automatically, or via a remote control located at the driver’s seat�
The system will automatically adjust the ride height of the rear axle to
maintain a constant level position both laterally and longitudinally as
you are driving� The system monitors any changes in the chassis’
pitch and roll orientation to as you drive to aid in keeping the vehicle
level and at a consistent ride height at all times� It will make
necessary chassis ride height adjustments regardless of the load or
the vehicle’s center of gravity� It will not make the vehicle safer to
operate should the coach be overloaded, or if stowed luggage, cargo,
and equipment are improperly distributed and balanced within the
coach by the operator�
The VB Air Ride Suspension utilizes the following components,
which are installed on the rear axle:
1. A height sensor fitted between the body and the axle on both
sides of the vehicle� These sensors measure the ride height of
the vehicle;
2. The air compressor and Air Suspension Control Units (ASCU),
which takes the inputs from the height sensors and the remote
control to make adjust rear axle height on both sides; and,
3. Air springs which are inflated or deflated based on the ASCU’s
analysis of the pre-programmed baseline ride height of the
vehicle versus the current ride height, and the desired ride
height settings�
4. The remote control allows manual adjustments to the rear
chassis, and will only function while the vehicle is parked�
Refer to the image below and follow these steps to operate
the remote.
STEP 1
Start the coach and the “Check” light (1) on the remote
control will illuminate, indicating the system is active� If
there is an error or problem with the system, the “Check”
light will flash and generate a beeping tone. If this
occurs, please contact your authorized American Coach
dealership for assistance�
STEP 2
With the engine running, and the vehicle in park with the
safety brake on, you may use the “Up / Down” buttons
(2 and 3) on the remote to raise or lower the rear of the
vehicle� This is useful when attempting to make minor ride
height adjustments to level the coach at a campsite�
STEP 3
Establish the desired ride height per Step 2 above� Then
save desired manual ride setting to either of the two
memory buttons by pressing and holding the desired
memory button (6 or 7) on the remote control.
STEP 4
To temporarily deactivate the system, press the “Service”
button (8), which will illuminate. Once illuminated the
system is off, which is necessary when having service
work performed on the chassis� Touching the button again
will turn the system back on�
STEP 5
To return the vehicle to ride height while it is stationary and
parked, press and hold the “Front / Rear” button (5) until
you hear a beep� The system will then attempt to adjust
the air suspension to achieve the desired ride height�
When activating the system or increasing the ride height, the electric
air compressor may start� Decreasing the ride height may cause a
hissing sound, which is air being released from the system� These are
normal sounds�
