Replacing bulbs
The halogen headlight bulbs can be replaced by the owner.
Before the bulbs can be replaced, that plastic covering over the headlight housing has to beremoved.
To do so:
Lift the rubber strip by pressing in toward the engine compartment.
Release the pins in the plastic covering's four clips by pressing them down with ascrewdriver or similar object and remove thecovering.
The turn signal, high/low beam, Daytime RunningLight and parking light bulbs will be accessiblewhen the plastic covering has been removed. Put the covering back in place in the reverse order.
NOTE
The pins in the clips have to be pressed back completely before the clips are placed in theplastic covering. When the covering is put back in place, the pins must be pressed so that their upper sur-face is flush with the surface of the clip.
NOTE
• For information regarding any bulbs not mentioned in this section, please contactyour Volvo retailer or a trained andauthorized Volvo service technician.
• Always switch off the ignition before star-ting to replace a bulb.
• If an error message remains in the dis-play after a faulty bulb has been replaced,contact an authorized Volvo workshop.
• Condensation may form temporarily onthe inside of the lenses of exterior lightssuch as headlights, fog lights, or taillights.This is normal and the lights aredesigned to withstand moisture. Normally,condensation will dissipate after thelights have been on for a short time.
• The optional Active Bending Light bulbscontain trace amounts of mercury. Thesebulbs should always be disposed of by atrained and qualified Volvo service techni-cian.
CAUTION
Never touch the glass of bulbs with your fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which will damage it.
