Introduction to the topic
Bef
ore changing a bulb, check whether a bulb
or LED light unit has failed. You can normally
change bulbs yourself. If the exterior lighting
is realised using LED technology, depending
on model and vehicle equipment, it is not
possible for you to change the LED light units
or individual LEDs yourself. If individual LEDs
fail, this may be an indication that more LEDs
are on the point of failure. In this case, have
the LED light units checked and renewed if
necessary at a qualified workshop.
It may be illegal to drive with faulty exterior
lights.
Additional bulb specifications
Some bulbs might have factory specifications
that differ from standard bulbs. The designa-
tion is inscribed on the bulb, either on the
glass part or on the base. NOTICE
Damage to the electrical system can be
caused by water entering the system if the
rubber co
ver or plastic covers on the head-
light housing are not properly mounted after
a bulb has been changed. Checklist “Information on
changing bulbs”
