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 should overheat, as indicat-
ed by the engine coolant temperature
light, 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 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 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.
NOTE
Keep the engine exhaust system and
the vehicles cab ventilation system
properly maintained. It is recommend-
ed that the vehicles 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 (3) Whenever the exhaust sys-
tem, underbody, 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.
