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.

Replacing bulbs
This vehicle is equipped with only LED 16
lights, which means it does not have any replaceable bulbs. Contact a workshop 15
if
you experience any problems with the light- ing. If there is a problem with an LED 16
light, the
entire lamp unit will normally need to be replaced.
NOTE
For information on lights not mentioned in the Owner's Manual, contact a Volvodealer or a certified Volvo service techni-cian.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.
NOTE
Bulbs for active curve lighting * contain
traces of mercury and should therefore always be submitted to a certified Volvoservice technician.

Start battery
The vehicle has a single-pole electrical sys- tem that uses the chassis and engine mountas conductors. The start battery is used to start the electrical system and power electrical equipment in thevehicle. The hybrid battery is used to start thecombustion engine. The start battery should only be replaced by a workshop 17
.
The start battery is a 12 V AGM (Absorbed Glass Mat) battery, dimensioned for regenera-tive charging and to support the function ofthe vehicle's various systems. The service life and performance of the start battery are affected by factors such as drivingstyle, driving conditions, climate, battery dis-charges, number of starts, etc. Never disconnect the start battery while the engine is running.
Make sure the cables to the start batteryare correctly connected and the clampsare securely tightened.
WARNING
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable toany part of the fuel system or to anymoving parts. Avoid touching hotmanifolds.
Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces.
If contact occurs, flush the affectedarea immediately with water. Obtainmedical help immediately if eyes areaffected.
Never expose the battery to open flameor electric spark. Do not smoke nearthe battery. Failure to follow theinstructions for jump starting can leadto injury.

WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
Use the vehicle's connection points in the engine compartment to connect an externalstart battery or battery charger. The battery terminals on the car's start battery in the luggage/cargo area must not be used.

Positive connection point
Negative connection point
CAUTION
It is not possible to charge another vehi- cle's battery by supplying current throughthe charging points. Using the chargingpoints to charge another vehicle's batterycould cause a fuse to blow, which wouldcause the charging points to stop working.
CAUTION
Only a modern battery charger with con- trolled charge voltage should be used tocharge the starter battery. The rapid charg-ing function should not be used as thiscould damage the battery.
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.
CAUTION
Failure to observe the following could cause the infotainment energy save modeto temporarily stop working and/or a mes-sage in the driver's display regarding thestate of charge of the starter battery maybe temporarily incorrect after an externalstarter battery or battery charger has beenconnected:
The negative battery terminal of thevehicle's starter battery must
never be
used to connect an external starterbattery or battery charger – only thevehicle's negative charging pointshould be used as a grounding point.

NOTE
If the starter battery becomes discharged too many times, it will shorten its servicelife. The service life of the starter battery is affected by several factors, such as drivingconditions and climate. The startingcapacity of the battery reduces graduallyover time. The battery must therefore berecharged if the vehicle is not used or along period of time or if it is only drivenshort distances. Severe cold further limitsthe 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 shouldbe connected to a battery charger withautomatic trickle charging. A starter battery that is always kept fully charged has the maximum service life.Location
The start battery is located in the cargo compart- ment.
WARNING
If the starter battery is disconnected, the function for automatic opening and closingmust be reset to function correctly. A resetis required in order for the pinch protectionto work.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that thetensioning strap is always securely tight-ened.

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.
