Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.

Replacing bulbs
Bulb types vary depending on model and equipment level. If a light bulb 15
breaks, it can
be replaced by following the procedure shown in the Owner's Manual. If you are experiencing problems with any lights other than light bulbs, contact a work- shop 16
.
If there is a problem with an LED 17
light, the
entire lamp unit will normally need to be replaced.

WARNING
The vehicle electrical system must be in ignition mode 0 when bulbs are replaced.

Never touch the bulb glass with your bare fingers. Grease and oils from your fingersvaporize in the heat and will leave adeposit on the reflector, which may dam-age it.
NOTE
If the error message persists after the defective bulb has been replaced, we rec-ommend a visit to an authorized Volvoworkshop.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.

traces of mercury and should therefore always be submitted to a certified Volvoservice technician.
