Abstract
A level control system for a motor vehicle having a vehicle body includes a plurality of air springs which can be filled or discharged with pressurized air to control the level of the vehicle body. A first control apparatus controls the functions of filling and discharging the air springs in dependence upon the level of the vehicle body. A communications channel interconnects the first control apparatus to a second control apparatus. A switch triggers an additional function in the level control system and this switch is movable between a first switching state and a second switching state. The switch is connected to the second control apparatus and the second control apparatus functions to transmit a signal sequence via the communications channel to the first control apparatus when the switch is transferred from the first switching state into the second switching state. The first control apparatus operates to carry out the additional function when the first control apparatus receives the signal sequence.
