proportion of harmful substances in the

(CO), hydrocarbons (CH) and nitrous
oxides (N O
x

Control ind icator

Illum inates when the ignition is switched
on a nd during the start attem pt. Goes out
shortly after the eng ine sta rts running.
If it illum inates while the engine is running,
there is a fa ult in the em ission control

may be exceeded. Consult a work shop
immed iately.
Flashing with the engine running indicates
a fault that may damage the catalytic
conv erter. You can continue to drive
without causing damage by slowing down
until the fla shing stop s and the control
