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.
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.Fuses in the dashboardFig. 185

Introduction
This chapter contains information on the following subjects:
Bulb arrangement in the front headlights
157
Replacing the bulb for the side light (Halogen headlights)
157
Changing the bulb for main beam, separate daytime running lights, and
parking light

Changing the bulb for the front turn signal light

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 warning notes before completing any work
in the engine compartment » page 128.■
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.
156Do-it-yourself
Page 159 of 184

WARNING (Continued)■H7 and H15 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.
