Hot exhaust system
Warning
High temperatures can occur underneath the
body, for instance caused by the exhaust
system, while driving. Contact with the ex-
haust system can cause burns. There is a
risk of injury. Do not touch the hot exhaust
system, including the exhaust pipe.
Warning
If combustible materials, such as leaves or
grass, come in contact with hot parts of the
exhaust system, these materials can ignite.
There is a risk of fire and an injury hazard.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in
contact with hot vehicle parts while driving, in
Neutral or during parking.
Exhaust gas particulate filter
Principle
The exhaust gas particulate filter collects soot
particles. The soot particles are burned at high
temperatures to clean the exhaust gas particu-
late filter as necessary.
