Starting the engine – Flexifuel
Flexifuel engines can be driven on 95 octane unleaded petrol and bioethanol E85. Theengine is started in the same way as in a pet-rol-driven car.
Engine block heater*
Electrical input to the engine block heater.
Cars intended for E85 have an electric engine block heater. Starting and driving with a pre-heated engine means significantly reducedemissions and reduced fuel consumption. Forthis reason you should aim to use the engineblock heater throughout the winter months. • In outside temperatures between +5 °C and -10 °C, the electric engineblock heater should be activated for atleast 1 hour.
• In outside temperatures between-10 °C and -20 °C, the electric engine block heater should be activated for atleast 2 hours.
• In outside temperatures lower than-20 °C, the electric engine block heatershould be activated for at least 3 hours.
WARNING
The engine block heater is powered by high voltage. Fault tracing and repair of anelectric engine block heater and its electri-cal connections must only be carried outby a workshop - an authorised Volvo work-shop is recommended.
NOTE
Points to remember for carrying reserve fuel:
• In the event of stalling due to an empty fuel tank, bioethanol E85 from areserve fuel can may make the enginedifficult to start in extreme cold. This isavoided by filling the reserve fuel canwith 95 octane petrol.
For more information on Flexifuel's bioethanol E85 fuel, see Fuel - bioethanol E85 (p. 304).
In the event of starting difficultiesIf the engine does not start at the first startattempt: •
Make further attempts to start with the START/STOP ENGINE
button.
• Check that the engine block heater hasbeen activated and, where appropriate,activate it for the time specified above.
IMPORTANT
If the engine does not start despite repea- ted start attempts, you are recommendedto contact an authorised Volvo workshop.
Fuel adaptationFlexifuel engines can be driven on both 95 octane unleaded petrol and bioethanol E85.Both fuels are filled in the common fuel tankso that any variations of mixing ratiosbetween these two fuels is possible. If the fuel tank is filled with petrol after the car has been driven on bioethanol E85 (or viceversa) then the engine may run slightlyunevenly for a time. For this reason it isimportant to allow the engine to accustomitself (adapt) to the new fuel mixture. Adaptation takes place automatically when the car is driven for a short period at an evenspeed.

Fuel - bioethanol E85
Bioetanol E85 is used as the fuel for the car's engine. Do not modify the fuel system or its compo- nents, and do not replace components withparts that are not specifically designed foruse with bioethanol.
WARNING
Methanol must not be used. A decal on the inside of the fuel filler flap shows thecorrect alternative fuel. The use of components not designed for bioethanol engines could cause fire, injuryor engine damage.
Reserve fuel canThe reserve fuel can should be filled with pet- rol. For more information, see Starting theengine – Flexifuel (p. 269).
IMPORTANT
Make sure the reserve fuel can is securely fastened and that its cap is sealed.
WARNING
Ethanol is sensitive to sparks, and explo- sive gases could form in the reserve fuelcan if it is refuelled with ethanol.
