Starting The Engine - Volvo S40 Owner's Manual

Before starting the engine
– 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 particu-
larly 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 other-
wise 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 temper-
ature as quickly as possible, which mini-
mises exhaust emissions and protects the
environment.

Starting the engine

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
– Turn the ignition key to position II.
An indicator symbol in the combined
instrument panel shows that engine pre-
heating is underway, see page 41.
– 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 122) 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.

Diesel particle filter (DPF)
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 driv-
ing. 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 auto-
matically at an interval of 300 – 900 km
depending on driving conditions. Regenera-
tion normally takes between 10 and
20 minutes. During this time fuel consump-
tion may increase slightly.
The rear window heating may be activated
automatically to increase the load on the
engine during regeneration without warning.
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
