faster than 18 km/h.

AIRMATIC
Function of AIRMATIC
AIRMATIC is an air suspension system with an all-
round level control system, which also ensures
the best possible suspension and constant
ground clearance, even with a laden vehicle.
When you drive at speed, the vehicle is lowered
automatically to improve driving safety and to
reduce fuel consumption. There is also the option
of raising the vehicle level while driving slowly,
e.g. for driving off public roads. The AIRMATIC
settings are dependent on the drive program
selection.
