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.

IMPORTANT
When replacing the starter battery or support battery, a battery of AGM 15
type must be fit-
ted.
NOTE
• The higher the current take-off in the car, the more the alternator must be workingand the batteries charging = Increasedfuel consumption.
• When the capacity of the starter batteryhas fallen below the lowest permissiblelevel then the Start/Stop function is dis-engaged.
Temporarily reduced Start/Stop function due to high current take-off means: •
The engine starts automatically 16
without the
driver depressing the clutch pedal (manualgearbox).
• The engine starts automatically without thedriver lifting his/her foot off the foot brakepedal (automatic gearbox).
The support battery normally requires no moreservice than the normal starter battery. A work-shop should be contacted in the event of ques-tions or problems - an authorised Volvo workshopis recommended.
IMPORTANT
If the following instruction is not observed then the Start/Stop function may temporarilycease to work after the connection of anexternal starter battery or battery charger:
• The negative battery terminal on the car's starter battery must
never be used for
connecting an external starter battery orbattery charger - only the car's negative
charging point may be used as the
grounding point.
NOTE
If the starter battery has been discharged so much that the car has no normal electricalfunctions and the engine is then jump-startedwith an external battery or a battery charger,the Start/Stop function will continue to beactivated. If the Start/Stop function thenauto-stops the engine shortly after, there is agreat risk that engine auto-start will fail dueto insufficient battery capacity, because thebattery has not had the opportunity torecharge. If the car has been jump-started, or if there is insufficient time to charge the battery with abattery charger, the recommendation is totemporarily deactivate the Start/Stop functionuntil the battery has been recharged by thecar. In an outside temperature of +15 °C, thebattery needs to be charged for at least1 hour by the car. In a lower outside tempera-ture, the charging time may increase to3-4 hours. The recommendation is to chargethe battery using an external battery charger.

Adverse driving conditions for engine oil Adverse driving conditions can lead to abnor- mally high oil temperature or oil consumption.Below are some examples of adverse drivingconditions.
Check the oil level more frequently for long jour- neys:• towing a caravan or trailer
• in mountainous regions
• at high speeds
• in temperatures colder than -30 °C or hotterthan +40 °C.
The above also apply to shorter driving distancesat low temperatures. Choose a fully synthetic engine oil for adverse driving conditions. It provides extra protection forthe engine.

Fuel consumption and CO2 emissions
Fuel consumption and CO2 emissions can be affected negatively by several causes.
Examples of reasons for increased fuel consump- tion are as follows:• If the car is equipped with extra equipmentthat affects the car's weight.
• The driver's driving style.
• If the customer chooses wheels other thanthose fitted as standard on the model's basicversion then rolling resistance may increase.
• High speed results in increased wind resis-tance.
• Fuel quality, road and traffic conditions,weather and the condition of the car.
A combination of the above-mentioned examplescan result in significantly increased consumption.
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combina-tion with fuel quality are factors that consider-ably increase the car's fuel consumption.
