Starting The Engine - Flexifuel - Volvo V70 Owner's Manual

08 Starting and driving
Starting the engine – Flexifuel
Flexifuel engines can be driven on 95 octane
unleaded petrol and bioethanol E85. The
engine 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 reduced
emissions and reduced fuel consumption. For
this reason you should aim to use the engine
block heater throughout the winter months.
•
In outside temperatures between
+5 °C and -10 °C, the electric engine
block heater should be activated for at
least 1 hour.

block heater should be activated for at
least 2 hours.
•
In outside temperatures lower than
-20 °C, the electric engine block heater
should be activated for at least 3 hours.
WARNING
The engine block heater is powered by
high voltage. Fault tracing and repair of an
electric engine block heater and its electri-
cal connections must only be carried out
by 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 a
reserve fuel can may make the engine
difficult to start in extreme cold. This is
avoided by filling the reserve fuel can
with 95 octane petrol.
For more information on Flexifuel's bioethanol
E85 fuel, see Fuel - bioethanol E85 (p. 292).
In the event of starting difficulties
If the engine does not start at the first start
attempt:
•
Make further attempts to start with the
START/STOP ENGINE button.
•
Check that the engine block heater has
been 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 recommended
to contact an authorised Volvo workshop.
Fuel adaptation
Flexifuel engines can be driven on both 95
octane unleaded petrol and bioethanol E85.
Both fuels are filled in the common fuel tank
so that any variations of mixing ratios
between these two fuels is possible.
If the fuel tank is filled with petrol after the car
has been driven on bioethanol E85 (or vice
versa) then the engine may run slightly
unevenly for a time. For this reason it is
important to allow the engine to accustom
itself (adapt) to the new fuel mixture.
Adaptation takes place automatically when
the car is driven for a short period at an even
speed.
