General information
Active Protection consists of various PreCrash
functions, which can vary depending on the
equipment.
The system is used to detect certain critical driv‐
ing situations that might lead to an accident. This
includes the following critical driving situations:
▷ Emergency stop.
▷ Severe understeering.
▷ Severe oversteering.
Certain functions of several systems can, within
the system limits, lead to Active Protection trig‐
gering:
▷ Front collision mitigation: automatic brake in‐
tervention.
▷ Front collision mitigation: Brake Assistant
▷ Rear collision preparation: detection of immi‐
nent rear collisions.
Safety information
Warning
The system cannot serve as a substitute for the
driver’s personal judgment. Due to the system
limits, critical situation could not be detected
reliably or in time. There is a risk of accident.
Adjust driving style to traffic conditions. Watch
traffic closely and actively intervene where ap‐
propriate.
Function
When the safety belt is fastened, the driver's and
passenger's belt straps are automatically tight‐
ened once after driving away.
In accident-critical situations, the following indi‐
vidual functions become active as needed:
▷ Automatic pretensioning of the front safety
belts.
▷ Automatic window closing up to a narrow
gap.
▷ Automatic closing of the panoramic glass
sunroof, including sun protection.
After a critical driving situation without an acci‐
dent, the front safety belts are loosened again.
If the belt tension does not loosen automatically,
stop the vehicle and unbuckle the safety belt us‐
ing the red button in the buckle. Fasten the
safety belt before continuing on your trip.
All other systems can be restored to the desired
setting.
PostCrash – iBrake
Concept
In the event of an accident, the system can bring
the vehicle to a halt automatically without inter‐
vention by the driver in certain situations. This
can reduce the risk of a further collision and the
consequences thereof.
At standstill
After coming to a halt, the brake is released auto‐
matically.
Harder vehicle braking
In certain situations, it can be necessary to bring
the vehicle to a halt more quickly than the Brake
Assistant allows.
To do this, quickly apply extra force to the brake.
For a brief period, the braking pressure will be
higher than the braking pressure that is achieved
by the automatic braking function. This interrupts
automatic braking.
Interrupting automatic braking
It can be necessary to interrupt automatic brak‐
ing in certain situations, for instance for an eva‐
sive maneuver.
Interrupt automatic braking:
▷ By pressing the brake pedal.
▷ By pressing the accelerator pedal.
