BMW 550i xDrive Sedan 2014 - Manual (Page 127)

After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:
▷ When the clock is set incorrectly.
▷ When the vehicle speed is mainly below
about 43 mph/70 km/h.
▷ With a sporty driving style, such as during
rapid acceleration or when cornering
quickly.
▷ In active driving situations, such as when
changing lanes frequently.
▷ When the road surface is poor.
▷ In the event of strong side winds.
PreCrash
The concept
With this system critical driving situations that
might result in an accident can be detected
above a speed of approx. 20 mph/30 km/h. In
these situations, preventative protection
measures are automatically undertaken to
minimize the risk in the event of an accident as
much as possible.
Critical driving situations may include:
▷ Full brake applications.
▷ Severe understeering.
▷ Severe oversteering.
If the vehicle includes the collision warning or
collision warning with braking feature, impend‐
ing collisions with vehicles driving ahead or
stopped in front of you can also be detected
within the system's range.
Note
Personal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways detect critical situations reliably and in a
timely manner. Adapt speed to traffic situation
and drive alertly; otherwise, a risk to safety may
result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:
▷ The front belts are automatically preten‐
sioned.
▷ Automatic closing of the windows.
▷ Automatic closing of the glass sunroof.
▷ For vehicles equipped with Comfort Seats:
automatic positioning of the backrest for
the front passenger seat.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the ve‐
hicle to brake harder. This interrupts automatic
braking. Depressing the accelerator pedal also
interrupts automatic braking.
