Lamps and bulbs
The lamps and bulbs are essential factors
contributing to the safety of your vehicle.
Therefore, comply fully with the following
instructions during bulb replacement. If you
are not familiar with the specified proce-
dures, BMW recommends having the
replacements carried out at your BMW
center.
Never touch the glass of new bulbs
w i t h y o u r b a r e f i n g e r s , a s e v e n m i n u t e
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. To prevent short circuits, before
working on any electrical system,
equipment or accessory you should always
switch it off and disconnect the cable from
the battery's negative terminal before start-
ing.
To avoid possible injury or equipment dam-
age when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When maintaining the headlamps,
please comply with the instructions in
the separate Caring for your vehicle bro-
chure.<

3.Remove and replace the bulb.
Xenon lamps
The service life of these bulbs 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 respond by switching
on your fog lamps and proceeding care-
fully, where allowed by law. Only have work on the xenon lighting
system including bulb changes car-
ried out by a BMW center or a workshop
that uses personnel trained in accordance
with BMW requirements. Due to the high
voltage involved, there is a danger to life
and limb when work is carried out improp-
erly.<
Parking and standing lamps
In the event of a malfunction, please con-
tact your BMW center.

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 for sev-
eral hours, as irritation of the iris could
result.<
Changing wheels
Safety precautions to observe in the
event of a flat and during all tire
changes:
Park the vehicle as far as possible from
passing traffic. Park on a firm, flat, surface.
Switch on the hazard warning flashers.
Engage the parking brake and move the
transmission's selector lever to P.
Have all vehicle occupants get out of the
vehicle and ensure that they remain outside
the immediate area in a safe place, such as
behind a guardrail.
If a warning triangle or portable hazard
warning lamp is required, set it up on the
roadside at an appropriate distance from
the rear of the vehicle. Comply with all
safety guidelines and regulations.
Change the wheel only on a level, firm sur-
face which is not slippery. The vehicle or
the jack could slip to the side if you attempt
to raise the vehicle on a soft or slippery sur-
face such as snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-
carrying capacity.
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
What you will need
To avoid rattling noises, note the positions
of the tools before removing them, then
return them to their initial positions after
completing work.
>Lug wrench

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
happy to advise you on all questions con-
cerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page210.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked. A mes-
sage appears in the Check Control. Please
take note of the supplementary information
provided on the Control Display.
Disposal
Have old batteries disposed of follow-
ing replacement at your BMW center
or bring them to a collection point. Maintain
the battery in an upright position for trans-
port and storage. Always secure the battery
to prevent it from tipping over during trans-
port.<
Power failure
Following a temporary power failure, e.g. in
the case of a flat battery, some equipment
is subject to restricted use and must be
reinitialized. Individual settings are also lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again,
refer to page55
>Time and date
Must be updated again, refer to
page90
>Radio
Stations must be stored again, refer to
page 154
>Navigation system
The operability must be waited for, refer
to page130.
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In glove compartment
Press the tab on the cover to the front, then
fold up the cover.

Giving and receiving assistance
Warning triangle*
The warning triangle is conveniently stored
in the onboard tool kit mounted on the
inside of the luggage compartment lid.
Comply with legal requirements
requiring you to carry a hazard warn-
ing triangle in the vehicle.<
First-aid kit*
You will also find the first-aid kit in the
onboard tool kit's container.
Some of the articles contained in the
first-aid kit have a limited service life.
Therefore, check the expiration dates of the
contents regularly and replace the contents
concerned in good time if necessary. You
can find replacements in any pharmacy.
Comply with legal requirements requiring
you to carry a first-aid kit in the vehicle.<
Jump-starting
When your battery is discharged you can
use two jumper cables to start your vehicle
with power from the battery in a second
vehicle. You can also use the same method
to help start another vehicle. Use only
jumper cables with fully-insulated terminal
clamps.
To avoid the risk of potentially fatal
injury, always avoid all contact with
electrical components while the engine is running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible personal injury.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance
in Ah. This information can be found on
the battery
2.Switch off the engine of the support
vehicle
3.Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits.<
Connecting jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting. It is located within the engine
compartment, refer to arrow 1 in the illus-
tration. The symbol + is embossed on the
cover.
1.Remove the cover of the BMW auxiliary
terminal for jump-starting
2.Connect one terminal clamp of the pos-
itive/+ jumper cable to the positive ter-
minal of the battery or an auxiliary termi-

providing starting assistance
3.Connect the second terminal clamp of
the positive/+ jumper cable to the posi-
tive terminal of the battery or to an aux-
iliary terminal for jump-starting of the
vehicle to be started
On your BMW, there is a special nut as
body ground on the suspension strut
dome, refer to arrow2 in the illustration.
4.Attach one end of the jumper cable
minus/– to the negative terminal of the
battery or to an engine or body ground
of the vehicle providing assistance
5.Connect the second terminal clamp of
the negative/– jumper cable to the neg-
ative terminal of the battery or to the
engine or body ground of the vehicle to
be started.
Starting engine
1.Start the engine on the support vehicle
and allow it to run for several minutes at
a fast idle
2.Start the engine on the other vehicle in
the usual way.
If the first start attempt is not success-
ful, wait a few minutes before another
attempt in order to allow the discharged
battery to recharge
3.Allow the engines to run for several
minutes
4.Disconnect the jumper cables by
reversing the connection sequence.
If required, have the battery inspected and
recharged at your BMW center.
Never use spray fluids to start the
engine.<
Towing
Using tow fitting
The threaded tow fitting is stored in the
onboard tool kit and must always remain in
the vehicle. It can be screwed in at the front
or rear of the BMW.
To avoid damage to the tow fitting
and the vehicle, observe the follow-
ing: only use the tow fitting that comes with
the vehicle and screw it in as far as it will
go. Only use the tow fitting to tow on roads.
Avoid lateral loading of the tow fitting, e.g.
do not lift the vehicle by the tow fitting.<
Access to screw thread
Press the arrow symbol to push out the
cover.
Being towed
Do not tow the vehicle by the rear
axle; because the steering detent is
not operational, the wheels could turn to an
extreme angle during towing. There is no
power assist with the engine stopped. This
then requires increased effort for braking
and steering.<
Switch on the hazard warning flashers
depending on the local regulations. If the
electrical system fails, mark the vehicle to
be towed, e.g. with a sign or warning trian-
gle in the rear window.
