Always use unleaded petrol. Even a small
amount of leaded petrol can contaminate
the catalyst metals, making the catalytic
converter ineffective.

Keep the engine tuned up.
Follow these guidelines to protect your
vehicle’s catalytic converter.
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 vehicles’s exhaust.
This vehicle is equipped with an evaporative
emission control system to meet emission
standards. During warm weather, the petrol
vapours which contain HC evaporates easily
into the atmosphere from the fuel tank, if the
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
for re-burning to avoid pollution caused by
the fuel vapour diffused into the air.
