FUELING
Two diesel (ULSD) fuel fillers are installed on the
coach. One is located behind a filler door in the fuel
tank compartment door on the curbside and the
second location is on the roadside behind a filler door
in the A/C condenser door (Figures 92 and 93).
Figure 92. Diesel (ULSD) Fuel Door
Figure 93. A/C Condenser Door
The fuel tank is equipped with a whistle that stops
when the tank is full. Close filler and latch it securely.
Do not fill the tank from both necks at once or
have both fill caps open; the tank will over-fill
and overflow.
DO NOT put anything but DEF in the DEF tank
( blue cap ).
One diesel exhaust fuel (DEF) filler door is next to
the curbside diesel (ULSD) filler door ().

AUXILIARY HEATER
The auxiliary heater is located in the left rear of the
engine compartment. The auxiliary heater turns on
automatically to augment the temperature of engine
coolant for coach heating.
To preheat the coolant or test the heater, turn the
auxiliary heater ON with the AUX HEAT switch.
Auxiliary Heater Diagnostics
The operator can identify function and component
diagnostics by checking the light bars or number
display located on the front of the control module.
