Air suspension
12.1 GENERAL
Vehicles with air suspension are equipped with an Electronically Controlled Air
Suspension (ECAS).
On vehicles equipped with air suspension, a remote control unit is used to operate the
vehicle height.
The remote control unit is located against the console of the driver seat or the door
pillar. This control unit can only be operated when the ignition is switched on and the
vehicle speed is lower than 25 km/h.
The chassis height parameters are stored in the electronics of the air suspension. If the
chassis height is not equal to the stored desired height, the chassis adjust itself.
NOTE: The memory keys can also be used at speeds over 25 km/h.
The remote control can be used to set the chassis to the most suitable height for:
– driving height
– coupling or uncoupling a trailer
– loading or unloading the vehicle
WARNING!
– Driving a vehicle that is not at normal driving height, other than for
example coupling and uncoupling a semi-trailer, is not permitted.
Driving a vehicle that is not at normal driving height, other than for
coupling or uncoupling and/or loading or unloading, can result in
unstable vehicle behaviour. This can lead to dangerous situations,
serious injury and damage to the vehicle. Also the legally permitted
driving height can be exceeded.
WARNING!
– Always set the chassis in the lowest position during tipping and
unloading heavy loads like containers.
Unloading heavy loads from a vehicle with the air suspension not in
the lowest position can result in an unstable vehicle during unloading.
This can lead to dangerous situations and serious injury and damage
to the vehicle.
12.2 REMOTE CONTROL
The basic remote control has four buttons and is used for vehicles without ALM and
or front air suspension.
The extended remote control has a 14 button design and is used for vehicles with ALM
and or front air suspension.
It is possible to exchange between a basic and extended remote control unit. This does
not mean ALM is functioning if the vehicle is not equipped with it.
