General Information 

Vehicles with level control system and/or with gas-discharge headlights have an automatic vertical aim control 
system as standard equipment --> 94 - LIGHTS, SWITCHES - EXTERIOR . 

To function properly, the vehicle level control system and automatic vertical aim control system require 
information about compression travel or rebound travel at front and rear axles. 

For this, position of left/right control arm in relation to body is transferred via a coupling rod to Left Front
