Replacing components

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. You must be duly diligent
in replacing them. BMW recommends having
your BMW center perform any work that you do
not feel competent to perform yourself or that is
not described here.
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.<
A selection of replacement bulbs is available at
your BMW center.
Only replace bulbs when cool, as other-
wise you may be burned.<
Whenever you perform any work on the
electrical system, turn off the systems/
consumers involved to prevent short circuits
from occurring. To avoid possible injury or
equipment damage when replacing bulbs,
observe any instructions provided by the bulb
manufacturer.<
When caring for the headlamps, please follow
the instructions under Care, starting on
page239.
For bulbs for which changing is not
described, and for checking and adjusting
headlamp aim, please contact your BMW cen-
ter.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Halogen headlamps
The illustration shows the left-hand side of the
engine compartment.
1Cover cap for low beams
2Cover cap for high beams
To remove the cover caps:
>Low beams: press the detent, arrow, and
remove the cover from the guide.
>High beams: turn the cover cap to the left
and remove.
Always wear gloves and eye protection –
the atmosphere within the H7 bulb is
pressurized. Otherwise there is a danger of inju-
ries if the bulb is accidentally damaged during
replacement.<

Preparation
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 assisting vehi-
cle.
3.Switch off any electrical systems and com-
ponents in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
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 in the engine compartment serves as a pos-
itive terminal for the battery, also refer to engine
compartment overview on page233. 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 start-
ing-aid 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 assisting
vehicle.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
Always keep the screw-in tow fitting with the
vehicle. It can be screwed in at the front or rear
of the BMW.
