2010.5 Citroen DS4 Owner's Manual

Changing a bulb
The headlamps are fitted with polycarbonate glass with a protective coating:  do not clean them using a dr y 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 protective coating and seals.
 Do not touch the bulb directly with your fingers, use lint-free cloths. Changing a 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 anti-ultraviolet (UV) type bulbs in order not to damage the headlamp. Always replace a failed bulb with a new bulb with the same type and specification.
