1Low beams
2High beams
H7 bulb, 55 watts
The H7 bulb is pressurized. Therefore,
wear safety glasses and protective
gloves. Failure to comply with these precau-
tions could result in physical injury if the bulb is
damaged.<
1.Turn the bulb holder to the left and pull out
2.Remove and replace the bulb
3.Install in the reverse order.
When cleaning the headlamps, please
observe the instructions in the Caring for
your vehicle brochure.<
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 continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do not prohibit
this.
Because of the extremely high 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.<

Snap the lamp back into place.
Light-emitting diodes LEDs
Control elements, display units and other inte-
rior equipment in your vehicle use a light-emit-
ting diode behind a cover as a light source.
These light-emitting diodes are similar to con-
ventional lasers.
Do not remove the covers, and do not
look directly at the unfiltered light for sev-
eral hours. Otherwise, it can lead to retinal irrita-
tion of the eye.<
Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss in
inflation pressure.
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Refer to page82.
BMW recommends that you consult your BMW
center if you wish to replace the tires of your
B MW , o r change from summe r to winter tire s o r
vice versa.
Your BMW center knows how to work with Run Flat tires and is equipped with the necessary
special tools.
When mounting or replacing summer
tires with winter tires, or vice versa, use
only Run Flat tires since no spare wheel is avail-
able in the event of a flat.<
Jacking points
The jacking points are located at the positions
indicated in the illustration.
Your BMW center can provide you with a
suitable jack as an accessory.<
Vehicle battery
Maintenance
The battery is completely maintenance-free.
This means that the original electrolyte will nor-
mally last for the service life of the battery under
moderate climatic conditions. Your BMW cen-
ter will be happy to advise you if you have any
questions concerning the battery.
Indicator lamp
The indicator lamp lights up:
The battery is no longer being charged.
The alternator drive belt is defective or
there is a malfunction in the charging circuit of
the alternator. Please contact the nearest BMW
center.
If the drive belt is defective, pull over and
switch off the engine immediately to pre-
vent overheating and serious engine damage.
If the onboard supply voltage drops to a very
low level, increased steering effort may also be
necessary.<

iliary jump-starting terminal of the vehicle to
be jump-started.
Your BMW is equipped with a special nut,
refer also to the engine compartment over-
view on page85
3.With the– jumper cable, connect the nega-
tive terminals of both vehicles.
To do this:
Attach one cable clamp to the negative bat-
tery terminal or to a suitable ground on the
engine or body work of the support vehicle.
Attach the second cable clamp to the nega-
tive battery terminal or to a suitable ground
on the engine or body work of the vehicle to
be jump-started.
Starting the engine
1.Start the engine of the support vehicle and
let it run for several minutes at a slightly ele-
vated engine idle speed
2.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
3.Allow the engines to run for several minutes
4.Then disconnect the jumper cables in
reverse sequence
5.Depending on the cause of the fault, have
the battery checked and recharged.
Never use spray starter fluids to start the
engine.<
Towing and tow-starting the
vehicle
Using the towing eyelet
The screw-in towing eyelet is stored in the
onboard tool kit; be sure that it remains in the
vehicle at all times. It can be attached at the
front or rear of your BMW.
Observe the following instructions in
order to avoid damaging the towing eye-
let or the vehicle: use only the towing eyelet
supplied with the vehicle, and screw it in firmly
until it stops. Use the towing eyelet for towing
on paved roads only. Avoid subjecting the tow-
ing eyelet to lateral loads, e.g. do not lift the
vehicle using the towing eyelet.<
Access to the threaded socket
Press out the cover with a screwdriver inserted
in the recess at the top.
Being towed
Make sure that the ignition key is in posi-
tion 1, because the steering lock could
otherwise engage and the vehicle could no
longer be steered. There is no power assist
while the engine is off. Therefore, you will need
to exert more force to brake and steer the vehi-
cle.<
Turn on the hazard warning flashers, if required
by national regulations. If the electrical system
has failed, clearly identify the vehicle being
towed, e.g. by placing a sign or a warning trian-
gle in the rear window.
Vehicles with manual transmission

Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph /
70 km/h or a towing distance of 90 miles/
150 km. Otherwise, the automatic transmission
could be damaged.<
Vehicles with sequential manual
gearbox SMG
To push or tow the vehicle, turn on the ignition
and move the selector lever to position N, then
turn the ignition off again.
Towing methods
In some countries, it is not permitted to tow the
vehicle with a tow bar or tow rope on public
roads.
Familiarize yourself with the applicable towing
regulations for the country in which you are
driving.
With a tow bar
The towing vehicle must not be lighter
than the vehicle being towed; otherwise,
vehicle handling can no longer be controlled.<
The towing eyelets of both vehicles should be
on the same side. If the tow bar can only be
used in a diagonal position, please note the fol-
lowing:
>Clearance is restricted while you are driving
around corners
>The inclination of the tow bar produces late-
ral force.
Only attach the tow bar to the towing eye-
lets. Other parts of the vehicle could oth-
erwise be damaged.<
With a tow rope
When the towing vehicle is driving off, make
sure that the tow rope is taut.
Use nylon ropes or straps for towing
because they prevent sudden jerking
movements. Attach tow ropes only to the tow-
ing eyelet. Other parts of the vehicle could oth-
erwise be damaged.<
With a tow truck
Have the BMW transported by a tow truck with
a lift sling, or on a flatbed.
Do not lift the vehicle by the towing eye-
let, or by parts of the body or chassis.
Otherwise damage could result.<
Tow-starting
Do not tow-start vehicles with automatic
transmission.
Jump-starting, refer to page97.<
Only tow-start vehicles with catalytic conver-
ters if the engine is cold. It is better to have the
vehicle jump-started, refer to page97.
1.Turn on the hazard warning flashers; com-
ply with national regulations
2.Turn the ignition key to position 2
3.Engage the 3rd gear. For vehicles with
SMG, refer to following column
4.Have the vehicle towed with the clutch
pedal completely depressed and then
slowly release the clutch pedal. After the
engine has started, immediately depress
the clutch pedal again completely
5.Pull over at a suitable location, remove the
tow bar or tow rope, and turn on the hazard
warning flashers
6.Have the vehicle checked.
Vehicles with sequential manual
gearbox SMG
>Have the vehicle towed with the selector
lever in position N
