Replacing components
Mobility
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer. <
For care of the headla mps, please follow the
instructions in the ch apter entitled 'Care'.
To replace lamps not described here,
please contact your BMW center. <
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls, displays, and equipment 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 or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation of the retina. <
Headlight lenses
In cool or humid weather, condensation may
form on the interior of outside lamps. The con-
densation will disappear after a short time when
driving with the headlamps switched on. The
headlamp glasses do not need to be changed.
If the headlamps do not defrost despite driving
with the headlamps switch ed on, and additional
moisture builds up, for example water droplets
in the lamps, have them checked by your BMW
center.
Xenon lamps
These bulbs have a very lo ng service life and are
highly unlikely to fail. If a xenon lamp fails never-
theless, switch on the fog lamps and continue
the journey with great ca re, provided that local
legislation does not prohibit this. Have all work on the xenon lamp system,
including bulb replacements, performed
only by your BMW center . Due to high voltage,
there is a risk of fatal injury if work on the xenon
lamps is carried out improperly. <
Access to the lamps
1.Switch off the lamps and take the remote
control out of the ignition lock.
2. Remove the upper co ver from the head-
lamp. To do so, use a screwdriver to press
the catches towards th e rear, see arrows,
and pull the cover forward and out.
Follow the same steps in reverse order to reat-
tach the cover. Be careful when inst alling the cover; oth-
erwise, leaks could occur and cause dam-
age to the headlamp system.<
