BMW M5 Owner's Handbook Manual page 205

Function
If fastened, the driver's and front passenger's
seat belts are automatically tensioned when driv‐
ing off.
In critical accident situations, the following indi‐
vidual functions become active as required:
▷ Automatic pre-tensioning of the front seat
belts.
▷ Automatic closing of the windows, leaving
just a small gap.
▷ Automatic closing of the glass roof, including
the sun guard.
If the critical driving situation passes without an
accident occurring, the front seat belt tension is
released again.
If the belt tension does not loosen automatically,
stop the vehicle and unfasten the seat belt by
pressing the red button on the buckle. Fasten
the seat belt again before continuing your jour‐
ney.
All other systems can be restored to the desired
setting.
PostCrash – iBrake
Principle
The system can automatically bring the vehicle
to a standstill in certain accident situations with‐
out the involvement of the driver. The risk of a
further collision and its consequences can
thereby be reduced.
At a standstill
After the vehicle has come to a halt, the brake is
released automatically.
Harder vehicle braking
In certain situations, it may be necessary to bring
the vehicle to a standstill more quickly.
To do this, for a short time the braking pressure
applied when stepping on the brake pedal must

Safety
be higher than the braking pressure achieved by
the automatic braking function. The automatic
braking process is interrupted as a result.
Cancelling automatic braking
In certain situations, it may be necessary to can‐
cel automatic braking, for example for an evasive
manoeuvre.
Cancel automatic braking:
▷ By depressing the brake pedal.
▷ By depressing the accelerator pedal.
Attentiveness assistant
Principle
The system can detect decreasing attentiveness
or tiring of the driver on long monotonous jour‐
neys, for example on motorways. In this situation,
it is recommended that you take a break.
Safety note
WARNING
The system does not relieve you of your per‐
sonal responsibility to assess your physical
condition correctly. Increasing inattention or fa‐
tigue might not be detected, or may not be de‐
tected in good time. There is a danger of acci‐
dents. Make sure that the driver is rested and
alert. Adapt your driving style to the traffic con‐
ditions.
Function
The system is switched on every time drive-
ready state is switched on.
After commencement of the journey, the system
adapts to the driver so that an decrease in atten‐
tion or fatigue can be detected.
This process considers the following criteria:
▷ Personal driving style, for example, steering.
