STARTING AND OPERATING VEHICLE
ENGINE EXHAUST GAS CAUTION
(CARBON MONOXIDE
Avoid breathing exhaust gases because they contain. 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 suspect that exhaust fumes are entering the Motor-
home, have the cause determined and corrected as soon as possible . If you
must drive under these conditions, drive with two rear windows CLOSED
and ALL other windows fully OPEN . Adjust heating or cooling system for
maximum ventilation (see below) .
Protect- against carbon monoxide entry into the vehicle body. The best
way is to keep the engine exhaust system, body and body ventilation
system properly maintained . It is recommended that the exhaust system
and body be inspected by a competent mechanic :
" Each time the vehicle is raised for oil change .
Whenever
a
change is noticed in the sound
of the
exhaust system .
Whenever the exhaust system, underbody or rear of the vehicle is
damaged.
See
your Maintenance Schedule folder for inspection procedure.
To allow proper operation of the vehicle's ventilation system, keep front
inlet grille clear of snow, leaves, or other obstructions at
all
times .
OCCUPYING A PARKED VEHICLE WITH ENGINE RUNNING FOR A LONG
TIME IS NOT RECOMMENDED.
Do not run engine in confined areas such as garages any more than
needed to move vehicle in or out of area . When vehicle is stopped in an
UNCONFINED area with the engine running for any more than a short
time, adjust heating or cooling system to force outside air into vehicle as
follows:
" Set fan to high speed, upper control lever to any position except "OFF ."
The two rear windows - s hould be closed while driving to help prevent
drawing exhaust gases into the vehicle. In addition, it is recommended
that roof vent(s) be closed while driving. If a rear window or roof vent
must remain open for some reason while moving, or if electrical wiring or
other cable connections to a trailer must pass through the seal between
them and the body, these precautions should be followed:
" Close all windows.
Adjust heating or cooling system to force outside air
into
the vehicle . . .
by setting fan to high speed and upper control
lever
to any position
except "OFF."
Fully open air vents in or under the instrument panel .
It
is
important that the engine inside access cover
be
properly seated to
prevent possible leakage of exhaust fumes
into
the vehicle through this
opening.
