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.
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.
