For models: E39, E46, and E53
Note:
After finished basic adjustment, the light will automatically turn on/off at ignition on/off and the light switch in pos. 2.
If the vehicle is equipped with RLS (rain/light sensor) there is a light sensor that automatically controls the low beams depending on the light intensity of the surroundings, e.g., low beams are activated automatically at dusk or when entering a tunnel. Cars featuring RLS are identified easiest by the position to the left of the 0-position marked with a light symbol and an A. For the light sensor to be active, the light switch must be in position A. It is also possible to do this adjustment on cars featuring RLS (rain/light sensor) since this adjustment does not affect the light sensor's function with the light switch in position A.
Test conditions:
Ignition on.
Procedure:
Select the function: "Automatic low beam" and press "OK".
A dialogue box shows current status if automatic low beam is active or inactive.
Select "OK" to activate/deactivate automatic low beam.
Turn the ignition off and on, and press "OK".
New status is shown if automatic low beam is active or inactive.
Turn the ignition off and on, and then turn off the ignition and wait for 15 seconds.
