Remote control
Each remote control contains a rechargeable
battery that is automatically recharged when it
is in the ignition lock while the car is being
driven. Use each remote control at least twice a
year for longer road trips in order to maintain the
batteries' charge status. In cars with Comfort
Access
*, the remote control contains a
replaceable battery, refer to page36.
The settings called up and implemented when
the car is unlocked depend on which remote
control is used to unlock the car, refer to Per-
sonal Profile, next column.
In addition, information about service require-
ments is stored in the remote control, refer to
Service data in the remote control, page206.
Integrated key
Press button1 to release the key.
The integrated key fits the following locks:
>Glove compartment, refer to page103
>Driver's door, refer to page31
New remote controls
Your BMW center can supply new remote con-
trols with integrated keys as additional units or
as replacements in the event of loss.
Personal Profile
The concept
You can set many of your BMW's functions to
suit your personal needs and preferences.
Without any action on your part, Personal Pro-
file ensures that most of these settings are
stored for the remote control currently in use.
When you unlock the car, the remote control
used for the purpose is recognized and the set-
tings stored for it are called up and imple-
mented.
This means that your personal settings will be
activated for you, even if in the meantime your
car was used by someone else with another
remote control and the corresponding settings.
The individual settings are stored for a maxi-
mum of four remote controls. They are stored
for two remote controls if Comfort Access
* is
in use.
Personal Profile settings
For more information on specific settings, refer
to the specified pages.
>Assignment of programmable memory
keys, refer to page21
>Response of the central locking system
when the car is unlocked, refer to page29
>Automatic locking of the vehicle, refer
to page32
>Automatic call-up
* of the driver's seat posi-
tion, refer to page43
>Triple turn signal activation, refer
