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.

Automatic braking to reduce damages
If the rear cross traffic alert detects that
someone else on the road is approaching the
rear of the vehicle and the driver does not
step on the brake, the system will engage the
brakes automatically.
The parking system helps the driver by auto-
matically engaging the brakes to reduce any
damage. The automatic intervention on the
brakes takes place when driving in reverse at
approx. 1-12 km/h (1-7 mph. After detecting
that the vehicle is stationary, the system
keeps it that way for around 2 seconds.
After automatically braking to reduce dam-
age, the system will not be able to automati-
cally brake again for approximately 10 sec-
onds.
You can interrupt the automatic braking by
stepping hard on the accelerator pedal or
the brake pedal in order to regain control of
the vehicle.
WARNING
The smart technology incorporated into
the rear cr
oss traffic alert cannot over-
come 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
traffic, e.g., in high-traffic areas or when
crossing multiple lanes.
●
Be sure to always be aware of the vehi-
cle's surroundings, since the system often
fails to detect things such as bicycles or
pedestrians.
●
The rear cross traffic alert itself will not
brake the vehicle to a complete stop.
●
When the ESC is in Sport* mode or if the
ESC or ASR are disconnected, there will be
no automatic braking.

It is only displayed if the vehicle is equipped
with a parking system.
