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 convenient
access
*, the remote control contains a replace-
able 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 below.
In addition, information about service require-
ments is stored in the remote control, refer to
Service data in the remote control, page212.
Integrated key
Press button1 to release the key.
The integrated key fits the following locks:
>Glove compartment, refer to page105
>Driver's door, refer to page31
>Luggage compartment lid, refer to page33
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 convenient access
* is
in use.
Personal Profile settings

keys, refer to page21

Pinch protection system
If the closing force exceeds a specific value as a
window closes, the closing action is interrupted
and the window reopens slightly.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories that might inter-
fere with window movement. Otherwise the
pinch protection system could be impaired.<
Closing without pinch protection
If there is an external danger, or if ice on the win-
dows, etc., prevents you from closing the win-
dows normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there. Pinch protection is limited and
the window reopens slightly if the closing
force exceeds a certain value.
2.Pull the switch again past the resistance
point within approx. 4 seconds and hold it
