Always use unleaded petrol. Even a small
amount of leaded petrol can contaminate
the catalyst metals, making the catalytic
converter ineffective.
A defective catalytic converter contributes to
air pollution and can impair your engine’s
performance.
Follow these guidelines to protect your
vehicle’s catalytic converter.
This vehicle is equipped with a catalytic
converter in the muffler to meet the emission
norms.

Keep the engine tuned up.
CATALYTIC CONVERTER
This catalytic converter contains noble metals
that serve as catalyst, promoting chemical
reactions to convert CO and HC in the
exhaust to CO and H O (water vapour).

AIR SUCTION VALVE (ASV)
(SECONDARY AIR INJECTION SYSTEM)
Further to meet emission standards this
vehicle is provided with an air suction valve.
Air suction valve (1) supplies fresh air from
the air filter to the exhaust manifold to convert
carbon monoxide to carbon dioxide. This
reduces the CO% in the vehicle’s exhaust.

This vehicle is equipped with an evaporative
emission control system to meet emission
standards. During warm weather, the petrol

fuel system is unsealed or open. The
evaporative emission control system is used to
prevent petrol vapours from escaping into the
atmosphere from fuel tank. The canister (1)
collects the fuel vapour from the fuel tank and
then the fuel vapour is drawn into the engine
