Section 01 TECHNICAL MANUAL
Subsection 02 (AIR CONTROLLED SUSPENSION (ACS))
The requested setting is controlled by the ACS
electronic module. The module is equipped with
a pressure transducer to keep air pressure con-
stant in the system. Depending on the rider ad-
justment, the module will increase pressure using
the compressor or release pressure using the so-
lenoid release valve.
ACS Setting Acknowledgement
If ACS suspension was set to
ACS 5
or
ACS 6
be-
fore shutting down the vehicle, the multifunction
gauge will scroll an acknowledgement message
at startup.
To acknowledge the ACS suspension setting,
press and release ACS button while message
appears.

TYPICAL
1. ACS button
NOTE: If the message is not acknowledged, the
suspension will automatically return to setting
ACS 3
.
NOTE: If the selector button in the multifunction
gauge is pressed while the acknowledgement
message appears, the suspension will directly
return to setting
ACS 3
.
NOTE: If the vehicle transmission is set to RE-
VERSE position at startup, the override message
will be displayed instead of acknowledgement
message.
Using the Auxiliary Line to Inflate Tires
The ACS system is equipped with an auxiliary line
specially designed to inflate tires. The air pressure
in this auxiliary line is controlled by a second pres-
sure transducer connected to the ACS module.

1. Auxiliary line adaptor to inflate tire
To ensure that the use of the auxiliary line will
not change the pressure setting inside shock
absorber, the system has been divided in two
zones using check valves. With this layout, both
pressure zones are independent to eliminate any
air pressure variation.
NOTE: The auxiliary line output pressure will vary
according to the ACS suspension setting. The
ACS 1
adjustment will provide less pressure than
the
ACS 6
adjustment.
NOTICE
Never inflate tires above the recom-
mended pressure.

Releasing Air Pressure in System for
Servicing
It is recommended to release air pressure in the
system before servicing any components.
1. Remove seats.
2. Remove RH side panel.
3. Unscrew pneumatic valve cap.
