Rear leveling control keeps the rear section of the vehicle at the same height while driving regardless of load.
Shock absorbers (Four-C)*
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.
