Engine compartment overview
This overview shows some service-related com-ponents.
Some of the components included in the vehi-cle's electric drive system are located in theengine compartment. Exercise caution whenaccessing the engine compartment and onlytouch what is required for normal maintenance.

WARNING
Orange wiring may only be handled by quali-fied personnel.

WARNING
Several components in the vehicle work withhigh voltage that can be hazardous in case ofan incorrect procedure.
Do not touch anything that is not clearlydescribed in this Owner's Manual.
Be careful when checking/filling fluids inthe engine compartment.
The layout of the engine compartment may vary depend-ing on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driver'sside)
Washer fluid filler pipe12
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located atthe front of the engine compartment behindthe radiator) may start or continue runningautomatically up to about 6 minutes after theengine is turned off.
Always entrust engine washing to a workshop– an authorized Volvo workshop is recom-mended. If the engine is hot, there is a risk offire.

WARNING
The ignition system works with extremely highand dangerous voltages. The vehicle electricalsystem should always be in ignition mode 0when work in being performed in the enginecompartment.
Do not touch any spark plugs or ignition coilswhen the vehicle electrical system is in igni-tion mode II or when the engine is warm.

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.

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.

The start battery is used to start the electricalsystem and power electrical equipment in thevehicle. The hybrid battery is used to start thecombustion engine.
The start battery should only be replaced by a
workshop15.
The start battery is a 12 V AGM (Absorbed GlassMat) battery, dimensioned for regenerative charg-ing and to support the function of the vehicle'svarious systems.
The service life and performance of the start bat-tery are affected by factors such as driving style,driving conditions, climate, battery discharges,number of starts, etc.
Never disconnect the start battery while theengine is running.
Make sure the cables to the start battery arecorrectly connected and the clamps aresecurely tightened.

WARNING
Batteries generate hydrogen gas, whichis flammable and explosive.
Do not connect the jumper cable to anypart of the fuel system or to any movingparts. Avoid touching hot manifolds.
Battery fluid contains sulfuric acid. Do notallow battery fluid to contact eyes, skin,fabrics or painted surfaces.
If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.
