Engine oil
For the recommended service intervals and war-ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
If the engine oil is not checked regularly and thelevel becomes low, this could cause seriousengine damage.

CAUTION
To satisfy the requirements for the engine'sservice intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact.
For the recommended service intervals toapply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected.
Failure to use engine oil of the prescribedgrade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage.
Volvo recommends entrusting oil changes toan authorized Volvo workshop.
Volvo uses different systems to warn if the oillevel is too low/high or the oil pressure is low. Onengine variants with an oil pressure sensor, a
warning symbol is displayed in the instrument
panel when oil pressure is low . On engine
variants with an oil level sensor, the warn-ing symbol in the instrument panel and displaymessages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information.
Change the engine oil and oil filter according tothe schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.

Checking and filling engine oil
The engine oil level is monitored by an electronicoil level sensor.
Filler pipe13.
It may be necessary to top up engine oil betweenregularly scheduled services.
No action is necessary with regard to engine oillevel until a message appears in the instrumentpanel.

WARNING
If this symbol is shown togetherwith the message Engine oil levelService required, visit a workshop– an authorized Volvo workshop isrecommended. The oil level may be too high.
CAUTION
If this symbol is shown togetherwith a message about low oil level,for example Engine oil level lowRefill 1 liter, fill only with the indi-cated volume, e.g. 1 liter (1 quart).

WARNING
Do not spill oil on the hot exhaust pipes asthis could cause a fire.

Viewing oil level in the center display
The oil level can be viewed using the electronicoil level gauge in the center display once thevehicle has been started. The oil level should bechecked regularly.
1.Open the Car Status app from App view inthe center display.
2.Tap Status to display the oil level.
Oil level graphic in the center display.

NOTE
The system cannot directly detect changeswhen the oil is filled or drained. The vehiclemust have been driven approximately 30 km(20 miles) and have been stationary5 minutes on a level surface and with theengine off before the correct oil level will bedisplayed.
13Engines with an electronic oil level sensor do not have a dipstick.

NOTE
If the conditions for measuring oil level arenot properly fulfilled (time after engine shut-down, vehicle inclination, ambient tempera-ture, etc.) the message No value availablewill be shown in the center display. This doesnot mean that anything is wrong in the vehi-cle systems.

Refilling coolant
Coolant helps keep the combustion engine atthe right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions onthe package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant.
If there is coolant under the vehicle, smoke fromthe cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.

WARNING
The coolant may be very hot. Never unscrewthe cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

CAUTION
It is not possible to charge another vehicle'sbattery by means of current through thecharging points. Using the charging points tocharge another vehicle's battery could causea fuse to blow, which would cause the charg-ing points to stop working.

CAUTION
Only a modern battery charger with controlledcharge voltage should be used to charge thestarter battery. The rapid charging functionshould not be used as this could damage thebattery.

NOTE
If both the starter battery and the hybrid bat-tery are discharged, both batteries must becharged. In such cases, it is not possible tocharge only the hybrid battery first.
The starter battery must have a certain levelof charge for it to be possible to charge thehybrid battery.
CAUTION
Failure to observe the following could causethe infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
The negative battery terminal of the vehi-cle's starter battery must never be usedto connect an external starter battery orbattery charger – only the vehicle's neg-ative charging point should be used asa grounding point.
NOTE
If the starter battery becomes discharged toomany times, it will shorten its service life.
The service life of the starter battery is affec-ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity.
To keep the starter battery in a good condi-tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging.
A starter battery that is always kept fullycharged has the maximum service life.
