MAINTENANCE AND SERVICE
588If the engine oil is not checked regularly and the level becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact. For the recommended service intervals to apply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low. Onengine variants with an oil pressure sensor, a
warning symbol is displayed in the instrument panel when oil pressure is low
. On engine
variants with an oil level sensor, the
warn-
ing symbol in the instrument panel and display messages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information. Change the engine oil and oil filter according to the schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.

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.

Fuses and fuseboxes
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.
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.
If any electrical component or function is not responding, the component may have blown afuse due to temporary overload. If the same fuseblows repeatedly, there may be a problem withthe component. Volvo recommends contacting anauthorized Volvo workshop to have the compo-nent checked.
