System limits
In the event of serious accidents, it may not
be possible to store recordings if the damage
to the vehicle is too great or the power supply
was interrupted.
Active Protection
Principle
Active Protection prepares occupants and the
vehicle for a possible accident in critical driving
or collision situations.
General information
Depending on vehicle equipment and national-
market version, Active Protection consists of
various PreCrash functions.
The system is used to detect certain critical
driving situations that might lead to an acci-
dent. This includes the following critical driving
situations:
▷ Emergency braking.
▷ Severe understeering.
▷ Severe oversteering.
Certain functions of several systems can,
within the system limits, lead to Active Protec-
tion triggering:
▷
Forward Collision Warning with light brak-
ing function: automatic brake intervention.
▷ Front collision mitigation: Brake Assistant
▷ Rear-end collision preparation: detection of
impending rear-end collisions.
Safety information
Warning
The system cannot serve as a substitute for
the driver’s personal judgment. Due to the
system limits, critical situations might not be
detected reliably or in time. There is a risk
of accident. Adjust driving style to traffic con-
ditions. Watch surrounding traffic closely and
actively intervene where appropriate.
Function
Depending on vehicle equipment: In critical ac-
cident situations, the following individual func-
tions become active as needed:
▷ Automatic closing of the windows. The win-
dows remain open with a small gap.
▷ The glass sunroof/panoramic glass sunroof
closes automatically. The sun protection is
also closed.
▷ Automatic Positioning of the backrest for
the front passenger seat.
Systems can be returned to the desired set-
tings following a critical driving situation with-
out accident.
PostCrash – iBrake
Principle
In certain accident situations, the PostCrash
iBrake can automatically bring the vehicle to a
standstill without intervention by the driver.
General information
The PostCrash iBrake can reduce the risk of a
further collision and its consequences.
At standstill
After coming to a halt, the brake is released
automatically.
Harder vehicle deceleration
In certain situations, it may be necessary to
bring the vehicle to a halt more quickly than
automatic braking allows.
To do this, quickly apply extra force to the
brake. For a brief period, the brake pressure
will be higher than the brake pressure that is
