BMW 520D User Manual

Driving

cle until it has moved entirely into the same lane
as your car.

If a vehicle ahead suddenly swerves into
your lane, the system may not always be

able to maintain the selected distance automat-
ically. The same applies to high differences
between your speed and that of preceding vehi-
cles, e.g. when rapidly approaching a truck.
Once the system has established that a vehicle
is indeed in front of you, it will indicate that you
must brake and/or manoeuvre the car yourself.
You will need to intervene to avoid the risk of an
accident.

Bends in the road

If the desired speed selected is excessive for a
bend, the system will reduce the speed while
the car is taking the bend. However, it is unable
to anticipate how sharp a bend in the road is.
You should therefore select an appropriate
speed before entering a bend.
Due to the wheel sensor's restricted range, the
situation may arise where a preceding vehicle
may not be detected on a bend in the road, or
detected very late.

When your car is approaching a bend, in view of
its curvature the system may respond tempo-
rarily to vehicles in the other lane. If your car

decelerates in such a situation, the accelerator
can be used briefly to counteract this effect.
When the accelerator is released again, the sys-
tem will resume control of the car's speed.

Your responsibility

Your actions have priority at all times. When you
press the accelerator pedal while driving with
Active Cruise Control, the automatic braking
function will be temporarily interrupted. When
the accelerator is released, the desired speed is
re-established or the selected distance from
the vehicle in front taken into account.

Do not leave your foot on the accelerator
pedal, and make sure that no objects

such as floor mats are resting on the accelerator
pedal, otherwise the system will not be able to
brake the car.
