How the system functions
You have probably frequently wished that
you could configure individual functions of
your vehicle to reflect your own personal
requirements. In engineering your vehicle,
BMW has incorporated a number of
options for personal adjustment that can be
programmed into your vehicle at your BMW
center.
Vehicle Memory refers to vehicle-oriented
settings and Key Memory refers to person-
oriented settings. You can have up to four
different basic settings adjusted for four
different persons. The only requirement is

Adjustments
32 that each person uses his or her own
remote control key.
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 adjust-
ments accordingly.
Distinguishing between keys
Colored decals were provided with the
keys to help you distinguish between the
different personal remote control keys.
What the system can do
You can learn about the entire array of fea-
tures that Vehicle Memory and Key Mem-
ory offer you at your BMW center. A few
examples follow below:
Examples for Vehicle Memory:
>Various signals as acknowledgement
when locking or unlocking your vehicle:
refer to pages 17,, 18
>Windows are opened automatically,
refer to page 20
>Reminder that the key is still in the igni-
tion switch after the driver's door has
been opened, refer to page 37
>Activation/deactivation of the Follow-
me-home function: refer to page 46
>Activation/deactivation of daytime driv-
ing lamps: refer to page 46
>Sets the units of measure for displaying
time, outside temperature, distance
traveled and fuel consumption in the
instrument cluster, refer to page 50.
Examples for Key Memory:
>Locking of the vehicle when you start
off: refer to page 18
>Automatically adjusts the driver's seat
to the personal programmed settings
when the vehicle is unlocked, refer to
page 29.
You will see this symbol throughout
the Owner's Manual. It is to remind
you at appropriate places of the settings
that are available to you.<
Depending on how the memory func-
tions are configured, the vehicle may
be operated differently from what is
described in the Owner's Manual. Should
you decide to sell your BMW one day,
please remember to have the memory
functions returned to their original factory
settings.<

Transporting children safely
Children on the passenger's
seat
Deactivating/reactivating passenger
airbags
The passenger airbags must be deac-
tivated before using a rear-facing
child-restraint system on the passenger
seat, refer also to page 34 for explanation.
BMW also recommends that the passenger
airbags be deactivated if a child is trans-
ported in a front-facing child-restraint sys-
tem, regardless of the age of the child. If
you transport a child in the passenger seat,
not an infant in a rear-facing seat, who is
properly seated and seat-belted at all
times, the potential benefits of airbags
deploying in an accident generally out-
weigh the risks of the child being injured by
the force of a deploying airbag.
Therefore, you should deactivate the pas-
senger airbags only if you find it difficult to
ensure that the child will remain properly
seated and seat-belted at all times.
Always position the passenger seat as far
back as possible and at the lowest level.
The above warning and recommendations
are compatible with regulations estab-
lished by the National Highway Traffic
Safety Administration, NHTSA, permitting
the deactivation of passenger airbags by
means of an on-off switch for members of
certain at-risk groups.
Specifically, the at-risk groups are:
>Infants in rear-facing infant seats
>Persons with certain medical conditions
>Children aged 12 and under in the pas-
senger seat.
NHTSA provides this information via their
website, www.nhtsa.dot.gov, or via their
Auto Safety Hotline toll-free at
1-800-424-9393 or 366-0123
in Washington, D.C. area.<
The concept
Passenger airbags can be deactivated/
reactivated with the vehicle ignition key.
The key switch is located on the outer pas-
senger's side of the instrument panel.
The passenger airbags can only be deacti-
vated or reactivated with the vehicle stand-
ing still, ignition off and the passenger door
open.
Deactivation
Deactivation of the passenger airbags sys-
tem deactivates the passenger front, knee
and side airbag. The airbags on the driver
side remain active.
Using the vehicle ignition key, turn the key
switch to the OFF position. Note, the pas-
senger airbags will remain deactivated with
the switch in this position.
As soon as the reason for the deacti-
vation of the passenger airbags no
longer exists, you must reactivate these air-
bags so that they can deploy in an accident
within their normal deployment range.<
Reactivating
Using the vehicle ignition key, turn the key
switch to the AUTO position.
All airbags in the vehicle are activated and
will be triggered under appropriate condi-
tions.

Passenger airbags lamp
The system checks that the airbag system
is functioning properly when the ignition
key is turned, and the indicator lamp in the
central console lights up for several sec-
onds.
>The indicator lamp lights up continu-
ously when the passenger airbags are
deactivated
>If the passenger airbags are activated, it
goes out after several seconds.
At all times, occupants should sit
comfortably upright and be properly
restrained, infants and small children in
appropriate child-restraint systems; larger
children and adults using the safety belts.
Please note that the word Airbag imprinted
on the door trim panel indicates the air-
bag's location.<
Seat position for children
This is the correct way a larger child no
longer using a child-restraint system
should sit wearing the safety belt, when the
airbag system is activated.
Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Never install a rear-facing child-
restraint system in the passenger seat
of this vehicle, unless the passenger air-
bags have been turned off and the indicator
lamp in the center console indicates that
the passenger airbags are deactivated. For
a child, not an infant, certain precautions
should be taken. Position the passenger
seat as far back as possible and at the low-
est level. This important precaution is
intended to maximize the distance
between the airbags and the child. Younger
children should be secured in an appropri-
ate forward-facing child-restraint system
that has first been properly secured. Older
children should be tightly secured with a
safety belt, sitting with their back against
the vehicle seat back. Always ensure that
all occupants, of all ages, remain properly
and securely restrained at all times.<
Always follow the manufacturer's
instructions concerning installation
and use; otherwise the system's protective
function could be impaired. After an acci-
dent, have all parts of the affected safety
belt system inspected and/or replaced by
your BMW center.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to children.
Always read and follow the instructions that
come with the system.

0 Steering locked
This is the only position in which the igni-
tion key can be inserted or removed.
After removing the key, turn the steering
wheel slightly to the left or right until the
lock engages.
If the key is not removed, an acoustic signal
sounds when the driver's door is opened.
Vehicles with automatic transmission:
do not move the selector lever from
position P until the engine is running.<
Interlock
In order to turn the key back to position 0 or
to remove it, move the selector level into
position P first.
1 Steering unlocked
You will find that it is often easier to turn the
ignition key from position 0 to 1 if you move
the steering wheel slightly to help disen-
gage the detent.
Individual electrical equipment and acces-
sories are available for use.
2 Ignition switched on
All systems are operational.
3 Engine started
Engine
Do not allow the engine to warm up while
the vehicle is stationary. Instead, begin
driving immediately at a moderate engine
speed.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up 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 electrical devices that
are not in use. Switch the ignition off when
the vehicle is not being driven.
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 poses a safety haz-
ard.
When driving, standing at idle and parking
the vehicle, take care to avoid contact
between the hot exhaust system and flam-
mable materials, e.g. hay, leaves, grass,
etc. Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
Starting the engine
Do not press the accelerator pedal while
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 depressed.<
Do not actuate the starter for too
short a time, but do not actuate it for
more than approx. 20 seconds. Release

with the selector lever in neutral position N,
a warning tone and the flashing gear indi-
cator in the display remind you that the
vehicle is not secured against rolling.
The warning stops after approx. 9 seconds.
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently secure
the vehicle against rolling.<

Parking brake
The parking brake is designed primarily to
prevent the vehicle from rolling when
parked. It operates against the rear wheels.
Indicator lamp
The indicator lamp lights up when
the parking brake is engaged; if you
start driving, an acoustic signal is
heard as well.
The indicator lamp for Canadian
models lights up when the parking
brake is engaged; if you start driv-
ing, an acoustic signal is heard as well.
To engage
The detent engages automatically and the
indicator lamp in the instrument cluster
comes on when the ignition key is in posi-
tion 2.
To release
Pull up slightly on the lever, press the but-
ton and lower the lever.
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
the release button on the parking brake
lever pressed down while pulling up the
lever.
Excessive pressure can lead to overbraking
and loss of traction, fishtailing, at the rear
axle.
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, since shifting into 1st gear or reverse
may not provide adequate resistance to
rolling. Vehicles with automatic transmis-
sion: place the selector lever in
position P.<
To avoid corrosion and one-sided
braking, apply the parking brake
lightly from time to time when coasting to a
standstill – at a traffic signal, for example –
provided that it is safe to do so.<
Manual transmission
6-gear transmission*
When shifting into 5th or 6th gear, it is
important to press the gear shift lever to the
right to avoid accidentally engaging 3rd or
4th gear.
Reverse
Select reverse only when the vehicle is sta-
tionary. Press the gearshift lever to the left
to overcome the resistance.
As you do this, the backup lamps will turn
on automatically when the ignition key is in
position 2.
Do not hold the vehicle in place on
slopes by slipping or riding the clutch.
Use the parking brake instead, otherwise,
the ensuing friction to the clutch plates will
cause a great deal of wear and tear on the
clutch.<
