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.
WARNING
■
Always read and observe the warnings before completing any work in the
engine compartment » page 274.
■
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.
■
H7 and H8 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.
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
We recommend that a box of replacement bulbs always be carried in the vehi-
cle.
