• 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.
