Rear leveling control keeps the rear section of the vehicle at the same height while driving regardless of load.
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 help optimize comfort and are adjusted continuously according to the road surface and the vehicle's acceleration, braking and cornering.
Parking1
When parking, make sure that there is adequate space above and below the vehicle since ground clearance may vary depending on e.g. ambient temperature, how the vehicle is loaded, if loading mode is used, etc.
The level may also be adjusted a period after the vehicle is parked. This is to compensate for any height changes that may occur due to temperature changes in the air springs when the vehicle cools.
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 leveling control may occur during transport, which could adversely affect the lashing and result in damage.
Symbols and messages
If a problem occurs with the leveling control, a message will be displayed in the instrument panel.
| Symbol | Message | Meaning |
|---|---|---|
 | Suspension Deactivated by user | Active leveling control has been switched off manually by the user. |
| Suspension Temporarily reduced performance | Active leveling control performance has been temporarily reduced due to extensive system use. |
 | Suspension Service required | A fault has occurred. Visit a workshop2 as soon as possible. |
 | Stop safely Suspension failure | A critical fault has occurred. The vehicle's driving performance is significantly reduced. Stop safely. Have the vehicle towed (raised with all four wheels on the bed of a tow truck) to a workshop2 if the message is displayed while the vehicle is stationary. |
| Slow down Suspension Vehicle too high | A fault has occurred. The vehicle's driving performance is reduced. Slow down until the symbol disappears. Contact a workshop2 if the message is displayed while the vehicle is stationary. |
 | Suspension Auto adjusting vehicle level | Level control of the car's rear axle to target height is in progress. |
