Prior to leveling:
Set park brake.
Place transmission in neutral.
Ensure front wheels are pointing straight
ahead.
Have motorhome at ride height with air
tanks full.
Turn off ignition and extend slide-outs.
Leveling Procedure:
Start the engine.
Press the POWER button on the leveling
control panel to turn the system on. The
Power indicator light will glow solid green.
Press the MANUAL Mode button. The
indicator light above Manual will blink.
Press RAISE or LOWER for each corner
to manually adjust. During the leveling
process a red light will blink on the
motorhome icon. Once that corner is level
the light will turn solid green. Proceed to the
next corner until the motorhome is level.
To control all four corners simultaneously,
use the ALL CORNERS RAISE and
ALL CORNERS LOWER buttons.
Turn ignition switch off when leveling is
achieved.
Travel Mode
Travel Mode exits Leveling Mode and
allows the height control valves to set proper
suspension height for travel. Initiate Travel
Mode prior to moving the motorhome. It may
take several seconds for the motorhome to
achieve full travel height once in Travel Mode.
WARNING:
The time required to achieve travel
height varies. Make sure that the
motorhome is at ride height before
driving. If the motorhome is too low,
severe damage can result.
To Use Travel Mode:
Enter Travel Mode before moving the
motorhome. Start the engine and press the
TRAVEL button. The system automatically
switches to Travel Mode when the parking brake
is released or if the Air Leveling System is turned
off or in any other mode other than Travel.
NOTE:
The tag axle will not raise until Travel
Mode is selected, initiating a two minute
time delay. This allows extra time for the
air system to pressurize before selecting
Tag Lift.
INFORMATION:
For detailed information and operating
instructions on the Air Leveling System,
refer to the OEM manual.
Service
The air leveling system includes a compressor
and air tank located curbside in the generator
compartment. Manually drain the air tank once
a month, or more, depending on operating
conditions and humidity levels.
The air tank drain is
located at the bottom
of the air tank. Open
the drain valve until
all air is released
from the tank. Wait
ve minutes before
closing the drain
valve to ensure that
all moisture has been
expelled.
CAUTION:
Always wear
safety glasses
when draining
the tank as
condensate will
be expelled under
pressure.
ENGINE - GENERAL INFORMATION
The diesel engine operates differently from
the conventional gasoline engine. Gasoline
engines control engine speed using a buttery
throttle plate to control air/fuel mixture inlet
ow. As the throttle plate opens, vacuum
created by the piston velocity draws the
metered fuel/air charge into the combustion
chamber, then ignites from a controlled electric
ignition source. Closing the throttle plate limits
the fuel/air supply, slows engine speed and
increases intake manifold vacuum.
