ing.
Increase braking and distance.The vehicle flashes red and an
acoustic signal sounds: acute warn‐
ing.
You are requested to intervene by
braking or making an evasive ma‐
neuver.
Braking intervention
The warning prompts the driver himself to in‐
tervene. During a warning, the maximum brak‐
ing force is used. A prerequisite for the brake
booster is a sufficiently fast and sufficiently
strong actuation of the brake pedal. In addition,
if there is a risk of collision, the system can as‐
sist with a slight braking intervention. The in‐ tervention can bring a vehicle traveling at slow
speed to a complete stop.
Manual transmission: During a braking inter‐
vention up until reaching a complete stop, the
engine may be shut down.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
pressing on the accelerator pedal or by actively
moving the steering wheel.
Tow-starting and towing
When tow-starting and towing the vehi‐
cle, switch off the Intelligent Safety systems;
otherwise, improper behavior of the braking
function of individual systems could result in
an accident.◀
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 dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐
sued 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.▷Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, for example, DSC
OFF.▷If the camera in the mirror or the radar sen‐
sor is dirty or obscured.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant dimming because of
oncoming light, for example, from the sun
low in the sky.Seite 105SafetyControls105

Prewarning sensitivityDepending on the set prewarning time, this
may result in increased false warnings.
Collision warning withbraking function
The concept
The system issues a warning if there is immi‐
nent danger of a collision and also includes a
braking function.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the collision warning is
controlled via the cruise control radar sensor.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.
General information The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. The time
of these warnings may vary depending on the
current driving situation.
Detection range
It responds to objects if they are detected by
the radar.

Warning stages
Prewarning
This warning is issued, for example, when there is the impending danger of a collision or
the distance 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 driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by an automatic braking intervention
in a possible risk of collision.
The detection of objects can be influeneced by
technical system limitations, e. g. pedestrians
or stationary objects. Limitations of the detec‐
tion range and functional restricitions are to be
considered.
The braking intervention is executed with lim‐
ited braking force and for a brief period only.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
Above approx. 130 mph/210 km/h, the braking
intervention occurs as a brief braking pressure.
No automatic delay occurs.
Adapting your speed and driving style
The warning does not relieve the driver
of the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
The braking intervention can be interrupted by
pressing on the accelerator pedal or by actively

Detection range
The detection capability of the camera is lim‐
ited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians having a body size less than
32 in/80 cm.
Functional limitations
The system may not be fully functional or may
not be available in the following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the camera view field or the front wind‐
shield are dirty or covered.▷When driving toward bright lights.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷When it is dark outside.
Lane departure warning
The concept Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Hints Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel, as you may lose control of the vehi‐
cle.◀

Parking assistant The concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 128.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility for the
driving process.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Continuously and attentively monitor the driv‐
ing process, the area surrounding the vehicle
and the traffic situation, and actively intervene
when required, otherwise, there is a risk of an
accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.Seite 136ControlsDriving comfort136

Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.
When accelerating, shift up before reaching
high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
The gear shift indicator of your vehicle indi‐
cates the most fuel efficient gear.
Use coasting When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
On a downhill gradient, take your foot off the
accelerator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,road conditions, maintenance or environmental
factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Therefore, switch off these functions if they
are not actually needed.
The ECO PRO driving program supports the
energy conserving use of comfort functions.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 202.
ECO PRO
The concept ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort functions, e. g. the
climate control output, are adjusted.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
the D selector lever position. The vehicle con‐
tinues traveling with the engine idling to re‐
duce fuel consumption. Selector lever position
D remains engaged.Seite 169Saving fuelDriving tips169

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as the brake or accelerator pedal is
depressed, the engine is automatically coupled
to the transmission again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 169, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A forward-looking driving style helps the driver
to use the function as often as possible and supports the fuel-conserving effect of coast‐
ing.
Safety mode
The function is not available if one of the fol‐
lowing conditions is satisfied.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are satisfied:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.Seite 172Driving tipsSaving fuel172
