2014 BMW ACTIVE HYBRID 3 cruise control

Driving comfortVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Active Cruise Control withStop & Go function, ACC
The concept Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally 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 reduces the speed, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe‐
riod, the system is able to detect this within the
given system limits. Your own vehicle will
brake automatically and then accelerate again.
If the vehicle ahead of you drives away again
after a prolonged period, briefly press the ac‐
celerator pedal or press the appropriate button
to reactivate the system. The vehicle will auto‐
matically accelerate.
As soon as the road is clear, the vehicle accel‐
erates to the desired speed.The speed is also maintained downhill, but
may not be maintained uphill if engine power is
insufficient.
General information Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Personal responsibility
Even an active system holds the driver
responsible for his or her driving, particularly
for staying in your lane, adjusting your speed,
keeping your distance and for your driving
style all in relation to traffic.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and react when needed, e.g. through braking,
steering or make evasive maneuvers - risk of
accident.◀
Unfavorable weather conditions
In the event of unfavorable weather and
light conditions, e. g. if there is rain, snowfall,
slush, fog or glare, this may result in poorer
recognition of vehicles as well as short-term
interruptions for vehicles that are already de‐
tected. Drive attentively, and react to the cur‐
rent traffic situation. Intervene actively when
necessary, e.g., by braking, steering or making
an evasive maneuver, otherwise, there is the
risk of an accident.◀
Before leaving the vehicle, secure it
against moving on its own.
Before leaving the vehicle with the engine run‐
ning: set the parking brake and ensure that theSeite 129Driving comfortControls129

tions.
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 prevent 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.
Switching on/off and interrupting cruise control
Switching on Press button on the steering wheel.
The indicator lights in the instrument cluster
light up and the mark in the speedometer is set
to the current speed.
Cruise control can be used.
Switch off Deactivated or interrupted system
With deactivated or interrupted system
use your brakes, steering and moves as usual
to avoid the chance of an accident.◀
To switch off the system while standing, step
on brake pedal at the same time.
Press button.
▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
and distance are deleted.

InterruptingWhen active, press the button.
If interrupting the system while stationary,
press on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:▷When the brakes are applied.▷When drive mode D is removed.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to ve‐
hicles ahead of the vehicle cannot be compen‐
sated by the system for example in the follow‐
ing situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.◀Maintaining/storing the speed
Press button.
Or:
Press the rocker reel while the system is inter‐
rupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
This is displayed in the speedometer and
briefly in the instrument cluster. Displays in the
instrument cluster, refer to page 132.
When cruise control is maintained or stored,
DSC Dynamic Stability Control will be turned
on if needed.
Changing the speed
Press the rocker reel up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the vehicle reaches the stored speed when the
road is clear.
▷Each time the rocker reel is pressed to the
point of resistance, the desired speed in‐
creases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker reel is pressed past
the point of resistance, the desired speed
increases or decreases by a maximum of
5 mph/10 km/h.
Hold the rocker reel in position to repeat the
action.

When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Radar sensor
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:
▷OAYARS3-A
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
Cruise control The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions

conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding 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 vehi‐
cle and cause an accident.◀
