Driving and operating129
ActivationWhen reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic signal.
An obstacle is indicated by buzzers
and, depending on vehicle, is also
indicated in the Info-Display. The
interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the buzzer is continuous.
Notice
In versions with Info-Display
indication, the volume of the buzzer
can be adjusted via the Infotainment
system. Refer to Infotainment
system manual for further
information.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Deactivation
Deactivate the system by pressing
the r button on the instrument
panel with the ignition on. LED

fault, when selecting reverse gear a
continuous acoustic alarm will sound
for approx. 5 seconds, a
corresponding message appears in
the Driver Information Centre 3 88
and F illuminates in the instrument
cluster 3 84. Consult a workshop to
have the cause of the fault remedied.
