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 en-
gine idling without an alert driver
present. If the engine should over-
heat, as indicated by the engine
coolant temperature light, immediate
action is required to correct the con-
dition. Continued unattended opera-
tion 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 engine coolant, oil, and
charge air (intake) temperatures,
which can lead to overheating and
possible engine damage.
CAUTION
Do not allow your engine to idle, at
low rpm's (400–600 rpm), longer
than five minutes. Long periods of
idling after the engine has reached
operating temperatures can de-
crease engine temperature and
cause gummed piston rings, clog-
ged injectors, and possible engine
damage from lack of lubrication. The
normal torsional vibrations generat-
ed can also cause transmission
wear.
NOTE
Keep the engine exhaust system
and the vehicles cab ventilation sys-
tem properly maintained. It is recom-
mended that the vehicles exhaust
system and cab be inspected (1) By
a competent technician every
15,000 miles (24,140 km) (2) When-
ever a change is noticed in the
sound of the exhaust system (3)
Whenever the exhaust system, un-
derbody, or cab is damaged.
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.
How to Warm Up the Transmission
In cold weather (below 32°F (0°C), you
may find shifting sluggish when you first
start up. Transmission warm-up is
especially important at this time, but it is
always a good idea to warm-up your
transmission before starting out on the
road.
To warm-up the transmission lubricating oil
during engine warm-up, with a single
transmission (manual and automatic):
1. Put the transmission in Neutral.
2. Release the clutch pedal (manual
only) and operate the transmission
in neutral for 3 to 5 minutes prior to
operating the transmission in either
forward or reverse range.
3. If you have a two-transmission
combination:
a. Put the main transmission in
gear.
b. Put the auxiliary transmission
in Neutral. This will allow the
transmission countershaft to
turn, agitating the oil and
warming it.
