Refilling coolant
Coolant helps keep the gasoline engine at theproper operating temperature. The heat transfer-red from the engine to the coolant can be usedto warm the passenger compartment.
When refilling coolant, follow the instructions onthe package and use the recommended amountof coolant. Never fill the cooling system withwater only; this could lead to freezing, corrosionand engine damage.

WARNING
If the engine has been running, the coolantwill be very hot. Allow the engine to coolbefore opening the coolant expansion tank. Ifthis is not possible, open the cap very slowlyto allow pressure to dissipate.
Coolant expansion tank
Lift the rubber strip by pressing it inward inthe engine compartment.
Remove the plastic cover by folding out thecatch and lifting the cover upward.
Unscrew the expansion tank cap and addcoolant. The level should be between theMIN and MAX marks on the tank.
Put the other components back in place in thereverse order.
CAUTION
•High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
•Only use coolants with corrosion protec-tion recommended by Volvo.
•The ratio of coolant to water is 50/50.
•Mix the coolant with tap water of drinka-ble quality.
•If maintenance is performed on the cool-ing system or if the coolant is replaced,flush the cooling system with clean waterbefore adding new a new coolant/watermixture.
•The engine may only be operated with aproperly filled cooling system. Otherwise,high temperatures and cracks in the cyl-inders may occur.

During cold weather, the reservoir should be filledwith windshield washer solvent containing anti-freeze. Use Volvo Original Washer Fluid or theequivalent with a recommended pH valuebetween 6 and 8 in a 1:1 solution.
When there is approx. 1 qt (1 liter) of washerfluid remaining in the reservoir, a text message
and the symbol will be displayed in theinstrument panel.

Cleaning the exterior
The vehicle should be washed at regular inter-vals since dirt, dust, insects and tar spotsadhere to the paint and may cause damage. Tohelp prevent corrosion, it is particularly importantto wash the car frequently in the wintertime.

Hand washing
The following points should be kept in mind whenwashing and cleaning the car:

CAUTION
Avoid using car washing detergents with a pHvalue lower than 3.5 or higher than 11.5.Doing so could result in discoloring of ano-dized aluminum surfaces on e.g., roof rails orthe frames around the side windows.
•Avoid washing your car in direct sunlight.Doing so may cause detergents and wax todry out and become abrasive. To avoidscratching, use lukewarm water to soften thedirt before you wash with a soft sponge, andplenty of sudsy water.
•Bird droppings: Remove from paintwork assoon as possible. Otherwise the finish maybe permanently damaged.
•A car washing detergent can be used tofacilitate the softening of dirt and oil.
