FUEL
The vehicle is fitted with emission control systems, which 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. Hydrocarbons
and oxides of nitrogen, when exposed to sunlight under certain conditions, contribute
to photochemical smog. In addition, carbon monoxide is toxic when it becomes highly
concentrated in the air.
The three major emission control systems that may be fitted to the vehicle 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 is comprised
of components including electronic control of spark, fuel and idle speed. In addition
vehicles have a catalytic converter and closed loop mixture control system.
Note For service and repair to the vehicles fuel or emission systems contact your
Holden Dealer.
oWnER RESPonSIBILITy
The engine, engine control system and exhaust system of the vehicle must NOT
be modified in any way. Any change to the design may increase the emissions or
otherwise defeat the intent of the regulations.
WARNINg
Any person who removes, modifies or hinders any part of the emission control system
may be contravening Australian Design Rules, refer A.D.R. 83/00 (External Noise for
Motor Vehicles) and A.D.R. 79/01 (Emission Control for Light Vehicles, 'Euro 3'). It is
also illegal to drive a vehicle modified in this way.
mAInTEnAnCE REquIREmEnTS
To ensure continuing compliance with the regulations, you must have the vehicle
serviced at the frequency shown in the Maintenance schedule, in the Service/warranty
booklet. Your Holden Dealer will maintain the vehicle's emission control system as per
the vehicle's service manual.
It is recommended that the necessary servicing be performed by an authorised Holden
Dealer who has the specialised servicing equipment and trained personnel available to
ensure that the adjustments and services specified are carried out.
