Xenon headlamps
Xenon headlamps
Because of the long life of these bulbs, the like‐
lihood of failure is very low. Switching the lamps
on and off frequently shortens their life.
If a xenon bulb fails, switch on the front fog lamps
and continue the trip with great care. Comply
with local regulations.
Do not perform work/bulb replacement on
xenon headlamps
Have any work on the xenon lighting system, in‐
cluding bulb replacement, performed only by a
service center. Due to the high voltage present
in the system, there is the danger of fatal injuries
if work is carried out improperly.◀
