Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. The sit-
ting position also plays an important role
together with the safety belts and airbags in
providing occupants with maximum levels of
passive safety in an accident. To ensure that
the safety systems operate with optimal effi-
ciency, 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
hold the steering wheel by its rim with hands at
the 9 o'clock and 3 o'clock positions, to mini-
mize the risk of injuries to your hands and arms
in the event of airbag deployment.
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
and does not rest feet or legs on the instrument
panel, otherwise leg injuries 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 airbag could
cause a serious or fatal injury.<
Even if you adhere to all the instructions, inju-
ries 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 page86.
Safety belt
Fasten your safety belt before starting any trip.
Airbags complement the safety belt as an addi-
tional 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 sys-
tems; larger children and adults using the safety
belts.
Never allow more than one person to wear a sin-
gle safety belt. Never allow infants or small chil-
dren 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 abdominal 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 shoulder belt
periodically to readjust the tension across your
lap in order to avoid a reduction in the retention
effect of the safety belt.<
For instructions on operating safety belts, refer
to page48.
Seats
Note before adjusting
Never attempt to adjust your seat while
operating the vehicle. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an
accident.

Before every drive, make sure that safety belts
are being worn at all of the occupied seats. Air-
bags complement the safety belt as an addi-
tional safety device, but they do not represent a
substitute.

Transporting children safely

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 chil-
dren 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 sys-
tem 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 pas-
senger seat, the airbags on the passenger's
side must be deactivated. Deactivating the front
passenger airbag is only possible on the Coupe.
Your BMW center will be glad to advise you.<
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle if the passenger airbag 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 supple-
mental 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 airbag'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 man-
ufacturer's instructions for installation
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 systems
are designed to be secured with a lap belt or
with the lap belt portion of a combination 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.
Child seat security
All of the rear belt retractors and the front pas-
senger's safety belt can be locked for mounting
and securing child-restraint systems.

system and allow the belt retractor to reel the
belt completely in.
Coupe: child-restraint system with
tether strap
If you use a child-restraint system with a tether
strap, two additional tether anchorage points
have been provided – refer to the arrows in the
illustration. Depending on the location selected
for sitting in the rear passenger area, attach the
tether strap to the corresponding anchorage
point to secure the child-restraint system, as
shown in the illustration below.
Each sitting position is fitted with a head
restraint.
The head restraint must be adjusted into the lowest possible position. Pass the tether strap
over the head restraint.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.<
LATCH child-restraint fixing system
LATCH: Lower Anchor and Tethers for CHil-
dren.
The rear outer sitting positions are provided
with anchors for a LATCH child-restraint fixing
system.
To fit the LATCH child-restraint fixing
system, follow the operating and safety
instructions of the system manufacturer.<
Access to anchorage points
The illustrations show the right rear seat as an
example. The outer anchorage points for the
LATCH child-restraint fixing system are identi-
fied by flags
*.
The anchorage points for the LATCH child-
restraint fixing system are identified by but-

Starting engine
Do not run the engine in closed rooms, as
otherwise the inhaling of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
select neutral position or position N and apply
the handbrake before leaving the vehicle with
the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.

>the engine fails to start on the first attempt,
for instance, if it is very hot or cold
>the engine is started at very low tempera-
tures, below approx. + 57/– 156, at high
altitudes, above 3,300 ft/1,000 m
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
