Dynamic Stability Control Dsc; Driving Stability Control Systems - BMW 318i Owner's Handbook Manual

operate reliably. When using a high-pressure
cleaner, do not spray the sensors for extended
periods of time and only from a distance of at
least 10 cm, approx. 4 in.

System limitations
PDC is no substitute for your personal
assessment of obstructions. The sensors
have certain dead areas in which objects cannot
be detected. In addition, the identification of
objects may not be possible if the physical lim-
its of the ultrasonic measuring principle are
exceeded, for instance with trailer noses and
hitches, and thin or wedge-shaped objects.
Low objects already indicated, such as kerbs,
may enter the sensors' dead areas before or
after a continuous audible signal is given.
Higher, protruding objects such as ledges may
not be detectable. Loud sound sources outside
or inside the car can drown out the PDC sig-
nal.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Anti-lock Brake System ABS
ABS prevents the wheels from locking when
the brakes are applied. The car remains steera-
ble even under full braking. This increases
active safety.
ABS is ready to operate each time the engine is
started. Safe braking, see page 107.
Electronic Brake Force Distribution
EBV
The system regulates the braking pressure on
the rear wheels in order to stabilise the braking
behaviour.

Dynamic Brake Control DBC
If the brake is pressed down rapidly, this system
automatically boosts the braking force to a
maximum and thus helps to keep the braking
distance as short as possible when a full brake
application is made. It also makes full use of the
advantages offered by ABS.
Maintain pressure on the brake as long as full
braking is required.

Dynamic Stability Control DSC

DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. DSC also recognises unstable driving
conditions, for example if the rear of the car is
about to swerve or if momentum is acting at an
angle past the front wheels. In these cases DSC
reduces engine output and applies the brakes
at individual wheels, helping, within the limits
imposed by the laws of physics, to keep the car
safely on course.
Not even DSC can overcome the laws of
physics. It is therefore the driver's
responsibility to adopt a suitable driving style in
every situation. Do not undermine the addi-
tional safety afforded by this system by taking
driving risks as otherwise there is a danger that
accidents might occur.<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lights for DSC in the instrument cluster
light up. Both Dynamic Traction Control DTC
and DSC are deactivated. The stabilising and
traction-improving effects are no longer availa-
ble.
