Safety information  
Harder vehicle deceleration  
In certain situations, it may be necessary to  
bring the vehicle to a stop more quickly than  
automatic braking with PostCrash iBrake.  
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  
To do this, quickly apply extra force to the  
brake. The brake pressure will then be higher  
than the brake pressure generated by auto-  
matic braking. Automatic braking with Post-  
Crash iBrake is canceled.  
Abort automatic braking  
It may be necessary to cancel PostCrash  
iBrake automatic braking in certain situations,  
e.g., when making an evasive maneuver.  
Function  
Depending on the equipment and require-  
ments, the following individual functions are  
active in accident-critical driving situations:  
Abort automatic braking:  
By depressing the brake pedal for slightly  
longer.  
Automatic closing of the windows.  
The windows remain open with a small  
gap.  
By pressing the accelerator pedal for  
slightly longer.  
Automatic closing of the glass sunroof.  
The sun protection is also closed.  
Fatigue alert  
Automatic positioning of the backrest for  
the front passenger seat.  
Principle  
Systems can be returned to the desired set-  
tings following a critical driving situation with-  
out accident.  
The Fatigue Alert break recommendation fea-  
ture can detect when the driver is fatigued  
or less alert during long, monotonous trips,  
for instance on highways. This function recom-  
mends taking a break.  
PostCrash iBrake  
Safety information  
Principle  
In certain accident situations, the PostCrash  
iBrake can automatically bring the vehicle to a  
standstill without intervention by the driver.  
Warning

the driver’s personal judgment in assessing  
one's physical state. An increasing lack of  
alertness or fatigue may not be detected or  
not be detected in time. There is a risk of  
accident, injury, and property damage. Make  
sure that the driver is rested and alert. Adjust  
driving style to traffic conditions.  
General information  
The PostCrash iBrake can reduce the risk of a  
further collision and its consequences.
