The concept
Your BMW is equipped with a full mobile phone
preparation package. After pairing a suitable
mobile phone in the vehicle once, you can oper-
ate the mobile phone via iDrive, with the buttons
on the steering wheel and by voice.
A mobile phone that has been paired once is
automatically detected again with the engine
running or the ignition switched on as soon as
it is in the vehicle interior. The pairing data of up
to four mobile phones can be stored simulta-
neously. If several mobile phones are detected
simultaneously, the respective last mobile
phone paired can be operated via the vehicle.
Using a phone in your vehicle
Using 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
Sports Activity Vehicle Center which mobile
phones snap-in adapters are offered for.
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
Ask your BMW Sports Activity Vehicle 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. Mal-
functions 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 Caring for your
vehicle brochure and in the separate mobile
phone operating instructions.
Operating options
You can operate the mobile phone* using:
>Buttons on steering wheel, refer to page11
>iDrive, refer to page214
>Voice commands, refer to page219
>Programmable memory/direct selection
buttons, refer to page21
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
Placing phone calls with BMW Assist
system*: BMW Assist calls
You can use the BMW Assist system via the
hands-free unit for BMW Assist calls.
When the status information "Communication"
or "BMW Assist" is displayed in "BMW Ser-
vice", only BMW Assist calls are possible.
It may not be possible to establish a telephone
connection using the mobile phone while a con-
nection is being established to BMW Assist
or while a call to BMW Assist is already in
*

Adjusting volume
Turn the knob during a call to select the desired
volume.
This volume for the hands-free system is main-
tained, even if the other audio sources are set to
minimum volume.
You can also adjust the volume with buttons on
the steering wheel, refer to page10.
The setting is stored for the remote control cur-
rently in use.
Operation via iDrive
You can operate the following functions via
iDrive:
>Accepting/refusing a call
>Dialing phone numbers
>Dialing phone numbers from the phone
book
>Dialing stored phone numbers, e.g. from the
list of accepted calls.
>Ending a call
When the ignition and radio readiness are
switched off, e.g. after removing the remote
control from the ignition lock, you can continue
an ongoing call via the hands-free system for no
more than 25 minutes.
Speech quality
If the person you are talking to cannot under-
stand you well, this may be due to excessively
loud background noises. The full mobile phone
preparation package can compensate for these
noises to a certain degree. To optimize the speech quality during a call, we recommend
that you:
>Reduce background noises, e.g. by closing
the windows, reducing the air volume of the
automatic climate control or pointing the
opened front air vents downward
>Reduce volume of hands-free system
Requirements
>The pairing data of the mobile phone are
stored in the vehicle and the mobile phone
is ready to operate.
>The engine is running or the ignition is
switched on.
>The mobile phone is detected by the vehi-
cle.

Changing between mobile
phone and hands-free system
From mobile phone to hands-free
system*
You can continue calls begun outside the Blue-
tooth range of the vehicle via the handsfree sys-
tem when the engine is running or the ignition is
switched on. Depending on your mobile phone,
the system automatically switches over to the
handsfree mode.
For mobile phones that do not automatically
switch over to the handsfree mode:
>Depending on the mobile phone model
used, the conversation can be continued via
the hands-free system if necessary. Act
according to what is shown on the mobile
phone display, refer to the operating
instructions of your mobile phone.
>Press the button above the storage
compartment. Switching over may take
several seconds.
From handsfree system to mobile
phone
When you telephone via the handsfree system,
you can also continue the call via the mobile
phone if necessary, depending on the mobile
phone model. Act according to what is shown
on the mobile phone display, refer to the oper-
ating instructions of your mobile phone.
As an alternative, you can deactivate the Blue-
tooth link.
Depending on your mobile phone model, poor
reception of the wireless communications net-
work can result in the system changing from the
hands-free system to the mobile phone.
Operation by voice*
The concept
You can operate your mobile phone without
having to remove your hands from the steering
wheel. When making your entries, you will be supported by announcements or questions in
many cases.
The same prerequisites as for operation via
iDrive apply, refer to page214.

Voice phone book
Operating by voice command requires a per-
sonal voice phone book.
>With separate drives for audio CDs and nav-
igation DVDs, the entries are automatically
applied from your mobile phone's memory.
>With a single drive, the entries must be
entered by voice and are independent of
your mobile phone's memory. In this case, it
is not possible to use voice command either
to call phone numbers stored in the mobile
phone or to store new numbers. Up to 50
entries can be input. An entry always con-
sists of a name and phone number.

Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
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 increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact tire
*: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect tire pressures, a condition that can not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci-
dent. Do not drive with depressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page92, or reset the Tire Pressure Monitor,
refer to page94.<
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 and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW Sports Activ-
ity Vehicle Center. tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages.
Otherwise tire damage and accidents could
occur.<

Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page239.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
suitable for winter conditions. For the sake of
safety, new tires should be installed.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW Sports Activity Vehicle Center or
tire shop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. If necessary, have the vehicle towed
there. Otherwise, tire damage can be extremely
dangerous to vehicle occupants and other road
users.<
