With rear level control, the car maintains the same height at the rear while driving, regardless of load.
Shock absorption(Four-C)
(Option/accessory)
On a car equipped with Four-C the shock absorption is adapted according to the drive mode selected and the speed of the car. Shock absorption is normally set for optimum comfort and is regulated continuously depending on the road surface, the car’s acceleration, braking and cornering.
During parking
(Option/accessory)
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 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 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.
| 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 of the car’s rear axle to target height in progress. |
