How the system functionsYou have probably frequently wished
that you could configure individual
functions of your vehicle to reflect your
own personal requirements. In devel-
oping this vehicle, BMW has "built in" a
few options that, should you so desire,
your BMW center can adjust for you.
There are settings related to the vehicle
("Car Memory") and settings related to
individuals ("Key Memory"). You can
have up to four different basic settings
adjusted for four different persons. The
only requirement is that each person
uses his or her own master key with
remote control.
When your vehicle is unlocked with the
remote control, the vehicle recognizes
the individual user by means of a data
exchange with the key, and makes
adjustments accordingly.
In order for you to distinguish between
different keys, colored decals are
supplied together with the keys.What the system can doYour BMW center can provide you with
details on the possibilities that the Car
Memory and Key Memory systems
offer.
Examples for Car Memory:
>Various signals that can serve as
acknowledgement for locking and
unlocking the vehicle, refer to
pages 32, 33
>Deactivating/activating the "Follow-
Me-Home lamps" function, refer to
page 81
>Activating/deactivating daytime
running lamps
*, refer to page 81
>Set the units of measure to indicate
outside temperature and distance
traveled on the instrument panel,
refer to page 19.

AirbagsSitting correctly with airbags
Comply with the following instruc-
tions for the airbags. If you do not,
the airbags may not be able to provide
their maximum protection, with
resulting risks to personal safety. The
following information pertains to all
occupants:
Even though there is an airbag, wear a
safety belt every time you get in the
vehicle, because airbags supplement
the safety belts as an additional
restraint device.
Assume a sitting posture that is
comfortable and allows the greatest
possible distance between you and the
airbags.
Always hold the steering wheel by the
rim to keep any chance of injury to
hands or arms to an absolute minimum,
should the airbag deploy. Keep the
instructions regarding sitting properly in
your seat on page 45 in mind as well.
No one and nothing is to come between
the airbag and the seat occupant.
Do not use the cover panel above the
front 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 use any child restraint systems
on the passenger side. Children under
12 years of age, who are smaller than
5 feet (150 cm), may ride in the back
only.
If your vehicle 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 direction 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 appro-
priate 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" imprinted on the door
trim panel indicates the airbag's loca-
tion.
Accident research shows that the
safest place for children in an automo-
bile 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 airbag, if so equipped. For
example, a child Ñ even though belted
Ñ 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
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 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

Steering locked The key can be inserted or removed in
this position only.
To lock the steering column after you
have removed the key, turn the steering
wheel until you hear it lock.
If the key is not removed, an acoustic
signal sounds after the driver's door
has been opened.
Steering unlocked Individual electrical accessories are
ready for operation.
You will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock. Ignition switched onAll electrical equipment and accesso-
ries are available for use. 1 Engage the parking brake
2 Put manual-shift gear lever in idling
position
3 Step on the clutch pedal
4 Turn the key to position 3 to start the
engine.
Do not actuate the starter for too short
a time. Do not turn it for more than
approx. 20 seconds. Release the igni-
tion key immediately when the engine
starts.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a potential safety hazard.<
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
begin driving immediately at a
moderate engine speed.<

Starting the engine Switching off engine Parking brake If the engine does not start on the first
attempt (if the engine is very hot or
cold, for instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures,
starting at about +5 7 (Ð15 6) and
at high altitudes over 3,300 ft
(1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from
discharging, always deactivate elec-
trical devices that are not in use. Switch
the ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving. If
you do so, the steering will lock, making
it impossible to steer the vehicle.
When you leave the vehicle, always
remove the ignition key and engage
the steering lock.
Set the parking brake when parking on
steep hills, because under certain
conditions, putting the vehicle into first
gear or reverse may not be enough to
prevent it from rolling away.
The power assist is not available when
the engine is not on. This means that
more effort is required to apply the
brakes.<
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates against the rear
wheels. To engageThe lever engages automatically, the
indicator lamp in the instrument panel
comes on when the ignition key is in
position 2. Refer to page 21.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.

Dynamic Stability Control (DSC) The conceptDSC maintains 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, it also recognizes
unstable driving conditions such as
understeering or oversteering in curves,
and helps the vehicle remin on a steady
course by using the engine and brake
system to intervene at the different
wheels. This, of course, is true only
within physically teasible limits.
The DSC is operational every time you
start the engine. The laws of physics cannot be
repealed, even with DSC. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stability.
For additional details concerning DSC,
refer to the chapter "Advanced tech-
nology" on page 158.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on. Refer to pages 21, 22.
>Indicator lamp flashes: the DSC is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the DSC has been
switched off via the button or there is
a malfunction. You can continue to
drive the vehicle normally, but
without DSC. Please consult your
BMW center for repairs.

Tire Pressure Warning (RDW)Activating/deactivating the
systemThe system is automatically active in
ignition key position 2 and is therefore
always on during driving.
To deactivate the system: tap the
button, the indicator lamp will light up
yellow.
To activate the system: tap the button
again, the indicator lamp goes out.
Deactivate the system while driving
with snow chains, since false warnings
and undetected losses in pressure are
possible under these kinds of condi-
tions.
Flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of tire pressure loss.
In addition, an acoustic signal is
sounded. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.
Fix the flat tire using the M Mobility
system (refer to page 145).
Reset the indicator lamp: the red indi-
cator lamp must be switched off manu-
ally after mounting a new wheel. At this
point, hold the RDW switch down until
the indicator lamp goes out. Reinitialize
the system afterward.
The RDW cannot alert you to
severe and sudden tire damage
caused by external factors.
The RDW will not identify the natural
loss of pressure in all four tires, either.<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 26.
Under certain circumstances, there
may be false warnings or a delayed
detection of pressure losses when
driving on snow-covered or slippery
road surfaces.
A sporty driving style (slip at the wheels
receiving the torque, high lateral accel-
eration) can lead to delayed RDW warn-
ings.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.

Antilock Brake System (ABS)The concept ABS keeps the wheels from locking
while braking, thereby enhancing active
driving safety. 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.
Based on current road conditions, ABS
can brake the vehicle within the
shortest possible distance and with the
greatest possible driving stability (on
straight-aways and curves, asphalt, ice,
wet road surfaces, 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 Ð 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). Whenever the
vehicle's speed drops below approx.
4 mph (6 km/h), the ABS is deactivated.
This means that the wheels can lock in the final phase of a panic stop Ð a factor
of no significance in actual use.
The ABS system works best in situa-
tions requiring maximum pressure on
the pedal ("panic stop"). Do not let up
on the brake pedal even after it starts
pulsating. Since the vehicle maintains
steering responsiveness, you can
nevertheless avoid possible obstacles
with a minimum of steering effort.
The ABS closed-loop control circuit
cycles in fractions of a second. Pulsa-
tion at the brake pedal shows you that
ABS is active, that you are braking
within the ABS' braking range and that
you are thus pushing the limit of the
system. In addition, a pulsation Ð a
result of the control function cycles Ð
indicates to the driver that the 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
surface).
On road surfaces with a loose surface
layer over a firm base, e.g. on gravel or
snow, as well as when driving with
snow chains on, braking distances may
be longer for a locked-wheel condition.
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. The consequences of hitting
the brakes when there is inadequate
distance between vehicles, when the
vehicle is driven at excessive speeds
through curves, or during aquaplaning,
remain the driver's responsibility. You
should never allow the added safety of
ABS to lull you into a false sense of
security, or mislead you into taking 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
design 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.
