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 converters
The 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-sond
TM
oxygen sensor
The 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 fulfil the EN 228 standard. Most
engines can be run with octane ratings of 95
and 98 RON. Only in exceptional cases should
91 RON be used.
•
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.
