Diesel particle filter (DPF) 1
Diesel cars may be 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 filter takes place automatically
at an interval of 300 – 900 km depending
on driving conditions. Regeneration
normally takes between 10 and 20 minutes.
During this time fuel consumption may increase
slightly.
The rear window heating may be activated
automatically to increase the load on the engine
during regeneration without warning.
– Apply the parking brake.
Automatic gearbox
– Gear selector in position P or N.
Manual gearbox
Put the gear lever in neutral and hold the
clutch pedal fully depressed. This is particularly
important in very cold conditions.
WARNING
Never remove the ignition key from the
steering lock while driving or when the car is
being towed. The steering lock could otherwise
be activated, making it impossible to
steer the car.
The ignition key must be in position II when
the car is being towed.
NOTE
The idling speed can be noticeably higher
than normal for certain engine types during
cold starting. This is so that the emissions
system can reach normal operating temperature
as quickly as possible, which minimises
exhaust emissions and protects the
environment.
Petrol
– Turn the ignition key to position III.
If the engine does not start within
5–10 seconds, release the key and try
again.
Diesel
1. Turn the ignition key to position II.
An indicator symbol in the combined instrument
panel shows that engine preheating
is underway, see page 43.
2. Turn the ignition key to position III
when the indicator symbol goes out.
Autostart (5-cylinder)
With the autostart function, there is no need
to hold the ignition key (or ignition dial on
cars with Keyless Drive, see page 104) in
position III until the engine has started.
Turn the ignition key to the start position and
then release. The starter motor then works
automatically until the engine has started.
NOTE
If the diesel engine is started in extreme
cold without waiting for engine preheating,
then the automatic start sequence can be
delayed for a couple of seconds.
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 approximately
80% full of particles, the yellow information
