STARTING AND DRIVING
298
To bear in mind when you have run out
of fuel
Avoid running out of fuel. In the event of an
empty tank, it is possible to continue driving with
the available charge in the hybrid battery. After
refilling the fuel, it may seem to take longer to
start the engine (up to 30 seconds). In certain
cases, repeated attempts to start the car may
also be required.
Once the engine has been started, it is recom-
mended to keep it running for at least 5 minutes.
Select drive mode AWD or POWER in order to
facilitate the supply of fuel.
If the message
Internal combustion engine
unavailable Limited performance and
mileage is shown in the combined instrument
panel's information display - switch off and then
restart the engine again to regain full function.
Draining condensation from the fuel
filter
13
The fuel filter separates condensation from the
fuel. Condensation can disrupt engine operation.
For optimum performance, it is important to fol-
low the service intervals for fuel filter change as
well as to use genuine parts developed specifi-
cally for this purpose.
The fuel filter must be drained at the intervals
specified in the Service and Warranty Booklet or
if you suspect that the car has been filled with
contaminated fuel. For more information, see
Volvo service programme (p. 356).
IMPORTANT
Certain special additives remove the water
separation in the fuel filter.

Diesel particle filter (DPF)
Diesel cars are equipped with a particle filter,
which results in more efficient emission control.
The particles in the exhaust gases are collected
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 particle filter is automatic
and normally takes 10-20 minutes. It may take a
little longer at a low average speed. Fuel con-
sumption may increase slightly during regenera-
tion.
During regeneration, charging of the hybrid bat-
tery is activated temporarily in the background,
which is similar to the SAVE function, see Drive
system - drive modes (p. 270).
Regeneration in cold weather
If 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 approx. 80% full of
particles, a yellow warning triangle is shown in
the combined instrument panel, and the message
13
Applicable to five-cylinder engines only.
