The entire ABS, CBC and DSC
control system has failed. Con-
tinue driving cautiously and
defensively. Avoid full brake
applications. Please have the system
checked by your BMW center as soon
as possible.

Opening and closing1To close
2To open
To avoid placing unnecessary
loads on the battery, you should
avoid operating the top when the
engine is switched off.
Before closing the top, always ensure
that the windshield frame is clear of any
obstructions that could prevent the top
from closing correctly.<
With the ignition key in position 1 or
higher, and with the vehicle stationary
1. Read and comply with the preceding
safety precautions
2. Ensure that the convertible top com-
partment panel in the luggage com-
partment is folded down, see
page 37; otherwise, it will not be
possible to open the convertible top
3. Ensure that the luggage compart-
ment lid is closed
4. Maintain pressure on the corre-
sponding button for the convertible
top operation.
The luggage compartment lid can-
not be opened while the convert-
ible top is in motion.<
While the convertible top is in
motion, the rear window will move
toward the passenger compartment. To
avoid possible pinching, the area
around the closing convertible top
should be clear.<
After having been stored for an
extended period of time in the
convertible top compartment, e.g. dur-
ing the winter months because the
hardtop was being used, you may have
to support the convertible top by hand
when closing it for the first time.
If the convertible top should halt just
before the closing phase is completed,
press against the front section of the
convertible top frame from the outside
to help the closing process along. Con-
tinue pressing the switch while doing
so until the top starts up again on its
own.<
Indicator lamps>The red indicator lamp is lit whenever
the convertible top mechanism is in
motion. It goes out as soon as the
opening or closing operation has
been completed
>If the red indicator lamp flashes after
the control button is released, the
convertible top has not yet been
opened or closed completely. You
can resume operation in the desired
direction by pressing the button
again
>If the yellow indicator lamp lights up
continuously with the button pressed,

Dynamic Stability Control (DSC)The conceptDSC maintains vehicle stability, even in
critical driving situations.
DSC is operational every time you start
the engine.
DSC contains the Dynamic Traction
Control (DTC) and Cornering Brake
Control (CBC) functions.Indicator lamps
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 19.
>The indicator lamp flashes: DSC is
actively controlling drive torque and
braking intervention
>The indicator lamp stays lit: DSC has
been switched off with the button;
DTC and DBC are operational. DTC
control intervention is not indicated.
The indicator lamp and the
brake warning lamp continu-
ously light up in yellow:
The DSC, DTC and DBC have
been switched off manually or
there is a system malfunction.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center.

Canadian models.
Deactivating the DSC/activating
the DTCPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is deactivated; DTC is operational.
In the following rare situations, it may
prove useful to activate the DTC for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.

Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.Deactivating the DSC and the
DTCHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamp light up and
remain on continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC acti-
vated whenever possible. lamp or the indicator lamps will go out.
DTC is deactivated.
The laws of physics cannot be
repealed even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the sys-
tem as an excuse for taking risks.
Whenever the DTC is activated, the
DSC is switched off and performs minor
stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 25 and cor-
rect them, if necessary
3. Initialize the system.

System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 153.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h

Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside, refer to Run
Flat tires, page 156.<
2. To continue driving, follow the
instructions under Driving with a
damaged tire on page 157.
System malfunction
The indicator lamp in the instru-
ment cluster lights up yellow.
The Flat Tire Monitor is malfunc-
tioning or out of order. Please refer the
problem to your BMW center.
Brake force displayThe brake force display indicates to the
driver of the vehicle behind you how
hard you are braking your vehicle.
The display has two levels:
>Normal braking: the brake lamps
among the rear lamps and the center
brake lamp light up
>Hard braking or use of ABS: the tail
lamps light up with the same bright-
ness as the brake lamps and thereby
intensify the visual effect of the brake
lamps.
