Air suspension
GENERAL
The remote control unit is used to operate the vehicle height on vehicles equipped
with electronically controlled air suspension (ECAS).
The remote control unit is located against the console of the driver's seat and can
only be operated with the ignition switched on and when the vehicle speed is lower
than 9 km/h (5 mph).
The electronically controlled air suspension system (ECAS) is controlled by a
microprocessor. Chassis height parameters are stored in the memory. If the actual
chassis height is not in conformity with the set parameters, it will automatically be
adjusted. The remote control unit can be used to set the chassis to the most suitable
height for coupling/uncoupling a trailer or for loading/unloading the vehicle.
Driving a vehicle that is not at normal driving height, other than for
coupling and uncoupling a semi-trailer is not permitted. The driving
properties of the vehicle will be adversely affected and the legally
{permitted driving height could be exceeded.
