Notes
The visibility of the displays in the Head-Up Dis-
play is influenced by:
> Sunglasses with certain polarization filters
> Certain seating positions
> Objects on the cover of the Head-Up Dis-
play
> Wet road surface and unfavorable lighting
conditions
If the image is distorted, please have the basic
setting checked at a BMW center.
Special windshield
The windshield is part of the system. The shape
of the windshield complies with the require-
ments of the Head-Up Display to enable a pre-
cise display. A film in the windshield prevents
the double images from being displayed.
Windshield replacement should be carried out
by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.
