Individual electrical circuits are protected by fuses. A blown fuse is recognisa-
ble from the melted-through metal strip » Fig. 192.
WARNINGAlways read and observe the warnings before completing any work in the
engine compartment » page 142.
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 -
There is a risk of fire and damage to another 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.167Fuses and light bulbs

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 142.■
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 H7 and H4 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.
■
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.
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.
