Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. In con-
junction with the safety belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensure that the safety sys-
tems operate with optimal efficiency, we
strongly urge you to observe the instructions
contained in the following section.
For additional information on transporting chil-
dren safely, refer to page52.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
grip the steering wheel on the rim, with your
hands in the 3 o'clock and 9 o'clock positions,
to minimize the risk of injury to the hands or
arms in the event of the airbag being triggered
off.
No one and nothing is to come between the air-
bags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passenger is sitting correctly,
e.g. not resting feet or legs on the dashboard,
otherwise leg injuries can occur if the front air-
bag is triggered.
Make sure that passengers do not lean their
heads against the side or head airbags, other-
wise serious injuries could result if the airbags
suddenly deployed.<
Even if you follow all the instructions, injuries
resulting from contact with airbags cannot be
fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page90.
Head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Head restraints, refer to page44.
Safety belt
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the
safety belt as an additional safety device, but
they do not represent a substitute.
Your vehicle has four seats, each of which is
equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the belt in the lap area sits
low across the hips and does not press against
the abdomen.
The safety belt must not rest against the throat,
run across sharp edges, pass over hard or frag-
ile objects or be pinched. Fasten the safety belt
so that it sits as snugly as possible against the
lap and shoulder without being twisted. Other-
wise the belt could slide over your hips and
injure your abdomen in the event of a frontal
collision.
Avoid wearing bulky clothing and regularly pull
the belt in the upper-body area taut, otherwise
its restraining effect could be impaired.<
Safety belts, refer to page48.
Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an

accident.
On the front passenger seat as well, do not
incline the backrest too far to the rear while the
vehicle is being driven, otherwise there is a dan-
ger in the event of an accident of sliding under
the safety belt, eliminating the protection nor-
mally provided by the belt.<
Comply with the instructions on head restraint
height on page44, and on damaged safety
belts on page48.

transporting anyone on that seat. Otherwise,
the passenger will be without protection from
the head restraint.<
Front active head restraints
In a rear collision of a sufficient strength, the
active head restraint reduces the distance to
the head.
Do not use seat or head restraint covers
that could impair the function of the active
head restraint. Otherwise, the protective func-
tion of the active head restraint will not be
ensured and its full potential in reducing the risk
of injury in the event of a rear collision may not
be realized.
In the event of malfunctions, deactivation or
triggering of the active head restraints, have the
testing, repair and removal executed only by a
BMW center or a workshop that works accord-
ing to repair procedures of BMW with corre-
spondingly trained personnel and that has the
required explosives licenses. Unprofessional
attempts to work on the system could lead to
failure in an emergency or to undesired airbag
activation, either of which could result in per-
sonal injury.<
For technical reasons, the head restraint
cannot be removed.<

restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly.<
Coupe: belt hand-over
The concept
The belt hand-over makes it easier for you to
fasten your safety belt. When you close the
door and switch on radio readiness or the igni-
tion, the belt hand-over extends automatically
and presents the in a position that is convenient
for fastening it around you. After you have fas-
tened your safety belt, the belt hand-over
retracts to its original position.
Even if you have not yet fastened your safety
belt, the belt hand-over will retract if you:
>Wait for more than approx. one minute
>Open the corresponding door
>Start to drive.
Closing the respective door reactivates the belt
hand-over if the ignition or radio readiness is on.
Front passenger's seat
The belt hand-over will extend only if the seat is
occupied and after the front passenger's door is
closed.
Pinch protection system
If the belt hand-over encounters resistance on
moving in or out, it moves back slightly in the
opposite direction and stops in this position. To reactivate the belt hand-over: open and close
the door or switch the ignition off and on.
Although there is a pinch protection sys-
tem, always check that the maneuvering
area of the belt hand-over is clear. Otherwise it
cannot be ensured that the system will stop
moving in certain extreme situations.<
Mirrors
Exterior mirrors
The front passenger's mirror is more con-
vex than the driver's mirror. The objects
seen in the mirror are closer than they appear.
Do not gauge your distance from traffic behind
you on the basis of what you see in the mirror;
otherwise there is an increased risk of an acci-
dent.<

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child-restraint systems
appropriate for their age, weight and size. Oth-
erwise there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restraint system that is
appropriate for their age, size and weight.
Exception for front passenger seat
Should it be necessary to use a child-
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, even
with a child-restraint system.<
For more information on automatic deactivation
of the front passenger airbags refer to page90.
Installing child-restraint
systems
Observe the child-restraint system man-
ufacturer's instructions when selecting,
installing and using child-restraint systems.
Otherwise the protective effect may be dimin-
ished.<
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 follow the installation instructions for
the system with the greatest care.
On the front passenger seat
After installing a child-restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated, otherwise there is an
increased risk of injury if the airbags deploy.<
Backrest width*
The backrest width of the front passen-
ger's seat must be at its widest possible
setting. Do not change the setting after install-
ing the child seat. Otherwise the child seat's
stability on the front passenger's seat is lim-
ited.<
1.Adjust the backrest width to its widest set-
ting, refer to page44.
2.Install the child seat.
Child seat security
The rear safety belts and the front passenger's
safety belt can be prevented from being pulled
out in order to fasten child-restraint systems.
To lock the safety belt
1.Secure the child-restraint system with the
belt.
2.Pull the belt strap all the way out.

LATCH child-restraint fixing
system
LATCH: Lower Anchors and Tethers for CHil-
dren.
To install and use the LATCH child
restraint system, follow the operating and
safety instructions provided by the manufac-
turer of the system, otherwise the protective
function of the seat may be compromised.<
Before installing the child seat, pull the belt out
of the area for the child-restraint fixing system.
Ensure that both lower LATCH anchors
are correctly engaged and that the child
restraint system is resting firmly against the
backrest, otherwise the protective function of
the seat may be compromised.<
The anchor points for the lower LATCH
anchors are located behind the labeled protec-
tive caps.
Coupe: child-restraint system with
tether strap
Use the top tether anchors to secure
child-restraint systems only, otherwise
the anchors could be damaged. there are two additional anchors, see arrows.
Coupe: placement of the tether strap
Make sure the upper retaining strap does
not run over sharp edges and is not
twisted as it passes to the top anchor. Other-
wise the strap will not properly secure the child-
restraint system in the event of an accident.<
