Lamps and bulbs  
135  
The lamps and bulbs make essential  
contributions to the safety of your vehi-  
cle. Therefore, comply fully with the fol-  
lowing instructions during bulb replace-  
ment. If you are not familiar with any of  
the procedures, consult your BMW  
center.  
Because of the extremely high  
Low beams and high beams  
voltages involved, any work on the  
xenon lighting system, including bulb-  
changing, should be carried out by  
technically-qualified personnel only.  
Otherwise, there is a risk of fatal  
injury.<  
>Low beams: H7 bulb, 55 watts  
>High beams: H7 bulb, 55 watts  
The H7 bulb is pressurized. There-  
fore, wear safety glasses and pro-  
tective gloves. Failure to comply with  
this precaution could lead to injury if the  
bulb is damaged.<  
Do not touch the glass portion of  
a new bulb with your bare hands  
since even small amounts of impurities  
burn in to the surface and reduce the  
service life of the bulb. Use a clean  
cloth, paper napkin, or a similar mate-  
rial, or hold the bulb by its metallic  
base.<  
Please contact a BMW center in case of  
a malfunction.  
Parking lamps  
5 watt bulb  
Please contact a BMW center in case of  
a malfunction.  
A replacement bulb set is available from  
your BMW center.  
When cleaning the headlamps, please  
follow the instructions in the Caring for  
your vehicle brochure.  
Before working on the electrical  
system, switch off the electrical  
accessory you are working on or dis-  
connect the cable from the negative  
terminal of the battery. Failure to  
observe this precaution could result in  
short circuits.  
To prevent injuries and damage when  
changing a bulb, be sure to comply with  
any instructions provided by the bulb  
manufacturer.<  
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. If one of these bulbs should  
nevertheless fail, it is possible to con-  
tinue driving with great caution using  
the fog lamps, provided traffic laws in  
your area do not prohibit this.

2. Replace the bulb.  
M Mobility system  
You will find an M Mobility system in  
your BMW M3 convertible for repairing  
flat tires. With this system you can  
apply a sealing liquid to the inside of  
the tire that seals off the damaged point  
and then continue driving.  
The M Mobility system makes trans-  
porting a spare wheel superfluous,  
thereby reducing the amount of weight  
you have to carry around.  
140 Repairing a flat tire  
Please keep in mind that the fluids  
bottle in the system's sealant con-  
tainer has to be changed every 3 years  
by your BMW center, if the unit has not  
been used.<  
Preparing the M Mobility system  
for use  
This is part of the M Mobility  
system  
The M Mobility system is located in the

Disconnect the connector hose from  
the sealant container and the wheel  
valve. Stow the M Mobility system in  
the luggage compartment.  
Distributing the sealant  
Right afterward, drive at least  
1 1/4 miles/2 km, so that the liquid  
sealant distributes evenly throughout  
the inside of the tire.  
142 Repairing a flat tire  
Do not exceed a maximum speed  
Even if the tire fails to hold the  
pressure, you should still carry out  
Step 3 before proceeding to drive the  
vehicle again, refer to Distributing the  
sealant for more information. Then  
repeat Steps 1 through 3.  
of 40 mph / 60 km/h. If possible,  
keep the vehicle speed above 10 mph /  
20 km/h.  
Stop in a suitable spot.<  
The use of the M Mobility system may  
be ineffective if the damaged area in  
the tire is larger than approx. 3/16 in /  
4 mm. Please consult the nearest BMW  
center if the tire cannot be temporarily  
repaired with the M Mobility system.<

handling.<  
tion for transport and storage. Secure  
the battery against tilting in transit.<  
Maintenance  
The battery is completely maintenance-  
free. That means that the original bat-  
tery acid will normally last for the ser-  
vice life of the battery under moderate  
climate conditions.  
Protect valve stems against dirt using  
screw-on dust caps. Dirty valve stems  
frequently lead to slow pressure loss.  
Please consult your BMW center  
whenever you have any questions  
concerning the battery. Since the bat-  
tery is absolutely maintenance-free, the  
following statements are for your infor-  
mation only.<  
Never disconnect the battery  
when the engine is running; the  
ensuing voltage surge would seriously  
damage the vehicle's onboard elec-  
tronic systems.<  
Charging the battery  
Charge the battery in the vehicle only  
when the engine is not running. Use the  
connections provided in the engine  
compartment. For information on the  
connections, see Jump-starting,  
page 145.  
144 Fuses  
You will find the fuses and information  
on their respective allocation in the  
glove compartment behind a panel with  
two snap clips.  
Do not attempt to repair a blown  
fuse or replace it with a fuse  
having a different color or amperage  
rating. To do this could cause a fire in  
the vehicle resulting from a circuit over-  
load.<  
Giving and receiving assistance  
Jump-starting  
145  
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 handles on the terminal  
clamps.  
or a suitable ground on the vehicle  
being started. Your BMW is  
equipped with a special nut for this  
purpose – see arrow 2  
Always adhere to this sequence  
when connecting jumper cables;  
failure to observe this procedure can  
lead to sparks at the battery terminals  
and pose an injury hazard.<  
Do not touch high-voltage wiring  
and cables on a running engine.  
Contact with components carrying high  
voltage can be harmful or fatal.  
Carefully observe the following instruc-  
tions to avoid personal injury and/or  
damage to one or both vehicles.<  
6. Start the engine of the support vehi-  
cle and let it run for several minutes  
at a slightly elevated engine idle  
speed  
7. Start the engine of the other vehicle  
as usual. If the first start attempt is  
not successful, wait a few minutes  
before another attempt in order to  
allow the discharged battery to  
recharge  
8. Allow the engines to run for several  
minutes before disconnecting the  
jumper cables  
9. Then disconnect the jumper cables  
in the opposite order.  
4. The auxiliary jump-starting terminal  
located in your BMW's engine com-  
partment acts as the positive battery  
terminal. The cover of this auxiliary  
terminal is marked with a + sign.  
Remove by pulling the tab, see  
arrow 1. Start by connecting the  
jumper cable from the positive termi-  
nal of the discharged battery to the  
positive terminal of the support bat-  
tery  
5. Then connect the negative terminals  
with the other jumper cable. Attach  
the cable to either the support vehi-  
cle's negative battery terminal or to a  
suitable ground on its engine or  
bodywork. Then connect the other  
end to the negative battery terminal  
1. The battery in the support vehicle  
must be rated at 12 volts. This infor-  
mation is provided on the battery  
label  
2. Stop the engine of the support vehi-  
cle and switch off all electrical com-  
ponents in both vehicles – except for  
the hazard warning flashers of the  
support vehicle  
3. Make absolutely certain that there is  
no contact between the bodywork of  
the two vehicles – short circuit haz-  
ard  
Have the battery recharged at your  
BMW center as required.  
Do not use spray starter fluids to  
start the engine.<  
146 Towing the vehicle  
Towing eyelet  
The towing eyelet, which can be  
unscrewed, is in the luggage compart-  
ment under the floor mat and must  
remain in the vehicle. This eyelet is  
designed for installation in the tow  
sockets located at the front and rear of  
the vehicle. It is intended for towing on  
paved road surfaces only.  
The towing eyelet should not be used  
to pull a vehicle out of deep snow, mud,  
sand, etc.  
Access to tow sockets  
Rear:  
Comply with all applicable towing laws  
and regulations at all times.  
Press out the cover panel with a screw-  
driver at the top of the recess.  
Front:  
Press out the cover panel with a screw-  
driver at the top of the recess.  
Make sure the towing eyelet is  
firmly screwed all the way in, oth-  
erwise the thread could be damaged.  
Only use the towing eyelet provided in  
the vehicle to avoid damage.  
Do not tow the vehicle by any compo-  
nents of the running gear, or lash them  
down in any way. If you do, the compo-  
nents could be damaged, possibly  
leading to accidents.<  
Keep the vehicles in line and avoid  
towing at an offset angle. Ensure  
that the tow rope connecting the two  
vehicles is tight, with no slack, before  
starting off.<  
Towing the vehicle  
147  
Use only a nylon towing strap to tow  
the vehicle, since the inherent resil-  
ience of this material helps protect both  
vehicles from sudden jerking move-  
ments.  
5. Switch on the hazard-warning sys-  
tem – observe applicable legal regu-  
lations.  
Find some means of identifying the  
vehicle in tow, for instance, place a sign  
or warning triangle in the rear window.  
The towed vehicle should always  
be the lighter of the two vehicles.  
If this is not the case, it will not be pos-  
sible to control vehicle handling.<  
Make sure that the ignition key  
remains in position 1 even when  
the electrical system has failed to pre-  
vent the steering lock from engaging.  
The steering and brakes are without  
power-assist when the engine is off.  
This means that increased effort is  
required for steering and braking.<  
Tow-starting  
For instructions on jump-starting, refer  
to page 145.  
Towing with a commercial tow  
truck  
Never attempt to use your vehicle to  
push another vehicle, since damage to  
the energy-absorbing bumpers could  
result.
