Airbags
For your own safety, please ob-
serve the following precautions
concerning airbags, as otherwise their
protective function may be impaired
and your personal safety endangered.
The following information pertains to all
occupants:
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 this case, the safety belt offers the
best protection.
Airbags are located under the cover
panels in the steering wheel, in the in-
strument panel, in the side trim panels
in the front and rear
*, in the roof panels,
and in the sides of the inside roof lining.
Select a seat position that is comfort-
able and allows the greatest possible
distance from each of the applicable
airbags. Hold the steering wheel at the
rim (hands at the "9 o'clock and
3 o'clock" positions) in order to avoid
injuries to the hands or arms if the air-
bag is triggered.
Never allow any objects to obstruct the
area between the airbag and an occu-
pant.
Do not use the cover panel above the
front passenger airbag as a storage
area.
Never tape the airbag cover panels,
cover them over or alter them in any
other way.
Never install a rear-facing child restraint
device on the front passenger seat.
Children under 13 years of age and
children who are smaller than 5 feet
(150 cm), should only travel in the rear
seat.
If your vehicle is equipped with side air-
bags in the rear, be sure that child seats
are installed correctly and with the
greatest possible distance from the side
trim panels. Do not allow children to
lean out of the child's seat in the direc-
tion of the side trim panels. Otherwise,
serious injuries could occur if the airbag
is triggered.
At all times, occupants should sit up-
right and be properly restrained (infants
and small children in appropriate child
restraint systems; larger children 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 injury.
Please note that the word "Airbag" im-
printed on the door trim panel indicates
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
sitting in the rear seat and not properly
restrained may place his or her head on
or near the side 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
difficult for a driver to ensure that chil-
dren in the rear seat will remain prop-
erly positioned at all times and not
place their heads on or near the side
airbag. Therefore, we recommend that
the rear seat side airbags, if provided,
be deactivated if you plan to transport
children in the rear seat.
The rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW cen-
ter. Labels in the rear door opening
should indicate the status of your rear
seat side airbags. If you are uncertain of
their status, or wish to have the airbags
activated or deactivated, please contact
your BMW center.<

0 Steering lock engaged The key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
you hear the lock engage.
If the key is not removed, an acoustic
signal chimes after the driver's door has
been opened.
Vehicles with automatic
transmission:
Move the selector lever from position P
only after the engine is running (ignition
key in position 2).
In order to turn the key back to position 0
or to remove it, move the selector lever
into position P first (Interlock).<462de195
1 Steering lock disengaged Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical devices are ready
for operation.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engine
Vehicles with manual
transmission:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not de-
pressed.c
Before starting>Engage parking brake
>Ensure that the transmission selector
is in "Neutral" (or "Park" if vehicle is
equipped with automatic transmis-
sion)
>Manual transmission: Depress the
clutch pedal
>Automatic transmission: Depress the
footbrake.
Never allow the engine to run with
the vehicle standing in an en-
closed area. The exhaust gases contain
carbon monoxide, an odorless and col-
orless, but highly toxic gas. Breathing
the exhaust gases poses an extreme
health risk, and can lead to uncon-
sciousness and death.
Do not leave the car unattended with
the engine running. An unattended ve-
hicle with a running engine represents a
potential safety hazard.<
>Start the engine. Do not press the
accelerator pedal.

Parking brake To engageThe lock engages automatically when
you lift the lever, and the indicator lamp
in the instrument cluster will light up in
ignition key position 2. See page 21.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked, and operates against the rear
wheels.460de024
If, in exceptional circumstances, it
should be necessary to engage
the parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling up the lever to apply mod-
erate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear.
The brake lamps do not come on when
the parking brake is engaged.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces, as placing the lever in 1st gear or
reverse may not provide adequate re-
sistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park".<
To avoid corrosion, apply the parking
brake lightly from time to time when
coasting to a standstill (at a traffic sig-
nal, for instance), provided that it is safe
to do so.

Automatic transmission with Steptronic
*
You have the option of driving a normal
automatic transmission or switching to
manual.
Whenever you shift the selector lever
out of position D toward the left and
into the M/S gate, the automatic trans-
mission's sports-emphasized shift pro-
gram activates. As soon as you even
begin to move the selector lever in the
direction "+" or "–", Steptronic shifts the
gear and manual operation becomes
active. Whenever you want to use auto-
matic again, just shift the selector lever
toward the right to position D.
The Steptronic automatic transmission
is equipped with ATC (Adaptive Trans-
mission Control). ATC reacts with preci-
sion to your individual driving style and
the current driving conditions. This is
the reason why various shift programs
are used.
For details concerning ATC, please
refer to the chapter "Advanced Tech-
nology" on page 160.
Selector lever positions
P R N D M/S + –
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or
N ("Neutral").Range selectionA lock prevents inadvertent shifts into
some selector lever positions. To re-
lease the shift-lock mechanism, press
the button on the front of the shift knob
(arrow).462de209
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in or-
der to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
Before leaving the vehicle with the
engine running, shift the selector
lever to the "Park" or "Neutral" position
and apply the parking brake. The vehi-
cle will move if this is not done. Do not
leave the car unattended with the en-
gine running. An unattended vehicle
with a running engine represents a po-
tential safety hazard.<

Tire Pressure Control (RDC)
*
The conceptThe RDC monitors the tire pressures at
all four wheels, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the RDC to "learn" the cor-
rect tire inflation pressure, first check
the tire inflation pressure in all tires.
Then compare these pressures with the
tire inflation pressure chart (page 28)
and adjust if necessary. Then activate
the system.
This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not nor-
mal.
Activate the system1 Turn ignition key to position 2
2 Press the switch long enough for the
indicator lamp in the instrument clus-
ter to light up yellow for a few seconds
3 After a few minutes of driving, the
RDC sets the current inflation pres-
sure in the tires as the target value to
be monitored.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.462de228
Loss of tire pressureIf the inflation pressure has dropped too
much over a period of time (which is
normal for any tire), the indicator lamp
will come on with a yellow lamp.
This alerts you to have the tires inflated
to the specified pressures as soon as
possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.
Then activate the system once again.<

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, there is an
acoustical warning signal.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a save
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire
* is
provided for temporary use only in
the case of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire
* that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will also be monitored once the
tires have been mounted and the sys-
tem activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your authorized BMW center has been
trained to work with the RDC system
and is equipped with the necessary
special tools.<
System interferenceThe RDC can be subjected to interfer-
ence locally by outside equipment or
devices which use the same radio fre-
quency.
The indicator lamp will come on with
a yellow lamp during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your authorized BMW
center for additional information.

Antilock Brake System (ABS)The concept ABS enhances active safety by helping
to prevent the wheels from locking dur-
ing brake applications. 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 and in
curves, on asphalt, ice, wet road sur-
faces, etc.).
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, snow, ice).
Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). Below approx. 3 mph
(6 km/h), it is once again deactivated.
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 re-
sponsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal indicates
to the driver that ABS is active, that is,
that the vehicle is within its maximum
braking range. In addition, a pulsation –
a result of the control function cycles –
indicates to the driver that vehicle
speed should be reduced to adapt to
road surface conditions when there is
reduced traction and grip between tires
and road surface (slippery road sur-
face).
In driving conditions where there is a
loose upper surface together with a
subsurface that provides good traction (on gravel or snow, for instance), or with
snow chains, the braking distance may
also be longer than when the wheels
are locked. However, ABS continues to
provide enhanced vehicle stability and
steering response under these condi-
tions.
Information for your safetyNot even ABS can suspend the laws
of physics. ABS cannot prevent the
consequences of brake applications
with inadequate clearances for safety
between vehicles, when exceeding the
speed limit in curves, or the risks in-
volved when aquaplaning occurs. Re-
sponsibility 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 op-
erating conditions where brakes appli-
cations are less frequent, there is an in-
creased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs be-
cause 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: Only use
brake linings that BMW has re-
leased for your particular vehicle model.
BMW cannot vouch for driving safety or
the suitability of brake linings other than
those they have released.<
Driving notesWhile driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brake pedal every few
miles (kilometers). Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat that is generated by the brake ap-
plications helps to dry the brake pads
and rotors.
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 110.
Long or steep mountain descents do
not necessarily lead to reduced braking
efficiency if you drive downhill with the
transmission in a gear that allows mini-
mal brake applications (or, with an auto-
matic transmission, in an appropriate
lower range).
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).Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate the vehicle by applying more
substantial force on the pedal (watch
for following traffic!) and then pausing
before repeating the application. This
staggered braking technique allows the
brakes to cool in the intervals between
active braking phases, preventing over-
heating and ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch de-
pressed or with the transmission
or selector lever in neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch pedal is depressed or the trans-
mission is in neutral, and there is no
power-assist for brakes and steering
when the engine is not running.
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.<
