Make further attempts to start with the
START/STOP ENGINE
button.
•
Check that the engine block heater has
been plugged in and, where appropriate,
connect it for the time indicated 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.
IMPORTANT
After the fuel mixture in the tank has been
changed an adaptation should be made by
driving at an even speed for about 15
minutes.
If the starter battery has been discharged or
disconnected then a slightly longer period of
driving is required for the adaptation as the
memory for the electronics has been cleared.

Jump starting with battery
If the starter battery (p. 361) is discharged
then the car can be started with current from
another battery.
When jump starting the car, the following
steps are recommended to avoid short cir-
cuits or other damage:
1. Set the car's electrical system in key
position 0 , see Key positions - functions
at different levels (p. 74).
2. Check that the donor battery has a volt-
age of 12 V.
3. If the donor battery is installed in another
car - switch off the donor car's engine
and make sure that the two cars do not
touch each other.
