Engine oil
For the recommended service intervals and war-ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
If the engine oil is not checked regularly and thelevel becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine'sservice 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 toapply, 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 prescribedgrade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage.
Volvo recommends entrusting oil changes toan authorized Volvo workshop.
Volvo uses different systems to warn if the oillevel 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 displaymessages 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 tothe 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.
