Emission control

systems
Catalytic converter
Applies to vehicles with petrol engine:
cle must only be used with unleaded petrol; oth­
erwise the catalytic converter will be irreparably
damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­
ing. This allows unburnt fuel to enter the exhaust
system, which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine:
sel particulate filter can filter out almost all soot
particles contained in the exhaust gas. In normal
driving conditions the filter is self-cleaning.
236
Should the self-cleaning function of the filter not
be able to operate, e.g. when the vehicle is con­
tinuously used only for short trips, the filter be­
comes obstructed with soot and the symbol
for the diesel particulate filter lights up
qpage 15.

WARNING
The exhaust system is very hot when the vehi­
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission control system (cata­
lytic converter or diesel particulate filter),
do not park the vehicle where the exhaust
can come into contact with flammable ma­
terials under the car (e.g. on grass or at the
forest edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of
fire!
