Operation
Preheating (die
sel
en
gines)
When you switch on the ignition, the warning
lamp
lights up. The engine can be started
straight away when the lamp switches off.
If the warning lamp does not illuminate or
if it does not switch off, there is a fault in the
glow plug system.
If the warning lamp starts to flash while
driving, there is a fault in the engine power
control electronic system. The engine control
unit allows driving to continue in an emer-
gency program.
Go to a technical service.
Engine management (petr
ol en-
gines)
If the w
arning lamp is illuminated, there is
a f
au
lt in the engine management system.
The engine control unit allows driving to con-
tinue in an emergency program.
Go to a technical service.
Particulate filter (diesel engines)
The diesel engine particulate filter eliminates
mo
s
t
of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases 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 Diesel 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 in 4th or 5th gear (auto-
matic gearbox: gear S). Maintain the engine
speed at approximately 2,000 rpm. The rise
in temperature causes the soot on the filter
to burn. On completion of the cleaning the
warning lamp will switch off.
If the lamp does not turn off, or the three
lamps turn on (particulate filter , fault in
the emission control system and glow
plugs ), drive the vehicle to a specialised
workshop and have the fault repaired at the
earliest opportunity.
WARNING
●
Alwa
ys drive according to the road weather
conditions, the terrain and traffic.
●
The particulate filter attains very high tem-
peratures. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammab
le materials. Risk of fire!
CAUTION
While the warning lamp i
s lit
up, the fuel
consumption is high, and in certain condi-
tions, the engine power is reduced.
Note
●
In order for the p
articulate 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 pro-
vides information about the countries where
fuel with a high sulphur content is used.
Fuel reserve
The w
arning lamp illuminates when ap-
pr
o
ximately only 7 litres of fuel remain in the
tank
The informative display indicates:
Refuel! Fuel range…km...(miles)
Note
The message on the display switches off only
after r
efuelling and carrying out a short jour-
ney.
