The perfect functioning of the clean-
ing system for exhaust fumes
is of
great importance for the environment-
friendly functioning of your vehicle.
Therefore, keep in mind the following
points:
•
Versions with a catalytic converter must
only use unleaded fuel. See the "Filling the
tank" chapter.
•
In vehicles with a catalytic converter
never drive until the fuel tank becomes
completely empty. Irregular fuel supply
can cause misfiring, thus allowing
unburned fuel into the exhaust system
which can cause overheating and damage
to the catalyst.
•
Starting difficulties, loss of power, or
uneven engine revolution experienced
while driving could be caused by a defect
in the ignition system. In this case, fuel
may be entering the exhaust system with-
out burning and, in this way being
released into the atmosphere. Further-
more, the catalyst could deteriorate due
to overheating. Decrease speed immedi-
ately and head to the nearest Technical
Service Centre to fix the failure.
•
Do not overload the engine with oil. See
the chapter "Checking the oil".
•
Do not towstart the vehicle for more
than 50 m. See the chapter "Tow start/
towing".
Warning
•
Due to possible high tempera-
tures of the catalyst, do not park in
places where the catalyst is easily
exposed to inflammable material.
•
Do not use additional protection
for the body or anticorrosive prod-
ucts for sumps and exhaust pipes,
catalytic converters or heat shields.
The above mentioned material
could ignite while driving.
Note
Even when the cleaning system for
exhaust fumes is in perfect working order,
under certain circumstances, the fumes
may smell like sulfur.
This depends on the percentage of sulfur
in the fuel.
Often it is sufficient to change brand or
buy super unleaded.
