Acoustical signals

The distance to an obstruction in the
front is indicated by a higher interval
tone, while the distance to an obstruc-
tion in the rear is indicated by a deeper
tone. As the distance between vehicle
and object decreases, the intervals be-
tween the tones become shorter. A
continuous tone indicates the presence
of an object less than 1 ft. (30 cm)
away.
The warning signal is canceled after ap-
prox. three seconds if the distance to
the obstruction remains constant during
this time (if you are moving parallel to a
wall, for instance).
System malfunctions are indicated by a
short, continuous tone and a flashing
indicator lamp (indicator lamp only
when the system is activated by shifting
the transmission into "R").
Switch the system off and consult an
authorized BMW center to have the
problem corrected.
