Alarm system
The concept
The vehicle alarm system responds:
>
When a door, the hood or the trunk lid is
opened
> To movements inside the vehicle: Interior
motion sensor, refer to page 38
> When the car's inclination changes, for
instance if an attempt is made to jack it up
and steal the wheels or to raise it prior to
towing away
> When there has been an interruption of
power supply from the battery
The alarm system signals unauthorized entry
attempts for a short time by means of:
> An acoustic alarm
> Switching on the hazard warning flashers
> Flashing the high beams
Arming and disarming
General information
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
Door lock with armed alarm system
In some national-market versions, unlocking via
the door lock tr iggers the alarm.
To switch off this alarm, unlock the vehicle with
the remote control or sw itch on the ignition.
Trunk lid with the alarm system armed
The trunk lid can be opened via the remote con-
trol even when the alarm system is armed.
Press the button on th e remote control for
approx. 1 second.
The trunk lid is locked and monitored again as
soon as it is closed.
Panic mode
You can trigger the alarm system if you find
yourself in a dangerous situation:
Press the button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
> Unlock the car with the remote control, refer
to page 32.
> Insert the remote contro l all the way into the
ignition lock.
Indicator lamp on inside mirror
> The indicator lamp fl ashes continuously:
The system is armed.
> The indicator lamp flashes after locking:
The doors, hood, or trunk lid are not prop-
erly closed, the remaining components are
secured.
Then the indicator lamp flashes continu-
ously after approx. 10 seconds. The interior
motion sensor and tilt sensor are not active.
> The indicator lamp goes out after unlocking:
The vehicle has not been tampered with.
> If the indicator lamp flashes after unlocking
until the remote contro l is inserted in the
ignition, but for no longer than approx.
5minutes:
The vehicle has been tampered with.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. to attempts to steal a wheel
or tow the vehicle.

ControlsOpening and closing
Interior motion sensor
Coupe
For proper function, the windows and glass
sunroof must be closed.
Convertible
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys-
tem is activated togeth er with the interior
motion sensor even if the hardtop is open. The
alarm can be triggered un intentionally by falling
objects such as leaves, refer to Avoiding unin-
tentional alarms.
Avoiding uninten tional alarms
The tilt sensor and interior motion sensor can
be deactivated together, for example in the fol-
lowing situations:
> In car washes
> In stacking garages
> During transport on car-carrying trains,
boats/ships or on a trailer
> When leaving animals in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Once the vehicle is locked, press the
button on the remote control again
within approx. 10 seconds.
The indicator lamp light s up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the next time the vehicle is unlocked and subse-
quently locked again.
Comfort Access
The concept
It is possible to access the vehicle without actu-
ating the remote control. It is sufficient to have
the remote control with you, for example in your
jacket pocket. The vehicle automatically
detects the remote control in the vicinity or in
the passenger compartment.
Comfort Access supports the following func-
tions:
> Unlocking/locking the vehicle
> Convenient closing
> Unlocking the trunk lid separately
> Engine starting
Functional requirement
>There are no external sources of interfer-
ence in the vicinity.
> The remote control must be outside the
vehicle to lock it.
> The next unlocking and locking cycle is not
possible until after approx. 2 seconds.
> It is only possible to start the engine if the
remote control is inside the vehicle.
Comparison to the standard remote
control
The above functions can be controlled by
pressing the remote control buttons or by using
Comfort Access.
If you notice a brief delay while opening or
closing windows, the glass roof or retract-
able hardtop, the system is checking whether a
remote control is inside the vehicle. Please
repeat the opening or closing procedure, if nec-
essary. <

Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Park Distance Control PDC
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator warn you of the presence of an object
in front of or behind your vehicle. To measure
the distance, there are four ultrasonic sensors
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the front sensors and rear corner sensors,
or approx. 5 ft/1.50 m from the rear center sen-
sors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually th e case when parking.
Avoid approaching an object at high speed; oth-
erwise, physical circumstances may lead to the
system warning being issued too late. <
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. one
second when you shift into reverse or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Switching on manually
When parking in the forward direction, the sen-
sors must be switched on manually to enable
them to signal an approach to an object in front
of or behind the vehicle.
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, if an object is dete cted behind the vehicle,
the signal tone sounds from the rear. As the dis-
tance between vehicle an d object decreases,
the intervals betwee n the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds
> If you remain in front of an object that has
been detected by only one of the corner
sensors
> If you are driving parallel to a wall.

Technology for driving comfort and safety
Controls
Malfunction
The warning lamp lights up. A mes-
sage appears on th
e Control Display.
PDC is malfunctioning. Have the sys-
tem checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to op erate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 1 ft/30 cm.
Manual operation
The LED above the button also flashes.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limit s that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously; otherwise, there is a risk of personal
injury or property damage.
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.
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.
The ABS is operational every time you start the
engine. Braking safely, refer to page140.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable 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 aw ay 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 limits by reducing engine
output and through brakin g 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 not reduce the additional
