Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
WARNING
Observe traffic regulations when cleaning the
diesel particulate filter while driving.
Driving
Only carry on driving if visibility, weather,
●
road and traffic conditions so permit.
● Never endanger your safety or that of other
road users.
CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle.
Note
While the control lamps , ,  or  re-
main lit, there may be engine problems, fuel
consumption may increase and the engine
may lose power.
Catalytic converter
The catalytic converter permits the subse-
quent treatment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
Always use unleaded petrol.

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
working perfectly, there may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel be-
ing used.
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.
● Always use diesel with a low sulphur con-
