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.

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.

•Dry the car with a clean chamois andremember to clean the drain holes in thedoors and rocker panels.
•Tar spots can be removed with tar removerafter the car has been washed.
•A stiff-bristle brush and lukewarm soapywater can be used to clean the wiper blades.Frequent cleaning of the windshield andwiper blades improves visibility considerablyand also helps prolong the service life of thewiper blades.
•Wash off the dirt from the underside (wheelhousings, fenders, etc).
•In areas of high industrial fallout, more fre-quent washing is recommended.

CAUTION
•During high pressure washing, the spraymouthpiece must never be closer to thevehicle than 13" (30 cm). Do not sprayinto the locks.
•Dirt, snow, etc., on the headlights canreduce lighting capacity considerably.Clean the headlights regularly, for exam-ple when refueling.
Special laminated panoramic roof cau-tions:
•Always close the laminated panoramicroof and sun shade before washing yourvehicle.
•Never use abrasive cleaning agents onthe laminated panoramic roof.
•Never use wax on the rubber sealsaround the laminated panoramic roof.

NOTE
When washing the car, remember to removedirt from the drain holes in the doors and sills.

Automatic car washes
•We do NOT recommend washing your car inan automatic wash during the first few
months (because the paint will not havehardened sufficiently).
•An automatic wash is a simple and quick wayto clean your car, but it is worth rememberingthat it may not be as thorough as when youyourself go over the car with sponge andwater. Keeping the underbody clean is mostimportant, especially in the winter. Someautomatic washers do not have facilities forwashing the underbody.
NOTE
Condensation may form temporarily on theinside of the lenses of exterior lights such asheadlights or taillights. This is normal and thelights are designed to withstand moisture.Normally, condensation will dissipate after thelights have been on for a short time.
