Some manual skills are required to change a bulb. For this reason, we recom-
mend having bulbs replaced by a specialist garage or seeking other expert help
in the event of any uncertainties.
▶
Switch off the ignition and the relevant 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.
A stowage compartment for replacement bulbs is located in a plastic box in
the spare wheel or underneath the floor covering in the luggage compartment.
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the low, high or fog beam.
In case of failure of a xenon gas discharge lamp or an LED diode, visit a special-
ist garage.
WARNING
■
Always read and observe the warnings before completing any work in the
engine compartment » page 194.
■
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 H8 and H15 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.
