Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system TPMS that illumi-
nates a low tire pressure indicator lamp when
one or more of your tires are significantly
under-inflated. Accordingly, when the low tire
pressure indicator lamp comes on, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure indicator
lamp.
The TPMS malfunction indicator is combined
with the low tire pressure indicator lamp. When
the system detects a malfunction, the indicator
lamp will flash for approximately one minute and
then remain continuously lit. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire pres-
sure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction indicator lamp after replac-
ing one or more tires or wheels on your vehicle
to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to func-
tion properly.Brake force display

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
*
4Knee airbags
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please follow the adjustment instructions on
page43.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head. The knee air-
bags help protect the legs against impact
against the cockpit.
The airbags are deliberately not triggered in
every impact situation, e.g. less severe acci-
dents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument panel, the
doors and the roof pillars along with the sides of the headliner. Do not attempt to remove or dis-
mantle the steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns. In the event
of malfunctions, deactivation, or triggering of
the airbag restraint system, have the testing,
repair, removal, and disposal of airbag genera-
tors executed only by a BMW center or a work-
shop that works according to BMW repair
procedures with correspondingly trained per-
sonnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Warnings and information about the airbags is
also provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The system
appropriately activates or deactivates the front,
knee, and side airbag on the front passenger
side.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<
Before transporting a child on the front
passenger seat, pay attention to the
safety information and follow the handling
instructions under Transporting children safely,

Technology for comfort, convenience and safety
96 refer to page54.
In certain sitting positions, teenagers and adults
can deactivate the front, knee and side airbag
on the front passenger side; when this occurs,
the indicator lamp for the front passenger air-
bags lights up. In these cases, change the sit-
ting position so that the front passenger airbags
are activated and the indicator lamp goes out.
If the desired status cannot be produced by
changing the sitting position, have the person
ride in the back. Do not place slip covers, seat
cushions, beaded mats, or other objects on the
passenger seat that are not specifically recom-
mended by BMW. Do not lay objects under the
seat which could press against the seat from
below. Otherwise, a correct evaluation of the
occupied seat surface cannot be assured.<
Operating state of front passenger
airbags
The indicator lamp for the front passenger air-
bags indicates the operational status of the
front, knee and side airbag on the front passen-
ger side depending on whether the seat is
occupied. The indicator lamp shows whether
the front passenger airbags are activated or
deactivated.
>The indicator lamp lights up when a child
properly seated in a child restraint system
intended for the purpose is detected on the
seat.
Front, knee and side airbag on the front
passenger side are deactivated.
Most child seats are detected by the
system. It is particularly advisable to
use child seats approved by NHTSA at the
time that the vehicle was produced. After
installing a child's seat, make sure that the indicator light for the front passenger air-
bags is illuminated. This indicates that the
system has detected the child's seat and
has deactivated the front passenger air-
bags.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
Front, knee and side airbag on the front
passenger side are activated.
>The indicator lamp does not light up when
the seat is empty.
The front, knee, and side airbags on the
front passenger side are not activated in
this case either.
Operational readiness of the airbag
system
Once the radio ready position is reached, the
warning lamp lights up briefly, thus indicating
the operational readiness of the entire airbag
system and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up from radio
ready state.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction; otherwise,
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<

Telephone overview
The concept
Your BMW is equipped with a mobile phone
preparation package. After a suitable mobile
phone has been paired with the vehicle once,
you can operate the mobile phone via iDrive, via
the button on the steering wheel, via the phone
keypad and by voice
*.
A mobile phone that has been paired with the
vehicle once is automatically detected again
with the engine running or the ignition switched
on as soon as it is brought inside the vehicle.
The logon data of up to four mobile phones can
be stored simultaneously. If several mobile
phones are detected simultaneously, then the
vehicle can be used to operate the mobile
phone that was most recently paired with it.
Using a phone in your vehicle
Using snap-in adapter*
The so-called snap-in adapter, a cradle for your
mobile phone, is inserted into the center arm-
rest. If the mobile phone is inserted into the
snap-in adapter, the battery is charged and the
mobile phone is connected to the external
antenna of the vehicle whenever the ignition
key is in the radio ready state or higher. This
assures better network reception and uniform
sound quality. Ask your BMW center which
mobile phones snap-in adapters are offered for.
To use the snap-in adapter, refer to page181.
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 communications
device can interfere with each other. In addition,
there is no assurance that the radiation gener-
ated during transmission will be discharged
from the vehicle interior. the vehicle with the keypad of the mobile
phone; otherwise, malfunctions can occur.
The mobile phone can be operated by means
of:
>the button on the steering wheel, refer to
page11
>the retracting telephone keypad, refer to
page179
>iDrive, refer to Initiating communication,
page184
>the voice command system
*, refer to
page23
For information on operating your mobile
phone, please consult the separate operating
instructions.
For your safety
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 comply with 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.
