Task

The raise/lower electronic level control switch (with model 639 raise or lower level control switch) enables the level of the vehicle's rear axle to be increased or reduced in each case by approx. 60 mm. The lock electronic level control switch can be used to deactivate the automatic level adaptation, this is, e.g. necessary when changing a wheel or performing repair work on the vehicle lift. Finally, the lock electronic level control switch can be used to activate the electronic level control (ELC [ENR]) system and therefore the automatic level adaptation again.
