The 4-level air suspension system is designed
as what is known as a pressure accumulator
system.
The pressure accumulator system increases
system availability, reduces noise
development and protects the power supply.
One of the special features of the system is
the ability to alter the ground clearance by 66
mm in 4 stages. The 4 stages can be
controlled manually or automatically (see
page 7 onwards).
The levels are designated as follows:
Level 1 = low level ( LL)
Level 2 = normal level ( NL )
Level 3 = high level 1 ( HL1)
Level 4 = high level 2 ( HL2)
Parking level PL = high level 1
