Level control system sensor in vehicles with
automatic headlight range control - general
information

Vehicles with gas discharge headlights come standard with
automatic headlight range control.

The automatic headlight range control requires information
about suspension compression and rebound at the front
and rear axles.

Electrical/electronic components and installation locations

For this, the position of the left lower control arm in relation
to the structure is transferred over a connecting link to the
left front level control system sensor G78 . The sensor
transmits electrical signals to the headlight range control
module.

On the rear axle, signals are transmitted to the control
module from the left rear level control system sensor G76 .

These signals are required for determining vehicle height.

The automatic headlight range control reacts automatically
to changes in vehicle inclination.

The vehicle height can change in the following situations:

n

Towing a trailer

n

Different load conditions; vehicle empty, vehicle
partially or fully loaded

n

Slow or fast driving habits

Caution!

Adjustment of headlights!

Note:

n

Checking the headlight basic setting is necessary
when:

n

The retaining clamp for the connecting link on the
lower control arm was loosened

n

The lower link/arm was removed and installed or
replaced

n

Work is performed on level control system sensor

n

The level control system sensor is replaced
