Cruise control*
The concept
The cruise control with a braking function is
available for use at speeds of approx. 20 mph/
30 km/h and higher. The vehicle stores and
maintains the speed that you set using the lever
mounted on the steering column. To keep the
specified speed constant, the system brakes if
the engine braking effect is not sufficient on a
downhill grade.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic o r in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise you could lose control of the vehicle
and cause an accident.<

Maintaining current speed
Briefly press, arrow1, or briefly pull, arrow2
lever.
The speed currently being driven is stored and
maintained. It is indicated on the speedometer
and briefly in the instrument panel.
The controlled speed can drop on uphill grades
if the engine output is insufficient. If the engine
braking effect is not sufficient on a downhill
grade, the system lightly brakes the vehicle.
Increasing speed
Repeatedly press the lever up to or beyond the
resistance point, arrow1, until the desired
speed is set.
>Each time the lever is pressed to the resis-
tance point, the speed is increased by
approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed
increases by a maximum of 5 mph or
10 km/h.
The system stores the setting and maintains
the set speed.
Accelerating with lever
Accelerate slightly:
Press the lever up to the resistance point,
arrow1, until the desired speed is reached.
Accelerate more rapidly:
Press the lever beyond the resistance point,
arrow1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores the
setting and maintains the set speed.
Reducing speed
Repeatedly pull the lever up to the resistance
point or beyond, arrow2, until the desired
speed is displayed.
>Each time the lever is pulled up to the resis-
tance point, the desired speed decreases
by approx. 1 mph or 1 km/h.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
However, an acoustic warning first sounds for
the sensors at the front and at the two rear cor-
ners at approx. 24 in/60 cm, and for the center
rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed, oth-
erwise the physical circumstances would mean
that the system warning was too late.<
Automatic activation
Whenever the engine is running or the ignition
is on, each time you move the selector lever into
position R, the PDC system is activated after
approx. 1 second.
Wait this short period before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
Signal tones
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a signal tone from the left
rear speaker, etc. As the distance between
vehicle and object decreases, the intervals
between the tones become shorter. If the dis-
tance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive parallel to a wall
Adjusting
You can adjust the volume of the warning tones
if the vehicle is equipped with a single drive,
refer to page80.
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.

Manually
Press the button again; the LED goes out.
Driver assistance functions
The following functions can improve the effect
of the rear view camera depending on the situa-
tion.
They can only be activated when the liftgate is
completely closed.
Pathway lines
The pathway lines are shown in the picture of
the rear view camera. They help you to estimate
the space required when parking and maneu-
vering on level roads.
To estimate the space required, turn the steer-
ing wheel so that the pathway lines guide into
the parking space or the maneuvering area you
have chosen.
The pathway lines are dependent on the current
steering angle and are continuously adjusted to
the steering wheel movements.
Turning lines
The static turning lines are displayed in the pic-
ture of the rear view camera and show you the
course of the smallest possible turning circle on
level roads.

Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
ABS is operational every time you start the
engine. Braking safely, refer to page127.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.

Technology for comfort, convenience and safety

Brake assistant
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 pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions in the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style remains the responsibility of the driver.
Therefore, do not restrict the additional safety
margin with a risky driving style, as otherwise
there is a risk of an accident.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument panel lights up, but not longer
than approx. 10 seconds. DTC Dynamic Trac-
tion Control and DSC are deactivated together.
Stabilizing interventions are now not carried
out.
A message appears on the Control Display.
Please note any supplementary information
that appears there.To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button; the indicator lamp in the
instrument panel goes out.
For better control
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamps light up:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving in sand, on snowy inclines, in
slush or on unplowed, snow-covered road
surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow, sand or on loose
ground
>When driving with snow chains

Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument panel lights up.
