Cleaning t t he e e xhaust f f umes
The p p erfect f f unctioning o o f t t he c c lean-
ing s s ystem f f or e e xhaust f f umes 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 "Filling the
tank".
•
In vehicles with a catalytic converter
never drive until the fuel tank is com-
pletely empty. Irregular fuel supply can
cause misfiring, thus allowing unburned
fuel into the exhaust system which can
cause overheating and damage to the cat-
alyst.
•
If while driving you experience starting
difficulties, loss of power or engine prob-
lems the cause could be a failure in the
ignition. In this case, fuel may have
entered the exhaust system without burn-
ing and may be released to the atmos-
phere. In addition, the catalyst can deteri-
orate due to overheating. Speed needs to
be decreased immediately. See the near-
est Technical Service Centre to fix the fail-
ure.
•
Do not fill the engine with too much oil.
See "Checking oil level".
•
Do not tow vehicles for more than 50 m
when trying to tow start. See "Tow
stat/starting" chapter.

Note
Even when the filtering system for
exhaust fumes is in perfect working order,
under certain circumstances, the fumes
may smell like sulphur.
This depends on the percentage of sulfur
in the fuel.
Often it is sufficient to change brands or
buy super unleaded.
