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 page44.
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 page72.
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 page37.
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 page40.
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

Using the M Mobility System
To repair a flat tire with the M Mobility System,
proceed as follows:
>Fill the sealant, refer to page132.
>Distribute the sealant, refer to page132.
>Produce the tire inflation pressure, refer to
page132.
Filling the sealant
Strictly follow the specified sequence,
otherwise the sealant may escape under
high pressure.<
1.Shake the sealant bottle.
2.Screw connection hose 9 onto the connec-
tor of the sealant bottle.
3.Ensure that screw 8 on the pressure gauge
is closed.
4.Unscrew the dust cap from the valve of the
defective wheel and screw filling hose 2 of
the sealant bottle onto the valve.
5.Insert the sealant bottle into the housing of
the compressor so that the bottle is upright.
6.Ensure that the compressor is switched off,
position 0.
7.Insert connector 3 into the cigarette lighter
socket in the interior of the vehicle, refer to
page90.
8.With the ignition switched on:
Switch on the compressor and let it run for
approx. 3 minutes to fill the sealant. The
inflation pressure of the tire after filling is
unimportant.
9.Switch off the compressor.
10.Detach the hoses from the sealant bottle
connector and from the tire valve.Return the M Mobility System to its storage
location in the vehicle.
Distributing the sealant
Immediately drive approx. 2 miles/3 km to
evenly distribute the sealant in the tire.
Do not exceed a speed of 35 mph/
60 km/h. If possible, do not fall below a
speed of 12 mph/20 km/h.<
Producing the tire inflation pressure
1.After driving approx. 2 miles/3 km, stop at a
suitable location.
2.Connect connection hose9 of the com-
pressor directly to the tire valve.
3.Insert connector 3 into the cigarette lighter
socket in the interior of the vehicle.
4.Adjust the tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on, pro-
ceed as follows:
>To increase the inflation pressure:
Switch on the compressor, position I. To
check the current inflation pressure set-
ting, briefly switch off the compressor.
Do not let the compressor run for
more than 10 minutes, otherwise the
device will overheat and may be dam-
aged.<
>To reduce the inflation pressure: turn
screw 8 on the pressure gauge.
If the inflation pressure is not maintained,
drive the vehicle a second time, refer to
Distributing the sealant. Then repeat steps 1 to
4.
Use of the M Mobility System may be ineffec-
tual for tire damage larger than approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page135, or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not be made roadworthy with the M Mobility
System.<
The tire inflation pressure must be at least
29 psi/200 kPa. If it is not, do not continue
driving.<

a tow truck with a flat bed.
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
