Function
The electrical headlamp range adjustment operates dynamically. Every change in the vehicle level is determined
and signaled to the headlamp range adjustment control module (N71) by the rear axle sensor and the front axle
sensor (A51, A52). The control module (N71) compares the vehicle level and the headlamp position. If
necessary, the headlamp setting is corrected by the control module (N71) via the headlamp range adjustment
motors (E1m1, E2m2). The headlamp position is only corrected if a modified vehicle level is signaled to the
control module (N71) by the front and rear axle sensors (A51, A52) for a specific time span.
Headlamp range adjustment control module (N71)
The headlamp range adjustment control module (N71) processes the signals from the front and rear axle sensors
(A51, A52) as well as the position of the headlamp range adjustment motors (E1m1, E2m1). After evaluating
these signals, commands are sent to the headlamp range adjustment motors (E1m1, E2m1).

A sensor is fitted to the front axle and to the rear axle and the sensors pick up the instantaneous vehicle level at
the control arm. These sensors (A51, A52) transmit the determined vehicle level to the control module (N71).
Headlamp range adjustment motor (E1m1, E2m1)
The position of the reflectors is signaled to the headlamp range adjustment control module (N71) by a
potentiometer in the headlamp range adjustment motor. The motors (E1 m1, E2m1) receive a command from
the control module (N71) for correcting the headlamp position. If the low beam is switched on and the key is in
position 2, the motors are referenced. The reflectors are moved to the lowest position and then, depending on
the vehicle level, moved to the correct position.

XENON HEADLAMPS, FUNCTION - GF82.10-P-2007-01GH
Function
The combustion chamber of the xenon lamp is filled with xenon and a mixture of metal halide salts. This
mixture is ignited by high voltage. The color of the light has a characteristic similar to daylight.
When the low beam lamps are switched on the xenon headlamp control module (E1 n1, E2n1) activates the
xenon headlamp control module and ignition module (E1n2, E2n2) via the control voltage within a few
milliseconds.
As a result of a high voltage surge (approx. 20 kV) of the ignition device, an arc forms between the electrodes,
and the xenon lamp is ignited.
When an arc of sufficient stability is detected, the control electronics of the xenon lamp control module (E1n1,
E2n1) switches over to power-limiting mode. The electric power is regulated to 35 W. A voltage converter
generates the voltage of approx. 85 V (~) necessary for the reliable function of the xenon lamp. For technical
reasons the xenon lamp has a timed startup characteristic. After switching on, 50 % of the luminosity is reached
within 1 to 2 seconds and full luminosity is reached after approx. 30 seconds.
