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.

INDEXHANDBRAKE
The handbrake is located between the two front seats.
Pull the lever upwards to engage the handbrake and en-
sure that the vehicle does not move.
STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a long drive, you should allow the
engine to “catch its breath” before turning it off by let-
ting it idle to allow the temperature in the engine com-
partment to fall.
Never jump start the engine by pushing,
towing or driving downhill. This could cause
fuel to flow into the catalytic converter and
damage it beyond repair.
The vehicle should be secured after sev-
eral clicks of the lever. If it is not, contact
a FIAT Dealership to have it adjusted.
WARNING
When the handbrake is on and the ignition key is at MAR,
the instrument panel warning light
xwill come on.
Proceed as follows to release the handbrake:
❒lift the lever slightly and press release button A-fig. 126;
❒hold button A down and lower the lever. The xwarn-
ing light on the instrument panel will go out.
Depress the brake pedal when carrying out this opera-
tion to prevent the vehicle from moving accidentally.

INDEXDepress 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.

INDEX2. 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
causes increased fuel consumption and pollution.
3.Gear selection: select a high gear as soon as possi-
ble (taking into account normal engine operation and
traffic conditions) without pushing the engine to high
revs during the intermediate gears. Using low gears
at high revs to get lively acceleration increases fuel
consumption, harmful emissions and engine wear.
4.Vehicle speed: fuel consumption increases expo-
nentially as the speed of the vehicle increases. Keep
your speed moderate and as even as possible, avoid-
ing unnecessary braking and acceleration, which
cause excessive fuel consumption and increased
emissions. Keeping a safe distance from the vehicle in
front helps to maintain a steady speed.
5.Acceleration: accelerating violently severely affects
consumption and emissions. Acceleration should be
gradual and should not exceed the maximum engine
torque rate. 5. Remove roof racks or ski racksafter use. These
accessories reduce the vehicle’s aerodynamic pene-
tration and have a negative effect on fuel consump-
tion.
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 the aerodynamics.
8. Only use electrical devices for the amount of time
needed. The heated rear window, auxiliary head-
lights, windscreen wipers and fan heater use up
a considerable amount of current, causing increased
fuel consumption (up to +25% in the urban cycle).
9. Using the climate control leads to higher fuel con-
sumption (on average up to +30%). If the tempera-
ture outside is not too extreme, try and use the air
vents.
Driving style
1. After starting the engineyou should drive away
immediately 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.

INDEXTOWING TRAILERS
IMPORTANT NOTES
The vehicle must be provided with a type-approved tow
hitch and adequate electrical system to tow trailers. In-
stallation must be performed by specialised personnel who
will issue the required papers for travelling on roads.
Install any specific and/or additional rear-view mirrors in
accordance with the highway code of the country in which
you are travelling.
Remember that when towing a trailer, steep hills are hard-
er to climb, braking distances increase and overtaking takes
longer depending on the overall weight of the trailer.
Engage a low gear when driving downhill, rather than con-
stantly using the brake.
The weight of the trailer on the vehicle tow hitch will re-
duce the loading capacity of the vehicle by the same
amount.
Consider the weight at full load, including accessories and
luggage, to make sure you do not exceed the maximum
towable weight (shown in the log book).
Respect each country’s speed limits for vehicles towing
trailers. In all cases, the top speed must not exceed
80 km/h. CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups prevent the
engine from reaching its optimum running temperature.
Consequently, both consumption (from +15 to +30% on
the urban cycle) and emissions will increase.
Traffic and road conditions
Heavy traffic, for instance when travelling in a queue with
frequent use of low gears or in cities with lots of traffic
lights, causes fairly high fuel consumption. Mountain roads
and uneven surfaces also have a negative effect on con-
sumption.
Traffic hold-ups
During prolonged hold-ups (e.g. at level crossings) the
engine should be switched off.

Under these conditions, the vehicle can continue trav-
elling at moderate speed without demanding exces-
sive effort from the engine. Prolonged use of the ve-
hicle with the warning light on may cause damage. Go
to a Fiat Dealership as soon as possible.
The warning light goes out after the fault disappears,
but the notification is stored in the system.
❒flashing: this indicates possible damage to the catalytic
converter (see “EOBD system” in the “Dashboard and
controls” section).
If the light flashes, come off the accelerator pedal to
reduce engine revs until the warning light stops flash-
ing; continue the journey at moderate speed, trying
to avoid driving conditions that may cause further flash-
ing, and get to a Fiat Dealership as soon as possible. INJECTION SYSTEM FAILURE

Injection system failure
Under normal conditions, turning the ignition key to MAR,
the warning light turns on but it should go off after the
engine starts. If the warning light stays on or comes on
when travelling, it means there is a fault in the injection
system which could cause loss of performance, poor han-
dling and high fuel consumption levels.
A specific message is displayed on certain versions.
Under these conditions, the vehicle can continue travel-
ling at moderate speed without demanding excessive ef-
fort from the engine. In any case, you should go to a Fiat
Dealership as soon as possible.
EOBD engine management system failure
Under normal conditions, turning the ignition key to MAR,
the warning light turns on but it should go off after the
engine starts.
This indicates that the warning light is working correctly.
If the warning light either stays on or comes on during
your journey:
❒on permanently: this means there is a fault in the sup-
ply/ignition system which could cause high exhaust
emissions, loss of performance, poor handling and high
fuel consumption levels.

FUEL RESERVE
(amber)
When the ignition key is turned to MAR, the
warning light turns on but should go off after a
few seconds.
The warning light turns on when 8-10 litres of fuel are
left in the tank.
IMPORTANT The warning light will blink to indicate a sys-
tem failure. If this happens, go to a Fiat Dealership to have
the system checked. DPF (PARTICULATE FILTER)
CLEANING IN PROGRESS
(only Multijet versions with DPF
– amber)
When the ignition key is turned to MAR, the warning light
turns on but should go off after a few seconds. The warn-
ing light stays on constantly to notify the driver that the
DPF system needs to eliminate captured pollutants (par-
ticulate) by the regeneration process.
The warning light does not come on during every DPF
regeneration, but only when driving conditions require
notification to the driver.
The warning light will go off if the vehicle stays in motion
until regeneration has been completed. The process nor-
mally takes about 15 minutes. Optimum conditions for
completing the process are achieved by travelling at
60 km/h with engine revs above 2000 rpm.
If this warning light comes on, it does not mean the vehi-
cle is defective, so there is no need to take it to a garage.
A specific message will appear on the display when the
warning light comes on (for versions/markets where pro-
vided).
h
ç
Always drive at a speed appropriate to the
traffic conditions, the weather and speed
limits. The engine may be turned off while the DPF
light is on; however, repeated interruption of the
regeneration process may result in premature degra-
dation of the engine oil. For this reason, it is always
advisable to wait for the light to go off before turn-
ing off the engine, following the instructions ap-
pearing above. It is recommended to complete DPF
regeneration with the vehicle stationary.

tion. If warning light
ccomes on (with a message
on the display on some versions), go to a Fiat Deal-
ership as soon as possible to have the system bled.
Water may have entered the tank if this appears
immediately after refuelling: if this happens, switch
the engine off immediately and contact a Fiat Deal-
ership.
