Notes
The visibility of the displays in the Head-Up Dis-
play is influenced by:
> Sunglasses with certain polarization filters
> Certain sitting 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 base
setting checked at a BMW center.
Specialized windshield
The windshield is a part of the system. The
shape of the windshield complies with the
requirements of the Head-Up Display to enable
a precise display. A film in the windshield pre-
vents 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.
Care instructions
You can find everything you need to know on
this topic by consulting the Caring for your vehi-
cle brochure.
Only clean the cover of the Head-Up Dis-
play with a soft, nonabrasive cloth or with
a display cleaning cloth; otherwise, you may
damage it.

BMW Night Vision*
The concept
BMW Night Vision is a driver assistance system
that is designed to provide enhanced vision for
certain objects at night. This can be especially
helpful for detecting people and larger animals.
When objects are detected, the driver may be
able to take appropriate action sooner. For
example, the driver may identify and detect the
presence of persons or animals in the road
ahead or off to the sides and can be more alert,
slow down or stop, blow the horn etc. The driver
can decide which actions are appropriate and
then react accordingly.
A certain area in front of the vehicle is viewed by
an infrared camera and a generated image is
shown on the Control Display. The resulting
thermal image shows the relative heat radiation
of the objects present in the camera's field of
view. Warmer objects appear brighter and
cooler objects appear darker. Contrast is
dependent on the temperature difference
between the objects and the background and
on the amount of heat radiation of the object
itself. As a result, it is quite possible that a per-
son is not continually recognizable as a person
in shape, since the thermal radiation can be
affected by different clothing which blocks heat
loss. Objects with little temperature difference
to the surrounding area, or little heat radiation
are less noticeable, for example in cold weather.
