General information on fuel
Fuel of a lower quality than that recommended
by Volvo must not be used as engine power
and fuel consumption is negatively affected.
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 onto the ground can be
ignited.
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).
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combi-
nation with fuel grade are factors that could
affect the car's performance.
Catalytic convertersThe purpose of the catalytic converters is to
purify exhaust gases. They are located close to
the engine so that operating temperature is
reached quickly.
The catalytic converters consist of a monolith
(ceramic or metal) with channels. The channel
walls are lined with a thin layer of platinum/rho-
dium/palladium. These metals act as catalysts,
i.e. they participate in and accelerate a chem-
ical reaction without being used up them-
selves.
Lambda-sondTM oxygen sensorThe Lambda-sond is part of a control system
intended to reduce emissions and improve fuel
economy.
An oxygen sensor monitors the oxygen content
of the exhaust gases leaving the engine. This
value is fed into an electronic system that con-
tinuously controls the injectors. The ratio of fuel
to air directed to the engine is continuously
adjusted. These adjustments create optimal
conditions for efficient combustion, and
together with the three-way catalytic converter
reduce harmful emissions (hydrocarbons, car-
bon monoxide and nitrous oxides).
Petrol
Petrol must meet the EN 228 standard. Most
engines can be run with octane ratings of 95
and 98 RON. 91 RON should only be used in
exceptional cases.
•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.

272* Option/accessory, for more information, see Introduction.
Diesel particle filter (DPF)Diesel cars are equipped with a particle filter,
which results in more efficient emission con-
trol. The particles in the exhaust gases are col-
lected in the filter during normal driving. So-
called "regeneration" is started in order to burn
away the particles and empty the filter. This
requires the engine to have reached normal
operating temperature.
Regeneration of the filter takes place automat-
ically at an interval of approximately
300-900 km depending on driving conditions.
Regeneration normally takes 10-20 minutes. It
may take a little longer at a low average speed.
Fuel consumption may increase slightly during
regeneration.
Regeneration in cold weatherIf the car is frequently driven short distances in
cold weather then the engine does not reach
normal operating temperature. This means that
regeneration of the diesel particle filter does
not take place and the filter is not emptied.
When the filter has become approximately
80% full of particles, a warning triangle on the
instrument panel illuminates, and the message
Soot filter full. See manual is shown on the
instrument panel display.
Start regeneration of the filter by driving the car
until the engine reaches normal operating tem-
perature, preferably on a main road or motor-way. The car should then be driven for approx-
imately 20 minutes more.
NOTE
A smaller reduction of engine power may be
noticed temporarily during regeneration.
When regeneration is complete the warning
text is cleared automatically.
Use the parking heater* in cold weather so that
the engine reaches normal operating tempera-
ture more quickly.
IMPORTANT
If the filter fills up with particles then it can
be difficult to start the engine and the filter
will be incapable of functioning. Then there
is a risk that the filter will have to be
replaced.
Fuel consumption and emissions of
carbon dioxide
Fuel consumption figures may change if the car
is equipped with extra equipment that affects
the car's weight. See information on weights
page 347 and table page 354.
The manner in which the car is driven, and
other non-technical factors can also affect fuel
consumption.Consumption is higher and power output lower
for fuel with an octane rating of 91 RON.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combi-
nation with fuel grade are factors that could
affect the car's performance.
