CAUTION

Fault in the emission control system.

Reduce speed and drive carefully to the nearest speci-

alised workshop to have the engine checked.

Never run the fuel tank completely dry be-

cause an irregular fuel supply can cause ig-

nition faults. This allows unburnt fuel to en-

ter the exhaust system, which could cause

overheating and damage the catalytic con-

verter.

Note

While the control lamps , ,  or  are

on, there might be faults in the engine, fuel

consumption may go up and the engine

might lose power.

Combustion failures that can damage the catalytic

converter.

Reduce speed and drive carefully to the nearest speci-

alised workshop to have the engine checked.

For the sake of the environment

Even when the emission control system is

working perfectly, there may be a smell of

sulphur from the gases on occasions. This

depends on the sulphur content of the fuel

used. This can quite often be avoided by

changing to another brand of fuel.

The particulate filter eliminates most of the

soot from the exhaust gas system. Under

normal driving conditions the filter cleans it-

self. If the filter does not clean itself (e.g. if

short journeys are made continuously), it be-

If you should notice misfiring, uneven run-

ning or loss of power when the car is moving,

have the vehicle inspected by a specialised

workshop. In general, the emissions warning

lamp  will light up when any of these symp-

toms occur. If this happens, any unburnt fuel

can enter the exhaust system and escape in-

The engine can be started straight away when the lamp
