Exterior lighting
Introduction to the topic
Before 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.
WARNING
Changing bulbs incorrectly can cause acci-
dents and serious injuries.
·
When working in the bonnet space, al-
ways read and observe the safety warn-
ings → page 309. The bonnet space of
any vehicle is a dangerous area. Serious
injuries can be sustained here.
·
Halogen bulbs are pressurised and could
explode when they are being changed.
·
Change the defective bulb only once it
has cooled down completely.
·
Never change a bulb unless you are fa-
miliar with the procedure. If you are un-
certain of what to do, the work should
be carried out by a qualified workshop.
·
Do not touch the glass part of the bulb
with unprotected fingers. When the light
is switched on, heat will cause finger-
prints to evaporate on the bulb, which in
turn will cause the reflector to “go blind”
·
There are sharp-edged parts on the
headlight housing and on the tail light
cluster housing. Protect your hands
when changing bulbs.
NOTICE
Damage to the electrical system can be
caused by water entering the system if the
rubber cover or plastic covers on the head-
light housing are not properly mounted after
a bulb has been changed.
