Driving and operating
Two different length settings can be
set in the vehicle personalisation
● Maximum length: for trailers with
a length of more than 9 metres.
● Automatic length detection: the
system detects the trailer length
automatically (3 metres, 6 metres
and 9 metres).
When automatic detection has been
set, the respective length icon is
displayed in the Driver Information
Centre.
In order to enable the automatic
length detection, it may be necessary
to make a 90° turn.
The rear cross traffic alert is
deactivated, as soon as the trailer
detection has been activated.
