2015 BMW 4 SERIES CONVERTIBLE Automatic lock

Driving stability control systemsVehicle features and optionsThis 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. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power 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 greatest possible
braking force boost. It reduces the braking dis‐
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
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note 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The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving with
roof load
Do not deactivate Dynamic Stability Control DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

When using the automatic climate control,
condensation water, refer to page 170, devel‐
ops that exits underneath the vehicle.
Recirculated-air mode You may respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently
within the vehicle.
Press button repeatedly to select an
operating mode:▷LED off: outside air flows in continuously.▷LED on, recirculated-air mode: the supply
of outside air into the vehicle is perma‐
nently blocked.
Recirculated air mode switches off automati‐
cally at low external temperatures after a cer‐
tain amount of time in order to avoid window
fogging.
If the windows fog over, switch off recircu‐
lated-air mode and increase the air flow, if
needed.
Sufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
culated-air mode; otherwise the air quality in
the interior continuously deteriorates and win‐
dow condensation increases.◀
Switching the system on/off Switch off Press the left button for the minimumspeed.
Switching on
Press any button except▷Rear window defroster.▷Seat heating.
Microfilter
In external and recirculated air mode the mi‐
crofilter filters dust and pollen from the air.
This filter should be replaced during scheduled
maintenance, refer to page 205, of your vehi‐
cle.

▷Left LED on, automatic recirculated-air
control: a sensor detects pollutants in the
outside air and shuts off automatically.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
Recirculated air mode switches off automati‐
cally at low external temperatures after a cer‐
tain amount of time in order to avoid window
fogging.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO
button to utilize the condensation sensor.
Make sure that air can flow to the windshield.
Sufficient ventilation
When remaining in the vehicle for an ex‐
tended period of time, ensure sufficient exter‐
nal ventilation. Do not continuously use recir‐
culated-air mode; otherwise the air quality in
the interior continuously deteriorates and win‐
dow condensation increases.◀
Manual air distribution Press button repeatedly to select a
program:
▷Upper body region.▷Upper body region and footwell.▷Footwell.▷Windows and footwell: driver's side only.▷Windows, upper body region and footwell:
driver's side only.
If the windows are fogged over, press the
AUTO button to utilize the condensation sen‐
sor.
Air flow, manual
To manually adjust air flow turn off AUTO pro‐
gram first.
Press the left or right side of the but‐
ton: decrease or increase air flow.
The selected air flow is shown on the display of
the automatic climate control.
The air flow of the automatic climate control
may be reduced automatically to save battery
power.
Rear window defroster Press button.
The rear window defroster switches
off automatically after a certain period of time.
Defrosts windows and removes
condensation
Press button.
Ice and condensation are quickly re‐
moved from the windshield and the front side
windows.
For this purpose, point the side vents onto the
side windows as needed.

If the windows are fogged over, you can also
switch on the cooling function or press the
AUTO button to utilize the condensation sen‐
sor.
Switching the system on/off
Switch off Press the left button for the minimum
