down out of use or has been activated, have it
checked, repaired or dismantled and the airbag
generators scrapped only by BMW Service or
by a workshop that operates to BMW specifica-
tions and has suitably trained personnel and the
necessary permits for handling explosive
devices. Unskilled interference with the system
could lead to its failure or to accidental trigger-
ing with the risk of injury.
Operational status of airbag system
From radio readiness onwards, the warning
light comes on for a short time to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system faulty
>
The warning light does not come on follow-
ing radio readiness.
>
The warning light is on permanently.
In the event of a fault in the airbag system,
have it checked without delay, as there is
otherwise the risk that the system will not func-
tion as intended even if a sufficiently severe
accident occurs.<

BMW Night Vision*

The principle
BMW Night Vision is a night vision system that
can assist you when driving in the dark.
An infrared camera scans the area in front of the
vehicle and displays the image on the control
display.
This image is a thermal image, i.e. it shows the
heat radiated by objects within the camera's
90

range. Warm objects appear light, and cold
objects dark. The camera detects objects by
the temperature difference between objects
and their background, as well as by the heat
radiated by the object itself. It is therefore
entirely possible that persons will not be fully
identifiable as persons because the radiation of
heat by their body is influenced by different
clothes on different parts of their body.
Objects with a lower temperature difference
compared with their surroundings or radiating
less heat are fundamentally more difficult to
identify.
System limits
The system operates less effectively in situa-
tions such as the following:
>
On steep crests or dips and on tight bends
> In tunnels, as the system is able to detect
less contrast there
> If the camera is contaminated
> In thick fog and heavy rain or snow. These
may reduce the contrast and cause the
brightness of the image to fluctuate.
BMW Night Vision is no substitute for
your personal assessment of the visibility
conditions and traffic situation. Always base
your responses on what you can actually see in
front of you and adjust your speed in line with
the actual visibility conditions, to avoid safety
risks.<
