Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the key is turned. They each light up once for
different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding lamp does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

Switching off tilt alarm sensor and
interior motion sensor
>Press the button on the remote
control twice in a row.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are deactivated until
the vehicle is again unlocked and locked.
Windows
To prevent injuries, exercise care when
closing the windows and keep them in
your field of vision until they are shut.
Take the key with you when you leave the car,
otherwise children could operate the windows
and possibly injure themselves.<
Opening, closing
Ignition key in position 1 or higher:
>Press the switch downward to the resis-
tance point.
The window continues to open as long as
you press the switch.
>Press the switch beyond the resistance
point.
The window opens automatically. Press the
switch again to stop the opening move-
ment.
You can close the window in the same manner
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After switching off the ignition
You can still open or close the windows for
approx. 1 minute, as long as no one opens any
of the doors.
For convenience operation via the remote con-
trol or the door lock, refer to page19 or20,
respectively.
Pinch protection system
If the closing force exceeds a certain value while
a window is being raised, the system responds
by stopping the window and then retracting it a
short distance.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories within the win-
dows' range of movement; otherwise the pinch
protection system could be impaired.<
The closing force can change as a result
of extreme temperature fluctuations. The
window then opens slightly after closing even if
there is no obstacle within the window's travel
path. If this occurs, override the pinch protec-
tion system.<
Pulling the switch beyond the resistance point
and holding it there overrides and deactivates
the pinch protection system.
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pinch pro-
tection system must be reinitialized.
Roadster: when the convertible top has
been stored in the convertible top com-
partment for an extended period of time, e.g. in
the winter months because the hardtop was
being used, it may also be necessary to reinitial-
ize the pinch protection system.<
Ensure that the doors and the Roadster's con-
vertible top are closed before initializing.

Technology for driving comfort and safety
Driving stability control
systems
Your BMW is equipped with a series of systems
that help maintain driving stability even in
adverse driving situations.
Antilock Brake System ABS
ABS keeps the wheels from locking during
braking. Steering stability is maintained even
during full brake applications. In this way, active
safety is enhanced.
ABS is operational each time the engine is
started. Braking safely, refer to page71.
Electronic brake-force distribution
The system controls brake-force application at
the rear wheels in order to obtain increased sta-
bility in the vehicle's braking response.
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. At the same time, the benefits of the ABS
are also exploited.
As long as you want full braking to continue, do
not reduce pressure on the brake.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.
The laws of physics cannot be repealed
even with DSC. It will always be the
driver's responsibility to drive in a manner that
matches road conditions. Therefore, do not limit the additional safety margin by practicing
risky driving.<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamp for DSC lights up in the instrument
cluster. Dynamic Traction Control DTC and
DSC have been deactivated simultaneously. No
more interventions to increase stability and for-
ward momentum are carried out.
To enhance vehicle stability, reactivate DSC as
soon as possible.
Activating DSC
Press the button again; the indicator lamp goes
out in the instrument cluster.
Checking
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamp is lit:
DSC has been deactivated completely.
Dynamic Traction Control DTC
DTC is a variant of the DSC in which forward
momentum is optimized for special road condi-
tions, e.g. snow-covered roads that have not
yet been cleared. The system ensures maxi-
mum forward momentum, but driving stability is
limited. Therefore, drive carefully in accordance
with conditions.

Technology for driving comfort and safety
50 In the following exceptional circumstances, it
may be effective to activate the DTC for a short
period:
>When driving on snow-covered grades, in
slush or on uncleared, snow-covered roads
>When rocking the vehicle or starting off in
deep snow or on loose surfaces
>When driving with snow chains
Activating DTC
Press the button briefly; the DTC indicator lamp
lights up in the instrument cluster.
Checking
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
Malfunction in the driving stability
control systems
Have the system checked as soon as possible.Drive cautiously, think well ahead and
avoid full brake applications, otherwise
unstable driving conditions could result.<
The vehicle remains operational. Have the sys-
tem checked as soon as possible.
Drive cautiously and think well ahead,
otherwise unstable driving conditions
could result.<
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the handbrake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.< The indicator lamp flashes:
DTC controls the drive forces and
brake forces.
The indicator lamp is lit:
DTC has been activated.
The warning lamp for the brake system
lights up in red, together with the yel-
low indicator lamps for ABS and DSC:
The driving stability control systems
have failed.
Canadian models display these warn-
ing lamps.
The DSC warning lamp lights up
together with the yellow warning lamp
for the brake system:
DSC, including DTC and DBC, are
malfunctioning.
Canadian models display these warn-
ing lamps.

Malfunction
The warning lamp for the brake system
lights up in yellow. The drive-off assis-
tant has failed. The car will not be held
in place after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affecting the
rotational speed of the wheels. This change is
detected, and a flat tire warning is issued to the
driver.
System requirements
To ensure a reliable flat tire warning, the system
must be initialized with the correct tire inflation
pressures.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
The system could issue a false warning or func-
tion in a delayed manner in the following situa-
tions:
>System was not initialized
>Driving on a snow-covered or slippery road
surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>Driving with snow chains attached
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is continued automatically
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine immediately before pulling
away, but do not drive off yet.
2.Press the button until the yellow indicator
lamp in the instrument cluster lights up for a
few seconds.
3.Drive off.
Initialization is completed during the drive,
without any feedback issued.
Flat tire warning
The warning lamp in the instrument
cluster lights up in red. A signal also
sounds. There is a flat tire or a signifi-
cant loss of tire pressure.
1.Cautiously reduce speed to 50 mph/
80 km/h or lower. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph/80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page84, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the inflation pressure is correct in all
four tires, it is possible that the Flat
Tire Monitor was not initialized. In this case,
initialize the system.<

Technology for driving comfort and safety
52 3.In the event of complete tire pressure loss,
0 psi/0 kilopascal, you can estimate the
possible distance for continued driving on
the basis of the following guidelines:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
>With a medium load:
1 person, cargo bay full,
or
2 persons without luggage:
approx. 90 miles/150 km
>With a full load:
2 persons, cargo bay full:
approx.30miles/50km.
Drive cautiously. Do not exceed a speed
of 50 mph/80 km/h. Driving characteris-
tics change if there is a loss of tire pressure.
This includes reduced tracking stability in brak-
ing, extended braking distance and altered nat-
ural steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over to the side of the road at the
earliest opportunity. Otherwise, parts of the tire
could come loose and cause an accident. Do
not continue driving. Contact a BMW Center.<
Electric Power Steering EPS
The concept
The electric power steering is a direct, sporting
steering system. A special combination of elec-
tric motor and transmission helps you steer
more easily. As your speed increases, steering
power assistance is reduced.
Malfunction
The indicator lamp stays lit:
The system is malfunctioning or defec-
tive.
Steering remains operational.
Have the system checked as soon as possible.
Brake Force Display
The brake lamps light up in two stages,
depending on how sharply you apply the
brakes.
>Normal braking:
The brake lamps and the center brake lamp
light up.
>Sharp braking:
A larger portion of the brake lamps lights up.
Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Side airbags
3Knee airbags
Protective action
Comply with the instructions on page30,
or the occupants' personal safety will be
diminished.<
The front airbags help protect the driver and
passenger in the event of a frontal impact in
which safety belts alone cannot provide suffi-
cient protection. When needed, the side airbags
