The entire headlight housing must be lifted out when replacing all front bulbs (except for the fog lights). CAUTION Never touch the glass of bulbs with your fingers. Grease and oils from your fingers vaporize in the heat and will leave a deposit on the reflector, which will damage it. NOTE Always switch off the ignition before starting to replace a bulb. The optional Bi-Xenon® headlight bulbs contain trace amounts of mercury. These bulbs should always be disposed of by a trained and qualified Volvo service technician.
