Fuel cap
A certain overpressure may arise in the tank
in the event of high outside temperatures.
Open the cap slowly
NOTE
Put the petrol cap back on after refuelling.
Turn until one or more clear clicks are
heard.
Filling up with fuel
Do not overfill the tank but fill until the pump
nozzle cuts out.
NOTE
Excess fuel in the tank can overflow in hot
weather.
Fuel of a quality lower than that specified in
this chapter should not be used as engine
power and fuel consumption could otherwise
be negatively affected.
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 die-
sel are highly toxic and could cause per-
manent injury or be fatal if swallowed.
Seek medical attention immediately if fuel
has been swallowed.
WARNING
Fuel which spills on to the ground can be
ignited by the exhaust fumes.
Switch off the fuel-driven heater before
starting 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.

Refuelling
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).
For detailed information on fuel consumption,
CO emissions and tank volume - see

page 296.
Petrol
Petrol must fulfil 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
exceptional cases with other engines.
•
95 RON can be used for normal driving.
•
98 RON is recommended for optimum
performance and minimum fuel consump-
tion.
When driving in temperatures above +38 °C,
fuel with the highest possible octane rating is
recommended for optimum performance and
fuel economy.
