• EN 228 E10 petrol (max10 percent by volume ethanol) isapproved for use.
• Ethanol higher than E10 (max.10 percent by volume ethanol) is not per-mitted, e.g. E85 is not permitted.
Octane rating
•95 RON can be used for normal driving.
• 98 RON is recommended for optimum per- formance and minimum fuel consumption.
When driving in temperatures above +38 °C, fuelwith the highest possible octane rating is recom-mended for optimum performance and fuel econ-omy.

Diesel Diesel is a type of engine fuel that is intended for cars with a diesel engine.
Only use diesel fuel from well-known producers. Never use fuel of dubious quality. Diesel fuelmust fulfil the EN 590 or SS 155435 standard.Diesel engines are sensitive to contaminants inthe fuel, such as excessively high volumes of sul-phur and metals. At low temperatures (lower than 0 °C) a paraffin precipitate may form in the diesel fuel, which maylead to ignition problems. The fuel qualities thatare sold must be adapted for season and climatezone, but for extreme weather conditions, old fuelor moving between climate zones, paraffin precip-itate may occur. The risk of condensation in the fuel tank is reduced if the tank is kept well filled. When refuelling, check that the area around the fuel filler pipe is clean. Avoid spilling fuel onto thepaintwork. Wash off any spillage with detergentand water.
IMPORTANT
Diesel fuel must: •fulfil the EN 590 and/or SS 155435 standards
• have a sulphur content not exceeding10 mg/kg
• have a maximum of 7 vol % FAME 15
(B7).
IMPORTANT
Diesel type fuels that must not be used:
• Special additives
• Marine diesel fuel
• Heating oil
• FAME 16
and vegetable oil.
These fuels do not fulfil the requirements in accordance with Volvo recommendations andgenerate increased wear and engine damagethat is not covered by the Volvo warranty.

Empty tank and diesel engine
Once the engine has stopped due to fuel starva- tion, the fuel system needs a few moments tocarry out a check.
Before starting the engine after the fuel tank has
been filled with diesel - proceed as follows:
1. The remote control key must be inside the car.
2. Set the car in ignition position II - turn the
ignition dial to START without depressing
the brake pedal and hold the knob in the START position for approx. 4 seconds. Then
release the knob, which automatically returns to its starting position.
3. Wait approx. one minute.
4. To start the engine: Depress the brake pedal and turn the ignition dial to START again.
NOTE
Before filling with fuel in the event of fuel shortage:
• Stop the car on as flat/level ground aspossible - if the car is tilting there is a riskof air pockets in the fuel supply.
