Engine compartment overview
This overview shows some service-related components.
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 mainte-nance.
WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly.
Do not touch anything that is not clearly described in this Owner's Man-ual.
Be careful when checking/filling fluidsin the engine compartment.
The layout of the engine compartment may vary depending on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driv- er's side)
Washer fluid filler pipe 12
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartmentbehind the radiator) may start or continuerunning automatically up to about6 minutes after the engine is turned off. Always entrust engine washing to a work- shop – an authorized Volvo workshop isrecommended. If the engine is hot, there isa risk of fire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicleelectrical system should always be in igni-tion mode
0 when work in being per-
formed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system isin ignition mode II or when the engine is
warm.

Open the
Car Status app from App view
in the center display.
2. Tap
Status to display the oil level.
Oil level graphic in the center display.
NOTE
The system cannot directly detect changes when the oil is filled or drained. The vehiclemust have been driven approximately30 km (20 miles) and have been stationary5 minutes on a level surface and with theengine off before the correct oil level willbe displayed.
NOTE
If the conditions for measuring oil level are not properly fulfilled (time after engineshutdown, vehicle inclination, ambient temperature, etc.) the message
No value
available will be shown in the center dis-
play. This does not mean that anything is
wrong in the vehicle systems.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.

MAINTENANCE AND SERVICE
577
Coolant expansion tank.Open the cap in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should notexceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in thereverse order.
CAUTION
Do not ingest the contents. May cause damage to organs (kidneys).
Use premixed coolant according toVolvo's recommendations. If concen-trated coolant is used, make sure thatthe coolant mixture is 50% coolantand 50% water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use newcoolant when replacing larger compo-nents in the cooling system.
Never run the engine unless the cool-ing system is properly filled. Animproperly filled cooling system couldlead to high temperatures and cracksin the cylinder heads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

MAINTENANCE AND SERVICE

Hybrid battery The vehicle's electric motor is powered by a rechargeable, maintenance-free, lithium-ionhybrid battery.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
NOTE
If both the starter battery and the hybrid battery are discharged, both batteries
must be charged. In such cases, it is notpossible to charge only the hybrid batteryfirst. The starter battery must have a certain level of charge for it to be possible tocharge the hybrid battery.
WARNING
Hybrid battery replacement may only be performed by a workshop – an authorizedVolvo workshop is recommended.
CoolantThe hybrid battery's cooling system has its own expansion tank.
CAUTION
Filling the hybrid battery coolant should only be performed by a workshop – anauthorized Volvo workshop is recom-mended.
Specifications for hybrid batteryType: Lithium-ion
Power reserve: 11.6 kWh.
NOTE
The capacity of the hybrid battery decrea- ses with age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.

Coolant specifications
Recommended grade: Volvo-approved pre-
mixed coolant. If concentrated coolant is used, mix with 50% water of acceptablequality (i.e. not salt water, etc.). Consult aVolvo retailer if you have any questions.
To avoid deterioration of the cooling system, engine trouble, etc., only approved Volvo cool-ant should be used.
WARNING
Coolant is hazardous if ingested and could cause damage to organs (kidneys). Theproduct contains ethylene glycol, inhibitor,water, etc.

Transmission fluid specifications
Under normal driving conditions, the trans- mission fluid will not need to be changed dur-ing the transmission's service life. However,it may need to be changed if the vehicle isdriven frequently in adverse driving condi-tions.
Automatic transmission
Prescribed transmission fluid: AW-1

Type designations (p. 624)
Brake fluid specifications
The medium in the hydraulic brake system is called brake fluid and is used to transfer brak-ing force from e.g. pressure on the brakepedal via a master brake cylinder to one ormore slave cylinders, which in turn act on amechanical brake.
Recommended grade: Volvo Original or simi-
lar fluid that meets a combination of Dot 4, 5.1 and ISO 4925 class 6.
NOTE
Changing or filling brake fluid should be entrusted to an authorized Volvo work-shop.
