Orange-coloured cables must only be handled by qualified personnel.
Warning
Several components in the car work with a high-voltage current that could be dangerous in the event of incorrect intervention.
- Do not touch anything that is not clearly described in the owner’s manual.
- Exercise caution when checking/refilling fluids in the engine compartment.
The appearance of the engine compartment may differ depending on the model and engine variant.
- Coolant expansion tank
- Washer fluid filler pipe
- Reservoir for brake fluid (located on the driver’s side)
- Central electrical unit
- Air filter
- Engine oil filler pipe
Location of warning decal for the engine compartment. The appearance of the engine compartment may differ depending on the model and engine variant.
Note
It is not intended that the decals illustrated in the owner’s manual should be exact replicas of those in the car. They are included to show their approximate appearance and locations in the car. The information that applies to your particular car can be found on the decal on the car.
Warning
Remember that the radiator fan (located at the front of the engine compartment, behind the radiator) may start or continue to operate automatically for up to approx. 6 minutes after the engine has been switched off. Always have the engine cleaned by a workshop – an authorised Volvo workshop is recommended. There is a risk of fire if the engine is hot.
Warning
The ignition system works at a very high and hazardous voltage. The car’s electrical system must always be in ignition position 0 when work is being performed in the engine compartment.
Do not touch the spark plugs or ignition coil when the car’s electrical system is in ignition position II or when the engine is hot.
Coolant
Prescribed grade:
Ready-mixed coolant approved by Volvo.
If the concentrated coolant is used, mix it with 50% pure water. The level of cleanliness must meet Volvo’s requirements. Consult a Volvo dealer if unsure.
In order to prevent deterioration of cooling system function, which may lead to engine malfunction among other things, it is recommended that only coolant approved by Volvo should be used.
Coolant must not be swallowed. It can cause damage to the kidneys and other organs. The product contains, among other things, ethylene glycol, inhibitor and water.
Topping up coolant
If there are signs of leakage from the cooling system – avoid starting the car and have it towed in order not to risk engine damage. Signs of leakage may be coolant under the car, that coolant visibly evaporates, or that more than 2 litres (approx. 2 quarts) are needed for topping up.
The coolant can be very hot when the engine has been running. Always allow the coolant to cool down before unscrewing the filler cap.
When filling – carefully unscrew the cap to release any overpressure.
Coolant expansion tankScrew off the cap and top up with coolant if necessary. The coolant level must lie between the MIN and MAX marks on the expansion tank.
Important
- Coolant is harmful to ingest and may cause organ damage.
- Only use coolant of Volvo-approved quality. If the concentrated liquid is used, make sure that the ratio is 50 % coolant to 50 % water of approved quality.
- Hard water and water with a high content of chlorine, chlorides and other salts or contaminants may cause corrosion to the cooling system.
- Do not mix different coolants.
- New coolant must be used to replace all coolant when replacing a large component in the cooling system.
- Only operate the engine when the cooling system is filled to the correct level. When the coolant level is too low, it may lead to overheating, resulting in engine damage.
Engine oil
Location of warning decal for the engine compartment. The appearance of the engine compartment may differ depending on the model and engine variant.
Volvo recommends:
If the engine oil cannot be checked on a regular basis and the level falls too low, there is a risk that this will cause serious damage to the engine.
Note
It is not intended that the decals illustrated in the owner’s manual should be exact replicas of those in the car. They are included to show their approximate appearance and locations in the car. The information that applies to your particular car can be found on the decal on the car.
Important
- In order to fulfil the requirements for the engine’s service intervals, all engines are filled with specially adapted synthetic engine oil at the factory.
- The choice of oil has been made very carefully with regard to service life, starting characteristics, fuel consumption and environmental impact.
- Approved engine oil must be used in order that the recommended service intervals can be applied. Only use a prescribed grade of oil for both filling and oil change, otherwise, there is a risk of the service life,
- starting characteristics, fuel consumption and environmental impact of the car affected.
- If engine oil of the prescribed grade and viscosity is not used, engine-related components may become damaged. Volvo disclaims any liability for any such damage.
- Volvo recommends that oil changes are carried out at an authorised Volvo workshop.
Symbols for low oil level
Volvo uses different systems to warn about the oil level or low oil pressure. Low oil pressure is indicated by a warning symbol 
in the driver display. Warning or information about the car’s oil level can be
indicated by a warning symbol 
in the driver display as well as message texts. Contact a Volvo dealer for more information.
Change the engine oil and oil filter in accordance with the intervals specified in the Service and Warranty Booklet.
Checking and filling with engine oil
See the oil level in the centre display
Example of oil level display.The oil level can only be shown when the car has been started. The oil level should be checked regularly.
Open the Car Status app from the app view in the centre display.
Press Status to show the oil level.
Note
The system cannot directly detect changes when the oil is filled or drained out. The car must have been driven approx. 30 km (approx. 20 miles) and have been stationary for 5 minutes with the engine switched off and on level ground before the oil level indication is correct.
If the right conditions for measuring the oil level (time after engine shutdown, the car’s inclination, outside temperature, etc.) are not met, then the message No value available will be shown on the centre display. This does not mean that there is something wrong with the car’s systems.
Important
If this symbol is shown then the oil pressure may be too low. Stop the car as quickly as possible and have the car recovered to a workshop – an authorised Volvo workshop is recommended.
Fill the engine oil
Important
If a message prompts you to top up the engine oil, only fill it with the specified amount. If the level is too high, it may result in operational disruption.
Filler pipe,.In some cases, the oil may need to be topped up between service intervals. No action with regard to engine oil level needs to be taken until a message is shown in the driver display.
Warning
If the Engine oil level Service required message is shown, visit a workshop – an authorised Volvo workshop is recommended. The oil level may be too high.
Warning
Take care not to spill any oil in the engine compartment. This may lead to a fire if the oil comes into contact with hot parts.

Fuses in engine compartment
Updated 5/30/2022
Fuses in the engine compartment protect engine and brake functions, amongst other things.
The fuse box provides space for several spare fuses.Positions
Fuse locations are shown on the inside of the cover. Functions and components in the fuse table cover several models and engine alternatives. A fuse description can therefore apply to fewer than those in the table, or be completely missing, depending on how the car is equipped. If a position has several values in the table, the value depends on variations in equipment level. In which case, follow the value of the fuse being replaced. In the event of doubt – contact a workshop. An authorised Volvo workshop is recommended.
