Bi-Xenon lights with automatic headlight
levelling system must first do a refer-
ence run before aiming: Start the engine
and let the headlights do a reference
run. Turn off the engine but leave the low
beam on.
Cars with halogen lights:
Turn on the low beam headlights.
Both variants:
Place a piece of cardboard or equivalent
(although not directly on the lens) in front
of the headlight not being aimed. This
should allow the beam cut-off of the
headlight being aimed to be seen on the
flat surface.6 Turn the two vertical aiming screws
simultaneously in the same direction
indicated on the headllight until the hori-
zontal cut-off of the headlight is aligned
with the horizontal line on the wall.
7 If an optical headlight aimer device is
used follow point 1 and 2 and center the
lens of the optical headlight aimer
device at the intersection of the two markers on the headlight lens.
Then follow the instructions in the optical
headlight aimer instruction manual and
point 1, 2, 5, and 6 in this instruction.
NOTICEDo not cover a headlight directly on the
lens to improve beam cut-off when aim-
ing. Covering a headlight may cause
excessive heat build-up that may cause
damage to the headlight.Correctly adjusted low beam Horizontal line on wall or other flat surface
