Lifting-platform mode
The system recognises lifting-platform mode
by evaluating the signals from the vehicle
level sender and by the length of time that
the stationary vehicle has been shutdown.
No fault is stored in the fault memory. This
mode is not displayed by the indicator lamp.

Any difference in height caused, for example,
by climbing out of or unloading the vehicle
after switching off the ignition, is corrected in
after-run mode.
Pre-travel and after-run mode
Any difference from the specified height
before driving commences or before ignition
on is corrected.
When the door, boot lid or terminal 15 is
actuated, the system is woken from sleep
mode and goes into pre-travel mode (see sec-
tion on Interfaces).
Any difference in height from the specified
value (e.g. due to the cooling of the air in the
pneumatic springs) is corrected by the accu-
mulator.
Sleep mode
After 60 seconds in after-run mode without
receiving an input signal, the system goes
into the energy-saving sleep mode. The sys-
tem leaves sleep mode briefly after 2, 5 and
10 hours to check the height level again.
