2014 BMW 3 SERIES SEDAN wheel

Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. This then reduces braking dis‐ tance to a minimum during full braking. This
system utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Steering and, depending on the equipment,
the chassis are adjusted for sporty driving.
Activating DSC Press the button.Seite 114ControlsDriving stability control systems114

DSC OFF and the DSC OFF indicator lamp go
out.
Indicator/warning lamps When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC Press the button.
TRACTION is displayed in the instrument clus‐
ter and the indicator lamp for DSC OFF lights
up.
Deactivating DTC Press the button again.
TRACTION and the DSC OFF indica‐
tor lamp go out.
xDrive xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
Dynamic Damping Control
The concept This system reduces undesirable vehicle mo‐tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs The system offers several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 116.
SPORT Consistently sporty control of the shock ab‐
sorbers for greater driving agility.Seite 115Driving stability control systemsControls115

SPORT+Consistently sporty control of the shock ab‐
sorbers for greater driving agility when driving
with limited driving stabilization.
COMFORT/ECO PRO
Balanced control of the vehicle.
Variable sport steering The variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.
Driving Dynamics Control
The concept The Driving Dynamics Control can be used to
adjust the certain characteristics of the vehicle.
Various programs can be selected for this pur‐ pose. The Driving Dynamics Control and the
DSC OFF buttons can each be used to activate
a program.

Radar sensor
A radar sensor is located in the front bumper
for detecting vehicles on the road ahead of the
vehicle.
A dirty or covered sensor may hinder the de‐
tection of vehicles.
▷If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.▷Do not cover the view field of the radar
sensor.

Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles driving ahead of you
for instance might not be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity, you should be alert at all times so that
you can intervene if necessary; otherwise,
there is the danger of an accident occurring.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane,
e.g., a vehicle at a red traffic light or at the end
of traffic congestion.
The system also does not respond to:
▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Stationary objects.▷Cross traffic.▷Oncoming traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle. You must react yourself; otherwise,
there is the danger of an accident occurring.◀
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if necessary. You must react yourself;
otherwise, there is the danger of an accident
occurring.◀
Unexpected lane change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehi‐
cle, 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 in the curve, although
curves cannot be anticipated in advance.
Therefore, drive into a curve at an appropriate
speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not
be detected at all, or not until after a consider‐
able delay.
When approaching a curve, the system may
react briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines or
behind bumps in the road.
