partment.
WARNING
Do not repair fuses, and never replace a blown fuse with a higher amper-
age fuse. The electrical system could be damaged, with risk of fire.
CAUTION
● Multiple fuse values on the same line (for example, 5/10/20) in the fol-
lowing tables indicate equipment-related differences. Replace the blown
fuse with a fuse of the same amperage.
● If a newly replaced fuse blows again after a short time, the electrical sys-
tem must be checked by a specialised workshop as soon as possible.
Note
● Positions are not occupied by a fuse do not appear in the following ta-
bles.
● Some of the equipment listed in the tables below pertain only to certain
versions of the model or are an optional extra. Fuses in the vehicle interior

Bulbs
Changing a bulb
Changing bulbs requires a certain degree of practical skill. If you choose to change engine compartment lamps yourself, remember
that it is a dangerous area ⇒ 
in Working on components in the engine
compartment on page 209.
Always use identical bulbs with the same designation. The name can be
found on the base of the bulb holder.
Depending on how equipped the vehicle is, there are different sets of head-
lights and tail lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light* 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. 
