Engine oil
An approved engine oil must be used in order that the recommended service intervals can beapplied.
Volvo recommends:
IMPORTANT
In order to fulfil the requirements for the engine's service intervals all engines are filledwith a specially adapted synthetic engine oilat the factory. The choice of oil has beenmade very carefully with regard to service life,starting characteristics, fuel consumption andenvironmental impact. An approved engine oil must be used in order that the recommended service intervals canbe applied. Only use a prescribed grade of oilfor both filling and oil change, otherwise thereis a risk of the service life, starting characte-ristics, fuel consumption and environmentalimpact of the car being affected. If engine oil of the prescribed grade and vis- cosity is not used, engine related componentsmay become damaged. Volvo Car Corporationdisclaims any liability for any such damage. Volvo recommends that oil changes are car- ried out at an authorised Volvo workshop.
Volvo uses different systems for warning of low/ high oil level or low oil pressure. Certain enginevariants have an oil pressure sensor, and then thedriver display's warning symbol for low oil pres- sure
is used. Other variants have an oil
level sensor, when the driver is informed via the driver display's warning symbol
and display texts. Certain variants have both systems. Contact a Volvo dealer for more information. Change the engine oil and oil filter in accordance with the intervals specified in the Service andWarranty Booklet. Using oil of a higher than specified grade is per- mitted. If the car is driven in adverse conditions,Volvo recommends using an oil of a higher gradethan the one specified.

.
In some cases, oil may need to be topped up between service intervals. Action with regard to engine oil level does not need to be taken until a message is shown in thedriver display.
WARNING
If this symbol is shown together with the message Engine oil level
Service required, visit a workshop
- an authorised Volvo workshop is
recommended. The oil level may be too high.
IMPORTANT
If this symbol is shown together with a message about low oil level, such as
Engine oil level low
Refill 1 litre for example, then only
fill the volume specified, e.g. 1 litre.
WARNING
Do not spill oil onto the hot exhaust manifold due to the risk of fire.
Check the oil level
1. Open the Car status app from the app view
in the centre display.
2. Press the
Status button to show the oil
level.
Graphics for oil level in the centre display.
The oil level is checked using the electronic oil level gauge in the centre display when the engineis switched off.
NOTE
The system cannot directly detect changes when the oil is filled or drained. The car musthave been driven approx. 30 km and havebeen stationary for 5 minutes with the engineswitched off and on level ground before theoil level indication is correct.
8 Engines with electronic oil level sensor do not have a dipstick.

If the right conditions for measuring the oil level (time after engine shutdown, the car'sinclination, outside temperature, etc.) are not met, then the message
No value availablewill be shown in the centre display. This does not mean that there is something wrong in
the car's systems.

Topping up coolant
The coolant cools the internal combustion engine to the correct operating temperature. Theheat that is transferred from the engine to thecoolant can be used to heat the passenger com-partment.
When topping up the coolant, follow the instruc- tions on the packaging. Never top up with wateronly. The risk of freezing increases with both toolittle and too much coolant concentrate.
WARNING
Coolant can be very hot. If the coolant requires topping up when the engine is atoperating temperature, unscrew the expan-sion tank cap slowly to gently release theoverpressure.
Coolant expansion tank, left-hand drive car.
Screw off the cap in the plastic cover.
Screw off the cap on the expansion tank and top up with coolant. The coolant level must not exceed the yellow MAX mark inside the
expansion tank.
Reinstall the parts in reverse order.
