Airbags
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.<
All vehicle occupants should
always sit upright 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: 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 location.
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 side airbag, if installed. For
example, a child Ð even though belted Ð
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 do 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 chil-
dren 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
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.<
Even when all these guidelines are
followed, there is still a small residual
risk of injuries to the face, hands and
arms occurring in isolated instances.
The ignition and inflation noise may
provoke a mild temporary hearing loss
in extremely sensitive individuals.
Airbag warning information is also
provided on the sun visors.

Vehicle Memory, Key MemoryThe system then relies on a bilateral
data exchange to identify the individual
user and dial in the selected settings
whenever the remote control unit is
used to disengage the door locks.
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 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

>Be sure that the transmission is in
"Neutral" (or "Park" if the vehicle is
equipped with an automatic trans-
mission)
>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.
Never leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<

button and lower the lever.390de714
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
moderate 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 applied.

Air conditioningTemperature
The numbers in the display
panel are reference figures for
general orientation. We
recommend a setting of 70 7
(22 6) for a congenial in-car climate.
When you start the vehicle, this system
adjusts the air to the selected tempera-
ture as quickly as possible, and then
maintains that temperature constantly.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are also available. In
the setting, there is a low flow of air
onto the windows to keep them free of
condensation.
Air supply
You can control the emerging
air's flow rate through an infi-
nitely-variable range. The
heating and ventilation
become more and more effective as the
air supply settings are increased. In the
"0" setting, the blower and climate
control are switched off and the outside
air supply is blocked.
Rear window defroster
The indicator lamp comes
on to indicate that the rear
window defroster is in operation. The
rear window defroster switches off
automatically.
Cooling
The air conditioning cools
and dehumidifies the
incoming air before reheating it to the
selected temperature. Depending on
the weather, the windshield may fog
over briefly when the engine is started.
You can reduce condensation forming
on the windows by switching on the air
conditioning.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to
unpleasant odors in the
surrounding environment by using this
mode to temporarily suspend the flow
of outside air into the vehicle's interior.
The system then recirculates the air
currently within the vehicle.
If your vehicle is equipped with a multi-
function steering wheel
featuring a
recirculated-air button then you can
also select the recirculated-air mode
from this location (refer to page 22).
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.<

Maximum cooling
With the engine running
this program provides
maximum cooling at outside tempera-
tures above approximately 41 7 (5 6).
60 7 (16 6) appears in the tempera-
ture display 9, and the system reverts to
the recirculated-air mode while simulta-
neously providing maximum airflow
through the vent outlets only. That is
why you need to keep these open if you
select this program.
Automatic recirculated-air
control (AUC)
You can respond to
unpleasant external odors
by temporarily stopping the flow of
outside air. The system then recircu-
lates the air currently within the vehicle.
Press the button repeatedly to run
through the following control sequence:
>Indicator lamps off: outside airflow
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air
currently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right-hand indicator lamp on: the
flow of external air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.
If you have a multifunction steering
wheel with the recirculated-air button
(refer to page 22), you can also use it to
switch between "Off" and the recircu-
lated-air mode or AUC and the recircu-
lated-air mode.
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.< Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.

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.
Do not exceed the approved gross
vehicle weight or the permissible axle
weights (refer to page 171). If you do,
the operating safety of the vehicle is no
longer ensured and you are in violation
of the law.
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
exercise a major effect on the vehicle's
handling and steering response.394de757
You should therefore always remember
not to exceed the approved roof
weight, the approved gross vehicle
weight or the axle weights when
loading the rack. You will find the spec-
ifications under "Technical data" on
page 171.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Ensure that adequate room
remains for the tilt sunroof to extend
upward and that no objects protrude
into the tailgate's travel range on the
sport wagon.
Always ensure that roof-mounted
loads are tightly secured, as loose
loads can shift or even fly off the roof,
posing a serious hazard for following
traffic.<
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.

Driving notes Antilock Brake System
Brakes:
Do not drive with your foot resting
on the brake pedal. 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. It is character-
ized by a partial or complete loss of
contact between the tires and the road
surface. The ultimate results are loss of
steering and braking control.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than
1 ft (30 cm), and even then, 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 cargo area cover. These objects
could endanger vehicle occupants
during heavy brake applications or
evasive maneuvers.
Clothes hooks:
Hang items of clothing from the hooks
so that they will not obstruct the driver's
vision. Do not hang heavy objects on
the hooks. If you do so, they could
cause personal injury during braking or
evasive maneuvers.<
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.

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 transmission
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 movement.<
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.<
