BMW 3 SERIES 2017 Owners Manual

Safety
informationWARNING
The system does not release the driver
from the personal responsibility to correctly assess route and traffic situation. There is a
risk of an accident. Adjust the driving style to
the traffic conditions. Watch traffic closely and actively intervene in the respective situations.In the event of a warning, do not unnecessarily
jerk the steering wheel.'

'yIn the event of missing, worn, poorly visij
ble, merging, diverging, or multiple lane markings such as in construction areas.'yWhen lane markings are covered in snow,
ice, dirt or water.'yIn tight curves or on narrow lanes.'yWhen the lane markings are covered by
objects.'yWhen driving very close to the vehicle in
front of you.'yWhen driving toward bright lights.'yWhen the windshield in front of the interior
mirror is fogged over, dirty or covered with stickers, etc.'yDuring calibration of the camera immedijately after vehicle delivery.

Detection
The
concept
Two radar sensors in the rear bumper monitor
the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehij
cles in the blind spot, arrow 1, or approaching from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dimj med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sitj
uations described above.
The lamp in the exterior mirror housing flashes and the steering wheel vibrates.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess visij bility and traffic situation. There is a risk of anaccident. Adjust the driving style to the traffic
conditions. Watch traffic closely and actively intervene in the respective situations.'

Prewarning
The dimmed lamp in the exterior mirror housj ing indicates when there are vehicles in the
blind spot or approaching from behind.
Acute
warning If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the exterior mirror housing
flashes brightly.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the
critical zone.
Brief
flashing A brief flashing of the lamp during vehicle unj
locking serves as system self-test.
System
limits
Safety
information WARNING
The system can react incorrectly or not
at all due to the system limits. There is a risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.'

Brake
force
display
Concept
Additional brake lamps indicate emergency
braking to the traffic behind. This can reduce
the risk of a rear-end collision.
General
information'yDuring normal brake application, the outerbrake lights light up.'yDuring heavy brake application, the innerbrake lights additionally light up.
Attentiveness
assistant
Concept
The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, e.g., on highways. In this situation, it is
recommended that the driver takes a break.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess one's physical state. An increasing lack ofalertness or fatigue may not be detected or notbe detected in time. There is a risk of an accijdent. Make sure that the driver is rested and
alert. Adjust the driving style to the traffic conj
ditions.'

features
and
optionsThis chapter describes all standard, country-specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable country provisions
must be observed.
Anti-lock
Braking
System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle maintains its steering power even during full brake applications, thus increasing
active safety.
ABS is operational every time you start the enj gine.
Brake
assistant When you apply the brakes rapidly, this systemautomatically produces the greatest possible
braking force boost. It reduces the braking disj
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.DSC
Dynamic
Stability
Control
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reducj
ing engine speed and by applying brakes to
the individual wheels.
General
information
Dynamic Stability Control detects, e.g., the folj lowing unstable driving conditions:'yFishtailing, which can lead to oversteering.'yLoss of traction of the front wheels, which
can lead to understeering.
Dynamic Traction Control DTC, refer to
page 126, is a version of the DSC where forj
ward momentum is optimized.
Safety
information WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sysj
tem, it cannot independently react to all traffic
situations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the rej
spective situations.'

DTC
Dynamic
Traction
Control
Concept
DTC is a version of the DSC where forward
momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with somej
what limited driving stability.
When DTC is activated, the vehicle has maxij
mum traction. Driving stability is limited during acceleration and when driving in curves.
Therefore, drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:'yWhen driving in slush or on uncleared,
snow-covered roads.'yWhen freeing vehicle from deep snow or driving off from loose ground.'yWhen driving with snow chains.

xDrive xDrive is the all-wheel-drive system of your vej
hicle. Concerted action by the xDrive and DSC further optimize traction and driving dynamics.The xDrive all-wheel-drive system variably disjtributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
Dynamic
Damping
Control
Concept
This system reduces undesirable vehicle moj tion when using a dynamic driving style or travj
eling on uneven road surfaces.
This enhances the driving dynamics and drivj
ing comfort depending on the road surface
condition and driving style.
ProgramsThe system offers several different programs.
The programs can be selected via Driving Dyj namics Control.
SPORT
Consistently sporty control of the shock abj
sorbers for greater driving agility.
SPORT+ Consistently sporty control of the shock abj
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 Concept
The Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Varij
ous programs can be selected for this purpose.
The Driving Dynamics Control and the DSC
OFF buttons can each be used to activate a
program.

Servotronic
Concept
The Servotronic varies the steering force rej
quired to turn the wheels in accordance with the vehicle speed. At low speeds, the steeringforce is strongly supported, i. e. during steerjing, low force is required. As the speed injcreases, the assistance of the steering force is
reduced.
Furthermore, the steering force adapts accordj ing to the driving program, so that a direct,sporty feel and/or comfortable steering is conjveyed.Seite 130ControlsDriving
