Start and driving
It lights up
Fault in the management of the petrol engine.
Have the engine checked by a specialised w
orkshop
as soon as possible.
The warning lamp (Electronic P
ower Control)
lights up when the ignition is switched on while sys-
tem operation is being verified. It should go out once
the engine is started.
It lights up
Diesel engine glow plug system.
The engine glow plug syst
em has been activated.
The engine can be started straight away when the
lamp switches off.
Flashes
Fault in the management of the diesel engine.
Have the engine checked by a specialised w
orkshop
as soon as possible.
Note
While the control lamps are on , ,
or there might be faults in the engine
,
fuel consumption may go up and the en-
gine might lose power.
Catalytic converter
To maintain the useful life of the catalytic
convert
er
●
Use only unleaded petrol with petrol en-
gines, as lead damages the catalytic con-
verter.
●
Do not let the fuel get too low in the tank.
●
For engine oil changes, do not replenish
with too much engine oil

page 305, Top-
ping up engine oil.
●
Never tow the vehicle to start it, use jump
leads if necessary

If you notice misfiring, uneven running or loss
of power when the vehicle is moving, reduce
speed immediately and have the vehicle in-
spected at the nearest specialised workshop.
In general, the exhaust warning lamp will
light up when any of the described symptoms
occur. If this happens, unburnt fuel can enter
the exhaust system and escape into the envi-
ronment. The catalytic converter can also be
damaged by overheating.
CAUTION
Never run the fuel tank completely dry be-
cause the irregularit
y of the fuel supply
may cause ignition problems. This allows
unburnt fuel to enter the exhaust system,
which could cause overheating and dam-
age the catalytic converter.
For the sake of the environment
Even when the emission control system is
working perfectly, ther
e 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
The particulate filter eliminates most of the
soot fr
om the e
xhaust gas syst
em. Under nor-
mal 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).
