Controlling exha ust emission
Through design-related measures - mainly
in the a rea of the mixture formation
system - the proportion of noxious
materials in the exhaust, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO
x
), is reduced to a
minimum.
Control ind icator Z for exhaust
Illum inates when the ignition is switched on
and during the start attempt. Extinguishes
shortly after the engine starts running.
If it illuminates while the engine is running
there is a fault in the emission control
sy ste m. T he pe r mit ted emis sio n v a lu es may
be exceed ed. Consult a work shop
immed iately.
C ont rol indic ator A for eng ine
electronics
Illuminates for a few seconds when ignition
is switched on.
If the control indicator A illuminates when
the engine is running, there is a fault in the
engine electronics. The electronics switch
to the emergency running programme, fuel
consumption may increase and the
driveability of the vehicle may be affected.
In some cases the fault can be eliminated
by sw itching the engine off and back on
again. If the control indicator A
illuminates again when the engine is
running, consult a workshop to have the
cause of the fault eliminated.
