Diesel Fuel and Fill
It is critical to understand the danger associated with fuel. Take time to become educated
about the properties of fuel and use it safely.

fueled by the same system used to fuel the motor home chassis engine. Consider the fuel
requirements of the generator and the Aqua Hot system (if so equipped) when making a
decision on the type of fuel to use.

Diesel engines (since 2010) require the use of DEF uid (Diesel Exhaust Fluid) to aid in
burning particulate matter in the exhaust and reduce emissions to nitrogen and water. This
DEF uid is kept in a separate heated tank and is required for the normal operation of the
diesel engine. The DEF tank is typically located in one of the exterior compartments and
will have a blue cap with “DEF” written on it. There will be a series of warnings at the dash
before running out of DEF uid. If the vehicle is allowed to run out of DEF uid, engine
power is intentionally reduced and speed will be limited to 5 MPH until the tank is re-lled.
Automotive fuels can cause serious injury or death if misused or mishandled.
If you have further questions, consult your dealer or Customer Service for
assistance.
Always shut OFF the vehicle engine while refueling.
Do not bring or store fuel or other ammable liquids inside the motor
home because a re or explosion may result.
Before refueling, extinguish all smoking materials and any open ames.
Before refueling, always turn OFF all spark producing appliances (i.e.,
water heaters, furnaces, etc.).
Do not overll the fuel tank(s). The pressure in an overlled fuel tank
may cause leakage and lead to fuel spray and/or re.
Fuel spills represent a serious re hazard, and should be cleaned up im-
mediately.
Never restart an engine or re-light any pilot lights while raw fuel is pres-
ent.

If you spill fuel on the motor home, clean it up immediately. Fuel can dull or
soften paint and damage other surfaces.
