PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones and a visual display
* indicate
the current distance to an object behind or
in front of your vehicle. To measure the dis-
tance, there are four ultrasonic sensors in
each bumper. The sensors at the front and
at the two rear corners have a range of
approx. 20 in/50 cm; the rear middle sen-
sors have 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,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic mode
In ignition key position 2, the system auto-
matically assumes operational status after
a few seconds each time you engage
reverse gear or selector-lever position R.
Wait this short period before driving.<
The system is automatically deacti-
vated once the vehicle travels approx.
165 ft/50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Manual mode
With the ignition key in position 2, press the
button; the indicator lamp lights up.
Deactivating manual mode
Press the button again; the indicator lamp
goes out.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle 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. The signal tone becomes continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds if you are moving paral-
lel to a wall.
Malfunctions
The indicator lamp within the button
flashes and a message appears on the
Control Display. PDC has failed. Switch off
PDC. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to
ensure that they will continue to operate
effectively.
PDC with visual warning*
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front pas-
senger
2Coupe: head airbags
3Front side airbags
4Knee airbag for front passenger
5Knee airbag for driver
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone can-
not provide adequate restraint. When
needed, the head and side airbags help
provide protection in the event of a side
impact. The side airbags help restrain the
side of the occupant's upper torso, and the
head airbags help support the head while
also helping provide protection against any
objects penetrating into the passenger
compartment.
The airbags are deliberately not triggered
in every impact situation, e.g. less severe
accidents, certain rollover conditions, or
rear-end collisions.
For information on the correct sitting posi-
tion, refer to page 42.
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild hearing loss in
extremely sensitive individuals. This effect
is usually only temporary.Do not apply adhesive materials to
the cover panels of the airbags, cover
them or modify them in any other way.
Do not attempt to remove the airbag reten-
tion system from the vehicle. Never modify
or tamper with either the wiring or the indi-
vidual components in the airbag system.
This category includes the upholstery in the
center of the steering wheel, on the instru-
ment panel, the side trim panels on the
doors and on the Coupe the roof pillars
along with the sides of the headliner.
Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been trig-
gered, because there is a danger of burns.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem is triggered in response to an accident,
you should always entrust all inspection,
repair and dismantling operations to your
BMW center. Unprofessional attempts to
service the system could lead to failure in
an emergency or undesired airbag activa-
tion, either of which could result in personal
injury.<
Airbag warning information is also provided
on the sun visors.

Airbag system operational
The airbag warning lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The warning lamp goes out after a few sec-
onds.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem not responding in the expected man-
ner to an impact occurring within its normal
response range.<
There is a malfunction in the airbag
system when:
>The warning lamp does not light up as
of ignition key position 1
>The warning lamp remains on continu-
ously
>The warning lamp lights up while the
vehicle is being driven.

Rollover protection system
The rollover protection system is automati-
cally activated in the event of an accident
or a critical driving situation, extreme incli-
nation on the longitudinal or transverse
axis, or loss of ground contact. The rollover
bars located behind the rear head
restraints move out within fractions of a
second.As a supplement to the rollover bar inte-
grated in the windshield frame, the rollover
protection system ensures that all vehicle
occupants have the necessary headroom.
Always keep the path of movement of
the rollover protection system clear.
In less severe accidents, you are protected
by the fastened safety belt and, depending
on the severity of the accident, the belt ten-
sioner and the multistage airbag restraint
system.<
Lowering
If the protection function was not required
after automatic activation, the rollover pro-
tection system can be lowered again.
No tools are necessary for this purpose.
1.Press the release backwards and hold
in that position
2.Press the rollover bar halfway down
from above
3.Let go of the release
4.Press the rollover bar down until it
snaps into place
5.Use the same procedure for the second
rollover bar.
Have the rollover protection system
checked after unexpected triggering.

No changes of any nature may be made to
the individual components of the rollover
protection system and wiring.
Work on the rollover protection system may
only be performed at a BMW center.
Unprofessional attempts to service the sys-
tem can lead to failure or malfunction.
For a system check and to ensure long-
term functioning, you must comply with the
maintenance intervals of the service
requirement display.<
