Multi-collision Brake
The multi-collision brake has been designed to provide effective assistance for the driver in
the moments after an accident. Multi-collision brake triggers automatic controlled braking
once an initial collision has been detected so as to reduce the intensity of further accidents
after a collision and can help prevent follow-on collisions with oncoming traffic.
The triggering of the multi-collision brake is based on a collision being detected by the
airbag sensors. The ESP control unit limits the deceleration of the vehicle by the multi-
collision brake to a defined value and vehicle speed. The vehicle can still be controlled by
the driver, even when automatic braking is taking place. The driver can interrupt the multi-
collision braking at any time by accelerating or braking even more strongly.
Park Assist 2
O
The second generation Park Assist system actively helps the driver when reversing into 90º
parking bays, as well as reversing into and driving out of parallel parking spaces. The system
works by using sensors mounted either side of the front and rear bumpers together with
parking distance sensors front and rear. To park, the driver simply presses the Park Assist
button to select the type of parking manoeuvre and uses the appropriate indicator as the car
slowly passes the potential parking space. Sensors scan the size of the parking space as the
car is driven past and the driver is alerted if the parking space is big enough. If there is
sufficient space, the driver stops the car, selects reverse and lets go of the steering wheel.
Park Assist will alert the driver of the intended path and subsequently the appearance of
obstacles in the Multi-Function Display, within the driver’s field of vision. Park Assist
then actively supports the driver by taking over the steering control and parks the vehicle
in the available space using the ideal course, if necessary with several moves. The driver
can however take over the control of the steering at any time and end the automatic
parking procedure.
Park Assist cannot replace the driver’s attentiveness. The driver is still legally responsible for the vehicle. If the
driver notices a risk that pedestrians, other vehicles or objects could be damaged or if they are uncertain of the
risk, they will need to react accordingly and stop the vehicle, ending the function.
Proactive occupant protection system
O
The proactive occupant protection system incorporates active and passive safety elements.
When the system detects a potential accident situation, the occupants and the vehicle are
prepared for a possible accident. Automatic tensioning of the seat belts secures the driver
and front passenger in their seats to attain the best possible protective potential of the
airbag and belt system. In case of high transverse dynamics the side windows (and optional
panoramic sunroof) are also closed, leaving just a small air gap. Closing of the windows
offers optimal support to the head and side airbags which results in the best possible
protection.
