Checking and filling engine oilThe engine oil level is monitored by an electronic oil level sensor.
Filler pipe 12
.
It may be necessary to top up engine oil between regularly scheduled services. No action is necessary with regard to engine oil level until a message appears in the instrumentpanel.
WARNING
If this symbol is shown together with the message Engine oil level
Service required, visit a workshop
– an authorized Volvo workshop is
recommended. The oil level may be too high.
CAUTION
If this symbol is shown together with a message about low oil level, for example
Engine oil level low
Refill 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 as this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the electronic oil 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 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 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.

Engines with an electronic oil level sensor do not have a dipstick.

NOTE
If the conditions for measuring oil level are not 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 does not mean that anything is wrong in the vehi-
cle systems.

Refilling coolant
Coolant helps keep the combustion engine at the 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 on the 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 from the 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 unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
Coolant expansion tank, left-hand drive vehicle.

MAINTENANCE AND SERVICE
* Option/accessory.603
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should not exceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in the reverse order.
CAUTION
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
• Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
• High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
Halogen headlights are not available on all mod- els and markets. Contact a Volvo retailer formore information. LED 13
bulbs must be replaced by a workshop.
An authorized Volvo workshop is recommended.
NOTE
For information on lights not mentioned in this article, contact a Volvo dealer or a certi-fied Volvo service technician.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.

Start battery
The vehicle has a single-pole electrical system that uses the chassis and engine mount as con-ductors. 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 15
.
The start battery is a 12 V AGM (Absorbed Glass Mat) 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, which is 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.
Connection points
WARNING
PROPOSITION 65 WARNING Battery posts, terminals, and related accesso- ries contain lead and lead compounds, chemi-cals known to the state of California to causecancer and reproductive harm. Wash handsafter handling. Use the vehicle's connection points in the engine compartment to connect an external start batteryor battery charger. The battery terminals on the car's starter battery in the luggage/cargo area must
not be used.
Positive connection point
Negative connection point
CAUTION
It is not possible to charge another vehicle's battery 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.

An authorized Volvo workshop is recommended.

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 bat- tery are discharged, both batteries must be
charged. In such cases, it is not possible to charge only the hybrid battery first. The starter battery must have a certain level of charge for it to be possible to charge thehybrid battery.
WARNING
Hybrid battery replacement may only be per- formed by a workshop – an authorized Volvoworkshop 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 – an authorizedVolvo workshop is recommended.
SpecificationsType: Lithium-ion
Power reserve: 10.4 kWh.
NOTE
The capacity of the hybrid battery decreases with age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.

Replacing fuses All electrical functions and components are pro- tected by a number of fuses in order to protectthe vehicle's electrical system from damage byshort circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
2. Pull out the fuse and examine it from the
side to determine if the curved metal wire in the fuse is intact.
3. If the wire is broken, replace the fuse with a new fuse of the same color and amperage.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possiblylead to a fire.
WARNING
Contact an authorized Volvo workshop for assistance replacing fuses not listed in theOwner's Manual. If performed incorrectly, sig-nificant damage can be caused to the electri-cal system.
