If the needle reaches the red
area, stop the engine immedi-

ENGINE COOLANT
TEMPERATURE GAUGE
This shows the temperature of the engine
coolant fluid and begins working when the
fluid temperature exceeds approx. 50°C.
Under normal conditions, the needle
should move to different positions of the
scale according to the conditions of use
of the car.
C- Low engine coolant temperature.
H- High engine coolant temperature.The turning on of the warning light B-fig.
19(together with the message shown on
the display) indicates that the coolant flu-
id temperature is too high; in this case,
stop the engine and contact a Fiat Deal-
ership. FUEL LEVEL GAUGE
This shows the amount of fuel left in the
fuel tank.
The reserve warning light A-fig. 19turns
on to indicate that approx. 8-10 litres of
fuel are left in the tank.
E- tank empty.
F- tank full (see contents of “At the filling
station” paragraph in this chapter).
Do not travel with the tank almost emp-
ty because the catalytic converter could
become damaged.
IMPORTANT The needle sets to Ewith
warning light Aflashing to indicate that the
system is failing. In this event contact Fiat
Dealership to have the system checked.

DASHBOARD
AND CONTROLS
During normal service the
catalyst and the diesel par-
ticulate filter (DPF) reach high tem-
peratures. Do not therefore park the
car over inflammable materials (grass,
dry leaves, pine needles, etc.): fire
hazard.
WARNING
Diesel Particulate Filter clogged
If the warning light hon the instru-
ment panel turns on (together with the
message on the display) refer to section
“Warning lights and messages”. DIESEL PARTICULATE FILTER
(DPF)
(for versions/markets, where
provided)
The Diesel Particulate Filter is a mechan-
ical filter, integral with the exhaust system,
that physically traps particulate present
in the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates
in compliance with current / future law
regulations.
During normal use of the car, 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
particulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular
intervals by burning carbon particles. Re-
claiming procedure is controlled auto-
matically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the car.
During reclaiming the following phenom-
ena could take place: idling slight increase,
fan activation, slight smoke increase, high
exhaust temperatures. These situations
shall not be considered as faults and they
do not affect car performance and envi-
ronment.
PROTECTING
THE ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒three-way catalytic converter;
❒Lambda sensor;
❒fuel evaporation system.
In addition, do not let the engine run, even
for a test, with one or more spark plugs
disconnected.
The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒Lambda sensors;
❒diesel particulate filter (DPF) (for ver-
sions/markets, where provided it is fit-
ted instead of the Lambda sensor).
