Petrol particle filter
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 regeneration
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 repeated
cold starts in low outside temperature, active
regeneration may be necessary. Regeneration of
the particulate filter is automatic and normally
takes 10-20 minutes. There may be a smell of
burning during regeneration.
Use the parking heater in cold weather - the
engine then reaches normal operating tempera-
ture more quickly.
When driving short distances at low
speeds in a petrol car
The capacity of the emissions system is affected
by how the car is driven. It is important to drive
varying distances at different speeds to achieve
optimal performance.
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 regu-
larly drive at higher speeds to allow the emissions
system to regenerate.
The car should be driven on A-roads at
•
speeds in excess of 60 km/h (38 mph) for at
least 20 minutes between each refuelling.

STARTING AND DRIVING
Diesel
Diesel is a type of engine fuel that is intended for
cars with a diesel engine.
Only use diesel fuel from well-known producers.
Never use fuel of dubious quality. Diesel fuel
must fulfil the EN 590 or SS 155435 standard.
Diesel engines are sensitive to contaminants in
the fuel, such as excessively high volumes of sul-
phur and metals.
Identifier
Decal on the inside of the fuel filler flap.
The identifier in accordance with the CEN stand-
ard EN16942 is located on the inside of the fuel
filler flap, and will be on corresponding fuel
pumps and their nozzles at filling stations
throughout Europe by 12 October 2018 at the
latest.
This is the identifier that applies for current
standard fuel in Europe. Diesel with the following
identifiers may be used in cars with diesel
engine:
