Vehicle care 173
General information
Where specied, use only Holden
genuine parts and accessories.
Emission information
The emission control systems are
designed to reduce the amount
of hydrocarbons (HC), carbon
monoxide (CO), and oxides of
nitrogen (NOx) that are emitted
from the engine and fuel system
into the atmosphere. HC and NOx,
when exposed to sunlight under
certain conditions, contribute to
photochemical smog. In addition,
CO is toxic when it becomes highly
concentrated in the air.
Emission control system
Major emission control systems the
vehicle may have are:
1. Evaporative emission control
system. This system is designed
to prevent the escape of fuel
vapour from the fuel system and
recycle the vapours through the
normal combustion process.
2. Crankcase emission control
system. This system is designed
to prevent blow-by gases from
escaping into the atmosphere
and recycle them through the
combustion process.
3. Exhaust emission control system.
The various components of
this system operate collectively
to limit HC, CO and NOx
emissions in the exhaust gas.
The exhaust emission control
system consists of components
including electronic control of
spark, fuel and idle speed. In
addition vehicles have a catalytic
converter and closed loop
mixture control system.
It is recommended that service and
repair to fuel or emission systems
be carried out by a Holden Dealer.
Owner responsibility
The engine, engine control system
and exhaust system of the vehicle
must NOT be modied in any way.
Warning
Any person who removes,
modies or hinders any part of the
emission control system may be
contravening Australian Design
Rules. It is also illegal to drive a
vehicle modied in this way.
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 a Holden Dealer
who will maintain the vehicle’s
emission control system as per the
Service & Warranty Booklet.
