STARTING AND DRIVING
487
When driving in temperatures above +38 °C
(100 °F), fuel with the highest octane rating is
recommended for adapted performance and
fuel economy.
IMPORTANT
•
Use only unleaded petrol to avoid dam-
aging the catalytic converter.
•
Fuel containing metallic additives must
not be used.
•
Do not use any additives which have
not been recommended by Volvo.

Petrol particle filter
11
Petrol cars are fitted with particle filters for
more efficient emission control.
Particles in the exhaust gases are collected in
the petrol particle filter during normal driving.
In normal driving conditions, passive regenera-
tion takes place, which leads to the particles
being oxidised and burned away. The filter is
emptied in this way.
If the car is driven at low speed or with repea-
ted cold starts in low outside temperature,
active regeneration may be necessary. Regen-
eration of the particulate filter is automatic and
normally takes 1020 minutes. Fuel consump-
tion may temporarily increase during regenera-
tion.
When driving short distances at low
speeds in a petrol car
The capacity of the emissions system is affec-
ted by how the car is driven. Driving varying
distances and at different speeds is important
in order to achieve performance that is as
energy-efficient as possible.
Driving short distances at low speeds (or in
cold climates) frequently, where the engine
does not reach normal operating temperature,
can lead to problems that can eventually
cause a malfunction and trigger a warning
message. If the vehicle is mostly driven in city
traffic, it is important to regularly drive at
higher speeds to allow the emissions system
to regenerate.
•
The car should be driven on A-roads at
speeds in excess of 70 km/h (44 mph) for
at least 20 minutes between each refuel-
ling.
