Adjustments
Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fati gue-free driving. In con-
junction with the safe ty belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensu re 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 page 48.
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
airbags and the seat occupant.
Do not use the cover of the front airbag on the
passenger side as a st orage area. Make sure
that the passenger is sitting correctly, e.g.
keeping his or her feet or legs in the footwell
and not on the dashboard; otherwise, leg inju-
ries can occur if the front airbag deploys.
Make sure that passengers do not lean their
heads against the side airbag; otherwise, seri-
ous injuries could result if the airbag 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 e ffect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page 85.
Safety belt
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the
safety belt as an additi onal safety device, but
they do not represent a substitute.
Your vehicle has two 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 be lt 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 withou t 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-bo dy area taut, otherwise
its restraining effect could be impaired. <
Safety belts, refer to page 44.
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 passenger seat as well, do not incline
the backrest too far to th e rear while the vehicle
is being driven, otherwise there is a danger in
the event of an accident of sliding under the
safety belt, eliminating the protection normally
provided by the belt. <
Note the information on safety belt damage on
page 45.

Safety belts
Observe the adjustment instructions on
page 41 to ensure the best possible per-
sonal protection. <
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the

they do not repres ent a substitute.

Transporting children safely
48
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 on the passenger seat
Always transport children under the age
of 13 or smaller than 5 ft/150 cm in a
child-restraint system suitable for their age,
weight and size, and with the passenger airbag
deactivated. Otherwise, there is an increased
risk of injury in the event of an accident or if the
airbags deploy. <
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-restr aint system that is
appropriate for their age, size and weight.
For more information on automatic deactivation
of the passenger airbags refer to page 86.
Installing child-restraint
systems
After installing a child-restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated; otherwise, there is an increased
risk of injury if the airbags deploy.
Observe the child-restraint system manufac-
turer's instructions when selecting, installing
and using child-restraint systems. Otherwise
the protective effect may be diminished. <
Standard child-restraint systems are designed
to be secured with a lap be lt or with the lap-belt
section of a lap-and-shou lder belt. Incorrectly
or improperly installed child-restraint systems
can increase the risk of injury to children.
Always follow the installa tion instructions for
the system with the greatest care.
On the passenger seat
After installing a child-restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated, otherwise there is an increased
risk of injury if the airbags deploy. <
Seat position
Before installing a child-restraint system, move
the passenger seat as far back and up
* as pos-
sible to obtain the best possible position for
the belt.
Backrest width*
The backrest width of the passenger's
seat must be at its widest possible set-
ting. Do not change the setting after installing
the child seat. Otherwise the child seat's stabil-
ity on the passenger's seat is limited. <
1. Adjust the backrest width to its widest set-
ting, refer to page 43.
2. Install the child seat.
Child seat security
The safety belt for the passenger can be locked
to prevent it from being pulled out when it is
used to secure child-restraint systems.

The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale 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 malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure 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
telltale after replacing 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 function properly.
Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wh eels depending on the
speed at which you are driving. When you are
driving at low speeds, power steering provides
more support, i. e. little effort is needed to turn
the wheels. Power steering support lessens as
your speed increases.
The system works automatically.
Malfunction
Malfunctions are displayed via Check Control
Airbags
The following airbags are located under the
marked covers:
1 Front airbags
2 Side airbags in the seat backrests
3 Knee airbag
Protective action
Observe the adjustment instructions on
page 41 to ensure the best possible per-
sonal protection. <
The front airbags help protect the driver and
passenger by responding to frontal impacts in
which safety belts alone cannot provide ade-
quate restraint. When needed, the side airbags
help provide protection in the event of a side
impact. The relevant side airbag supports the
head and the side upper body area.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in
minor accidents 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.
Keep the dashboard and window on the pas-
senger side clear, i.e. do not cover with adhe-
sive labels or coverings, and do not attach hold-
ers such as for navigation instruments and
mobile phones.
Do not attach seat cove rs, cushions or other
objects to the front seats that are not specifi-
cally approved for seats with integral side air-
bags. Do not hang items of clothing such as
coats or jackets over the backrests.

Technology for driving comfort and safety
86
Do not attempt to remove
the airbag retention
system from the vehicle. Do not modify the indi-
vidual components of the system or its wiring in
any way. This includes the upholstered covers
of the steering wheel, the dashboard and the
seats. Do not attempt to remove or dismantle
the steering wheel.
Do not touch the individual components imme-
diately 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, remo val and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and th at has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesi red airbag activation,
either of which could resu lt in personal 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 passenger
seat is occupied by meas uring the resistance of
the human body. Front, knee and side airbags
on the passenger side ar e activated or deacti-
vated accordingly.
Make sure that the passenger keeps his
or her feet in the footwell; otherwise, the
passenger airbags may not function properly. <
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.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, see page 48.
Malfunction of the automatic
deactivation system
The front, knee and side airbags can also be
deactivated by adolescents and adults sitting in
certain positions; the in dicator lamp for the pas-
senger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the pa ssenger airbags are acti-
vated and the indicator la mp goes out. If the
desired airbag status cannot be achieved by
changing the sitting posi tion, do not transport
the passenger in the vehicle.
To make sure that occupa tion of the seat cush-
ion can be detected correctly:
> Do not attach seat covers, seat cushion
padding, ball mats or other items to the pas-
senger seat unless they are specifically rec-
ommended by BMW.
> Do not place any items under the seat which
could press against the seat from below. <
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front, knee and side airbags in accordance with
whether and how the passenger seat is occu-
pied. 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
detected on the seat or the seat is empty.
The front, knee and side airbags for the pas-
senger are not activated.
Most child seats are detected by the sys-
tem, especially child seats required by the
NHTSA at the time of vehicle production.

After mounting a child seat, ensure that the
indicator lamp for the pa ssenger airbag is lit.
It indicates that the child seat has been
detected and that th e passenger airbags
are deactivated.
> The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on
the seat.
The front, knee and passenger airbags for
the passenger are activated.
Operational readiness of airbag system
As of radio readiness, refer to page 50, the
warning lamp comes on br iefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
> Warning lamp does not light up at radio
readiness or beyond.
> Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay, otherwise
there is the risk that th e system will not function
as intended even if a sufficiently severe acci-
dent occurs. <
