WARNING
NEVER start or let the engine run in
an
enclosed, unventilated area. Ex-
haust fumes from the engine contain
carbon monoxide, a colorless and
odorless gas. Carbon monoxide can
be fatal if inhaled. Failure to comply
may result in property damage, per-
sonal 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.
NOTE
Keep the engine exhaust system and
the
vehicle's cab ventilation system
properly maintained. It is recommend-
ed that the vehicle's 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; or (3) Whenever the exhaust
system, underbody, or cab is dam-
aged.
Check Engine Oil Level
WARNING
Hot engine oil can be dangerous. You
could
be burned. Let the engine oil
cool down before changing it. Failure
to comply may result in death, person-
al injury, equipment or property dam-
age.
NOTE
It takes approximately 15 minutes for
all
the oil to run into the sump when
the engine is warm. If the level is
checked immediately after switching
off the engine, the dipstick will show a
low oil level.
1. Make sure that the vehicle frame
rail is standing on a flat and level
surface.
2.
Make sure that the vehicle is
horizontal, both lengthwise and
crosswise. Check this carefully on
a vehicle with air suspension. Note
that the engine may be inclined up
to 4 degrees, depending on the
vehicle model and wheelbase.
3. Twist the dipstick handle to unlock
it, then pull the dipstick out of the
holder.
