191 Driving and operation
z If the control indicator Z for exhaust
gases flashes, slow down until the
flashing stops and the control indicator
illuminates. Contact a workshop for
assistance immediately. Control
indicator Z for exhaust gases – see
page 192.
Catalytic converter for diesel engines
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed:
z On uneven running, a clear drop-off in
engine power or other unusual operating
symptoms, contact a workshop
immediately. Continue driving if
necessary for a short time at low speed
and low revs.
Irregular engine running and a loss of
engine power when the Electronic
Stability Program (ESP®
Plus
3 ) comes
into action are the result of operating
conditions and are therefore of no
significance – see page 196.
Controlling exhaust emission
Some of the damaging substances in
the exhaust such as carbon monoxide (CO),
hydrocarbons (HC) and nitrous
oxides (NO
x
) are reduced to a minimum
by making structural changes – mainly in
the injection system and the ignition system
in conjunction with the catalytic converter.
