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 driving at speed, the vehicle is lowered automatically to improve driving safety and to reduce fuel consumption. You also have the option of manually adjusting the vehicle level.

AIRMATIC is comprised of the following functions and components:

All-round air suspension
Speed-dependent lowering
Manually selectable high level setting for greater ground clearance which can be adjusted using a level button
Vehicles with ADS PLUS: also Adaptive Damping System with constant adjustment of damping characteristics for improved driving comfort
