Leveling control* and suspension
Self-leveling and suspension functions are controlled automatically.
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.

If a problem occurs with the leveling control, a message will be displayed in the instrument panel.
