ENGINE OPERATION
Engine Exhaust Gas Caution
(Carbon Monoxide)
CAUTION:
Do not breathe exhaust gas because it contains carbon
monoxide, which by itself has no color or odor. Carbon
monoxide is a dangerous gas. It can cause unconscious-
ness and can be lethal.
If at any time you think exhaust fumes are entering the
cab, have the cause determined and corrected as soon as
possible. If you must drive under these conditions, drive
only with all windows fully open.
Protect against carbon monoxide entry into the cab. The
best way is to keep the engine exhaust system, cab and
cab ventilation system properly maintained.
We rec-
ommend that the exhaust system and cab be inspected
by competent technician:
l
Each time the vehicle has an oil change.
l
Whenever a change is noticed in the sound of the
exhaust system.
l
Whenever the exhaust system, underbody or cab is
damaged or becomes corroded.
See “Maintenance Schedule” in Section 8 of this manual
for parts requiring inspection.
To allow proper operation of your vehicle’s ventilation
system, keep the air inlet grille clear of snow, leaves or
other obstructions at all times.
