PROTECTING THE ENVIRONMENTThe following devices are used for reducing diesel
fuel engine emissions:
❒oxidising catalytic converter
❒exhaust gas recirculation system (EGR)
❒diesel particulate filter (DPF) (for versions/
markets, where provided).
DIESEL PARTICULATE FILTER (DPF)
(for versions/markets, where provided)
The Diesel Particulate Filter is a mechanical filter,
integral to the exhaust system, that physically traps
carbon particulates present in the exhaust gases
of diesel engines.
The diesel particulate filter has been adopted to
eliminate almost all particulates in compliance with
current/future regulations.
During normal use of the vehicle, the engine
management control unit records a set of data
(travel time, type of route, temperatures reached
etc.) and calculates how much particulate has been
trapped by the filter.Since this filter physically traps particulate, it must be
regenerated (cleaned) at regular intervals by burning
the carbon particles.
The regeneration procedure is managed
automatically by the engine management control unit
according to the filter conditions and vehicle use
conditions.
During regeneration, the following may occur: a
limited increase in the engine speed, activation of the
fan, a limited increase in fumes and high
temperatures at the exhaust.
These are not faults; they do not impair vehicle
performance or damage the environment. If
the dedicated message is displayed, refer to the
“Warning lights and messages” section.

❒connect B to the canister and fit the filler tube A
into its allocated space.
CHANGING A BULBGENERAL INSTRUCTIONS
❒Before changing a bulb check the contacts for
oxidation;
❒burnt bulbs must be replaced by others of the
same type and power;
❒always check the height of the headlight beam after
changing a bulb, for reasons of safety;
❒when a light is not working, check that the
corresponding fuse is intact before changing the
bulb. For the location of fuses, refer to the
“Changing a fuse” paragraph in this section;
WARNING
Modifications or repairs to the electrical
system that are not carried out
properly or do not take the system's technical
specifications into account can cause
malfunctions leading to the risk of fire.
WARNING
Halogen bulbs contain pressurised gas
which may cause small fragments of
glass to be projected outwards if the bulb is
broken.

❒visually inspect conditions of: engine, gearbox,
transmission, pipes and hoses (exhaust - fuel
system - brakes) and rubber elements (boots -
sleeves - bushes - etc.);
❒check battery charge status and fluid (electrolyte)
level (refer to "Battery - Check state of charge
and electrolyte level" paragraph in this chapter);
❒visually inspect condition of the auxiliary drive
belts;
❒check and, if necessary, replace pollen filter, in
particular it should be replaced if there is a
noticeable decrease in the passenger compartment
air intake flow rate.
❒check and, if necessary, replace air filter.
CHECKING LEVELS
When topping up, take care not to mix up
the various types of fluids: they are not
compatible with each other and could
seriously damage the vehicle.
WARNING
Never smoke while working in the
engine compar tment : inflammable gases
and vapours may be present , constituting a fire
risk.
