Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
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 momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der 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 instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC
Press the button again.
TRACTION and the DSC OFF indicator
lamp go out.
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 two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 106.
SPORT
Consistently sporty control of the shock absorb‐
ers for greater driving agility.
SPORT+
Consistently sporty control of the shock absorb‐
ers for greater driving agility when driving with
limited driving stabilization.
COMFORT
Balanced control of the vehicle.
Variable sport steering
The variable sport steering increases the steer‐
ing angle of the front wheels at large steering
wheel angles, e.g., in tight curves or when park‐
ing. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.

Vehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Active Cruise Control with
Stop & Go function, ACC
The concept
This system can be used to select a desired
speed that the vehicle will maintain automati‐
cally on clear roads.
To the extent possible, the system automatically
adjusts the speed to a slower vehicle ahead of
you.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
If the vehicle ahead of you brakes to a halt, the
system is able to detect this within the given
system limits. If the vehicle ahead of your drives
away again from a halt, your vehicle is able to
accelerate if operated accordingly.
Even if some time passes before the vehicle
drives away again, the BMW can still be accel‐
erated automatically and simply.
As soon as the road is clear, it accelerates to the
desired speed.
The speed is also maintained on downhill gra‐
dients, but may not be maintained on uphill
slopes if engine power is insufficient.

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 actively, 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 similarly slow road users.
▷Red traffic lights.
▷Stationary objects.
▷Cross traffic.
▷Approaching 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 vehi‐
cle driving ahead of you is reliably detected, the
system requests that the driver intervene by
braking and carrying out evasive maneuvers, 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 vehicle,
you yourself must react, as the system does not
react to stopped vehicles.

rently in use.
Configuring the warning time
After the warning function is switched on, the
warning time can be set via the iDrive. For a late
warning time, prewarning is deactivated.
These settings have no effect on the time of the
warning from the Active Cruise Control that
prompts the driver to intervene or brake.

the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and ready
to intervene; otherwise, there is the danger of an
accident occurring.◀
Detection range
The detection capacity of the camera and the
collision warning has limitations.
This may result in the warning not being issued
or being issued late.
For example, the following situations may not be
detected:
▷Slow moving vehicles when you approach
them at high speed.
▷Vehicles that suddenly swerve in front of you
or sharply decelerating vehicles.
▷Vehicles with an unusual rear appearance.
▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snowfall.
▷In tight curves.
▷If the camera view field or the front wind‐
shield are dirty or covered.
▷When driving toward bright lights.
▷In the case of vehicles with insufficiently visi‐
ble tail lamps.
▷In the case of partially covered vehicles.
▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.
▷During the calibration process of the camera
immediately after vehicle shipment.
Prewarning sensitivity
Depending on the set prewarning time, this may
result in increased false warnings.

Camera
The camera is located near the base of the mir‐
ror.
Keep windshield clean and clear in the area in
front of the interior rear view mirror.
Collision warning with
braking function
The concept
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor.
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h. The time of these warnings
may vary depending on the current driving sit‐
uation.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.

Cruise control
The concept
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, for instance:
▷On curvy roads.
▷In heavy traffic.
▷On slippery roads, in fog, snow or rain, or on
a loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.◀

Side View
The concept
Side View provides an early look at cross traffic
at blind driveways and intersections. Road users
concealed by obstacles to the left and right of
the vehicle can only be detected relatively late
from the driver's seat. To improve visibility, two
cameras in the front of the vehicle record the
traffic situation on each side.
Capturing the image
Two cameras integrated in the bumpers capture
the image.
The cameras capture a maximum range of
330 ft/100 m.
Display
The images from both cameras are shown si‐
multaneously on the Control Display.
Check the traffic situation as well
Check the traffic situation around the ve‐
hicle on blind driveways and intersections with
your own eyes. Otherwise, an accident could re‐
sult from road users or objects located outside
the picture area of the Side View cameras.◀
