Replacing bulbs

Important safety notes

../../../../global/pictures_mb/symb_achtung.png

DANGER

Xenon bulbs are under high voltage. You can get an electric shock if you remove the cover of the xenon bulb and touch the electrical contacts. There is a risk of fatal injury.

Never touch the parts or the electrical contacts of the xenon bulb. Always have work on the xenon bulbs carried out at a qualified specialist workshop.

WARNING

Bulbs, lamps and plug connectors can become very hot during use. When replacing a bulb, you could burn yourself on these components. There is a risk of injury.

Allow these components to cool down before replacing the bulb.

Make sure bulbs are positioned securely.

If your vehicle is equipped with bi-xenon bulbs, you can recognise this by the following: the cone of light from the xenon bulbs moves from the top to the bottom and back again when you start the engine. For this to be observed, the dipped-beam headlamps must be switched on before starting the engine.

Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly.

  • Always switch off the ignition before replacing bulbs in the lighting system. This will prevent a short circuit.

  • Wear gloves and eye protection when changing a bulb.

  • Do not use a bulb that has been dropped or that has scratches on its glass tube. The bulb could may explode.

  • A bulb could explode if:

    • you touch it

    • it is hot

    • you drop it

    • you scratch or score it

  • Marks on the glass tube shorten the operating life of a bulb. Do not touch the glass tube with your bare hands. If necessary, clean the glass tube when cold with alcohol or spirit. Then rub off the glass tube with a clean, lint-free cloth.

  • Make sure that bulbs are protected from moisture when operating and that they do not come into contact with liquids. Make sure that seals are seated correctly and replace damaged seals.

  • Check the contacts for signs of corrosion and clean these if required.

  • Only operate bulbs in closed lamps which have been designed for this purpose.

  • Only use spare bulbs of the same type, with the prescribed voltage and the correct wattage.

  • If the new bulb does not light up, consult a qualified specialist workshop.

  • Have the LEDs and bulbs of the following lamps replaced at a qualified specialist workshop:

    • the third brake lamp

    • the bi-xenon bulbs

    • rear interior lights with reading lamps in the grab handles

If you require assistance changing bulbs, consult a qualified specialist workshop.

The LEDs in the daytime driving lights cannot be changed. Have the headlamp replaced at a qualified specialist workshop.
