Replacing components
Onboard tool kit
The onboard tool kit is located in the lug-
gage compartment lid.
Loosen the wingnut to open.
Windshield wiper blades
To replace, fold the wiper arm up and hold.
Press the catches together while pushing
the wiper blade out of the front.
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, have the replacements carried out at
your BMW center.
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 cloth, napkin, etc., or hold the
bulb by its metal socket.
In the case of bulbs where the replacement
is not described, please consult your BMW
center.<
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.<
Headlamps
The illustration shows the left-hand side of
the engine compartment.
1Cover cap for low beams
2Cover cap for high beams
Turn the cover cap to the left and remove.
Always wear gloves and eye protec-
tion Ð the atmosphere within the H7
bulb is pressurized. Failure to observe this
precaution can lead to personal injury
should the bulb be damaged.<

Replacing components
188 3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that
the entire surface of the jack's base is in
firm contact with the ground and that
the jack itself is standing completely
vertical, not tilted, and that the fitting on
the top of the jack will align with the
rectangular recess on the vehicle when
you raise it, refer to illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the
wheel and hub. Clean the lug bolts
8.Position the new wheel or compact
wheel. Secure the wheel by turning at
least two lug bolts into opposite bolt
holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
10.Lower the jack and remove it from
beneath the vehicle
11.Tighten the lug bolts in a diagonal pat-
tern
12.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
After mounting the wheel or correcting the
inflation pressure, reinitialize the Flat Tire
Monitor, refer to page 81.The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.
To ensure safety, always have the lug bolts
checked with a calibrated torque wrench
as soon as possible to ensure that they are
tightened to the specified torque.
The tightening torque is 120 Nm.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h.
The driving characteristics change, for
example reduced track stability on braking,
extended braking distance, and altered
self-steering characteristics in the limit
range. In conjunction with winter tires,
these characteristics are more pro-
nounced.
Only one compact wheel may be
mounted. You should fit wheels and
tires of the original size as quickly as possi-
ble.<
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.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<

Charging the 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 page 192.
Disposal
Return used batteries to a recycling
point or your BMW center. Maintain
the battery in an upright position for trans-
port and storage. Always restrain the bat-
tery to prevent it from tipping over during
transport.<
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, plastic tweezers and details of
the fuse assignment are located in the
compartment for the onboard tool kit, refer
to page 184.
In the glove compartment
Turn the two snap fasteners outwards. Fold
the cover forwards or remove.
In the luggage compartment
Raise the floor mat and the cover beneath
it. Undo the screw connection of the right
side panel and pull out the panel.

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 clamp
handles.
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 injuries.<
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 consumer units in both
vehicles.
There must not be any contact
between the bodies of the two vehi-
cles, as otherwise there is a danger of short
circuits.<
Connecting the jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
On your BMW, the so-called starting-aid
terminal in the engine compartment serves
as the battery positive terminal, refer also
to Engine compartment overview on
page 178. The symbol + is embossed on
the cover.
1.Open the cover of the BMW starting-aid
terminal. To do so, pull the tab
2.Attach one end of the jumper cable
plus/+ to the positive terminal of the
battery or a starting-aid terminal of the
vehicle providing assistance
3.Attach the second end of the cable to
the positive terminal of the battery or to
a starting-aid terminal of the vehicle to
be started
Your BMW has a special nut as body
ground or negative pole.
4.Attach one end of the jumper cable
minus/Ð to the negative terminal of the
battery or to an engine or body ground
of the vehicle providing assistance

5.Attach the second end of the cable to
the negative terminal of the battery or to
the engine or body ground of the vehi-
cle to be started.
Starting the 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.Let the engines run for a few 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
Always observe all applicable towing
laws and regulations.<
Towing with a commercial tow truck
>Use a wheel lift or flatbed carrier
>Do not tow with sling-type equipment.
Never allow passengers to ride on a
towed vehicle for any reason.<
Towing with raised front axle
Vehicles with automatic
transmission:
1.Towing speed:
Maximum 45 mph/70 km/h
2.Towing distance:
Maximum of 90 miles/150 km.
Vehicles with Sequential manual
transmission SMG
With the ignition switched on, engage the
selector lever position N, then switch off
the ignition again.
Tow fitting
The threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment lid, refer to page 184, and
should always remain in the vehicle. It can
be screwed to the front or rear of the vehi-
cle.
