PROTECTING THE ENVIRONMENT
The 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.
It is needed to eliminate almost all particulates in
compliance with current/future legislation. During
normal use of the vehicle, the engine control unit
records a set of data (e.g.: travel time, type of route,
temperatures, etc.) and it will then calculate how
much particulate has been trapped by the filter.
Since this filter physically traps particulate, it should
be regenerated (cleaned) at regular intervals by
burning the carbon particles. The regeneration
procedure is controlled 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.

CHANGING A BULB
GENERAL 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
sys
tem 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
w
hich may cause small fragments of
glass to be projected outwards if the bulb is
broken.
Halogen bulbs must be handled holding
the metallic part only.Touching the
transparent part of the bulb with your
fingers may reduce the intensity of the emitted
light and even reduce the lifespan of the bulb.
If you do touch it accidentally, rub the bulb with
an alcohol-soaked cloth and leave to dry.
If possible, we recommend have bulbs
replaced by a Fiat Dealership. Proper
operation and orientation of the external
lights are essential for the safety of the running
vehicle, and to avoid incurring legal sanctions.
IMPORTANT The internal surface of the light may
appear slightly misty: this does not indicate a fault,
and is actually caused by low temperature and the
degree of humidity in the air. Misting will rapidly
disappear when the headlights are switched on. The
presence of drops inside the headlights indicates
infiltration of water. Go to a Fiat Dealership.

❒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
en
gine compartment : inflammable gases
and vapours may be present , constituting a fire
risk.
