When the light is switched on, the brightness of
the instrument illumination can be adjusted by
turning thumb wheel A.
The headlights can be steplessly adjusted to the
vehicle loading condition using the manual
headlight beam adjustment control B. Adjusting
the headlights ensures that on-coming traffic is
not dazzled.
The headlights can only be adjusted when the
dipped beam is switched on.
f Rotate thumb wheel downwards to lower the
light beam.

The positions correspond to the following vehicle
loading conditions:
Automatic headlight beam
adjustment
Vehicles with Bi-Xenon headlights feature
automatic headlight beam adjustment.
When the ignition and dipped beam are switched
on, the level of the headlight beam automatically
changes in accordance with the vehicle load. The
level of the headlight beam is automatically kept
constant during acceleration and braking.
Checking operation
1. Switch the dipped beam on.
2. Switch ignition on.
The light beam first dips all the way down and
is then adapted to the vehicle load.
If this test point not satisfied, the headlight beam
adjustment system must be checked.
f Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
