clogged injectors, and possi-
ble engine damage from lack of lubri-
cation. The normal torsional vibrations
generated can also cause transmis-
sion wear.
