Indicator and warning
lamps
Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
ignition or start the engine. They each light
up once for different periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving,
usually accompanied by a Check Control
message. You will find more details on the
specified pages.
Fixed indicator and warning lampsColors The indicator and warning lamps can light
up in different colors and combinations.

Sitting safely
The ideal sitting position can make a vital
contribution to relaxed, fatigue-free driving.
The sitting position also plays an important
role together with the safety belts and air-
bags in providing occupants with maximum
levels of passive safety in an accident. To
ensure that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the
following section.
For additional information on transporting
children safely, refer to page 51.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by
its rim with hands at the 9 o'clock and
3 o'clock positions, to minimize the risk of
injuries to your hands and arms in the event
of airbag deployment.
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 front passenger side as a storage area.
Make sure that the front passenger is sit-
ting correctly and does not rest feet or legs
on the instrument panel, otherwise leg inju-
ries can occur if the knee and front airbags
are triggered.
Never let an occupant's head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild – usually tempo-
rary – hearing loss in extremely sensitive
individuals.
For airbag locations and additional infor-
mation on airbags, refer to page 81.
Sitting safely with safety belts
Fasten your safety belt before starting any
trip. Airbags complement the safety belt as
an additional safety device, but they do not
represent a substitute.
Your vehicle has four seats that are all
equipped with a safety belt.
At all times, occupants should sit
upright and be properly restrained:
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
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.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder. Do not allow
the belt to rest against hard or fragile
objects. Otherwise, in the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal injury.
Avoid wearing clothing that prevents the
belt from fitting properly and pull the lap
belt periodically to readjust the tension
across your shoulder in order to avoid a
reduction in the retention effect of the
safety belt.<
For instructions on operating safety belts,
refer to page 47.

Safety belts

trip. Airbags complement the safety belt as
an additional safety device, but they do not
represent a substitute.
Fastening
Make sure you hear the latch plate engage
in the belt buckle.
Please fasten safety belt
warning lamp:
Lights up until the driver and front
passenger have fastened their safety belts.
Depending on the model, a signal
* sounds
or a message
* appears on the Control Dis-
play at the same time.
The warning is also issued when the driver
or front passenger removes his or her
safety belt while driving.
The warning can also take place if
objects are placed on the passenger
seat.<
Releasing
1.Hold the belt firmly
2.Press the red button in the belt buckle
3.Guide the belt into its reel.
The shoulder strap's anchorage point will
be in the correct position for adults of every
build if the seat is correctly adjusted, refer
to page 43.
Damage to safety belts
If the safety belts are damaged or
stretched in an accident: have the
entire belt system, including the tensioning
mechanisms, replaced at your BMW cen-
ter. Have the belt anchorage points
inspected for damage at the same time.
Failure to observe this precaution may pre-
vent the safety belts from effectively pro-
viding optimal protection when needed.<
Heated seats
The system regulates the temperatures of
the seat cushion and backrest.
The temperature setting progresses one
step through its control sequence each
time you press the button.
To switch off:
Maintain pressure on the button for several
seconds.

Transporting children safely
The right place for children
Children always in the rear
Accident research shows that the safest
place for children in a vehicle is in the rear
seat.
Older children should be tightly secured
with a safety belt, after they have outgrown
a booster seat that is appropriate for their
age, height and weight.
Child-restraint system in the rear
Children under 13 years of age and
children less than 5 ft/150 cm tall
should always ride in the rear and the
restraint systems should be secured with
the vehicle's safety belts.<
Younger children should be secured in an
appropriate forward-facing child-restraint
system that has first been properly
secured. We strongly urge you to carefully
read and comply with the instructions for
installation and use provided by the child-
restraint's manufacturer whenever you use
such a device.
All rear sitting positions in your vehicle
meet the recommendations of SAE J1819,
an industry-recommended practice for
securing child-restraint systems in motor
vehicles.
Exception for front passenger seat
Should it become necessary to use
a child-restraint system on the front
passenger seat, the airbags on the passen-
ger's side must be deactivated. Deactivat-
ing the passenger airbags is only possible
on the Coupe. Your BMW center will be
glad to advise you. restraint system in the front passen-
ger seat of this vehicle if the passenger air-
bag is not deactivated. If you do so, the
child could be severely injured when the
airbag is triggered.
Your vehicle is equipped with an airbag
supplemental restraint system for the front
passenger. Because the backrest on any
rearward-facing child-restraint system – of
the kind designed for infants under 1 year
and 20 Ibs./9 kg – would be within the air-
bag's deployment range, you should never
mount such a system in the front passenger
seat, since the impact of the airbag against
the child restraint's backrest could lead to
serious or fatal injuries.<
Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Observe the child-restraint system
manufacturer's instructions for instal-
lation and use. Otherwise the degree of
protection can be reduced.
After an accident, have all parts of the
child-restraint system and of the relevant
vehicle safety belt system checked by a
BMW center and replaced if necessary.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap 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.

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front pas-
senger
2Coupe: head airbags
3Front side airbags
4Knee airbag for front passenger
5Knee airbag for driver
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone can-
not provide adequate restraint. When
needed, the head and side airbags help
provide protection in the event of a side
impact. The side airbags help restrain the
side of the occupant's upper torso, and the
head airbags help support the head while
also helping provide protection against any
objects penetrating into the passenger
compartment.
The airbags are deliberately not triggered
in every impact situation, e.g. less severe
accidents, certain rollover conditions, or
rear-end collisions.
For information on the correct sitting posi-
tion, refer to page 42.
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild hearing loss in
extremely sensitive individuals. This effect
is usually only temporary.Do not apply adhesive materials to
the cover panels of the airbags, cover
them or modify them in any other way.
Do not attempt to remove the airbag reten-
tion system from the vehicle. Never modify
or tamper with either the wiring or the indi-
vidual components in the airbag system.
This category includes the upholstery in the
center of the steering wheel, on the instru-
ment panel, the side trim panels on the
doors and on the Coupe the roof pillars
along with the sides of the headliner.
Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been trig-
gered, because there is a danger of burns.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem is triggered in response to an accident,
you should always entrust all inspection,
repair and dismantling operations to your
BMW center. Unprofessional attempts to
service the system could lead to failure in
an emergency or undesired airbag activa-
tion, either of which could result in personal
injury.<
Airbag warning information is also provided
on the sun visors.

Technology for comfort, convenience and safety

Airbag system operational
The airbag warning lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The warning lamp goes out after a few sec-
onds.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem not responding in the expected man-
ner to an impact occurring within its normal
response range.<
There is a malfunction in the airbag
system when:
>The warning lamp does not light up as
of ignition key position 1
>The warning lamp remains on continu-
ously
>The warning lamp lights up while the
vehicle is being driven.
Convertible:
Rollover protection system
The rollover protection system is automati-
cally activated in the event of an accident
or a critical driving situation, extreme incli-
nation on the longitudinal or transverse
axis, or loss of ground contact. The rollover
bars located behind the rear head
restraints move out within fractions of a
second.As a supplement to the rollover bar inte-
grated in the windshield frame, the rollover
protection system ensures that all vehicle
occupants have the necessary headroom.
Always keep the path of movement of
the rollover protection system clear.
In less severe accidents, you are protected
by the fastened safety belt and, depending
on the severity of the accident, the belt ten-
sioner and the multistage airbag restraint
system.<
Lowering
If the protection function was not required
after automatic activation, the rollover pro-
tection system can be lowered again.
No tools are necessary for this purpose.
1.Press the release backwards and hold
in that position
2.Press the rollover bar halfway down
from above
3.Let go of the release
4.Press the rollover bar down until it
snaps into place
5.Use the same procedure for the second
rollover bar.
Have the rollover protection system
checked after unexpected triggering.
