system - risk of fire!
© CAUTION
If a newly replaced fuse blows again after a
short time, the electrical system must be
checked by a qualified workshop as soon as
possible.

General notes
Changing bulbs requires a certain degree of
practical
skill.

LED*
lights are maintenance-free and cannot be

changed.
For repairs, please contact a qualified
workshop.
If
you
decide to change bulbs in the engine com­
partment yourself, be aware of the safety risks
involved
*
A in Working on components in the
engine compartment on page 295.
WARNING
- Take particular care when working on com­
ponents in the engine compartment if the
engine is warm - risk of burns!
- Bulbs are sensitive to pressure. The glass
can break when you touch the bulb, causing
injury.
- When changing bulbs, please take care not
to injure yourself on sharp edges, in particu­
lar on the headlight housing.
© CAUTION
-Always switch off the ignition before carry­
ing out any work on the electrical system -
danger of short circuiting!
- Switch off the Lights or parking lights before
you change a bulb.
- Take good care to avoid damaging any com­
ponents.
