Data memory
Numerous electronic components in your vehi‐
cle contain data memories that store technical
information on the vehicle condition, events and faults, either temporarily or permanently.
This technical information generally docu‐
ments the state of a component, a module, a
system or the environment.▷Operating conditions of system compo‐
nents, such as filling levels.▷Status messages from the vehicle and its
individual components, such as wheel rpm/
speed, motion delay, transverse accelera‐
tion.▷Malfunctions and defects in important sys‐
tem components, such as lights and
brakes.▷Vehicle responses to special driving situa‐
tions, such as airbag deployment, use of

Safety belts
General information
Always make sure that safety belts are being
worn by all occupants before driving away.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
Seats with safety belt The vehicle has two seats, each of which is
equipped with a safety belt.
The shoulder strap's anchorage point will be
correct for adult seat occupants of every build
if the seat is correctly adjusted.
One person per safety belt
Never allow more than one person to
wear a single safety belt. Never allow infants or
small children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies
low around the hips in the lap area and does
not press on the abdomen. Otherwise, the belt
can slip over the hips in the lap area in a frontal
impact and injure the abdomen.
The safety belt must not lie across the neck,
rub on sharp edges, be routed over solid or
breakable objects, or be pinched.◀
Reduction of restraining effect
Avoid wearing clothing that prevents the
belt from fitting properly, and pull the shoulder
belt periodically to readjust the tension across
your lap; otherwise, the retention effect of the
safety belt may be reduced.◀Seite 50ControlsAdjusting50

The right place for children Note Children in the vehicle
Do not leave children unattended in the
vehicle; otherwise, they could endanger them‐
selves and other persons, e.g., by opening the
doors.◀
Children on the front passenger seat Should it be necessary to use a child restraint
fixing system on the front passenger seat,
make sure that the front and side airbags on
the front passenger side are deactivated. Auto‐
matic deactivation of front passenger airbags,
refer to page 93.
Deactivating the front passenger airbags
If a child restraint fixing system is used in
the front passenger seat, the front passenger
airbags must be deactivated; otherwise, there
is an increased risk of injury to the child when
the airbags are triggered, even with a child re‐
straint fixing system.◀Transport children in suitable child re‐
straint fixing systems
Only transport children younger than 13 years
of age or shorter than 5 ft/150 cm in child re‐
straint fixing systems suitable for the age,
weight and size of the child; otherwise, there is
an increased risk of injury in an accident.
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
fixing system can no longer be used, due to
their age, weight and size.◀
Installing child restraint
fixing systems
Notes Manufacturer's information for child re‐
straint fixing systems
To select, mount and use child restraint fixing
systems, observe the information provided by
the system manufacturer; otherwise, the pro‐
tective effect can be impaired.◀
Standard child restraint systems are designed
to be secured with a lap belt or with the lap-
belt section of a lap-and-shoulder belt. Incor‐
rectly or improperly installed child restraint
systems can increase the risk of injury to chil‐
dren. Always follow the installation instructions
for the system with the greatest care.
On the front passenger seat Check the deactivation of the passenger
airbag
After installing a child restraint fixing system
on the passenger seat, make sure that the
front and side airbags on the passenger side
have been deactivated; otherwise, there is an
increased risk of injury when the airbags are
deployed.◀Seite 55Transporting children safelyControls55

SafetyVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Airbags The following airbags are located under the
marked covers:1Front airbags2Side airbags in the seat backrests3Knee airbag
Front airbags
Front airbags help protect the driver and pas‐
senger by responding to frontal impacts in
which safety belts alone cannot provide ade‐
quate restraint.
Side airbags
In a lateral impact, the side airbag protects the
side of the body in the chest area.
Knee airbag
The knee airbag supports the legs in a frontal
impact.
Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary
hearing impairment in sensitive individuals.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to
keep the danger of injury to your hands or
arms as low as possible if the airbag is trig‐
gered.▷There should be no people, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Keep the dashboard and window on the
front passenger side clear, i.e., do not
cover with adhesive labels or coverings,
and do not attach holders such as for navi‐
gation instruments and mobile phones.▷Make sure that the front passenger is sit‐
ting correctly, i.e., keeps his or her feet and
legs in the footwell; otherwise, leg injuries
can occur if the front airbag is triggered.Seite 92ControlsSafety92
Online Edition for Part no. 01 40 2 954 104 - II/15

▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as
jackets, over the backrests.▷Make sure that passengers do not lean
their heads against the side airbag; other‐
wise, serious injuries could result if the air‐
bag suddenly deployed.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system.
This also applies to the covers of the steer‐
ing wheel, the dashboard and the seats.◀
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered;
otherwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explo‐
sives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or
undesired triggering of the airbag, either of
which could result in injury.◀
Warning notices and information about the air‐
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body. The front and side
airbags on the front passenger side are acti‐
vated or deactivated accordingly by the sys‐
tem.
The indicator lamp above the interior rearview
mirror shows the current status of the passen‐
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Passenger feet in the footwellMake sure that the front passenger
keeps his or her feet in the footwell; otherwise,
the front passenger airbags may not function
properly.◀
Child restraint fixing system in the front
passenger seat
Before transporting a child on the passenger
seat, read the safety and operating instructions
under Transporting children safely, refer to
page 55.◀
Malfunction of the automatic
deactivation system
The front passenger airbags may be deacti‐
vated if adolescents and adults sit in certain
positions; the indicator lamp for the front pas‐
senger airbags comes on. In this case, change
the sitting position so that the front passenger
airbags are activated and the indicator lamp
goes out. If the desired airbag status cannot be
achieved by changing the sitting position, do
not transport the passenger in the vehicle.
To make sure that occupation of the seat
cushion can be detected correctly:▷Do not attach seat covers, seat cushion
padding, ball mats or other items to the
passenger seat unless they are specifically
recommended by BMW.▷Do not place any objects on the front pas‐
senger seat.▷Do not place objects under the seat that
could press against the seat from below.Seite 93SafetyControls93

Status of passenger airbags
The indicator lamp for the front passenger air‐
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica‐
tor lamp shows whether the passenger airbags
are activated or deactivated.
▷The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is de‐
tected on the seat or the seat is empty.
The front and side airbags on the front
passenger side are not activated. Most
child seats are detected by the system. Es‐
pecially the child seats required by NHTSA
at the time that the vehicle was manufac‐
tured. After installing a child seat, make
sure that the indicator lamp for the front
passenger airbags lights up. This indicates
that the child seat has been detected and
the front passenger airbags are not acti‐
vated.▷The indicator lamp does not light up when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat. The front and front passenger air‐
bags on the front passenger side are acti‐
vated.Operational readiness of airbag
system
When the ignition, refer to page 58, is switched
on, the warning lamp comes on briefly to indi‐
cate that the entire airbag system and the belt
tensioners are operational.
Airbag system malfunction
▷The warning lamp does not light up when
the ignition is switched on.▷Warning light remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not func‐
tion as intended even if a sufficiently severe
accident occurs.◀
Flat Tire Monitor FTM The conceptThe system detects a pressure loss in a tire on
the basis of speed differences between the in‐
dividual wheels during a trip.
In the event of pressure loss, the rolling cir‐
cumference changes and, thus, the rotating
speed of the affected wheel. This change is
detected and is reported as a flat tire.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
