System Limitations - BMW 318i Owner's Handbook Manual

Malfunction
The warning light comes on when the
system has failed. You can find more
information starting on page 142.

System limitations

The detection range of the radar sensor and
automatic braking capacity are limited. It is pos-
sible, for example, that two-wheelers in front of
you are not recognised.
The system does not decelerate your car
when a standing obstacle is in the same
Swerving vehicles
When a vehicle from a neighbouring lane
swerves into the lane in front of you, the system
does not detect the car until it is fully in the
same lane.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to maintain the selected distance automatically.
The same applies when you are driving signifi-
cantly faster than the vehicle in front of you, e.g.
when you are rapidly approaching a lorry. There
is a risk of collision. Once the system has estab-
lished that a vehicle is indeed in front of you, it
will indicate that you must brake and/or
manoeuvre the vehicle yourself. Take the

is a risk of accident.<
Characteristics in bends
If the desired speed chosen is too high for a
bend, the system reduces the speed while cor-
nering. It cannot, however, detect bends in
advance. Therefore, choose a suitable speed
well before entering a bend.
Due to the radar sensor's limited detection
range, bends may lead to vehicles ahead being
detected only later or not at all.
