The concept
Your BMW is equipped with a full preparation
package mobile phone. After pairing a suitable
mobile phone with the vehicle once, you can
operate the mobile phone via the iDrive, the
buttons on the steering wheel or using voice
commands
*.
Once a mobile phone has been paired with your
vehicle, it is automatically recognized as soon
as it is inside the vehicle while the engine is run-
ning or the ignition is switched on. You can
store the pairing data for up to four mobile
phones simultaneously. If several mobile
phones are detected at the same time, the
mobile phone last paired can be operated via
the vehicle.
Using the telephone inside
the vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a holder for
mobile phones, allows you to charge the mobile
phone's battery and connect the mobile phone
to your vehicle's outside antenna. This ensures
better network reception and consistent repro-
duction quality. Please contact your
BMW center to find out for which mobile
phones there are snap-in adapters available.
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 operating instructions for a
detailed description of safety precautions and
information, 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
Please ask your BMW center which mobile
phones with Bluetooth interface are supported
by the mobile phone preparation package and
which mobile phones are compatible with the
snap-in adapter. By virtue of their particular
software versions, these mobile phones sup-
port the functions described in this Owner's
Manual. Malfunctions may occur with other
mobile phones.
Operating options
You can operate the mobile phone using:
>Buttons on the steering wheel, refer to
page10
>iDrive, refer to page16
>Voice commands

Avoid operating a mobile phone recognized by
the vehicle via the mobile phone's keypad; oth-
erwise, malfunctions may result.
Start-up

Switching between mobile
phone and hands-free system
From mobile phone to hands-free
system*
You can continue ongoing calls outside of the
vehicle's Bluetooth range via the hands-free
system as long as the engine is running or the
ignition is switched on. Depending on your
mobile phone, the system automatically
switches to hands-free mode.
With mobile phones that do not automatically
switch to hands-free mode:
Depending on the type of mobile phone you are
using, it may be possible to continue the con-
versation via the hands-free system. Refer to
the display on your mobile phone and/or your
mobile phone's operating instructions.
From hands-free system to mobile
phone
If you are making a call via the hands-free sys-
tem, it may be possible to continue the call via
the mobile phone, depending on your mobile
phone model. Refer to the display on your
mobile phone and/or your mobile phone's oper-
ating instructions.
Alternatively, you can deactivate the Bluetooth
link, refer to page172.
Depending on the type of mobile phone you are
using, it may occur that calls are switched from
the hands-free system to the mobile phone if
reception of the wireless network is poor.

Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
run-flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to
page85, or reinitialize the Flat Tire Monitor,
refer to page83.<
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100mph or 160km/h.
These tire inflation pressures can also be found
on the driver's side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise,
tire damage and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT … 1010 means that the
tire was manufactured in week 10 of 2010.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement, as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g.
