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. If one of these bulbs should
nevertheless fail, it is possible to continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do not prohibit
this.
Have work on the xenon lighting system
performed only by your BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high voltage involved, there
is a danger to life and limb when work is carried
out improperly.<

Changing wheels
Your BMW is equipped with run-flat tires as a
standard feature. An immediate wheel change
in the event of a flat tire is therefore no longer
required.
To continue driving with a damaged tire:
>With Flat Tire Monitor, refer to Indication of
a flat tire, page90
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure,
page92
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 page214.
If you have new tires mounted or switch from
summer to winter tires, or vice versa, use run-
flat tires because no spare tire is provided in
case of a flat. Your BMW center will be glad to
advise you.
Also refer to New wheels and tires, page214.
The suitable tools for changing tires are
available as accessories from your BMW
center.<
Car jacking points
The jacking points for the car jack are located in
the positions shown.
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate.
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 connections, refer
to Jump starting on page228.
Disposal
After replacement, have old batteries dis-
posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<

Jump starting
When your battery is discharged, you can use
two jumper cables to start your BMW 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. Care-
fully adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible 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 bat-
tery.
2.Switch off the engine of the vehicle provid-
ing assistance.
3.Switch off any electrical systems and com-
ponents in both vehicles.

there is a danger of short circuiting.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables.<
In your BMW, the so-called jump-starting termi-
nal for jump starting in the engine compartment
serves as a positive terminal for the battery, also
refer to engine compartment overview on
page217. The cover cap is marked with a +.
1.Fold open the cover of the BMW jump-
starting 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
jump-starting terminal of the vehicle provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a jump-
starting terminal of the vehicle to be started.
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.
Your BMW has a special nut as body ground
or negative terminal.5.Attach the second end of the cable to the
negative 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 assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2.Start the engine on the other vehicle in the
usual way.
If the first starting attempt is not successful,
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.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page223, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Use the tow fitting for towing only on roads.
Avoid lateral loading of the tow fitting, e.g. do
not lift the vehicle by the tow fitting. Otherwise,
the tow fitting and vehicle can be damaged.<

Being towed
Make sure that the ignition is switched on,
refer to page58; otherwise, the low-beam
headlamps, tail lights, turn signals and wind-
shield wipers would not be available. Do not tow
the vehicle with the rear axle raised, as other-
wise the steering can turn to the left or right.
When the engine is stopped, there is no power
assist. This then requires increased effort for
braking and steering. Active steering is deacti-
vated and larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Sport automatic transmission
Before towing, manually release the
transmission lock, even if there is no mal-
function in the transmission. Otherwise there is
a risk that the transmission lock will automati-
cally be engaged during towing.<
Manually unlocking and locking transmission
lock, refer to page62.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km; otherwise, the sport auto-
matic transmission may be damaged.<
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts; otherwise, damage
may result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed; otherwise, it
will not be possible to reliably control vehicle
response.<
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 offset
angle, please note the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Attach the tow bar to the tow fittings only,
as attachment to other vehicle parts can
lead to damage.<

With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach tow ropes to the tow fittings only, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Tow-starting
Do not tow-start the vehicle if possible, but
instead start the engine by means of jump start-
ing, refer to page228. Vehicles equipped with a
catalytic converter should only be tow-started
when the engine is cold. When equipped with a
sport automatic transmission, the engine can-
not be started by tow-starting.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Switch on the ignition, refer to page58.
3.Shift into 3rd gear.
4.Tow-start with the clutch completely
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch again completely.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
