5. Fuel Gauge: The fuel gauge will register the approximate fuel
level in the tank when the ignition switch is in the run position.
NOTE: Fuel mileage varies with driving style and road con-
ditions. Always average more than one tankful to obtain a
more accurate figure.
6. Engine Coolant Temperature Gauge: Under average conditions,
the gauge will read between 160º F and 212º F. Monitor this
gauge frequently when climbing hills, towing, or in high ambient
temperatures. Overheating may be a result of any of the following
conditions:
• Low coolant level.
• Fan failure.
• Mechanical failure of the hoses or belts.
• Blockage of the charge air cooler fins.
• Climbing a long hill on a hot day.
• Towing a heavy trailer.
• Idling for long periods of time.
7. Engine Oil Pressure Gauge: Indicates the pressure of the oil and
not the amount of oil in the system. Normal ranges are between 15
psi and 60 psi.
8. Headlight Switch: Pull one click to operate the parking lights. Pull
two clicks to operate the headlights. Rotating the headlight switch
clockwise will dim the dash lights. Counterclockwise rotation will
illuminate the map light in the overhead compartment.
Daytime Headlight System/CSA Standard: The Hamsar Daytime
Running Light (DRL) module is a solid-state component that is
installed on all CSA (Canadian Standard Approved) motorhomes.
The daytime running light module operates only the low beam ele-
ments at 50% of their normal rated voltage to prolong bulb life.
The module activates the headlights low beam when the ignition
key is turned on and the park brake is released. Tailights and clear-
ance lights are not illuminated when the DRL module is activated.
The headlight switch will deactivate the DRL module resuming
normal headlight/taillight operation.
9. Wiper/Washer Switch: This is a multi-function switch, which
controls the speed and delay of the wiper motor. Push the control
