Assistant systems
Lane departure warning (Side Assist) with rear cross traffic alert (RCTA) and door opening warning (Exit Assist)
185
1)
It is only displayed if the vehicle is equipped with a parking system.
The faster the vehicle approaches, the sooner
an indication will be displayed in the control
lamp, because the lane departure warning
takes into account the speed differential with
other vehicles. Thus even though the distance
from the other vehicle is identical, the indica-
tion will appear sooner in some cases and later
in others.
Physical limitations inherent to the system
In some situations the lane departure warning
may not interpret the traffic situation correctly.
I.e. in the following situations:
•
on tight bends;
•
in the case of lanes with different widths;
•
in areas with significant gradient changes;
•
in adverse weather conditions;
•
in the case of special constructions to the
side of the vehicle, e.g., high or irregular divid-
ers.
Rear cross traffic alert (RCTA)

detected area around the vehicle that is
driving off.
Park Assist uses the radar sensors on the rear
bumper
to monitor traffic cross-
ing behind the vehicle as it reverses out of a
parking bay, or as it is being manoeuvred, for
example in very low visibility conditions.
When the system detects a relevant vehicle on
the road that is approaching the rear of the
vehicle
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 or yellow 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
approaching in transverse direction

Automatic braking to reduce damages
If the rear cross traffic alert detects that some-
one 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 damage,
the system will not be able to automatically
brake again for approximately 10 seconds.
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.
