Cruise controlYou can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h).
Refrain from using the cruise
control on twisting roads, when
high traffic density prevents driving at a
constant speed, and when driving on
slippery (snow, rain, ice) or loose
(gravel, sand) road surfaces.<520de061
Store and maintain
speed/acceleratePress the lever briefly in direction 1:
The system maintains the current
vehicle speed. Every time you briefly
press the lever, the speed increases by
approx. 0.6 mph (1 km/h).
Press and hold the lever in position 1:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the lever, the system main-
tains the current speed.
The vehicle may accelerate
beyond the preselected speed on
steep downhill stretches, where engine
braking alone may not be enough to
slow the vehicle. It can also slow when
the engine fails to maintain the prese-
lected speed when ascending steep
grades.< To decelerate Press the lever briefly in direction 2:
With the cruise control active, the
speed decreases by approx. 0.6 mph
(1 km/h) every time you briefly touch the
lever.
Press and hold the lever in position 2:
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the lever, the system
registers and maintains the current
speed. To cancel the cruise controlPress the lever briefly in direction 3:
The cruise control is immediately
canceled.
In addition, the system automatically
deactivates in response to the following
conditions:
>braking
>clutch disengagement
>when vehicle speed deviates from
the preset speed for an extended
period, for instance, as a result of
pressure on the accelerator pedal. To deactivate the system Turn ignition key to position 0.

The conceptDSC maintains vehicle stability even in
critical driving situations.
DSC maintains optimal, predictable
response while maximizing traction
when you accelerate from a standing
start or speed up while already
underway. The system recognizes any
tendency for the vehicle to assume an
instable attitude such as oversteer and
understeer, and counteracts this
tendency with a combination of gradu-
ated reductions in engine torque and
braking intervention at individually
selected wheels. DSC provides optimal
stability Ð within the limits defined by
the laws of physics.
The system automatically assumes
operational status each time the engine
is started.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 22.
The indicator lamp flashes:
The system is actively regulating drive
torque and braking force.
The indicator lamp does not go out
after the engine is started, or it comes
on during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the
button. You can continue to drive the
vehicle normally, but without DSC.
Please respond to any suspected
defects by referring the problem to your
BMW center.
To deactivate the systemPress the button, the indicator lamp
comes on and stays on.
When DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following rare circumstances, it
may be effective to deactivate the DSC
for a short period of time:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
To maintain vehicle stability,
always drive with the system
switched on when possible.<520de035
Dynamic Stability Control (DSC)

Flat Tire MonitorRepeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after peri-
odic corrections of inflation pressures
to maintain them at the levels stored
during an earlier initialization process. In the event of a flat tireThe red indicator lamp will flash in the
event of a flat tire.
A supplementary gong is also heard.
Carefully reduce speed to less than
50 mph (80 km/h), avoiding any hard
braking or steering maneuvers while
doing so.
For additional details, refer to
page 137.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check tire pressure on a regular
basis and correct it as required.
Refer to page 26.
Do not activate the system when driving
on snow chains or when operating the
vehicle on a closed racing circuit. False
alarms and undetected pressure loss
are both possible under these condi-
tions.
In certain circumstances, there could
be a delayed detection of any loss in
inflation pressure while driving on
snow-covered or slippery road
surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display panel.<
System interferenceThe red indicator lamp in the instrument
cluster will stay on for as long as there
is a malfunction.
The indicator lamp will come on if the
system malfunctions.
Please contact your BMW center for
additional information.

Interior lamps Reading lampsThe interior lamps operate automati-
cally.Switching the interior lamps on
and off manuallyTurn the knob.
If you want the interior lamps to remain
off, keep the knob turned for approx.
3 seconds.
Turn the knob again to turn it back on. Footwell lampsThe footwell lamps operate in the same
way as the interior lamps.520de040
The reading lamps can be switched on
and off using the push button, located
next to each lamp. 520de041
In order to prevent battery
discharge, all of the lamps in the
vehicle are switched off automatically
approx. 15 minutes after the ignition
key has been turned to position 0.<

Heating and ventilation/Air conditionerAir supply
You can select blower speeds
from 1 to 4. The higher the
setting, the greater the
amount of heat and air supply.
In position 0, the blower, heating and
air conditioner are switched off.
Temperature
In order to increase the inte-
rior temperature, turn to the
right. For rapid heating, turn
completely to the right. Then
select an interior temperature that is
comfortable for you.
Air distribution
You can direct the airflow onto
the windows , toward the
upper body and into the
footwell . You can also
make all intermediate settings. The
"6 o'clock" setting is recommended for
normal conditions (refer also to the
illustration and overview on page 72).
Recirculated-air mode
If there are unpleasant odors
in the incoming air, you can
temporarily block the air
supply. The system then recir-
culates the air already within the
vehicle.
If condensation starts to form on
window surfaces during operation
in the recirculated-air mode, switch this
mode off and increase the air supply as
required, or press the button for
"Defrosting windows and removing
condensation".<
Incoming-air mode
Recommended when driving
with the convertible top down.
The degree to which the
passenger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/Incoming-air
mode
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(5 6). This will
help to prevent condensation from
forming on window surfaces.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Air conditioner/Recirculated-air
mode
You may find it useful to acti-
vate both systems to cool the
vehicle more rapidly after it
has been parked with the top
up on a hot day. This setting provides
the coldest possible airflow from the
vent outlets (with temperature selection
switch turned all the way to the left).

Draft-free ventilation You can adjust the air outlets for the
upper body area for optimal personal
comfort:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range.520de043
You can adjust the direction of the
airflow using the levers 2.
Set the air outlets so that the air flows
past you and is not directed straight at
you.MicrofilterThe microfilter removes dust and pollen
from the incoming air. Your BMW
center will change this filter during
routine maintenance. A substantial
reduction in airflow indicates that the
filter needs to be replaced early.520de140
