PROTECTING THE ENVIRONMENT
The devices for reducing petrol engine emissions are the
following:
❒three-way catalytic converter;
❒Lambda sensors;
❒evaporation prevention system.
In addition, do not let the engine run, even for a test, with
one or more spark plugs disconnected.
The following devices are used for reducing diesel fuel en-
gine emissions:
❒oxidising catalytic converter;
❒exhaust gas recirculation system (EGR);
❒diesel particulate filter (DPF) (for versions/markets
where provided). To close
1) Fit the cap (complete with key) and turn it clockwise
until it clicks once or more.
2) Turn the key clockwise and extract it, then close the
flap.
The hermetic seal may cause a slight increase in pressure
in the tank. A suction noise when you release the cap is
therefore entirely normal.
Do not place naked flames or lit cigarettes
near to the fuel tank opening: fire risk. Keep
your face away from the fuel tank open-
ing to avoid breathing in harmful vapours.

Depress the clutch pedal fully to change
gear correctly. Therefore, the floor area
under the pedals should be clear: ensure that any
rubber mats are flat and do not interfere with the
pedals.
WARNING
Do not drive with your hand resting on the
gear lever, because this pressure, even if
light, can wear out the inner components
of the gearbox over time. The clutch pedal should
be used only for gear changes. Do not drive with
your foot resting on the clutch pedal, however
slightly. For versions/markets where provided, the
electronic clutch control could cut in by interpret-
ing the incorrect driving style as a fault.
SAVING FUEL
Here are some useful tips to save fuel and minimise harm-
ful emissions of CO
2and other pollutants (nitric oxides,
unburnt hydrocarbons, fine dusts etc…).
PRACTICAL ADVICE FOR REDUCING FUEL
CONSUMPTION AND HARMFUL EMISSIONS
Vehicle conditions
1. Have checks and adjustments carried out in
accordance with the “Scheduled Servicing Plan”.
2. Check tyre pressures regularly, at least once every
four weeks. Excessively low pressures will increase
consumption because rolling resistance will be high-
er. In addition, this wears the tyre more quickly and
impairs performance.
3. Only use snow tyreswhen the weather conditions
make them absolutely necessary. They increase con-
sumption and noise.
4. Do not travel with a heavy load: the weight of the
vehicle (especially when driving in town) and its trim
greatly affect fuel consumption and stability.

HEAVY USAGE OF THE VEHICLE
If the vehicle is primarily used in one of the following
particularly onerous conditions:
❒ towing trailers;
❒ dusty roads;
❒ short, repeated journeys (less than 7-8 km) at sub-ze-
ro temperatures;
❒ frequently idling engine or long-distance, low-speed dri-
ving (e.g. door-to-door deliveries) or lengthy inactivi-
ty;
❒ driving in towns and cities;
you should perform the following inspections more fre-
quently than shown on the Scheduled Servicing Plan:
❒ check front disc brake pad conditions and wear;
❒ check cleanliness of bonnet and boot locks, and clean-
liness and lubrication of linkages;
❒ visually inspect the conditions of: engine, gearbox,
transmission, pipes and tubes (exhaust – fuel – brakes),
rubber parts (boots, sleeves, bushes, etc.);
❒ check battery charge and fluid level (electrolite) (check
to be carried out only by specialists or at a Fiat Deal-
ership – see the “Battery” paragraph in this section);
❒ visually inspect the condition of the accessory drive
belts;
❒ check pollen filter and replace, if required;
❒ check and, if necessary, replace air filter.
REGULAR CHECKS
Every 1,000 km or before long journeys, check and, if nec-
essary, top up:
❒ engine coolant fluid level;
❒ brake fluid level;
❒ windscreen washer level;
❒ tyre pressure and conditions.
❒ operation of lighting system (headlights, direction in-
dicators, hazard lights, etc.);
❒ operation of windscreen washer/wipers system and po-
sitioning/wear of windscreen/rear window wiper blades
(for versions/markets where provided);
Check and top up, if required, the engine oil level every
3,000 km.
You are recommended to use
PETRONAS LUBRICANTS
products, which have been designed and produced specif-
ically for Fiat vehicles (see “Capacities” table in the “Tech-
nical specifications” section).

9. Air conditioning leads to higher fuel consumption (on
average up to +30%). If the temperature outside is not
too extreme, try and use the air vents.
Driving style
1. After starting the engineyou should drive away im-
mediately and slowly, avoiding high revs. Do not warm
up the engine at low or high revs when the vehicle is
stationary; this causes the engine to warm up more
slowly, thereby increasing fuel consumption, emissions
and mechanical component wear.
2. Avoid pointless actions such as revving up when at
traffic lights or before stopping the engine. The latter
action, like double-declutching, is unnecessary and caus-
es increased fuel consumption and pollution.
3.Gear selection: select a high gear as soon as possible
(taking into account normal engine operation and traf-
fic conditions) without pushing the engine to high revs
during the intermediate gears. Using low gears at high
revs to get excellent acceleration increases fuel con-
sumption, harmful emissions and engine wear. PRACTICAL ADVICE FOR REDUCING FUEL
CONSUMPTION AND HARMFUL EMISSIONS
Vehicle condition
1. Have checks and servicingcarried out in accordance
with the “Scheduled servicing plan”.
2. Check tyre pressure regularly, at least once every four
weeks. Excessively low pressures will increase con-
sumption because rolling resistance will be higher. In
these conditions, the tyre will wear and performance
will decay faster.
3. Use snow tyresonly when the weather conditions
make them absolutely necessary. They increase con-
sumption and noise.
4. Do not travel with a heavy load: the weight of the
vehicle (especially when driving in town) and its trim
greatly affect fuel consumption and stability.
5. Remove roof racks or ski racksafter use. These ac-
cessories reduce the vehicle’s aerodynamic penetra-
tion and have a negative effect on fuel consumption.
6. It is better to use a trailer to transport particularly bulky
objects.
7. Use the vehicle’s air vents if possible: travelling with the
windows open impairs aerodynamics.
8. Use electrical devices only for the amount of time
needed. The heated rear window, auxiliary headlights,
windscreen wipers and fan heater use up a consider-
able amount of current, causing increased fuel con-
sumption (up to +25% in the urban cycle).
