Vehicle care 191
Owner responsibility
The engine, engine control system
and exhaust system of the vehicle
must not be modified in any way.
Warning
Any person who removes,
modifies or hinders any part of the
emission control system may be
contravening Australian Design
Rules. It is also illegal to drive a
vehicle modified in this way.
First drive
When the vehicle is driven for the
first time, wax and oil on the exhaust
system may evaporate, producing
smoke-like emissions that should
not be inhaled. Allow wax and oil to
evaporate while the vehicle is in the
open air.
Maintenance requirements
Have the vehicle serviced at the
frequency shown in the Maintenance
schedule, in the Service/Warranty
Booklet.
It is recommended that servicing
be carried out by an authorised
Holden Dealer who will maintain the
vehicle’s emission control system as
per the Service/Warranty Booklet.
Diesel engine
Diesel particle filter (DPF)
The diesel particle filter system
collects particulates from the
exhaust gases to minimise discharge
of soot to the atmosphere.
To prevent clogging of the filter, the
soot particles are burnt off at regular
intervals through a self cleaning
process where additional fuel is
injected into the engine cylinders
to increase the particle filter
temperature to approximately 600°C.
This allows deposited soot to be
oxidized or burnt off to carbon
dioxide (CO
2
).
This process usually takes between
10 and 12 minutes but may take up
to 25 minutes depending on driving
conditions.
Increased engine speed at idle,
operation of engine cooling fan and
emissions of odours and smoke are
considered to be normal conditions
during the self cleaning process.
Fuel consumption may also be
higher during this period.
Under certain driving conditions,
e.g. when operated for prolonged
periods at low engine loads,
the system cannot clean itself
automatically.
If the cleaning of the filter is required
and if previous driving conditions
did not enable automatic cleaning,
it will be indicated by the control
indicator .
