If you experience misfiring, a significant
loss of engine power or other unusual
problems, seek assistance from a
workshop as soon as possible. If
necessary, continue driving for a short
time at slow speeds, keeping the engine
revs low.

into action are the result of operating
conditions and are therefore of no
significance – see page 166.
Controlling exhaust emission
Design measures, primarily in the fuel
injection system and ignition system zones
in combination with the catalytic converter,
the amount of hazardous substances in the
exhaust emissions, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO
x
), are reduced to a
minimum.
Control indicator
Z
for exhaust
Illuminates when the ignition is switched on
and during the start attempt. Extinguishes
shortly after the engine starts running.
Illumination whilst the engine is running
indicates a fault in the emission control
system. The permissible emission limits
may be exceeded. Contact a workshop for
assistance immediately.
Flashing with the engine running indicates
a fault that can cause damage to the
catalytic converter. It is possible to
continue driving without causing damage
by slowing down until the flashing stops
and the control indicator illuminates.
Contact a workshop for assistance
immediately.
