Shock absorption(Four-C)
(Option/accessory)
Level control and shock absorption
The system is adapted according to the selected drive mode and according to the speed of the car. 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 normally 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 parking
- 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, the use of loading mode or the drive mode that is selected after starting.
- The level may also be adjusted sometime 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 the transport of the car on a ferry, train or truck, the car must be lashed around the tires 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.
| Symbol | Message | Specification |
|---|---|---|
| | Suspension Deactivated by user | The active self-levelling has been switched off manually by the user. |
| | Suspension Temporarily reduced performance | The performance of the active self-levelling has been temporarily reduced due to extensive system use. |
| | Suspension Service required | A fault has occurred. Visit a workshop as soon as possible. |
| | Stop safely Suspension failure | A critical fault has occurred. The car’s driving performance is significantly reduced, stop safely. Have the car transported (raised with all wheels on the flat-bed) to a workshop if the message is shown when the car is stationary. |
| | Slow down Suspension Car too high | A fault has occurred. The car’s driving performance is reduced, slow down until the symbol disappears. Contact a workshop if the message is shown when the car is stationary. |
| | Suspension Auto-adjusting car level | Level control to target height in progress.

Settings for level control
(Option/accessory)
- Switch off the air suspension when the car is to be jacked up in order to prevent problems with automatic level control.
- Regulate the height of the car to facilitate loading, or on entry and exit.
Adjusting loading mode
Use the buttons in the cargo area to regulate the height of the car’s rear section and facilitate loading and unloading or when connecting or disconnecting a trailer.
Activating or deactivating air suspension
In certain cases, the function must be deactivated e.g. before the car is raised with a jack. The difference in level created when lifting with a jack would otherwise mean the automatic control starting to adjust the height, creating an undesired effect.
The setting is made in the centre display:
- Press
- Select Driving.
- Select to activate or deactivate air suspension.
