Select only when the vehicle is stationary.
N Neutral
You can shift into neutral, for example, in auto-
matic car washes. The vehicle can roll.
D Drive, automatic position
Under normal operating conditions, fuel con-
sumption is the lowest when the vehicle is
driven in position D.
Kick-down
The kick-down mode provides maximum accel-
eration.
Press the accelerator pedal past the increased
resistance point at the full-throttle position.
Sport program and manual mode M/S
Move the selector lever from position D toward
the left into the M/S shifting slot.
The Sport program is activated and SD appears
in the instrument cluster. This position is rec-
ommended for a performance-oriented driving
style.
When you push the selector lever forward or
pull it back, this activates the manual mode and
Steptronic changes gear. The instrument clus-
ter shows M1 through M5.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; as a result, for
example, a downshift that would cause the
engine to overrev will not be executed by the
system. The gear selected will appear briefly in
the instrument cluster followed by the current
gear.To use the automatic function again, move the
selector lever to the right into position D.
Malfunction
The warning lamp lights up. A malfunc-
tion has occurred in the transmission
system. Avoid heavy loads.
While it will still remain possible to move the
selector lever to any desired position, the trans-
mission will revert to its default mode with only
a limited number of forward gears.
Have the system checked as soon as possible.

Technology for comfort, convenience and
safety
PDC Park Distance Control*
The concept
PDC provides extra safety and convenience
during parking maneuvers. Audible signals indi-
cate that you are approaching an object in front
of or behind your vehicle. To measure the dis-
tance, there are four ultrasonic sensors in each
bumper.
An acoustic signal begins to sound when the
front sensors and the rear corner sensors are
within approx. 2 ft/60 cm of an obstacle and
when the rear middle sensors are within approx.
5 ft/1,50 m of an obstacle.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching objects too fast; otherwise,
the system may give warning of physical obsta-
cles too late.<
If you are driving with a trailer, the rear sensors
cannot take any meaningful measurements.
Consequently, they do not switch on.
Automatic mode
In ignition key position 2, the system is auto-
matically activated after approx. one second
each time you shift into reverse or move the
selector-lever into position R. Wait for this short
time span before moving.
You can have a signal tone programmed
into the system to verify that the PDC is
active.<
Activating manual mode
In ignition key position 2, press the button; the
LED lights up.
Deactivating manual mode
Press the button again, the LED goes out.
The system is automatically deactivated once
the vehicle travels approx. 160 ft/50 m or
exceeds a speed of roughly 20 mph/30 km/h;
the LED goes out. You can reactivate the sys-
tem manually as needed.
Signal tones
An intermittent tone from a rear speaker signals
the distance to an object behind the vehicle as
you approach it.
An intermittent tone from a speaker beneath
the dashboard signals the distance to an object
in front of the vehicle as you approach it.
As the distance between vehicle and object
decreases, the intervals between the tones
become shorter. The signal tone becomes con-
tinuous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
An intermittent tone is interrupted after approx.
3seconds:
>if y o u r e m a in i n f ro n t o f a n o b j e c t t ha t is o n ly
detected by one of the corner sensors
>if you are moving parallel to a wall

Technology for comfort, convenience and safety
48
Malfunction
The LED in the button flashes and a short con-
tinuous tone sounds. PDC is malfunctioning.
Switch off PDC. 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.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can come into the
blind spot of the sensors before a continuous
tone sounds. The system may fail to detect
higher obstacles such as ledges.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability even under unfavorable driving
conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during full braking. This results in an
increase in the active safety.
ABS is operational every time you start the
engine. Safe braking, refer to page78.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
DBC Dynamic Brake Control
When the brake pedal is depressed quickly, this
system automatically generates a maximum
braking force distribution and thus helps keep
the braking distance to a minimum during full
braking. This system exploits all of the benefits
provided by ABS.
As long as you want full braking to continue, do
not reduce pressure on the brake.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when
starting off and accelerating. DSC also detects
unstable driving conditions, such as a fishtailing
of the vehicle's rear end or the sliding of the
vehicle on its front wheels. In these circum-
stances, DSC helps keep the vehicle on a safe
path, within physical limits, by reducing engine
output and by applying the brakes in individual
wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not reduce the additional safety mar-
gin again by taking unnecessary risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
When the indicator lamp flashes:
DSC is controlling the drive and braking forces.
When the indicator lamp stays lit:
DSC has been switched off with the button.
