WARNING
The components of the exhaust system
reach very high temperatures. This could
cause a fire.
Always park your vehicle so that no part
●
of the exhaust system can come in contact
with flammable materials (such as dried
grass).
Never apply additional underseal or anti-
●
corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on
the exhaust system.

quent treatment of the exhaust gases thus re-
ducing contaminating gas emissions. To en-

If you should notice misfiring, uneven running
or loss of power when the car is moving, re-
duce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating.
