183nLamps and bulbs
The lamps and bulbs make essential
contributions to the safety of your vehi-
cle. For this reason, follow the instruc-
tions below carefully when replacing a
bulb. If you are not familiar with any of
the procedures, consult your BMW
center.
Do not touch the glass portion of a
new bulb with your bare hands
since even small amounts of impurities
burn into 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. <
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer. <
The illustration shows the right-hand
engine compartment.
For checking and adjusting head-
lamp aim, please contact your
BMW center. <

When cleaning the headlamps,
please observe the following:
> Do not wipe dry (scratches). Never
use abrasives or strong
solvents to clean the covers.
Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water.
Always use a deicer spray to remove
accumulated ice and snow – never
use a scraper. <

184nLamps and bulbs
Xenon lamps*
The operating life of these lamp units is
extremely long and the likelihood of fail-
ure very low, provided that they are not
switched on and off a very great num-
ber of times. If one of these bulbs
should nevertheless fail, it is possible to
continue driving with great caution us-
ing the fog lamps, provided traffic laws
in your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
lighting system should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal in-
jury. <
