Engine oil For the recommended service intervals and warranties to be applied, an approved engineoil must be used.
Volvo recommends:
If the engine oil is not checked regularly and the level becomes low, this could cause seri-ous engine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filled with a specially adapted syntheticengine oil. Great care has been put into thechoice of oil, with consideration given toservice life, startability, fuel consumptionand environmental impact. For the recommended service intervals to apply, an approved engine oil must beused. Only use the prescribed oil grade totop off or change the oil. Otherwise, thereis a risk of the vehicle's service life, starta-bility, fuel consumption and environmentalimpact being affected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Cor-poration disclaims warranty liability forsuch type of 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.On engine variants with an oil pressure sensor,

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.
