Diesel engine speed
WARNING
Do not park the vehicle or run the engine in locations where combustible substances
or materials such as grass or leaves can come into contact with the hot exhaust system.
When driving, to avoid damaging the engine, never let the engine speed exceed 4,500
rpm, regardless of which gear is engaged.
If the "Check Anti- Pollution System" message is displayed along with the 
and 
warning lights, consult an approved dealer immediately.
and warning lights, consult an approved dealer immediately.
When driving, depending on the grade of fuel used, it is possible that white smoke
may be emitted.
This is due to the exhaust particle filter being cleaned automatically, and does not
affect the way the vehicle runs.
Running out of fuel
After the tank has been filled following a complete draining of fuel, the fuel system FUEL TANK must be reprimed before starting the engine.
Engine smoke opacity label
You can find the information 1 on the label A affixed in the engine compartment or, depending on the vehicle, on the vehicle identification
plate VEHICLE IDENTIFICATION PLATES.

Precautions to be taken in winter
WARNING
Do not park the vehicle or run the engine in locations where combustible substances
or materials such as grass or leaves can come into contact with the hot exhaust system.
To avoid any faults in icy weather:
- ensure that the battery is always fully charged;
- always keep the diesel tank relatively full to avoid water vapour condensing in it and accumulating at the bottom of the tank.
Particle filter
The particle filter is used in the treatment of exhaust gases from diesel engines.
Depending on the vehicle, the warning light 
displayed on the instrument panel indicates that the filter is becoming clogged and
requires cleaning.
displayed on the instrument panel indicates that the filter is becoming clogged and
requires cleaning.
Note: depending on the vehicle, when the particle filter is operational and does not require
any action by the driver, the "DPF regeneration not needed" message is displayed on the instrument panel to inform them.
Automatic regeneration
To do this, when the warning light is displayed, continue driving according to traffic conditions and
observe the speed limit until the warning lights disappears. If possible, do not let
the engine speed drop below 2,000 rpm.

The warning light should go out after approximately 10 to 20 minutes DISPLAYS AND INDICATORS.
Tip
To facilitate the automatic particle filter regeneration, carry out a long driving
phase (at least 20 minutes) on main roads every 124 miles (200 km).
The display of the warning light on the instrument panel may be accompanied by an increase in engine
speed and operation of the cooling system in order to clean the particle filter.
warning light on the instrument panel may be accompanied by an increase in engine
speed and operation of the cooling system in order to clean the particle filter.
Note: the warning light may reappear if the driving conditions are not fully met with regard
to cleaning the filter. If the vehicle is stopped or the engine speed is below 2,000
rpm before the warning light is switched off you may have to restart the operation.
Manual regeneration
(depending on the vehicle)
WARNING
Do not start the regeneration in a garage or a confined area.
Risk of poisoning or suffocation by exhaust gas emissions.
Make sure that no one is near the exhaust when regenerating.
Risk of burns.
Do not park the vehicle in locations where combustible substances or materials such
as grass, leaves or paper may come into contact with or be near to the hot exhaust
system.
Fire hazard.
Do not leave your vehicle unsupervised during regeneration.
If it is not possible to comply with the conditions (driving time required, etc.),
the warning light displayed on the instrument panel comes on, accompanied by the message " Regenerate the particle filter " to indicate that the saturation level is too high for automatic regeneration.
light displayed on the instrument panel comes on, accompanied by the message " Regenerate the particle filter " to indicate that the saturation level is too high for automatic regeneration.
You must quickly carry out manual regeneration to avoid saturation of the particle
filter which may require you to consult an approved dealer.
Manual regeneration of the particle filter leads to high temperature in the exhaust
system and exhaust gases. Precautions must be taken into account during the process
which lasts for approximately 40 minutes.
To do this, when the warning light comes on, accompanied by the message " Regenerate the particle filter ":
comes on, accompanied by the message " Regenerate the particle filter ":
- park your vehicle off the road, away from traffic and in a place where it is at least three metres from any obstacles or material which could easily ignite or melt (e.g. paper, grass, plastic, dry organic material, etc.);
- apply the parking brake;
- Set the gear lever to neutral (position N on vehicles with an automatic gearbox).
Then, with the engine on:
- deactivate the Stop and StartSTOP AND START FUNCTION function (if the vehicle is equipped);
- go to the "Vehicle" tab in the instrument panel menu TRIP COMPUTER;
- press button 3 or 4 repeatedly until the "Regenerate DPF [long press]" message appears;
- press and hold button 2 until the "DPF regeneration Ongoing" or "Regen 40min-to stop press brake" message appears. The warning light flashes.
Wait until the warning light goes out (approximately 40 minutes). The "DPF Regeneration Completed" message is displayed on the instrument panel.
If the conditions are not met before or during regeneration, the warning light goes out and the message " DPF Regeneration Interrupted " is displayed and the procedure is cancelled.
goes out and the message " DPF Regeneration Interrupted " is displayed and the procedure is cancelled.
The "Regenerate DPF [long press]" message will be displayed as soon as the conditions required to renew the manual
procedure are once again met.
Note: do not start the regeneration in the event of an insufficient oil or coolant level
(oil pressure warning light 
or coolant temperature warning light 
lit on the instrument panel). In this case, top up ENGINE OIL and LEVELS, FILTERS.
or coolant temperature warning light lit on the instrument panel). In this case, top up ENGINE OIL and LEVELS, FILTERS.
Regeneration is not possible:
- if the fuel level is too low;
- if the engine is too cold;
- in extreme weather conditions (cold, hot or very high altitude).
During the regeneration process:
- the engine speed first increases to approximately 3,000 rpm in order to warm the engine. It then decreases to approximately 2,000 rpm until the end of the regeneration;
- the fan assemblies are triggered. This is a normal operation to ensure engine cooling;
- white fumes and unusual odours are frequently produced in the exhaust system. This does not indicate that the system is operating incorrectly.
If you need to interrupt the particle filter regeneration, press one of the pedals. In this case, regeneration will only be partial.
Special cases
WARNING
For your own safety, the 
warning light requires you to stop immediately, as soon as traffic conditions allow.
Switch off the engine and do not restart it. Call an approved dealer.
