Driving and operating
Catalytic converter
Controlling exhaust emission
The catalytic converter reduces to a
minimum the proportion of noxious
materials in the exhaust, such as
carbon monoxide (CO),
hydrocarbons (CH) and nitrogen
oxides (NO
x
).
Leaded fuel will damage the catalytic
converter and parts of the electronic
system, thereby rendering them
inoperative.
If the engine misfires or runs
roughly after a cold start, the
engine power has reduced
significantly or other unusual
operating problems occur that
indicate a fault in the ignition
system, seek the assistance of a
workshop as quickly as possible.
Drive at a slower speed and with
less engine revs for a short time, if
necessary.
If unburned fuel enters the catalytic
converter, this may result in
overheating and irreparable
damage to the catalytic converter.
You should therefore avoid
frequent cold starts, unnecessarily
long use of the starter when setting
off, running the tank dry (an
irregular fuel supply leads to
overheating) and starting the
engine by pushing or towing.
If the control indicator for exhaust
emissions
Z
illuminates whilst
driving, seek the assistance of a
workshop immediately. Control

Exhaust gases
Caution
Damage to the catalytic converter or
the vehicle may result if the following
points are not observed.

Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which has no colour or odour and
can be lethal if inhaled.
If exhaust fumes penetrate the
vehicle interior, open the windows
and seek the assistance of a
workshop immediately.
