General information on fuel
WARNING
Always avoid inhaling fuel vapour and get-
ting fuel splashes in the eyes.
In the event of fuel in the eyes, remove any
contact lenses and rinse the eyes in plenty
of water for at least 15 minutes and seek
medical attention.
Never swallow fuel. Fuels such as petrol,
bioethanol and mixtures of them and diesel
are highly toxic and could cause permanent
injury or be fatal if swallowed. Seek medical
attention immediately if fuel has been swal-
lowed.
WARNING
Fuel which spills on to the ground can be
ignited by the exhaust fumes.
Switch off the fuel-driven heater before star-
ting to refuel.
Never carry an activated mobile phone
when refuelling. The ring signal could cause
spark build-up and ignite petrol fumes,
leading to fire and injury.
IMPORTANT
Mixing different types of fuel or the use of
fuel not recommended invalidates Volvo's
guarantees, and any associated service
agreement. This applies to all engines.
NOTE: It does not apply to cars with engines
that are adapted to run on ethanol fuel (E85).

consumption and tank volume, see page 285.
Petrol
Petrol must meet the EN 228 standard. Most
engines can be run with octane ratings of 91,
95 and 98 RON.
•
91 RON must not be used for 4-cylinder
engines and should only be used in excep-
tional cases with other engines.
•
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,
fuel with the highest possible octane rating is
recommended for optimum performance and
fuel economy.
