AirbagsSitting correctly with airbags
For your safety, comply with the
following instructions for the air-
bags. If you do not, the airbags may not
be able to provide their maximum pro-
tection. All passengers in the vehicle
should be aware of and comply with
this information:
The airbags are supplemental restraint
devices designed to provide extra pro-
tection; they are not a substitute for
safety belts. Wear your safety belt at all
times. The airbags will not be triggered
in the event of a minor accident, a vehi-
cle roll-over, or collisions from the rear.
In these instances, the safety belt pro-
vides optimal protection.
Airbags are located under cover panels
in the steering wheel, in the dashboard
and in the side trim panels in the front.
Adjust your seat to a position that pro-
vides maximum distance between you
and the steering wheel, the instrument
panel and the door while still allowing
comfortable and safe access to all
vehicle controls.
To avoid sustaining hand and arm inju-
ries, always grasp the steering wheel
on the rim with the hands at the 9 and
3 o'clock positions. Do not place your
hands on the center pad.
Never allow any objects to obstruct the
area between the airbag and an occu-
pant.
Do not use the cover panel above the
passenger-side airbag as a storage
area.
Do not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
Do not install a rear-facing child re-
straint system in the front passenger
seat of this car.
Children under 13 years of age and
children less than 5 feet (150 cm) tall
should ride only in the rear seat.
Infants or small children should never
be held on the lap of a passenger.
If your car is equipped with side airbags
in the rear passenger area, be sure that
child restraints are mounted correctly
and provided with the greatest-possible
distance between the airbags in the
side trim panels. Do not allow children
to lean out of the child's seat in the di-
rection of the side trim panels. If they
do so, serious injuries can occur if the
airbag is triggered. upright and be properly restrained
(infants and small children in appropri-
ate child restraint systems; larger chil-
dren and adults using the safety belts).
Never let an occupant's head rest near
or on a side airbag because the inflating
airbag could cause a serious or fatal in-
jury. Please note that the word "Airbag"
imprinted on the door trim panel indi-
cates the airbag's location.
Accident research shows that the saf-
est place for children in an automobile
is in the rear seat. However, a child sit-
ting in the rear seat and not properly re-
strained may place his or her head on
or near the airbag, if so equipped. For
example, a child — even though belted
— may fall asleep with his or her head
against the side airbag. It may be diffi-
cult for a driver to ensure that children
in the rear seat will remain properly po-
sitioned at all times and not place their
heads on or near the side airbag.
Therefore, we recommend that the rear
seat side airbags, if so equipped, be
deactivated if children will travel in the
rear seat.
The rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW
center. Labels in the rear door opening

starting the vehicle. A lockout prevents
the engine from starting if the clutch is
not depressed.<
>Engage the parking brake
>Ensure that the transmission selector
is in "Neutral" ("Park" or "Neutral" if
the vehicle is equipped with auto-
matic transmission
*)
>Step on the clutch pedal when tem-
peratures are low
>Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but do not turn it for
more than approx. 20 seconds. Release
the ignition key immediately when the
engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle re-
mains stationary. Instead, drive off im-
mediately at a moderate engine
speed.<
Do not run the engine in enclosed
areas. The exhaust gases contain
carbon monoxide, an odorless, color-
less, yet highly toxic gas. Breathing the
exhaust gases poses an extreme health
risk, and can lead to unconsciousness
and death.
Never leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<

Dynamic Stability Control (DSC) The conceptDSC helps maintain vehicle stability,
even in critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions (un-
dersteering or oversteering, for exam-
ple) and helps hold the vehicle on a
sure course by intervening via the
engine and by braking intervention at
the individual wheels.
The system activates automatically
each time you start the engine.46cus012
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is active and governs drive
force and braking force.
If the indicator lamp fails to 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 but-
ton. You can continue to drive the vehi-
cle normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate the systemPress the button, the indicator lamp
comes on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 118.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. For this
reason, do not take risks by using the
additional safety margin provided by
the system as an excuse.<

Antilock Brake System (ABS)The concept ABS enhances active driving safety
by helping to prevent the wheels from
locking while braking. This is because
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.
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help maintain steering control and
maneuverability – on all types of road
surfaces (asphalt, concrete, mud, wet
road surfaces, snow, ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight aways and in
curves, on asphalt, ice, wet road sur-
faces, etc.).
Braking with ABSThe system is operative once the vehi-
cle exceeds a speed of approx. 6 mph
(10 km/h). It is deactivated once again
below approx. 4 mph (6 km/h). This
means that the wheels can lock in the
final phase of a panic stop – a factor of
no significance in actual use.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a mini-
mum of steering effort.
The ABS closed-loop control circuit
cycles in fractions of a second. A pulsa-
tion at the brake pedal, together with
the sounds associated with the hydrau-
lic controls, tells you that the brake sys-
tem is within its maximum limit range,
and reminds you that you should adapt
road speed to the road conditions.
On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel or snow, for exam-
ple), or when snow chains are mounted,
braking distances may be longer than
with locked wheels. However, ABS continues to provide
enhanced vehicle stability and steering
response under these conditions.
Information for your safetyNot even ABS can suspend the laws of
physics. ABS cannot prevent the conse-
quences of brake applications with inad-
equate clearances for safety between
vehicles, when exceeding the speed
limit in curves, or the risks involved
when aquaplaning occurs. Responsibil-
ity 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.<

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, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that
must be exerted by the pads to clean
the rotors by brake applications is
not reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads that BMW has ap-
proved for your particular vehicle
model. BMW cannot evaluate non-ap-
proved brake pads to determine if they
are suited for use, and therefore cannot
ensure the operating safety of the vehi-
cle if they are installed.<
Driving notesWhen driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles or kilometers. Watch traffic condi-
tions to ensure that this maneuver does
not endanger other drivers. 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 continue to rotate, 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 described on
page 119.
Extended or steep mountain descents
do not necessarily lead to reduced
braking efficiency if you drive downhill
with the transmission in a gear that
allows minimal brake applications (or,
with automatic transmission
*, in an
appropriate lower gear).
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear or plac-
ing the selector lever in position 1.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, thus ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch de-
pressed or with the shift lever or
selector lever in "Neutral". Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in "Neutral", and there is no power
assist for braking or steering when 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.<

Winter operationBrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
Keep this in mind, because the braking
distance increases substantially.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock,
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking. Then increase the
pressure, reduce the pressure when the
wheels lock, reapply pressure, etc.
This staggered braking procedure will
reduce stopping distances while help-
ing you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces that pro-
vide only poor or uneven traction.<
Skid control Depress the clutch and release the ac-
celerator pedal, or place the selector
lever of the automatic transmission into
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage first or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
Park. On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic
is not endangered.
The brake lamps do not come
on when the parking brake
is applied.<
