STARTING AND DRIVING
||
Points to remember when filling with a
fuel can
When filling diesel with a fuel can, use the fun-
nel located under the floor hatch in the cargo
area. Make sure you insert the funnel's pipe
firmly into the filler pipe. The filler pipe has two
opening caps. The funnel's pipe must be
pushed past both caps before filling can be
started.

Diesel particulate filter
Diesel cars are fitted with particle filters for
more efficient emission control.
Particles in the exhaust gases are collected in
the diesel particle filter during normal driving.
When these conditions have been met, regen-
eration starts to burn off the particles and
empty the filter. To start regeneration, the
engine must have reached normal operating
temperature. Regeneration of the particulate
filter is automatic and normally takes
10-20 minutes.
NOTE
The following may arise during regenera-
tion:
a smaller reduction of engine power
•
may be noticed temporarily
fuel consumption may increase tempo-
•
rarily
a smell of burning may arise.
•
Use the parking heater* in cold weather - the
engine then reaches normal operating tem-
perature more quickly.
IMPORTANT
If the filter is completely filled with parti-
cles, it may be difficult to start the engine
and the filter is non-functional. Then there
is a risk that the filter will need to be
replaced.
When driving short distances at low
speeds in a diesel 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 60 km/h (38 mph) for
at least 20 minutes between each refuel-
ling.
