Leveling control* and suspension

Rear leveling control keeps the rear section of the vehicle at the same height regardless of load. Leveling control may also remain active when the vehicle is parked.

Shock absorbers (Four-C)

On vehicles equipped with Four-C, the shock absorbers are adapted to the selected drive mode and the current vehicle speed. The shock absorbers are normally set to provide the best possible comfort and are adjusted continuously according to the road surface and the vehicle's acceleration, braking and cornering.

Transporting

When transporting the vehicle on a ferry, train or truck, only secure (lash) the vehicle around the tires, not using any other parts of the chassis. Changes in the pneumatic suspension may occur during transport, which could adversely affect the lashing and result in damage.
