Driving Tips - Seat Toledo 2019 Owner's Manual

For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the exhaust gas under some
conditions. This depends on the sulphur
content of the fuel used. Quite often the
problem can be solved by changing to an-
other brand of fuel.
Particulate filter
3 Applies to vehicles with diesel engine
The diesel engine particulate filter eliminates
most of the soot from the exhaust gas system.
Under normal driving conditions, the filter
cleans itself. The particulate filter is cleaned
automatically without need for indication by
the warning lamp . This may be noticed

because the engine idle speed increases and
an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the particulate filter warning lamp will
switch on.

Facilitate the automatic filter cleaning proc-
ess by driving in the following manner:
Drive for approximately 15 minutes at a
●
minimum speed of 60 km/h (37 mph) in 4th or
5th gear (automatic gearbox: S gear range).
214
Driving
Maintain the engine speed at approximate-
●
ly 2,000 rpm.
The rise in temperature causes the soot on
the filter to burn. On completion of the clean-
ing the warning lamp will switch off. If the
warning lamp does not switch off, go immedi-
ately to a specialised workshop to rectify the
problem.
CAUTION
While the warning lamp is lit up, the fuel

consumption is high, and in certain condi-
tions, the engine power is reduced.
Note
In order for the particulate filter to burn
●
off soot in a correct manner, avoid carrying
out frequent short journeys.
Using diesel fuel with a high sulphur
●
count can considerably reduce the useful
life of the particulate filter. The specialised
service provides information about the
countries where fuel with a high sulphur
content is used.

Driving tips

Driving through flooded roads
Driving through water.
Fig. 220
To prevent the vehicle from being damaged
when driving through water (i.e. flooded
roads), please observe the following:
Determine the depth of the water before
●
entering. Water can reach a maximum height
›››
of below the door sill Fig. 220.
Drive at a maximum pace of walking speed.
●
Driving at a higher speed can cause a wave
in front of the vehicle, which can cause water
to enter the engine air intake system or other
parts of the vehicle.
Never stop in the water, never reverse and
●
never stop the engine.
Before driving through water deactivate the
