Transporting children safelyVehicle 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 sys‐
tems.
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. Automatic de‐
activation of front passenger airbags, refer to
page 74.
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 restraint
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. Incorrectly or
improperly installed child restraint systems can
increase the risk of injury to children. Always fol‐
low 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.◀
Seat position
Before installing a child restraint fixing system,
move the passenger seat as far back and as
high as possible to obtain the best possible po‐
sition for the belt.Seite 43Transporting children safelyControls43

▷Do not hang pieces of clothing, such as jack‐
ets, over the backrests.▷Make sure that passengers do not lean their
heads against the side airbag; otherwise, se‐
rious injuries could result if the airbag sud‐
denly 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 steering
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; oth‐
erwise, 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 explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired 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 system.
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 footwell
Make 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 43.◀
Malfunction of the automatic
deactivation system
The front passenger airbags may be deactivated
if adolescents and adults sit in certain positions;
the indicator lamp for the front passenger air‐
bags 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 cush‐
ion can be detected correctly:▷Do not attach seat covers, seat cushion pad‐
ding, ball mats or other items to the passen‐
ger seat unless they are specifically recom‐
mended 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.

The indicator lamp for the front passenger air‐
bags indicates the operating status of the front
and side airbags on the front passenger side de‐
pending on the seat occupation. The indicator
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 passen‐
ger side are not activated. Most child seats
are detected by the system, Especially the
child seats required by NHTSA at the time
that the vehicle was manufactured. After in‐
stalling a child seat, make sure that the indi‐
cator lamp for the front passenger airbags
lights up. This indicates that the child seat
has been detected and the front passenger
airbags are not activated.▷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 46, 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 lamp 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 function
as intended even if a sufficiently severe accident
occurs.◀
Flat Tire Monitor FTM
The concept
The 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 circum‐
ference 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; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.Seite 75SafetyControls75
