Values displayed
Range
Shows the approximate distance the vehicle can travel with
the amount of fuel left in the tank. The display will show
the reading “----” when the following events take place:
– range is lower than 50 km (or 30 mi)
– vehicle is left parked with the engine running for a long
time.
WARNING The range can be affected by several factors:
driving style (see “Driving style” in the “Starting and dri-
ving” section), type of route (motorway, towns and cities,
mountain roads, etc.), conditions of use (load, tyre pres-
sures, etc.). Trip planning must therefore take the above
into account.
Distance travelled
Shows the distance covered since the start of the new jour-
ney.
Average consumption
Shows the approximate average fuel consumption since
the start of the new journey.
Current consumption
Shows the constantly updated fuel consumption. The read-
ing “----” appears on the display if the vehicle is parked with
the engine running.
Average speed
Shows the average speed of the vehicle by using the over-
all time elapsed since the start of a new journey.TRIP COMPUTER
General information
The Trip computer is used to display information on ve-
hicle operation when the ignition key is turned to MAR.
This function allows you to define two separate trips, called
“Trip A” and “Trip B”, for monitoring the vehicle’s „com-
plete mission” (journey) in a reciprocally independent man-
ner. Both functions can be reset (reset – start of a new
journey).
“Trip A” is used to display the figures relating to:
– Range
– Distance travelled
– Average consumption
– Instant consumption
– Average speed
– Travel time (driving time).
“Trip B”, available on multifunction display only, is used to
display the figures relating to:
– Distance travelled B
– Average consumption B
– Average speed B
– Travel time B (driving time).
N.B. “Trip B” may be disabled (see “Activating Trip B”).
“Range” and “Instant consumption” parameters cannot be
reset.

ENERGY SAVING FUNCTION
(for versions/markets where provided)
If, after the engine has been automatically restarted, the
driver does not take any action for a period of about 3 min-
utes, the Start&Stop system will definitively stop the en-
gine to avoid fuel consumption. The engine can only be
started using the key in such cases.
N.B.: In any case, it is possible to keep the engine running
by deactivating the Start&Stop system.
OPERATING IRREGULARITIES
In the case of malfunctions the Start&Stop system is dis-
abled. The driver is informed of the problem by the gen-
eral failure warning light A-fig. 105, where provided, com-
ing on with an information message and the system fail-
ure symbol B-fig. 105 in the control panel.
In this case, contact the Fiat Service Network.VEHICLE INACTIVITY
Versioni con falso polo fig. 106
If the vehicle is inactive, special care must be taken to dis-
connect the battery electrical power supply. This proce-
dure is carried out by disconnecting the rapid release neg-
ative terminal A from the negative false pole B because
there is a battery status monitoring sensor D at the neg-
ative battery pole C which should never be disconnected
except if the actual battery is replaced.

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.

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
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.

TOWING 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 en-
gine should be switched off.

A specific message is displayed on certain versions.
Under these conditions, the vehicle can continue trav-
elling at moderate speed without demanding excessive
effort from the engine. Prolonged use of the vehicle
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 re-
duce engine revs until the warning light stops flashing;
continue the journey at moderate speed, trying to avoid
driving conditions that may cause further flashing, 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 en-
gine 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 handling and
high fuel consumption levels.
A specific message is displayed on certain versions.
Under these conditions, the vehicle can continue travel-

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 en-
gine 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.

travelling, the warning light comes on either per-
manently or flashing (along with a message on the
display on certain versions). The operation of the
Uwarning light may be checked by traffic police
using appropriate equipment. Respect the regula-
tions in force in the country where you are driving.

FUEL CONSUMPTION
The fuel consumption figures, in the tables below, have
been determined according to the homologation tests laid
down by specific European Directives.
The procedures below are followed for measuring con-
sumption and emissions:
❒urban cycle: cold start and driving style that replicates
the speed and gear changes as per the European di-
rective. There are a series of accelerations, decelera-
tions, constant speeds and stops with engine idling. The
top speed reached during the cycle is 50 km/h and the
average speed is 19 km/h.
❒extra-urban cycle: done after the urban cycle as per
the European directive. The top speed reached dur-
ing the cycle is 120 km/h and the average speed is
63 km/h.
❒combined cycle: determined by an average of the ur-
ban cycle (37 per cent weighting) and extra-urban cy-
cle (63 per cent weighting) consumptions.IMPORTANT
In practice, fuel consumption may be higher than the val-
ues obtained during the approved tests. Here are some of
the major factors that can lead to a difference between
test and real consumption.
1) Vehicle condition: inadequate servicing, use of roof
racks, trailers, heavy loading, high usage of electrical de-
vices and the air conditioning.
2) Driving style: frequent cold starts for short journeys,
poor engine warming technique, gear selection, high
speeds, sudden acceleration and braking.
3) Traffic and road conditions: driving in traffic, steep hills
or winding roads, road surface conditions.
4) Atmospheric conditions: intemperate weather, wind,
rain, snow, high altitude.
5) Proportion of use in towns and cities, in the country
and on motorways.
