Airbags
At all times, occupants should sit 
upright and be properly restrained 
(infants and small children in appro-
priate child restraint systems; larger 
children and adults using the safety 
belts). Never let an occupant's head 
rest near or on a side airbag because 
the inflating airbag could cause a 
serious or fatal injury. Please note that 
the word "Airbag" imprinted on the door 
trim panel indicates the airbag's loca-
tion. 
Accident research shows that the 
safest place for children in an 
automobile is in the rear seat. However, 
a child sitting in the rear seat and not 
properly restrained may place his or her 
head on or near the airbag, if so 
equipped. For example, a child Ñ even 
though belted Ñ may fall asleep with his 
or her head against the side airbag. It 
may be difficult for a driver to ensure 
that children in the rear seat will remain 
properly positioned at all times and not 
place their heads on or near the side 
airbag. Therefore, we recommend that 
the rear seat side airbags, if so 
equipped, be deactivated if children will 
travel in the rear seat. 
The rear seat side airbags may already 
have been deactivated, either at the 
time of manufacture or by a BMW 
center. Labels in the door opening 
should indicate the status of your rear 
seat side airbags. If you are uncertain of 
their status, or wish to have the airbags 
activated or deactivated, please 
contact your BMW center.<
Even when all these guidelines are 
observed, there is still a small residual 
risk of injuries to the face, hands and 
arms occurring in isolated instances. 
The ignition and inflation noise may 
induce a mild temporary hearing loss in 
sensitive individuals.
For additional information concerning 
the airbag system, refer to pages 159 
and 189.This is the right way for a child to sit in 
a child restraint when rear side airbags 
(arrow) are provided.

LATCH attachment of the child 
seat
*
The mounts for the LATCH child-
restraint system are located at the posi-
tions indicated by two colors, which are 
not visible from the outside. 
The illustration show the left rear seat.
To mount the LATCH attachment 
of the child-restraint system, 
please follow the manufacturer's oper-
ating and safety precautions.<
Carefully press the brackets through 
the separating lines in the upholstery at 
the marked spots.46cus028
Leave the rear safety belts in the 
holders if they are not needed to 
avoid unwanted movement from the 
safety belts at high speeds.<

Transporting children safelyCommercially available child seats 
complying with the legal standard are 
designed to be secured with a seat belt 
or with the seat belt portion of a combi-
nation lap/shoulder belt. 
Improperly or inadequately installed 
restraint systems can increase the risk 
of injury to children. Always read and 
follow the instructions that come with 
the system.
If you use a child restraint system with a 
tether strap, two additional tether 
anchorage points (refer to the arrows in 
the illustration) have been provided. 
They are located under the convertible 
top compartment.
Depending on the location selected for 
seating in the rear passenger area, 
attach the tether strap to the corres-
ponding anchorage point to secure the 
child restraint system.46cus001
Lift the respective headrest and pass 
the tether strap between the headrest 
and the seat back.
Adjust the tether strap according to the 
child restraint manufacturer's instruc-
tions.
Before installing any child restraint 
device or child seat, please read 
the following: 
Never install a rearward-facing child 
restraint system in the front passenger 
seat of this vehicle. 
Your vehicle is equipped with an airbag 
supplemental restraint system for the 
front passenger. Because the backrest 
on any rear-facing child restraint 
system (of the kind designed for infants 
under 1 year and 20 lbs./9 kg) would be 
within the airbag's deployment range, 
you should never mount such a device 
in the front passenger seat, as the 
impact of the airbag against the child 
restraint's backrest could lead to 
serious or fatal injuries. 
If it is necessary for a child (not an 
infant) to ride in the front seat, certain 
precautions should be taken. First, 
move the passenger seat as a far away 
from the dashboard as possible. This 
important precaution is intended to 
maximize the distance between the 
airbag and the child. Older children 
should be tightly secured with the 
safety belt. Younger children should be 
secured in an appropriate forward-
facing child restraint system that has 
first been properly secured with a 
safety belt. 
Never install a rear-facing child restraint 
system in the front passenger seat. 
We strongly urge you to carefully read 
and observe the instructions for instal-
lation and use provided by the child 
restraint's manufacturer whenever you 
use such a device. 
Allways ensure that all occupants (of all 
ages) remain properly and securely 
restrained at all times.c
All rear seating positions in your vehicle 
meet the recommendations of SAE 
J1819, an industry recommended 
practice for securing child restraint 
systems in motor vehicles.

Rollover protection systemIn the event of an accident or some 
other critical driving situation (extreme 
tilting in the longitudinal or transverse 
axis, loss of contact with the ground), 
the rollover protection system will be 
automatically activated. The protective 
bars located in the rear headrests 
extend within fractions of a second.
In addition to the integrated rollover bar 
in the windshield frame, the rollover 
protection system gives all the vehicle 
occupants the necessary headroom.
Always keep the travel path clear 
for the rollover protection system. 
Under no circumstances should you 
cover the headrests. 
In the event of less serious accidents, 
the safety belt will protect you and, 
depending on the severity of the acci-
dent, so will the safety belt tensioner 
and the multi-stage airbag restraint 
system.c
If, after being automatically triggered, 
the protective function is not needed, 
then the rollover protection system can 
be lowered back into place. No special 
tool is needed for this.
1 Using a screwdriver from the on-
board tool kit, remove the cover 
panel; to do this, position the screw-
driver under the notch (arrow).46cde007
2Pull the lever (arrow) toward the front 
of the car and hold it in this position.46cde006

Rollover protection system3 Continue pressing down on the 
protective bar (1) from above until 
you hear it click into place. 
4 Replace the cover panel and press 
down firmly.
5 Press the rear section of the headrest 
closed (2).46cde035
Do the same for the second protective 
bar. If you are not familiar with these 
procedures, consult your BMW center.
Have the rollover protection system 
checked by your BMW center after it 
has been inadvertently triggered.
Do not move the convertible top 
under any circumstances if the 
rollover protection system has 
extended. 
Do not use the rear headrests as 
storage shelves. 
Absolutely no modifications are to be 
made to any of the rollover protection 
system's individual components or any 
of its wiring. 
Only your BMW center is to carry out 
any work on the rollover protection 
system. 
Work done on the system that is carried 
out improperly could lead to failure in 
an emergency or accidental airbag acti-
vation. 
To have the system checked and to 
ensure long-term operation: be sure to 
adhere to the Service Interval Display 
for maintenance intervals. Every 2 years 
at the latest, the rollover protection 
system must be inspected by a BMW 
center.c

Important safety notices 
Do not attempt to remove the gas 
generators of the airbag supple-
mental restraint system from the 
vehicle. Testing and servicing must be 
performed by trained technicians only. 
In the event of a malfunction, deactiva-
tion, or triggered actuation (as a 
response to an accident) of the airbag 
restraint system, consult your BMW 
center for repairs or service operations. 
46cde048
Do not modify or tamper with either the 
wiring or the individual components in 
the airbag system. These include the 
padded steering wheel hub, the instru-
ment panel, the side trim panels of the 
front doors and in the rear. Do not apply 
adhesive materials to these compo-
nents or cover them over or alter them 
in any other way. Do not attempt to 
remove or dismantle the steering 
wheel. 
To ensure compliance with official 
safety regulations, entrust disposal of 
airbag generators to a BMW center. 
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.<
