Starting The Engine - Volvo XC90 Owner's Manual

06 Starting and driving

Starting the engine

Before starting the engine
– Apply the parking brake.
Automatic gearbox
– Gear selector in position P or N.
Manual gearbox
– Shift the gear lever into 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 other-
wise be activated, making it impossible to
steer the car.
The ignition key must be in position II when
06
the car is being towed.
NOTE
The master key blade must be fully extend-
ed (as illustrated on page 100) when start-
ing the car. Otherwise there is a risk that the
immobiliser function will prevent the car
from starting.

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 minimis-
es 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
1. Turn the ignition key to position II.
An indicator symbol in the combined in-
strument panel shows that engine pre-
heating is underway, see page 46.
2. Turn the ignition key to position III
when the indicator symbol goes out.

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 fil-

ter. 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 de-
pending on driving conditions. Regeneration
normally takes between 10 and 20 minutes.
During this time fuel consumption may in-
crease slightly.
The rear window heating may be activated
automatically to increase the load on the en-
gine 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
symbol on the dashboard illuminates,
and the message SOOT FILTER FULL
SEE MANUAL is shown on the dashboard
display. Start regeneration of the filter by
driving the car until the engine reaches nor-
mal operating temperature, preferably on a
main road or motorway. The car should then
be driven for approximately 20 minutes
more. When regeneration is complete the
message is cleared automatically.
