Checking and refilling engine oil The oil level is checked electronically.
Oil filler cap6
It may be necessary to top up engine oil between regularly scheduled services. No action is necessary until a message is dis- played in the instrument panel.
WARNING
If this symbol and Engine oil level
Service required are displayed,
have the vehicle checked by a trained and qualified Volvo service
technician. The oil level may be too high. Do not allow oil to spill onto or come into con- tact with hot exhaust pipe surfaces.
CAUTION
If this symbol and Engine oil level
low Add "....." (an amount of oil) are
displayed, add the amount of oil indicated.
Checking the oil levelThe oil level can be checked in the center display when theengine is not running. From the center display's Home view, swipe the screenfrom right to left to open App
view. Tap
Car status and then tap Status to
show the oil level.
Oil level graphic in the center display
The oil level should be checked at regular inter- vals, particularly during the period up to the firstscheduled maintenance service. If the oil level sensor indicates that the level is too low, using the correct oil, top up with theamount of oil indicated as soon as possible.
NOTE
• The system cannot detect changes in the oil level immediately. The vehicle must bedriven approximately 20 miles (30 km) orhave been parked on level ground withthe engine off for 5 minutes before theoil level reading will be correct.
• If the necessary conditions are not metfor checking the oil level electronically(time interval after the engine wasswitched off, if the vehicle is parked on an incline, etc.),
No values available will
be displayed. This does not indicate a
problem with the oil level sensor.

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.

• 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.
Exterior componentsVolvo recommends the use of special cleaningproducts, available at your Volvo retailer, forcleaning colored plastic, rubber, or ornamental components such as chromed strips on the exte-rior of your vehicle.

* are made of
anodized aluminum and should only be washed with a cleaning product with a pH value between3.5 till 11.5.
