Level control* and shock absorption

Level control regulates the car's suspension and shock absorption characteristics automatically to ensure optimum comfort and functionality while driving. It is also possible to adjust the level manually to facilitate loading.

Shock absorption (Four-C)*

On a car equipped with Four-C, the shock absorption is adapted according to the suspension setting selected and the speed of the car. Shock absorption is normally set for optimum comfort and is regulated continuously depending on road surface, car acceleration, braking and cornering. If a firmer chassis is required, the suspension setting should be set to Suspension feel firm.

Level control and shock absorption

Using level control, the car's ground clearance is adjusted to a lower level at higher speeds, which reduces wind resistance and increases stability. Shock absorption is set for optimum comfort and is regulated continuously depending on the road surface, the car's acceleration, braking and cornering.

The driver display indicates when level control is in progress.

When a side door or the tailgate is open, the following applies:
  • If a side door is open, the level can only be regulated upwards.
  • If the tailgate is open, the level can only be regulated downwards.

During parking1

During parking, make sure you allow adequate space above and below the car since the car's ground clearance may vary e.g. depending on the outside temperature, how the car is loaded or the use of loading mode.

The level may also be adjusted some time after the car has been parked. This is to compensate for any changes in height that may occur due to temperature changes in the air springs when the car cools down.

During transport

During transport of the car on a ferry, train or truck, the car must be lashed around the tyres and not around other parts of the chassis. Changes in the level control may occur during transport, which could have a negative effect on the lashing.

Symbols and messages

If a fault arises with the level control, a message is shown in the driver display.
