WARNING
•
Take particular care when working on components in the
engine compartment if the engine is warm - risk of burns!
•
Bulbs are sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
•
Incorrect handling of the high-voltage element of xenon gas-
discharge bulbs* can have potentially fatal consequences.
•
When changing bulbs, please take care not to injure yourself on
sharp edges, in particular on the headlight housing.Caution
•
Always remove the ignition key before carrying out any work on
the electrical system - danger of short circuiting!
•
Switch off the lights or parking lights before you change a bulb.
•
Take good care to avoid damaging any components.
•
Removing the lights in particular can lead to the paintwork
becoming damaged. This is another reason why we recommend
having the bulbs changed by a qualified workshop.For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in
the proper manner.
Note
Place the parts you have removed on a soft cloth so that they do not
become scratched.•
Please check at regular intervals that all lighting (especially the
exterior lighting) on your vehicle is functioning properly. This is not
only in the interest of your own safety, but also in 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 vaporise as a result of the heat generated by the bulb,
be deposited on the reflector and impair its surface.
Bulbs with a bayonet fastenerBulbs with a bayonet fastener must be changed as follows:
Removing the bulb
– Lightly press the defective bulb into the bulb holder, then
turn it anti-clockwise and remove it.
– Do not touch the glass part of the new bulb with your
bare hands, use a cloth or paper towel instead.
Fitting the bulb
– Fit the new bulb, pressing it into the bulb holder, and turn
it clockwise as far as it will go.
– If necessary, use a cloth to remove any fingerprints from
the glass part of the bulb.
