Changing a bulb
Procedure for replacing a faulty bulb with a new bulb .
In some climatic conditions (e.g. low temperature or humidity), the presence of misting on the internal surface of the glass of the headlamps and rear lamps is normal; it disappears after the lamps have been on for a few minutes.
The headlamps are fi tted with polycarbonate glass with a protective coating:
- do not clean them using a dry or abrasive cloth, nor with a detergent or solvent product,
- use a sponge and soapy water,
- when using a high pressure washer on persistent marks, do not direct at the lamps or their outlines for too long, so as not to damage their coating and their seals.
Do not touch the bulb directly with your fi ngers, use lintfree cloths.
Changing a halogen bulb should only be done after the headlamp has been switched off for a few minutes (risk of serious burns). It is imperative to use only antiultraviolet (UV) type bulbs in order not to damage the headlamp.
