Anti-trapping mechanism
If the closing force rises beyond a predefined
threshold during closing, the system will imme-
diately stop moving the window prior to lower-
ing it slightly.
Despite the anti-trapping mechanism,
inspect the window's travel path prior to
closing it, as the safety system might fail to
detect certain kinds of obstructions, such as
thin objects, and the window would continue
closing.

The concept
Your BMW is equipped with a full mobile phone
preparation package. After logging on a suitable
mobile phone on the vehicle once, you can
operate the mobile phone via iDrive, with the
buttons on the steering wheel and by voice.
A mobile phone that has been logged on once is
automatically detected again with the engine
running or the ignition switched on as soon as
it is in the vehicle interior. The logon data of up
to four mobile phones can be stored simulta-
neously. If several mobile phones are detected
simultaneously, the respective last mobile
phone logged on can be operated via the vehi-
cle.
Using a phone in your vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a mobile phone
cradle, enables the battery to be charged and
the mobile phone to be connected to the exter-
nal antenna of your vehicle. This ensures
improved network reception and a consistent
voice reproduction quality. Ask your BMW cen-
ter which mobile phones snap-in adapters are
offered for.
BMW discourages the use of mobile
phones or other mobile communications
devices inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate owner's manual for a detailed
description of safety precautions and informa-
tion, we request that you direct your particular
attention to the following:
Only make entries when the traffic situa-
tion allows you to do so. Do not hold the
mobile phone in your hand while you are driving;
use the hands-free system instead. If you do
not observe this precaution, your being dis-
tracted can endanger vehicle occupants and
other road users.<
Suitable mobile phones
Ask your BMW center which mobile phones
with a Bluetooth interface are supported by the
mobile phone preparation package or which
mobile phones snap-in adapters are available
for. These mobile phones support the functions
described in this Owner's Manual with a certain
software version. Malfunctions can occur with
other mobile phones.
Care instructions
You can find what you need to know about car-
ing for your mobile phone in the separate Caring
for your vehicle brochure and in the mobile
phone owner's manual.
Operating options
You can operate the mobile phone* using:
>The steering wheel, refer to page11
>iDrive, refer to page16
>Voice commands, refer to page174
