Mountain driving or desert temperatures can put ex-
treme demands on chassis components. Under ex-
treme use conditions you may need to turn off the
vehicle air conditioner to improve engine and transmis-
sion cooling.
Be aware of the extra height of your motor home. Check
for low hanging tree branches or other obstructions
whenever you drive or park. Avoid low overhangs when
pulling in for service. Always check overhead clear-
ances of overpasses and bridges. This may be particu-
larly important if you drive with the overhead vents open
or if, the motor home is equipped with a roof air condi-
tioner, roof rack, CB orTV/radlo,antenna. aefore leaving
on a trip, check your route. Some tunnels prohibit motor
homes with LP gas systems.
When parking parallel to a curb, be sure to allow for
poles or obstructions as the front and rear portions of the
motor home swing wider than an automobile. When
parking on an incline, turn the front wheels into the curb
in the direction of the roll to aid the parking brake. When
parking, always shift the transmission to PARK ("P") and
set the parking brake, if applicable.
WARNING
DO NOT PARK OR IDLE THE MOTOR HOME
OVER COMBUSTIBLE MATERIALS SUCH
AS TALL GRASS OR DRIED LEAVES. THIS
IS PARTICULARLY IMPORTANT IFTHE EX-
HAUST SYSTEM HAS NOT BEEN PROP-
ERLY MAINTAINED. COMBUStiBLE MATE-
RIALS MAY CATCH FIRE FROM THE HOT
EXHAUST GASES, SOOT OR SPARKSTHAT
COULD ESCAPE THROUGH CORROSION
HOLES OR CRACKS.
If operating, parking or idling your vehicle off-road is
unavoidable:
Be aware thai c.ombustible materials could catch fire
from the vehicle'sho't exhaust system.
Avoid driving your vehicle through or over combustible
materials such as leaves, grass, vegetation or stubble
high enough to touch, catch or collect on its hot exhaust
system.
Parking or idling should be done only in an area where
there are no combustible materials under the vehicle.
FUEL AND FUEL SYSTEMS
See the Chassis Operator's Manual in the Owner's
Information Package for chassis fuel recommendations.
If your motor home is equipped with a generator, see the
generator operating instructions in the Owner's Informa-
tion Package for fuel and maintenance recommenda-
tions.
Fuel Fill
The fuel filler cap is located toward the rear of the coach.
Modern fuel systems may build up vapor pressure within
the tank as the gasoline warms during use or hot weather.
Under certain conditions, sudden release of this pressure
when removing ,the gasoline cap can cause gasoline to
spray from the fill opening, creating a fire hazard.
WARNING
WHEN REMOVING THE GASOLINE CAP, RO-
TATE SLOWLY ONLY FAR ENOUGH TO AL-
LOWPRESSURETO RELEASE. AFTER "HISS-
ING" SOUND STOPS, COMPLETE THE RE-
MOVAL OFTHE CAP.
To protect the gaSOline system from excessive pressure
or vacuum, or from sudden release of pressure, replace
lost or damaged caps with caps of the same design which
are available from your Fleetwooq ITiotqr
.~qrne
dealer.
Clean up fuel spills immediately. Raw fuel spilled on the
motor home could .damage the exterior finish, and is a
serious fire hazard.
Fuel Types And Vapor Lock
Your motor hOme's automotive fuel and emissions sys-
tems are sophisticated and highly engineered to meet
Federal and State emissions standards. They are some-
times sensitive to fuel types and blends, particularly fuels
blended for certain altitudes'and climates. Fuel suppliers
provide customers with the correct fuel for their location
and seasonal conditions. Sometimes, though, fuel blended
for winter is supplied during summer months.
~
''Vapor lock" occurs when gasoline vaporizes, and vapor
pockets block the flow of liquid fuel to the engine. If you
experience engine stall or stutter, you may be experienc-
ing vapor lock. If your engine and fuel system are properly
tuned and maintained, you should not experience this
problem. If vapor lock occurs, the fuel itself could be the
cause. If at. all possible; check with the service station
operator as tothe fuel blend before filling your fuel tank. If
you purchase your fueLfrom nationally recognized fuel
dealers, your chances of vapor lock can be reduced. If you
store your motor home during the winter months, be aware
that when you take the vehicle out of storage in the spring
or summer, winter fuel may cause vapor lock until it is
consumed.
