Airbags1 Front airbags on the driver and
passenger sides
2 Head protection airbags on driver
and passenger side (front and rear
*)
3 Side airbags on driver and passenger
side (front and rear
*)
Protective effectThe front airbags protect the driver and
passenger in the event of head-on colli-
sion where the protection provided by
the safety belt alone would not be
adequate. The head protection airbags
and side airbags help provide protec-
tion in the event of a collision from the
side. Each of the side airbags is
designed to help support the occu-
pant's upper body.39mde084
The side airbags in the rear
passenger area
* of your vehicle
may already have been deactivated,
either at the time of manufacture or by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<
For information on the correct sitting
position, refer to page 40.
The airbags will not be triggered in
the event of a minor accident, a
vehicle rollover or a collision from the
rear.<
Never apply stickers or adhesive-
backed objects of any kind to the
airbag covers. Never attempt to reup-
holster the covers or modify them in any
way. If the airbags deploy in response
to an accident, if you note any signs of
system malfunction, or if you wish to
have any parts of the airbag passenger-
restraint system deactivated, always
contact your BMW center, to whom we
strongly urge you to entrust all testing,
repair and dismantling operations.
Never attempt to modify or tamper with
either the system's electrical wiring or
any of its individual components.
System components include the uphol-
stered surfaces on the steering wheel,
instrument panel, the trim panels on the
front and rear doors (with rear airbags)
and the roof braces as well as the sides
of the headliner above the doors.
Never attempt to remove or dismantle
the steering wheel.
To ensure compliance with official
safety regulations, always entrust
disposal of airbag generators to your
BMW center. Attempts to carry out
service procedures undertaken by
anyone other than specially-trained
professionals can result in system
failure or undesired airbag deployment,
both of which can lead to personal
injury. If the airbags deploy in response
to an accident, always remember to
avoid all contact with system compo-
nents, as they are hot and can cause
burns in the period immediately
following deployment.<

Vehicle Memory, Key Memory How the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own indi-
vidual preferences. In engineering your
vehicle, BMW has incorporated a
number of options for personal adjust-
ment that can be programmed into your
vehicle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle
("Vehicle Memory") or the individual
("Key Memory"). Provided that each
person has a separate remote-control
key, you can have your BMW center
enter two personal adjustments for two
different individuals into the system.463de029
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.
Color-coded decals have been
provided to help you distinguish indi-
vidual keys with different settings.What the system can doYour BMW center can provide you with
details on the capabilities of the Vehicle
Memory and Key Memory systems. A
few examples follow below:
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your
vehicle
>Activates/deactivates the "Follow me
home" function.Examples for Key Memory:
>Locks the vehicle when you start off
>Automatically adjusts the driverÕs
seat, the exterior mirrors and the
steering wheel position to your
personal programmed settings when
you unlock the vehicle
>The automatic climate control
assumes your preset comfort settings
when you unlock the vehicle.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

this position only.
An acoustic warning is sounded when
you fail to remove the ignition key after
opening the driver's door.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages. 390de010
Steering unlocked Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical accessories are

engine. A lockout prevents the engine
from starting with the clutch engaged.
Before starting>Engage the parking brake
>Move the shift lever to the neutral
position
>Step on the clutch pedal.
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 unattended
vehicle with a running engine repre-
sents a potential safety hazard.<

Starting the engine Switching off the engine Starting engineDo not press the accelerator pedal
while starting the engine.
While it is important not to release
the key prematurely, you should
also avoid allowing the starter to
operate continuously for more than
20 seconds at a time. Release the igni-
tion key immediately when the engine
starts.<
Do not warm up the engine by allowing
it to run with the vehicle parked.
Instead, you should drive away immedi-
ately while taking care to avoid high
engine speeds until the engine warms
to its normal operating temperature.
If the engine does not start on the first
attempt (the engine is very hot or cold,
for instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures of roughly +57 (Ð156) or below
and at altitudes of over 3,300 ft
(1,000 m):
>Allow the starter to turn somewhat
longer (approximately 10 seconds)
during your initial starting attempt.
The engine's idle speed is automatically
regulated by the computerized engine-
management system. A brief period at
high idle is normal just after starting; the
idle speed should gradually return to
normal as the engine warms. Should
the engine fail to revert to its normal
idle speed after warming, a problem
may exist: please refer the problem to
your BMW center.
To prevent the battery from discharging,
always switch off any electrical devices
not in use, as well as the ignition when
the vehicle is not being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to catalyst
damage.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious
personal injury and property damage.<
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.
Always engage the parking brake
when parking on hills and inclined
surfaces, as even first gear or reverse
may not provide adequate resistance to
rolling.<

Dynamic Stability Control (DSC)DSC 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 enhancing
traction. In addition, the system recog-
nizes unstable vehicle conditions
(understeering or oversteering, for
example) and holds the vehicle on a
sure course by intervening via the
engine and by braking at the individual
wheels.
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 17.
Indicator lamp flashes:
The system is active and governs drive
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 button.
You can continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate the systemPress the button, the indicator lamp
lights up and remains on continuously.
When DSC is deactivated, you are
driving with conventional power
transfer.
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
>When driving with snow chains.39mde124
To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
Do not use the extra safety margins
furnished by these systems as an
excuse for taking unnecessary risks. DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the pedal.

M Dynamic Driving ControlThe system guarantees that whenever
desired, the system will switch the
Servotronic and the accelerator pedal
response from the sporty-comfortable
mode to a pure performance mode.
This means that steering response
becomes more performance-oriented
and the response of the accelerator
pedal is much more spontaneous
(Performance Recognition). 39mde125
Performance Recognition Press the button with the ignition key in
position 2: the indicator lamp comes
on.
Deactivating Performance Recognition:
press the button again; the indicator
lamp goes out.
The coordinated performance-comfort
mode is activated automatically each
time you start the engine.

Flat Tire MonitorFlat tireIn the event of a flat tire, the message,
"TIRE DEFECT" will appear in the
Check Control. This visual alert will be
accompanied by a gong.
If this occurs, reduce vehicle speed
immediately and stop the vehicle. Avoid
hard braking and overcorrecting at the
steering wheel.
Correct the flat tire using the M Mobility
system (refer to page 128).
The Flat Tire Monitor cannot warn
of sudden serious tire damage
stemming from external causes.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 22.
Do not carry out any kind of system
activation when using snow chains.
Under these kinds of conditions, false
warnings and unidentified losses in
pressure are possible.
In certain circumstances, when driving
on snow-covered or slippery road
surfaces, there may be a delay in identi-
fying any loss in inflation pressure.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display panel.<
System malfunctionsThe message "TIRECONTROL INAC-
TIVE" appears in the Check Control and
remains on until the problem is
corrected.
The same message is displayed if there
is a system malfunction.
Please refer the problem to your BMW
center.

Cargo loading Roof-mounted luggage rack
*
Always position and secure the
load correctly. If you do not, it can
endanger the passengers during
braking or evasive maneuvers.
Never exceed either the approved
gross vehicle weight or the approved
weights for either of the axles (refer to
page 142), as overloading the vehicle
beyond the legally approved levels can
severely compromise its operating
safety.
Do not carry hard or heavy objects
unsecured in the passenger compart-
ment. If you do so, they may be
projected through the air during braking
and evasive maneuvers, thus endan-
gering vehicle occupants.<
A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the cover (arrow), please use
the tool provided with the roof-rack
system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
have a major effect on the vehicle's
handling and steering response.394de757
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the axle weights when
loading the rack. These weights are
listed under "Technical Data" ,
page 142.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Be sure that adequate
clearance is maintained for raising the
sliding/tilt sunroof.
Secure the roof luggage correctly
and securely to prevent it from
shifting or being lost during driving
(danger to following traffic).<
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.

Driving notes Antilock Brake System
Brakes:
Do not rest your foot on the brake
pedal while driving. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear and
possibly even brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing, or hydroplaning, and can lead
to partial or complete loss of traction,
vehicle control and braking effective-
ness.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm). If the water is at that depth,
drive only at walking speed, otherwise
the vehicle can sustain damage to the
engine, the electrical systems and the
transmission.
Rear parcel tray:
Do not place heavy or hard objects on
the rear parcel tray. If you do so, they
could pose a danger to vehicle occu-
pants during a braking or evasive
maneuver.
Clothes hooks:
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. Do not hang any
heavy objects on the hooks, otherwise,
passengers could be injured e.g. during
any hard braking or evasive maneuvers,
or during an accident.<
The conceptThe Antilock Brake System (ABS) keeps
the wheels from locking during braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum pedal 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.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.

108n
Brake systemBrake fluid level If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and the vehicle may exhibit
a slight tendency to pull to one side
when the brakes are applied. Braking
distances may also be longer. Please
remember to adapt your driving style
accordingly.<
Disc brakesLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which
braking is restricted to gentle, low-
pressure applications will all increase
the tendency for corrosion to form on
the rotors; this is often accompanied by
a simultaneous accumulation of
contamination on the brake pads. The
pads must exert a certain minimal level
of pressure against the rotors for the
disc brakes' inherent self-cleaning
effect to remain effective; the pressure
available under the above conditions
may not provide adequate cleansing.
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.
When driving in heavy rain and on wet
roads it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to
ensure that this maneuver does not
pose a hazard to you or to other road
users. The heat generated in this
process helps dry the pads and rotors
to ensure that your brake system will
respond with undiminished efficiency
when you need it.When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine shut off. The
engine provides no braking effect when
the clutch is depressed and there is no
power-assist for braking or 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.<
Brake pads
For your own safety: use only
brake pads that BMW has
approved for your particular 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 if they are installed.<
