Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake that can be set and released
by using a button.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking
brake acts on the rear wheels via an electrome-
chanical mechanism. When the vehicle is rolling
or being driven, the parking brake acts on the disc brakes of the front and rear wheels via the
hydraulic brake system.
Setting the brake
Pull the button. The parking brake is set.
The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.

To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
In the rare case that the parking brake needs to
be used while driving, pull the button for a
lengthy period:
The vehicle brakes hard while the button is
being pulled. The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lamps light up.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
> Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
> Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
> Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
> Each time the lever is pulled beyond the
resistance point, the desired speed is
reduced by up to 5 mph o r 10 km/h until the minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow 3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
> When you brake the vehicle
> When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
> When you engage selector lever position N
in cars with an automatic transmission
> When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
> When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC.
> When DSC or ABS is intervening
Cruise control is not de activated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the st ored speed is achieved
again and maintained.

Technology for driving comfort and safety
78
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously, otherwise there is a risk
of personal injury or property damage.

Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page 112.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure st able braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressu re on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical lim its by reducing engine
output and through braking actions at the indi-
vidual wheels. The laws of physics
cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do no t reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident. <
Deactivating/activating the DSC OFF
program
The program can be de activated via Dynamic
Driving Control, refer to DSC OFF.
For better control
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
DTC Dynamic Traction Control
The concept
The DTC system and the TRACTION program
is a variant of the DSC in which forward momen-
tum is optimized.
The system ensures maximum forward
momentum on special road conditions, e.g.,
unplowed snowy roads, bu t driving stability is
limited.
It is therefore necessary to drive with appropri-
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
> When driving in slus h 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/activ ating DTC Dynamic
Traction Control
The system and program can be deactivated/
activated via Dynamic Driving Control.
