Lamps

Lamps
Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle lighting
is switched on. You can use the parking
lamps to signal the position of the vehi-
cle when it is parked. For information on lighting
on one side of the vehicle for parking, which is
available as an additional feature, refer to
page57.
Low beams
When you switch off the ignition with
the low beam headlamps on, only the
parking lamps will remain on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page91.
Follow me home lamps
When you activate the headlamp flasher after
parking the vehicle and switching off the lights,
the low beams will come on for a brief period.
You can also have this function activated/
deactivated if you wish.<
LIGHTS ON warning
Whenever you open the driver's door after hav-
ing turned the ignition key to position 0, you will
hear an acoustic signal for a few seconds to remind you that the lamps have not been
switched off.
Daytime driving lamps*
If you desire, the light switch can be left in the
second position:
When the ignition is switched off, the external
lighting is also switched off.
You can have the activation settings for
the daytime driving lamps programmed
on your vehicle.<
Automatic headlamp control*
When the switch is set to this position,
the system automatically activates and
cancels the low beams in response to
changes in ambient light, for example in tun-
nels, at dusk, and when it is raining or snowing.
The low-beam headlamps remain on
regardless of the ambient light when you
switch on the fog lamps.<
Automatic headlamp control cannot
serve as a substitute for the driver's jud-
gement in determining when the vehicle lights
should be switched on. For example, the sen-
sors are not able to detect fog. To avoid safety
risks, you should respond to these kinds of low-
visibility situations by switching the headlamps
on manually.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<

Lamps and bulbs
The lamps and bulbs make essential contribu-
tions to the safety of your vehicle. Therefore,
comply fully with the following instructions dur-
ing bulb replacement. If you are not familiar with
the procedures, BMW recommends that you
have your BMW center carry out the work.
Do not touch the glass portion of a new
bulb with your bare hands since even
small amounts of impurities burn in to the sur-
face and reduce the service life of the bulb. Use
a clean cloth, paper napkin or a similar material,
or hold the bulb by its metallic base.<
A replacement bulb set is available from your
BMW center.
Before working on the electrical system,
switch off the electrical accessory you are
working on or disconnect the cable from the
negative terminal of the battery. Failure to
observe this precaution could result in short cir-
cuits.
To prevent injuries and damage, always comply
with any instructions provided by the bulb man-
ufacturer.<
Accessing the headlamps
Protective cover in the wheel well
To gain access to the headlamp covers, turn the
front wheels in the required direction.

Replacement procedures
92 1.Open the caps with a suitable object, e.g. a
coin or screwdriver
2.Fold up the protective cover in the wheel
well.
Headlamp cover
1.Pull the wire clamp out straight
2.Pull the wire clamp past the catches, see
arrows, and fold it down
3.Flip the headlamp cover open and remove.

Low beams and high beams
Left side of engine compartment:
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.<

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.<
