common reservoir. Open the blue cap to refill washer fluid (see the illustration for the locationof the reservoir). During cold weather, the reservoir should be filled with 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.

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 washingThe following points should be kept in mind when washing and cleaning the vehicle:
CAUTION
Avoid using car washing detergents with a pH value 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 vehicle 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 as
soon as possible. Otherwise the finish maybe permanently damaged.
• A car washing detergent can be used tofacilitate the softening of dirt and oil. •
Dry the vehicle with a clean chamois andremember to clean the drain holes in thedoors and rocker panels.
• Tar spots can be removed with tar removerafter the vehicle 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 spray mouthpiece 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 moonroof cautions:
• Always close the moonroof and sunshade before washing your vehicle.
• Never use abrasive cleaning agents onthe moonroof.
• Never use wax on the rubber sealsaround the moonroof.
NOTE
When washing the vehicle, remember to remove dirt from the drain holes in the doorsand sills.
Automatic car washes
• We do NOT recommend washing your vehi- cle in an automatic wash during the first fewmonths (because the paint will not havehardened sufficiently).
• An automatic wash is a simple and quick wayto clean your vehicle, but it is worth remem-

512bering that it may not be as thorough as when you yourself go over the vehicle withsponge and water. Keeping the underbodyclean is most important, especially in the win-ter. Some automatic washers do not havefacilities for washing the underbody.
NOTE
Condensation may form temporarily on the inside 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.
CAUTION
When using an automatic car wash in which the vehicle has to be able to roll freely, theauto-hold brake function must be deactivated.If this is not done, the brakes will automati-cally be applied when the vehicle is stationary. To deactivate this function:
1. Drive the vehicle into the car wash
2. Turn off the auto-hold function using the
control on the center console
3. Turn off the parking brake's automatic function in the center display's Top view (tap
Settings, tap My CarElectric
Parking Brake and deselect Auto
Activate Parking Brake)
4. Put the gear selector in N
5. Switch off the ignition by turning the start knob to STOP and holding it in this posi-
tion for at least 4 seconds
The vehicle will then be able to roll freely.
CAUTION
• Before driving into an automatic car wash, turn off the optional rain sensor toavoid damaging the windshield wipers.
• Make sure that side view mirrors, auxiliarylamps, etc, are secure, and that anyantenna(s) are retracted or removed. Oth-erwise there is risk of the machine dis-lodging them.
• Chromed wheels:
Clean chrome-plated
wheels using the same detergents usedfor the body of the vehicle. Aggressivewheel-cleaning agents can permanentlystain chrome-plated wheels.
WARNING
• When the vehicle is driven immediately after being washed, apply the brakes,including the parking brake, several timesin order to remove any moisture from thebrake linings.
• Engine cleaning agents should not beused when the engine is warm. This con-stitutes a fire risk.
