Once the source of the problem has been
eliminated, the system may be reconnected.

If the system still behaves unpredictably,
have it checked by a specialised workshop.

to monitor traffic cross-

parking bay, or as it is being manoeuvred, for
example in very low visibility conditions.

Rear cross traffic alert (RCTA)
Parking and manoeuvring
When the system detects a relevant vehicle on
the road that is approaching the rear of the
›››
vehicle
Fig. 155, an acoustic alarm may
sound if the relevance so requires it.
In addition to the acoustic alarm, the driver is
also informed by means of a visual signal on
infotainment system display. This signal is dis-
played in the form of a red strip at the back of
the image of the vehicle on the infotainment
system screen. This strip displays the side of
the vehicle towards which traffic is approach-
ing in transverse direction
.

Connecting and disconnecting
The rear cross traffic alert can be activated
and deactivated by accessing the Assistants
menu of the infotainment system. It can also
be found in the Park Assist Settings menu.
Additionally it can be switched on and off by
accessing the Assistants menu on the instru-
ment cluster.
When the vehicle is restarted, the last adjust-
ment in the system will remain active.
Trailer mode
The rear cross traffic alert will be automatically
deactivated and it will be impossible to activate
them if the tow hitch is electrically connected
to a trailer or other similar object. As soon as
the driver starts driving, a message appears on
the instrument cluster screen indicating that
the assistant is deactivated.
Once the trailer is uncoupled from the vehicle,
the assistant will return to its initial state prior
to the moment when the trailer was electrically
connected.
If the tow hitch is not factory fitted, then the
rear cross traffic alert will have to be deactiva-
ted manually when driving with a trailer.
WARNING
The smart technology incorporated into the
rear cross traffic alert cannot overcome the
limits imposed by the laws of physics; it only
works within the limits of the system. The
parking assistant function should not tempt
you into taking any risks. The system is not a
replacement for driver awareness.
●
The system should never be used in limi-
ted visibility conditions or complicated traf-
fic, e.g., in high-traffic areas or when crossing
multiple lanes.
