Automatic Headlight Beam
Adjustment Vehicles with Bi-Xenon headlights feature
dynamic headlight beam adjustment.
When the ignition is switched on, the level of the

dance with the vehicle load.
The level of the headlight beam is automatically
kept constant during acceleration and braking. Checking operation 1. Switch the low beam on.
2. Insert ignition key and switch ignition on.
The light beam first dips all the way down and
is then adapted to the vehicle load.

adjustment system must be checked by an autho-
rized Porsche dealer.
