Automatic Headlight Beam Adjustment Vehicles with Bi-Xenon headlights feature
dynamic headlight beam adjustment.
When the ignition is switched on, the level of the
headlight beam automatica lly changes in accord-
ance 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.
If this test item is not met, the headlight beam
adjustment system must be checked by an author-
ized Porsche dealer.
Welcome Home LightingSwitching on

Maintenance note
f Periodically clean the wiper blades with a win-
dow cleaner, especially after the vehicle has
been washed in a car wash. We recommend
Porsche window cleaner. If they are very dirty
(e.g. with insect remains), they can be cleaned
with a sponge or cloth.
If the wiper blades rub or squeak, this may be as
a result of the following:
If the vehicle is washed in an automatic car wash,
wax residues may be adhering to the windshield.
These wax residues can only be removed by using
a window cleaner concentrate.
f Please see the chapter “WASHER FLUID” on
Page 200.
