Fuses and bulbs Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 251
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
● One single consumer could have more than one fuse.
● Several consumers could run over one single fuse. 

294Fuses and bulbs
Full-LED headlight system*
Full-LED headlights handle all light functions (daylight, side light, turn sig-
nal, dipped beam and route light) with light emitting diodes (LEDs) as a
light source.
Full-LED headlights are designed to last the lifetime of the car and light
bulbs cannot be replaced. In case of headlight failure, go to an authorised
workshop to have it replaced.

WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm. Risk of burns.
● Bulbs are highly 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 particular on the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. Other-
wise, a short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
● Take good care to avoid damaging any components.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface. 
