Luggage compartment lid Electric power windows
Do not drive with the luggage
compartment lid open, since
exhaust fumes could penetrate the inte-
rior of the vehicle. Should it be abso-
lutely necessary to operate the vehicle
with the luggage compartment lid open
(coupe; roadster with closed convert-
ible top):
>Close all windows. On the coupe,
close the sunroof.
>Increase the air supply of the heating
and ventilation system to a high level.
Refer to page 72.<
Opening and closing windowsFrom ignition key position 1 and up:
>Depress the rocker switch until you
feel resistance:
The window continues moving for as
long as you maintain pressure on the
switch.
>Press the rocker switch beyond the
resistance point (one-touch mode):
The window moves automatically.
Press the switch a second time to
stop the window.36mde744
After the ignition has been switched off:
Actuation is still possible for up to
15 minutes in ignition key position 0 or
if the ignition key has been removed, as
long as no doors have been opened.
Because the power windows are
sealed at high pressure to prevent
wind noise when closed, a powerful
motor is required for efficient closing.
When closing the windows, always
ensure that they are not obstructed in
any way. Unsupervised use of these
systems can result in serious personal
injury. Remove the ignition key to deac-
tivate the electric power windows
whenever you leave the vehicle. Never
leave the keys in the vehicle with unsu-
pervised children.
Never place anything that could
obstruct the driver's vision on or next to
the windows.<

Antilock Brake System (ABS)The conceptABS increases active safety by
preventing the wheels from locking
when braking. The reason: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
The system can achieve the shortest
braking distances possible under most
conditions (on straight-aways, in curves
and on various road surfaces.).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>Assured ability to steer and maneuver
on the various road surfaces (asphalt,
concrete, dirt, wet conditions, snow
and ice).
Braking with ABSThe system is operative once the
vehicle exceeds a speed of approx.
6 mph (10 km/h). It is inactive once
again below approx. 4 mph (6 km/h).
Therefore, the wheels could theoreti-
cally tend to lock in the final phase of a
braking action, but this is insignificant in
actual practice.
If you are in a situation which requires
full braking, you will exploit the full
benefits of the ABS system if you apply
maximum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.The ABS closed-loop control circuit
cycles in fractions of a second. The
pulsation at the brake pedal, together
with sounds generated by the hydraulic
control system, indicate to you that the
vehicle is approaching its maximum
braking range. It is a reminder to you
that you must adapt the vehicle's road
speed to existing road conditions.
On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel, deep sand or snow,
for example), braking distances may be
longer than with locked wheels. This
also applies for driving with snow
chains. However, ABS continues to
provide enhanced vehicle stability and
steering response under these condi-
tions.

Antilock Brake System (ABS)Information for your safetyNot even ABS can suspend the laws
of physics. ABS alone cannot prevent
accidents if the brakes are applied
without an adequate, safe distance
between vehicles or if the speed limit
has been exceeded. Nor can it prevent
the hazards of aquaplaning. Responsi-
bility for these types of situations
remains in the hands (and at the feet) of
the driver. You should never allow the
added safety of ABS to lull you into a
false sense of security, or mislead you
into taking increased risks that could
affect your own safety and that of
others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.< Antilock Brake System (ABS)/
Cornering Brake Control (CBC)CBC is an advanced engineering
feature of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.
In the event of a malfunction
The ABS warning lamp comes
on, refer to page 22. The brake
system then reverts to conven-
tional operation as on vehicles
without ABS. However, have the
brake system checked by your
BMW center as soon as possible. To
prevent undetected defects and cumu-
lative faults from adversely affecting the
brake system, refer any problems to
your BMW center at the earliest oppor-
tunity.
If the red warning lamp for the
brake hydraulic system comes
on together with the yellow indi-
cator lamps for ABS and DSC
(refer to page 21), the entire
ABS, CBC and DSC control
system has failed. Continue to
drive cautiously and defensively.
Avoid full brake applications
because the vehicle could become
unstable and go out of control.
Have the system checked by your BMW
center as soon as possible.

Disc brakesDisc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, or in oper-
ating conditions where brake applica-
tions are less frequent, there is an
increased tendency for corrosion of the
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads to clean
the discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
For your own safety: use only
brake pads that BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle in the event of their use.<
Driving notesWhile driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles – watch traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
generated in this braking process helps
dry the brake pads and discs.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
described on page 94.
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible impairment
of the braking effect.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting into first gear, if
necessary. Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead, decelerate
the vehicle with increased pressure on
the brake pedal (watch for following
traffic!), release the pedal and then
repeat the brake application (staggered
braking). This staggered braking tech-
nique allows the brakes to cool in the
intervals between active braking
phases, preventing overheating and
ensuring that full braking capacity
remains available at all times.
Do not drive the vehicle with the
clutch depressed, with the shift
lever in neutral or with the engine shut
off. The engine provides no braking
control when the transmission is in
neutral and there is no power assist for
braking and steering when the engine is
shut off.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<

Winter operationThe onset of winter is often accompa-
nied by rapid changes in weather.
Adaptations in driving style should be
accompanied by preparations on the
vehicle itself to ensure that your vehicle
operation through the winter remains
safe and trouble-free.CoolantEnsure that the coolant contains the
year-round 50 : 50 ratio of water and
antifreeze with corrosion inhibitor.
This mixture provides protection
against freezing down to approx.
– 34 7 (– 37 6). Replace the coolant
every three years.LocksBMW door lock deicer can be used to
free the doors if they are frozen. This
deicer also contains lubricant.
After using deicer, treatment with BMW
lock cylinder grease is recommended.
Rubber seals and components In order to prevent freezing, apply BMW
rubber treatment or silicone spray to
weather-stripping on the doors, hood,
luggage compartment and to convert-
ible top seals.
A full range of car-care products is
available from your BMW center.< Snow chainsMount the BMW snow chains
* only in
pairs on the rear wheels only. Comply
with the manufacturer's safety precau-
tions. Do not exceed a speed limit of
30 mph (50 km/h) when driving with
chains. As an exception in this situa-
tion, we recommend that you deacti-
vate the DSC and RDW when snow
chains are mounted. Refer to page 65
or page 67.
Starting offWhen starting from a full stop or
"rocking" free in deep snow, we recom-
mend that you deactivate the DSC
system. Refer to page 65.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Shift down
into the next lowest gear when
approaching uphill or downhill grades.
Maintain an adequate distance between
yourself and the vehicle ahead.Braking Winter road conditions substantially
reduce the traction available between
the tires and the road surface.
Remember that – in every situation –
braking distances will be significantly
longer as a result of this.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
