BAS PLUS (Brake Assist System
PLUS) with Cross-Traffic Assist

General information

i
Observe the "Important safety notes"
section ( page 70).
Y
BAS PLUS is only available on vehicles with
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational.
With the help of a sensor system and a
camera system, BAS PLUS can detect
obstacles:
that are in the path of your vehicle for an
R
extended period of time
that cross the path of your vehicle
R
In addition, pedestrians in the path of your
vehicle can be detected.
BAS PLUS detects pedestrians by using
typical characteristics such as the body
contours and posture of a person standing
upright.
If the radar sensor system or the camera
system is malfunctioning, BAS PLUS
functions are restricted or no longer
available. The brake system is still available
with complete brake boosting effect and BAS.
i
Observe the restrictions described in the
"Important safety notes"
section" ( page 72).
Y
BAS PLUS can help you to minimize the risk
of a collision with a vehicle or a pedestrian
and reduce the effects of such a collision. If
BAS PLUS detects a danger of collision, you
are assisted when braking.
