Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch, otherwise you could suffer
burns.<
When working on electrical systems,
always begin by switching off the con-
sumer in question, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<

Replacing components
128 For care of the headlamps, please follow the
instructions in the chapter entitled 'Care'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Control elements, display components, part of
the exterior lighting and other interior equip-
ment in your vehicle are equipped with covered
light-emitting diodes as light sources. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours, otherwise this could cause
irritation to the retina.<
Xenon lamps
These bulbs have a very long service life and are
highly unlikely to fail.
Have any work on the xenon lamp system,
including bulb replacements, performed
o n ly b y a BM W c e n t e r o r a w o r k s h o p t h a t w o r k s
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<

Repairing a flat tire with the
M Mobility System
To repair a flat tire, your BMW M3 includes an
M Mobility System. With this system you can
apply a sealant to the inside of the tire to seal
the damaged section, restore the tire inflation
pressure and continue on your trip.
Safety measures in the event of a flat tire:
Park the vehicle as far away from moving
traffic as possible and on a firm surface. Switch
on the hazard warning flashers.
Apply the parking brake and engage first gear
or reverse. Have all occupants leave the vehicle
and move beyond the danger zone, e. g. behind
the guard rails.
If necessary, erect a warning triangle
* or warn-
ing flasher
* at a suitable distance. Adhere to
country-specific regulations.<
Preparations
The M Mobility System is located in the cargo
bay under the floor board.
If possible, leave any foreign bodies that have
penetrated the tire in place.
Instructions on how to use the M Mobility
System can also be found on the device
itself. low the instructions on the sealant bot-
tle.<
Remove the label with the speed restriction
from the sealant bottle and apply it to the steer-
ing wheel.
Please note the expiry date on the sealant
bottle.<

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.<
