used as a continuous viewing window for driv-

No system, no matter how sophisticated, can
operate without limitations. BMW Night Vision
operation is subject to physical and environ-
mental limitations that will reduce the ability of
the system to detect and display a clear thermal
image. Some of the situations in which these
limitations can occur are:
> on steep hilltops or depressions and in tight
curves
> in tunnels, as the contrast is inherently low
> when the camera lens is dirty
> in dense fog, heavy rain or snowfall
> when displaying very hot objects such as
transformers, car exhausts etc.
> when the image briefly freezes during nor-
mal system adjustment.
BMW Night Vision's potential benefits
can be limited by the driving style of the
driver, the size and relative temperature of the
detected objects, dirt or contamination on the
camera lens, adverse weather like snow, rain or
fog, and other factors not mentioned here. It will
always be the driver's responsibility to drive at a
speed and in a manner that recognizes potential
hazards and adjust accordingly.
BMW Night Vision is not a substitute or replace-
ment for the driver's responsibility to adapt to
visibility and traffic conditions. The forward view
illuminated by the headlamps must always be
the basis for making safe driving decisions, oth-
erwise a safety risk will result.

Activating BMW Night Vision
1. Turn the light switch to position 2 or 3, refer
to page 104 .
2. With low beams switched on:
> Press the button. Depending on the
vehicle's equipment, the location of the
button may differ somewhat.
> Press one of the programmable buttons
on the steering wheel, refer to page
57 .
The image will be displayed on the Control Dis-
play after a few seconds. Depending on the last
mode selected, either the normal or full screen
image will be displayed.
Due to the system's need to adjust periodically,
a still image is displayed at certain intervals for
fractions of a second. This is normal and not an
indication of a problem.
To prevent driving without headlamps, at a
speed of more than approx. 3 mph/5 km/h and
when dark, the thermal image on the Control
Display is only shown when the low beams are
on.
Deactivating BMW Night Vision
> Press the button.
