Vehicle Memory, Key Memory
How the system functions
You have probably frequently wished that you
could configure individual functions of your
vehicle to reflect your own personal require-
ments. 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 set-
tings and Key Memory refers to person-ori-
ented settings. You can have up to four different
basic settings adjusted for four different per-
sons. The only requirement is 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

Adjustments
32 user by means of a data exchange with the key,
and makes adjustments accordingly.
Colored decals were provided with the keys to
help you distinguish between the different per-
sonal remote control keys.
What the system can do
You can learn about the entire array of features
that Vehicle Memory and Key Memory 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
page17
>Windows are opened automatically, refer to
page20
>Reminder that the key is still in the ignition
switch after the driver's door has been
opened, refer to page37
>Activation/deactivation of the Follow-me-
home function: refer to page56
>Activation/deactivation of daytime driving
lamps: refer to page56
>Sets the units of measure for displaying
time, outside temperature, distance trav-
eled and fuel consumption in the instru-
ment cluster, refer to page48.
Examples for Key Memory:
>Locking of the vehicle when you start off:
refer to page18
>Automatically adjusts the driver's seat to
the personal programmed settings when
the vehicle is unlocked, refer to page29.
You will see this symbol throughout the
Owner's Manual. It is to remind you at
appropriate places of the settings that are avail-
able to you.<
Depending on how the memory functions
are configured, the vehicle may be oper-
ated 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 fac-
tory settings.<

Transporting children safely
Children on the passenger's
seat
Deactivating/reactivating passenger
airbags
The passenger airbags must be deacti-
vated before using a rear-facing child-
restraint system on the passenger seat, refer
also to page34 for explanation.
BMW also recommends that the passenger air-
bags be deactivated if a child is transported in a
front-facing child-restraint system, regardless
of the age of the child. If you transport a child in
the passenger seat, not an infant in a rear-fac-
ing seat, who is properly seated and seat-belted
at all times, the potential benefits of airbags
deploying in an accident generally outweigh the
risks of the child being injured by the force of a
deploying airbag.
Therefore, you should deactivate the passen-
ger 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 established by the
National Highway Traffic Safety Administration,
NHTSA, permitting the deactivation of passen-
ger 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 passen-
ger seat.
NHTSA provides this information via their web-
site, 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/reacti-
vated with the vehicle ignition key. The key
switch is located on the outer passenger's side
of the instrument panel.
The passenger airbags can only be deactivated
or reactivated with the vehicle standing still,
ignition off and the passenger door open.
Deactivation
Deactivation of the passenger airbags system
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 passenger
airbags will remain deactivated with the switch
in this position.
As soon as the reason for the deactivation
of the passenger airbags no longer exists,
you must reactivate these airbags 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 ON position.
All airbags in the vehicle are activated and will
be triggered under appropriate conditions.

Passenger airbags lamp
The center console contains one of the indica-
tor lamps shown in the illustration.
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 seconds.
>The indicator lamp lights up continuously
when the passenger airbags are deacti-
vated
>If the passenger airbags are activated, it
goes out after several seconds
The passenger airbags are deactivated
when the key switch is in the ON position
and the passenger seat is unoccupied. The
indicator lamp is not lit.<
At all times, occupants should sit com-
fortably upright and be properly
restrained: infants and small children in appro-
priate 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 airbag's location.<
Seating position for children
This is the correct way a larger child no longer
using a child-restraint system should sit wear-ing 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 vehi-
cle, unless the passenger airbags 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, cer-
tain precautions should be taken. Position the
passenger seat as far back as possible and at
the lowest level. This important precaution is
intended to maximize the distance between the
airbags and the child. Younger children should
be secured in an appropriate forward-facing
child-restraint system that has first been prop-
erly 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 instruc-
tions concerning installation and use;
otherwise the system's protective function
could be impaired. After an accident, have all
parts of the affected safety belt system
inspected and/or replaced by your BMW cen-
ter.<
Commercially-available child-restraint systems
are designed to be secured with a lap belt or
with the lap belt portion of a combination 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.

Ignition lock
0 Steering locked
This is the only position in which the ignition 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.
Interlock
Vehicles with automatic transmission:
In order to turn the key back to position0 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 position0 to 1 if you move the
steering wheel slightly to help disengage the
detent.
Individual electrical equipment and accessories
are available for use.
2 Ignition switched on
All systems are operational.
3 Starting engine
Engine
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 leave the engine running in
enclosed spaces. Otherwise, inhaling the
hazardous exhaust gases could lead to uncon-
sciousness and death. The exhaust gases con-
tain carbon monoxide, an odorless and color-
less, but highly toxic gas.
Do not leave the vehicle unattended with the
engine running. An unattended vehicle with a
running engine poses a safety hazard.
Before you leave the vehicle with the engine
running, place the engine in idle first or engage
the P position and apply the parking brake. If
you fail to do this, the vehicle could move.<
Starting the engine
Do not press the accelerator pedal while start-
ing the engine.
Do not let the engine warm up in idling position.
Instead, begin to drive at moderate engine
speeds.
Vehicles with manual transmission:
Step on the clutch when starting the vehi-
cle. A lockout prevents the engine from starting
if the clutch is not depressed.<
Do not end the starting procedure too early, but
do not continue it for more than 20 seconds.
Release the ignition key immediately when the
engine starts.
If the engine fails to start on the first attempt,
e.g. if it is very hot or cold:
Press the accelerator pedal halfway down.
Cold starts at very low temperatures, below
approx. +57/–156, and at high altitudes,
above 3,300 ft/1,000 m:
