•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.
WARNING
• The ignition should be switched off com- pletely (be in ignition mode
0) when
replacing bulbs.
• If the engine has been running just prior to replacing bulbs in the headlight hous-ing, please keep in mind that componentsin the engine compartment will be hot.
