SECTION 3 –
DRIVING YOUR MOTORHOME
3-14
NOTE: The dash air conditioner/heater is not
designed to heat and cool the entire
interior of the motorhome, but is
intended only to provide heating and
cooling for the cab area.
A small amount of air will blow out all of
the defrost and the dash vents regardless
of the mode setting.
Further Information
See the manufacturer’s user guide provided in
your InfoCase for complete operating
instructions.
AIR HORNS
Press the Air Horn switch (located on the
driver side trim panel) to the ON (up) position -
then use the horn button on the steering wheel to
sound the air horns. The switch enables the air
horn system to work with the standard chassis
horn.
Press the Air Horn switch OFF (down) to
disable the air horns.
The air horn sound units are located behind
the front grille assembly.
FUEL SELECTION – DIESEL
ENGINE
Refer to your chassis manual for the
manufacturer's recommendations on proper fuel
selection (ULSD fuel only).
Winter Fuel Waxing and Anti-Gel
Additives
In sub-freezing temperatures, #2 diesel fuel
can form small wax crystals that become trapped
in the fuel filter and block the fuel flow to the
engine, causing it to stall out. At sub-zero
temperatures, the fuel can congeal and turn
“slushy.” If this happens, the only remedy is to
have the vehicle towed into a heated facility to
allow the fuel to warm up and become fully
liquid again.
During winter time, most truck stops and
reputable filling stations have winter blend diesel
fuels available that are less susceptible to waxing.
There are also commercially available
products (typically called anti-gel additives) to
add to diesel fuel while filling the tank to inhibit
wax formation in freezing temperatures.
Further Information
Consult your chassis manual or diesel engine
guide in your InfoCase for more information on
fuel requirements and additives.
