128GETTING THE BEST OUT OF YOUR VEHICLE
LOOKING AFTER EMISSION
CONTROL DEVICES
The correct use of pollution control
devices not only ensures respect for
the environment but also has an effect
on the vehicle’s performance.
Keeping these devices in good con-
ditions is therefore a fundamental rule
for driving that is easy on your pock-
et and on the environment too.
The first step to take is to follow the
Service Schedule to the letter.
If your vehicle has a petrol engine
with catalytic converter use only un-
leaded petrol.
if you have trouble starting, do not
keep turning the ignition key for long
periods. Be especially careful to avoid
bump starting the vehicle by pushing,
towing or rolling downhill: these are
all manoeuvres that can damage the
catalyst.
Use an auxiliary battery for start-ups
only.If the engine begins to “loose its
smoothness” when travelling, contin-
ue your journey but reduce the de-
mands you are making on the engine
and have the vehicle seen to at a Fi-
at Dealershipas soon as you can.
When the instrument panel fuel re-
serve warning light comes on, fill up as
soon as possible. A low fuel level may
cause an uneven supply of fuel to the
engine with inevitable increase in the
temperature of the exhaust gas and se-
rious damage to the catalytic con-
verter.
Never run the engine with one or
more spark plugs disconnected, even
for testing purposes.
Do not warm up the engine by let-
ting it idle for a while before moving
off unless the outside temperature is
very low and, even in this case, only
do so for less than thirty seconds.
Do not install heat shields and do not
remove those already fitted to the cat-
alytic converter and exhaust pipe.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda sensor and
exhaust pipe.
WARNING
Ignoring the above rules
may lead to fire.
WARNING
When functioning normal-
ly the catalytic converter
reaches high temperatures. For this
reason do not park the vehicle over
inflammable material (grass, dry
leaves, pine needles, etc.): fire haz-
ard.

FUEL SUPPLY/IGNITION
Petrol version
Electronic Multipoint sequential
phased integrated electronic injection
and ignition; a single injection system
controls both functions. It processes
both the time the injection lasts (for
fuel metering) and the ignition advance
angle.FUEL SUPPLY
JTD/JTD POWER versions
UNIJET (Common Rail) electronic
control direct injection, turbosuper-
charger with WASTEGATE valve and
intercooler (2.3 JTD, 2.8 JTD and 2.8
JTD POWER versions).SPARK PLUGS
The cleanness and soundness of the
spark plugs are very important for
keeping the engine efficient and pol-
luting emissions down.
The appearance of the spark plug, if
examined by an expert eyes, is a good
way of pinpointing a problem even if it
has nothing to do with the ignition sys-
tem. Therefore, if the engine has prob-
lems, it is important to have the spark
plugs checked at a Fiat Dealership.
The spark plugs must be
changed at the times
specified in the
SERVICE
SCHEDULE
. Only use the type of
plugs indicated: if the heat ratio
is less than required or the life
specified is not guaranteed, prob-
lems can arise.
Modifications or repairs to
the fuel feed 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.

FUEL CONSUMPTION - CO2EMISSIONS
RUNNING AND USE CONDITIONS AFFECTING FUEL CONSUMPTION
(examples and differences with respect to goods transportation vehicle data)
IMPORTANT
Although fuel consumption mea-
surements procedure aim at defining
realistic values, fuel consumption is in-
fluenced by factors such as:
Driving style and vehicle usehigh
speed, frequent acceleration, frequent
gear shifting, door-to-door deliveries,
etc.
Just for passenger transportation
versions with 2.3 and 2.8 JTD engines,
reduced consumption can be obtained
by starting (on level road) in 2nd gear
instead of 1st gear.
Traffic and road conditions
queues, bending roads, steep roads,
bad road surface, etc.Weather conditions and tem-
peratures
low temperatures, thinner air, wind,
rain etc…;
Vehicle conditions
Poor maintenance (tyre pressure, fil-
ters, spark plugs, etc.), damaged body-
work
Load conditions
Heavy weights, not optimal load dis-
tribution, large weights on roof rack,
etc.
Use of electric devices
Climate control, heater and electric
devices in general
Special conditions of use
Special vehicle conditions of use: roof
rack, trailer, open side windows, type
of tyres, etc.Special trim and adaptations
caravan, motor home, mega box, can-
vas cover, etc.
Some of these conditions are illus-
trated in these figures on the next
pages.
For more information, refer to the
advice in the chapter “Cheap running
that respects the environment.
The fuel consumption values shown
in the table in following pages were de-
fined according to the type-approval
specifications in European Directives.
Consumption values are defined by
means of the following procedures:
– an urban cycle: consisting of a
cold start and a simulated drive in city
streets;
– an extra-urban cycle: consisting
in frequent accelerations, in all gears,
