Press and hold button +:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
maintains and stores the current speed.
If on a downhill gradient the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button – briefly:
If you are already driving with activated
cruise control, the speed is decreased
by approx. 0.6 mph / 1 km/h every time
you tap the button.
Press and hold button –:

Outside temperatureYou can change the units of measure,
7/6, for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active. The
units of measure, 7/6, in the temper-
ature display of the automatic climate
control change automatically, refer to
page 104.Ice warningIf the outside temperature drops to
about 37.57/+36, then the computer
will automatically switch to a display of
the outside temperature. In addition, a
signal sounds as a warning and the dis-
play flashes for a brief period.

89
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57/+36, on
bridges or shaded road surfaces, for
instance.<
Average fuel consumptionIf you press the onboard computer but-
ton BC in the turn signal lever for longer
while the average fuel consumption is
being displayed, a new consumption
value is calculated from that point in
time.
If you wish, you can have the aver-
age fuel consumption displayed in
a different unit of measure. based on the available fuel. The amount
of fuel remaining in the tank is mea-
sured, the estimated range is calcu-
lated taking into account the operating
conditions over the last 20 miles/30 km.
It is important that you refuel when
the cruising range falls below
approx. 35 miles/50 kilometers. Other-
wise, the engine cannot be guaranteed
to operate properly and damage may
result.<
Average speedAny time spent when the vehicle is sta-
tionary and the engine is shut off is
ignored for the calculation.
To reset the average speed: press the
onboard computer button BC in the
turn signal lever for approx. 2 seconds.

Dynamic Stability Control (DSC)The conceptDSC supports 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.
Indicator and warning lamps for
Canadian models.
Deactivating the DSC/activating
the DTCTap the DSC button; the indicator 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
DTCPress the DSC button as long as you
need to until the indicator lamp and the
yellow brake warning lamp light up, but
no more than 10 seconds.
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. 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, refer to page 130,
and correct 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, but no more than 10 seconds,
until the indicator lamp in the instru-
ment cluster lights up in yellow 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 157.
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
