Parking brake To engageThe lock engages automatically when
you lift the lever, and the indicator lamp
in the instrument panel comes on when
the ignition key is in position 2. Refer to
page 19.To releasePull up slightly on the lever, press the
button and lower the lever.
The parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.520de024
If, in rare circumstances, it should
be necessary to engage the park-
ing brake while the vehicle is in motion,
do not pull hard on the lever. Keep your
thumb pressed against the release but-
ton while carefully pulling the lever up
to apply moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on slopes and inclined sur-
faces, since placing the lever in first
gear or reverse may not provide ade-
quate resistance to rolling.<
To avoid corrosion and one-sided
braking effect, apply the parking brake
lightly from time to time when coasting
to a standstill (at a traffic signal, for in-
stance), provided that it is safe to do so.

The conceptDSC maintains vehicle stability even in
critical driving situations. The system
optimizes vehicle stability during accel-
eration and when starting from a full
stop, as well as optimizing traction. In
addition, the system recognizes unsta-
ble vehicle conditions (understeering or
oversteering, for example) and holds
the vehicle on a sure course by inter-
vening via the engine and by braking
intervention at the individual wheels,
within physically feasible limits.
The system starts up automatically
each time you start the engine.Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 20.
Indicator lamp flashes:
The system is active and governs drive
force and braking force.
If the indicator lamp does not go out
after the engine is started, or if 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 consult your BMW center for re-
pairs.
To deactivate the systemPress the button, and the indicator
lamp comes on and stays on.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following rare circumstances, it
may be a good idea 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

Heating and ventilation/Air conditioningAir supply
You can select blower speeds
from 1 to 4. The higher the set-
ting, the greater the amount of
heat and air supply. In position
0, the blower, heating and air condi-
tioner 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 con-
ditions (refer also to the illustration and
overview on page 70).
Recirculated air mode
If there are unpleasant odors
in the outside air, you can tem-
porarily block the air supply.
The system then recirculates
the air currently within the vehicle.
If the windows fog over when
using recirculated air, turn off the
recirculated air mode and increase the
airflow if necessary, or press the button
for "defrosting and defogging the win-
dows."<
Venting in outside air
Recommended when driving
with the convertible top open.
The degree to which the pas-
senger compartment is
heated depends on temperature selec-
tion and air distribution.
Air conditioner/Venting in outside
air
The air is cooled and dehu-
midified and Ð depending on
the temperature setting Ð
warmed again when the air
conditioner system is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Do not turn on the air conditioner if out-
side air temperature is below approx.
41 7 (5 6). This will help to prevent
the windows from fogging.
If the windows fog over after switching
the air conditioner off, switch it back on.
Air conditioner/Recirculated air
mode
Both systems are operating.
Another advantage is that a
hot vehicle cools down more
quickly with the convertible
top closed. This way, you will get the
lowest possible vented air temperature
(turn the temperature rotary dial all the
way to the left).

air outlets through an infinitely-variable
range.520de043
You can adjust the direction of the air-
flow 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 cen-
ter will change this filter during routine
maintenance. A substantial reduction in
air flow indicates that the filter needs to
be replaced early.520de140

Disc brakes Brake systemDriving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Watch traffic conditions
to ensure that this maneuver does not
endanger other road users. The heat
which is generated by the brake appli-
cations helps to dry the brake pads and
rotors.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique (refer to page 91).
Long or steep mountain descents do
not necessarily lead to reduced braking
efficiency if you drive downhill with the
transmission in a gear requiring minimal
brake applications.
Braking effect on the engine can be
further increased by downshifting, into
first gear, if necessary.If engine braking should prove to be
inadequate, you should still avoid ex-
tended, continuous braking. Instead of
maintaining low to moderate pressure
over an extended period of time, you
should decelerate by applying more
substantial pressure to the brake pedal
(watch for following traffic), releasing
the pedal, and then repeating the appli-
cation (staggered braking). The cooling
phases between active braking inter-
vals prevent the brakes from overheat-
ing and retain full braking capacity.
Do not coast with the clutch de-
pressed, the gear-shift lever in
neutral, or, above all, with the engine
shutt off; otherwise, the engine will pro-
vide no braking effect if the transmis-
sion is in neutral, and there is no brak-
ing or steering power assist if the
engine is not running. Do not allow floor
mats, carpets or any other objects to
protrude into the area around the brake
pedal, the clutch or the accelerator
which could obstruct their freedom of
movement.<
Brake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level is too low in
the reservoir (refer to page 112).
If the brake fluid level is too low
and brake pedal travel has become no-
ticeably longer, there may be a defect
in one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW cen-
ter. Higher brake application pres-
sure may be necessary under these con-
ditions, and brake pedal travel may be
significantly longer. Please remember to
adapt your driving style accordingly.<

Brake system Winter operationBrake pads
The warning lamp for the brake
pads comes on:
The brake pads have reached
their minimum pad thickness. Proceed
to the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has ap-
proved for your specific vehicle model.
BMW cannot evaluate non-approved
brake pads to determine if they are
suited for use, and therefore cannot en-
sure the operating safety of the vehicle
if they are installed.<
Winter is often accompanied by rapid
changes in weather, requiring not only
a different driving style, but also certain
preparations to the vehicle itself to en-
sure that your vehicle operates safely
and trouble-free throughout the winter
months. CoolantBe sure that the coolant mixture con-
tains the year-round ratio of 50:50 water
and antifreeze/corrosion protection.
This mixture provides protection against
freezing down to approx. Ð 34 7
(Ð 37 6). LocksBMW door lock deicer can be used to
free doors if frozen. This deicer also
contains lubricant.
After using the deicer, treatment with
BMW lock cylinder grease is recom-
mended.
Rubber seals and components To prevent the weather-stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.

on the rear wheels with approved winter
tires. Always follow the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
Do not activate the RDW system while
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are possible when driving with snow
chains.
Starting offWhen starting off in deep snow or when
"rocking" the vehicle to free it, it may be
advisable to temporarily deactivate the
DSC system. Refer to page 63.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<
