Another note on long storage - if you plan to store
your motor home for a long period in conditions of widely
varying humidity. consider topping off the fuel tank. This
will reduce the buildup of condensation in the tank that
could cause rough engine operation, fuel filter blockage,
or other problems associated with water in the fuel.
Alternative Fuel Types
Gasohol, a mixture of ethanol (grain alcohol), or
methanol and gasoline may be used iri your motor home
engine without voiding the warranty. However, DO NOT
UNDER ANY CIRCUMSTANCES USE FUEL BLENDS
CONTAINING MORE THAN 5% METHANOL OR 10%
ETHANOL, AND DO NOT USE BLENDS THAT CONTAIN
BOTH METHANOL AND ETHANOL. Any fuel blend you
use containing alcohol must also contain cosolvents and
other additives to protect the fuel system components.
If you are not sure of the composition of the
alcohol/gasoline blend you intend to use, ask your ser-
vice station operator. Discontinue use of any
alcohol/gasoline blend if driveability or fuel system
problems occur.
Chemical reactions between the fuel components and
the materials in the fuel lines can cause deterioration
of the fuel lines during storage periods. These effects
are especially noticeable with gasohol blends. If you plan
to use alcohol blended fuel, and expect to store your
motor home for periods of 60 days or more, add a fuel
additive that is formulated to counteract these oxida-
tion effects. Your dealer can advise you on the proper
additives and their use.
If gasohol is spilled on a painted surface, some dull-
ing or softening of the paint may result.
Overheating
Operate and service the engine and cooling systems
in your vehicle as recommended in the Chassis
Operator's Manual.
Variable Speed Engine Fan
Your motor home engine is equipped with a variable
speed fan clutch. When the -engine is under load or re-
quires maximum cooling, the fan adjusts and turns faster.
The fan may become very noisy at high speed and when
maximum cooling is required. When the engine doesn't
need maximum cooling, the fan just idles along. This
conserves fuel and the fan is less noisy.
High speed fan noise can sometimes be misinterpreted
as transmission slippage. This is not the case. When
the engine is hot and requires extra cooling, the fan turns
at full speed. High engine speed and temperature con-
ditions; such CIs pulling away from a _ stop after long
freeway driving, can cause loud fan noise until the engine
cools down. This fan noise indicates that the fan is do-
ing what it is supposed to do. This noise is not a defect
in the fan or the transmission.

ENGINE EXHAUST SYSTEM COMPONENT HEAT
Your motor home engine has been designed to con-
form with Federal and State emission requirements. To
meet these requirements, engine operating temperatures
are, high. As a result, the engine and exhaust system
components radiate a great deal of heat. Parts of the
exhaust system may operate at temperatures near 700
degrees F. These temperatures are normal for your
vehicle.
Special heat shields may be built into your vehicle
to protect wiring or other components from possible
heat damage caused by the exhaust system. Do not
modify or remove these shields without consulting your
RV dealer. If you want to install equipment, add wiring,
plumbing, or other components near the exhaust system
or the heat shields, do so only after you thoroughly in-
vestigate and understand how the equipment will be
affected by the heat radiated by the exhaust system.
CARBON MONOXIDE SAFETY PRECAUTIONS
Carbon monoxide is a colorless, tasteless, odorless
gas. It is a by-product of combustion in engine(s). The
engines in your motor home and generator system (if
installed) produce it constantly while they are running.
CARBON MONOXIDE, IS DEADLY. Please read and
understand the following precautions to protect yourself
and others from the effects of carbon monoxide
poisoning.
WARNING: EXHAUST GASES ARE DEADLY. DO
NOT BLOCK THE TAILPIPES OR SITUATE THE
VEHICLE IN A PLACE WHERE THE EXHAUST
GASES HAVE ANY POSSIBILITY OF ACCUMULAT-
ING OUTSIDE, UNDERNEATH, OR INSIDE YOUR
VEHICLE OR ANY NEARBY VEHICLES. OUTSIDE
AIR MOVEMENTS CAN CARRY EXHAUST GASES
INSID,E THE VEHICLE THROUGH WINDOWS OR
UfHER OPENINGS REMUfE FROM THE EXHAUST
OUTLET. OPERATE THE ENGINE(S) ONLY WHEN
SAFE DISPERSION OF EXHAUST GASES CAN BE
ASSURED, AND MONITOR OUTSIDE CONDITIONS
TO BE SURE THAT EXHAUST CONTINUES TO BE
DISPERSED SAFELY.
Beware of exhaust gas (carbon monoxide) poisoning
symptoms:
Dizziness
Intense Headache
Weakness and Sleepiness
Vomiting
Muscular Twitching
Throbbing in Temples
If symptoms indicate the possibility of carbon monox-
ide poisoning, turn off the engine(s) immediately, _ get
out into fresn air at once, and summon medical
assistance.
WARNING: DO NUf UNDER ANY, CIRCUM-
STANCES OPERATE ANY ENGINE WHILE
SLEEPING.
