Replacing components
Onboard tool kit
The onboard tool kit 1, the screw-in tow
fitting 2 and spare fuses and a pair of plas-
tic tweezers 3 are stored in the luggage
compartment. Fold up the cover located
under the floor mat.
Windshield wiper blades
To replace, fold the wiper arm up and hold.
Press the locking lugs together while push-
ing the wiper blade out of the detent toward
the front.
Lamps and bulbs
Lamps and bulbs make an essential contri-
bution to vehicle safety. Therefore, comply
fully with the following instructions during
bulb replacement. If you are not familiar
with the specified procedures, have the
replacements carried out at your BMW
center.Never touch the glass on 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 cloth, napkin etc., or hold the
bulb by its metal socket.<
You can obtain a selection of replacement
bulbs at your BMW center.
When working on the lighting system
you should always switch off the
lights affected to prevent short circuits.
To avoid possible injury or equipment dam-
age when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When performing maintenance on the
headlamps, comply with the instructions in
the separate Caring for your vehicle bro-
chure.
In the case of bulbs where the
replacement is not described, please
consult your BMW center.<
Xenon lamps
The service life of these lamps is very long
and the probability of a failure is very low,
provided that they are not switched on and
off an unusual number of times. In the
unlikely event that one of these lamps
should fail, you can continue driving under
poor visibility conditions by switching on
your fog lamps and proceeding carefully,
where allowed by law.
To avoid the risk of potentially fatal
injuries: owing to the extremely high
voltages at which these units operate, ser-
vice work on the xenon lighting system
should only be carried out by a BMW cen-
ter.<

Light-emitting diodes LEDs
Light-emitting diodes installed behind
translucent lenses serve as the light source
for many of the controls and displays in
your vehicle. These light-emitting diodes,
which operate using a concept similar to
that applied in conventional lasers, are offi-
cially designated as Class 1 light-emitting
diodes.
Do not remove the covers, and never
stare into the unfiltered light several
hours, as irritation of the retina could
result.<
Changing a wheel
Your BMW is equipped with run-flat tires as
standard. An immediate wheel change in
the event of a flat tire is therefore no longer
required.
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to Run-flat tires on
page 167.
If you switch from summer to winter tires,
or vice versa, use only run-flat tires, as in
the event of a flat there is no spare tire
available. Your BMW center will be glad to
advise you.
Also refer to New wheels and tires,
page 168.
Car jacking points
The jacking points for the car jack are
located in the positions shown.
You can obtain a suitable car jack as
an accessory at your BMW center.<
Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
Your BMW center will be glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine switched off. For the con-
nections, refer to Jump-starting on
page 184.
Disposal
Have old batteries disposed of by
your BMW center or hand them in to a
recycling center. Maintain the battery in an
upright position for transport and storage.
Always restrain the battery to prevent it
from tipping over during transport.<
Power cut
After a temporary power cut, e.g. with a
discharged battery, the features of some
equipment are limited and it has to be rein-
itialized. Individual settings are also lost
and have to be updated:
