STARTING AND OPERATING
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 unconsciousness 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.
Prevent carbon monoxide from entering the cab. The best way is
to keep the engine exhaust system, cab and cab ventilation system
properly maintained.
We recommend that the exhaust system and cab be inspected by
a competent technician:
•
Each time the vehicle has an oil change.
•
Whenever a change is noticed in the sound of the exhaust system.
•
Whenever the exhaust system, underbody or cab is damaged or
becomes corroded.
See “Maintenance Schedule” in Section 5 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.
Do not park with the engine running or idle this vehicle for more than
10 minutes with the ventilation system control switch in the “OFF”
position. Even with the ventilation system on, running the engine while
parked or stopped for longer periods of time is not recommended. Entry
of carbon monoxide into the cab is possible with a poorly repaired,
damaged, or corroded exhaust system or cab.
Do not run the engine in confined areas (such as garages or next to a
building) any more than needed to move the vehicle. When the vehicle
has to be stopped in an unconfined area with the engine running for any
more than a few minutes, take the following steps:
A. Adjust the heating or cooling system to force outside air into
the cab. With temperature and select levers in any position:
•
Set the air source lever to the fresh air position.
•
Set the fan blower to the “3” or “4” position.
•
See “Heating and Ventilation System Controls” later in this
section of the manual.
B. Keep the exhaust tailpipe area clear of snow and other material
to help reduce the buildup of exhaust gases under the vehicle.
This is particularly important when parked in blizzard conditions.
