BMW 4 SERIES COUPE 2019 Owners Manual

Swerving
vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as your vehicle.
If a vehicle driving ahead of you suddenly swerves into your lane, the system may not be
able to automatically restore the selected disj
tance. It may not be possible to restore the sej lected distance in certain situations, including if
you are driving significantly faster than vehicles driving ahead of you, for instance when rapidly
approaching a truck. When a vehicle driving
ahead of you is reliably detected, the system rej
quests that the driver intervene by braking and
carrying out evasive maneuvers, if needed.
Unexpected
lane
change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehicle,
you yourself must react, as the system does not react to stopped vehicles.
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves canj
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
The system has a limited detection range. Situaj tions can arise in tight curves where a vehicledriving ahead will not be detected or will be dej
tected very late.
When you approach a curve the system may
briefly report vehicles in the next lane due to the bend of the curve. If the system decelerates youmay compensate it by briefly accelerating.
After releasing the accelerator pedal the system
is reactivated and controls speed independently.
Driving
away
In some situations, the vehicle cannot drive off automatically; for example:
'xOn steep uphill grades.'xFrom bumps in the road.
In these cases, step on the accelerator pedal.

The shorter the distance to the object, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 inches/25 cm, a continuous tone is
sounded.
With front PDC: if objects are simultaneously loj
cated both in front of and behind the vehicle, an alternating continuous signal is sounded.
The signal tone is switched off, when selector lever position P is engaged on vehicles with
Steptronic transmission.
Volume The ratio of the PDC signal tone volume to the
entertainment volume can be adjusted.
