If you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce 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.

For the sake of the environment
Even when the emission control system is

Diesel particulate filter
The diesel particulate filter removes soot par-
ticulates from the exhaust gas, retains and
burns them. To assist the combustion proc-
ess, SEAT recommends you avoid frequent
short trips.
