WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● When changing bulbs, please take care not to injure yourself on sharp
edges, in particular on the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. Other-
wise, a short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
● Take good care to avoid damaging any components.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface. 
