Individual electrical circuits are protected by fuses. A blown fuse is recognisa-
ble from the melted-through metal strip » Fig. 164.
WARNINGAlways read and observe the warnings before completing any work in the
engine compartment » page 120.
CAUTION
■
Replace the faulty fuse with a new one of the same amperage.■If a newly inserted fuse again blows after a short time, then seek assistance
from a specialist garage.■
“Do not repair” the fuses and do not replace them with stronger fuses - dan-
ger of fire and damage to another electrical system.

We recommend having bulbs replaced by a specialist garage or seeking other
expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low or high beam unit or the fog lamp.
Visit a specialist garage if an LED diode is faulty.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 120.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H4, HB4 and H7 are pressurised and may burst when changed –
There is a risk of injury! We therefore recommended wearing gloves and
safety glasses when changing a bulb.
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle.
