Bulbs
Introduction
This Owner's Manual only describes the replacement of bulbs where it is possi-
ble to replace the bulbs on your own without any complications arising. Other
bulbs or LED lights must be replaced by a specialist garage.
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.
WARNING
■
Always read and observe the warnings before completing any work in the
engine compartment » page 209.
■
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 difficulty
by other road users.
■
Bulbs H8, 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.
