dent. This includes the following critical driving
situations:
▷ Emergency braking.
▷ Severe understeering.
▷ Severe oversteering.
General information
Certain functions of some vehicle systems can
lead to Active Protection being triggered within
their system limits:
▷ Automatic brake intervention by Forward
Collision Mitigation.
▷ Brake power assistance provided by For-
ward Collision Mitigation.
▷ Detection of an impending rear collision by
the Rear-collision warning.
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.
PreCrash functions
Depending on vehicle equipment and require-
ments, Active Protection activates the follow-
ing individual functions in critical driving situa-
tions:
▷
Automatic closing of the windows.
The windows remain open with a small
gap.
▷ The glass sunroof/panoramic glass sunroof
closes automatically.
The sun protection is also closed.
Systems can be returned to the desired set-
tings following a critical driving situation with-
out accident.
PostCrash – iBrake
Principle
In certain accident situations, PostCrash iBrake
can automatically bring the vehicle to a stand-
still without intervention by the driver. This can
reduce the risk of a further collision.
After coming to a halt, the brake is released
automatically.
The driver can intervene manually to brake the
vehicle more sharply or cancel automatic brak-
ing.
Harder vehicle deceleration
In certain situations, it may be necessary to
bring the vehicle to a halt more quickly than
automatic braking with PostCrash iBrake al-
lows.
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
achieved by the automatic brake function. Au-
tomatic braking is interrupted.
Abort automatic braking
It may be necessary to cancel automatic brak-
ing with PostCrash iBrake in certain situations,
e.g., when making an evasive maneuver.
Automatic braking can be canceled by doing
as follows:
▷
Depressing the brake pedal.
▷ Pressing the accelerator pedal.
