Individual electrical circuits are protected by fuses. A blown fuse is recognisa-
ble by the molten metal strip » Fig. 356.
WARNINGAlways read and observe the warnings before completing any work in the
engine compartment » page 268.
CAUTION
■
Replace the faulty fuse with a new one of the same amperage.■If a newly inserted fuse blows after a short time, then seek the assistance of
a specialist garage.■
Do “not repair” the fuses and do not replace them with stronger ones - it can
cause a fire and could damage parts of the electrical system.
Note
■ We recommend always carrying replacement fuses in the vehicle.■There can be several power consuming devices for one fuse. Multiple fuses
may exist for a single power consuming device.295Fuses and light bulbs

Bulbs
Introduction
This chapter contains information on the following subjects:

Replacing a bulb for low beam and main beam (halogen headlights)

Bulb for turn signal switch (halogen headlight)

For this reason, 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, high or fog beam.
In the case of failure of a Xenon gas discharge bulb or an LED diode, visit a
specialist garage.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 268.■
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.
■
H7 and H8 bulbs are pressurised and may burst when changing the bulb -
risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the xenon gas discharge lamps - risk of
death!
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.■
The cap of the filament bulb must always be seated correctly in the head-
light, otherwise this may allow water and debris to enter the headlight - risk of
damage to the headlights.
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.
