Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should not exceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in the reverse order.
CAUTION
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
• Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
• High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

CAUTION
Never touch the bulb glass with your bare fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which may damage it.
NOTE
If the error message persists after the defec- tive bulb has been replaced, we recommend avisit to an authorized Volvo workshop.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.
