AFFECT YOUR PERCEPTION. ALWAYS USE THE
SIDE-MOUNTED REAR VIEW MIRRORS WITH THE
VIDEO MONITOR SYSTEM.
The camera lens is exposed to road dirt and will get
dirty often. Clean the camera lens and monitor screen
with a quality glass cleaner and non-abrasive cloth or
towel.
AUTOMATIC LEVELING SYSTEM
Controls for the leveling system are located on the
cabo floor next to the driver's seat.
A detailed operating and maintenance guide is included
ill your owner's information package. Read all instruc-
tions for this system carefully before operating the
system.

FUEL AND FUEL SYSTEMS
See the Chassis Operator's Manual in the Owner's
Information Package for fuel recommendations. Since
the generator fuel supply is the same as the motor home
engine. fuel supply, consult the operating instructions
for the generator before deciding on a fuel type.
Fuel Fill
The fuel filler cap is located at 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 spray
gasoline from the fill opening, causing a possible hazard.
WARNING: WHEN REMOVING THE GASOLINE
CAP, ROTATE IT SLOWLY ONLY FAR ENOUGH TO
ALLOW. PijESSURE TO RELEASE. AFTER ANY
"HISSING" ,SOUNDS STOP, COMPLETE THE
REMOVAL OF THE CAP.
'
To protect the gasoline system from excessive pressure
or vacuum, or from sudden release of pressure, replace
lost caps with caps of the same design available from
your Fleetwood motor home dealer.

Fuel Fill
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
Today's automotive fuel and emissions systems are
sophisticated and highly engineered to meet Federal and
state emissions standards. They are also sometimes sen-
sitive to fuel types and blends, particularly blends that
are optimized for climatic conditions. Fuel refiners change
the additives in the fuel to compensate for temperature
variations during winter or summer months. This com-
pensation changes the "vapor pressure" of the fuel. This
means that the fuel vaporizes easier during the winter
than it does during the summer when higher air
temperatures help the fuel vaporize in the engine. Since
colder temperatures reduce the fuel's ability to vaporize
and burn in your engine, additives help raise the volatili-
ty of the fuel. This helps the engine start easier and
ru'n smoother during,winter months. Under the best of
conditions, the refiners supply their gas station customers
with the correct fuel for their location and seasonal con-
ditions. Sometimes though, fuel blended for winter is
supplied during summer months.
What this all means is that there is a possibility of
"vapor lock" during summer driving. This condition is
a combination of new engine design (with attendant
higher temperatures under the hood), and excessive fuel
vapo'rization caused, by the vapor pressure of the fuel
you are using. If your engine and fuel system are pro-
perly tuned and maintained, you should not experience
vapor lock. If vapor lock occurs, the fuel itself could
be the cause. If at all possible, check with the gas sta-
tion attendant as to the fuel blend before filling your
fuel tank. If you purchase your fuel from nationally
recognized fuel dealers, your chances of vapor lock can
be reduced. If you store your motor home during the
winter months, avoid storing large quantities of winter
blended fuel in the tank. When you take the vehicle out
of storage in the spring or summer, this fuel may cause
vapor lock until it is used up.
