If you want to carry reserve
fuel in a can, follow law reg-
ulations, only using a certified can,
suitably fastened to the load securing
eyelets. Even in this way the risk of
fire is increased in the case of an ac-
cident.
WARNING
A heavy load that has not
been secured may cause se-
rious harm.

MULTIJET ENGINES
If the outside temperature is very low, the
diesel thickens due to the formation of
paraffins and could clog the diesel fuel fil-
ter.
In order to avoid these problems, different
types of diesel are distributed according to
the season: summer type, winter type and
arctic type (cold, mountain areas).
If refuelling with diesel fuel not suitable for
the current temperature, mix diesel fuel
with DIESEL MIX additive in the propor-
tions stated on the can, putting first the
antifreeze in the tank and then the diesel
fuel.FUEL FILLER CAP fig. 124
The fuel filler cap lock is automatically con-
trolled by the central door lock.
In an emergency (e.g.: electric system fail-
ure) it is possible to unlock it by pulling
string B. To find the string, remove the
right-hand side cover A.
To carry out fuelling, open flap C-fig. 125
and unscrew cap D; the cap is fitted with
an antiloss device Ewhich fastens it to the
flap so it cannot be mislaid.
The sealing of the tank may cause light
pressurising in the tank. A little breathing
off, while slackening the cap, is absolutely
normal. The car must only be filled
with diesel fuel for motor ve-
hicles, in compliance with Eu-
ropean Standard EN590. The
use of other products or mixtures may
irreparably damage the engine with in-
validation of the warranty due to the
damage caused. In the event of acci-
dentally filling with another type of fu-
el, do not start the engine and empty
the tank. If the engine has been run
even for only a very short time, in ad-
dition to the tank, it is also necessary
to drain out the whole fuel circuit.
fig. 124F0L0137m
REFUELLING
To guarantee full tank filling, carry out two
refuelling operations after the first click of
the fuel delivery gun. Avoid further top-
ping up operations that could cause dam-
ages to the fuel system.

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.);
❒diesel particulate filter (DPF). When refuelling, position the cap on the
device inside the flap as shown in the fig-
ure.
If the doors are locked, press the door un-
lock button
´on central panel to refuel.
The fuel filler cap is re-locked when the
doors are locked.
fig. 125F0L0181m
Do not put naked flames or
lighted cigarettes near the
fuel filler hole as there is a danger of
fire. Do not bend too close to the hole
either so as not to breathe in harmful
vapours.
WARNING
During normal service the
diesel particulate filter (DPF)
reaches high temperatures. Do not
therefore park the car over inflam-
mable materials (grass, dry leaves,
pine needles, etc.): fire hazard.

IMPORTANT If it is not possible to turn
the ignition key to ON, remove the emer-
gency key, fit it into slot A-fig. 1to un-
lock the ignition switch; then, turn the key
to ONand follow the starting procedure.
Contact Fiat Dealership.
IMPORTANT Never leave the ignition key
into the ignition switch when the engine
is off. In this event, when opening the dri-
ver’s door, a buzzer will sound for about
1 second.
HOW TO WARM UP THE
ENGINE AFTER IT HAS JUST
STARTED (petrol and diesel
engines)
Proceed as follows:
❒Drive off slowly, letting the engine turn
at medium revs. Do not accelerate
abruptly;
❒Do not drive at full performance for
the initial kilometres. Wait until the
coolant temperature gauge starts
moving.

CORRECT USE
OF THE CAR
Never bump start the engine
by pushing, towing or coasting
downhill as this could cause
fuel to flow into the catalytic
exhaust system and damage it beyond
repair.
A quick burst on the acceler-
ator before turning off the en-
gine serves absolutely no prac-
tical purpose, it wastes fuel
and is damaging especially to tur-
bocharged engines.
Remember that the servo-
brake and power steering
are not operational until the engine
has been started, therefore much ef-
fort than usual is required on the
brake pedal and steering wheel.
WARNING
STOPPING THE ENGINE
Turn the ignition key to OFFwhile the
engine is idling.
IMPORTANT After a taxing drive, you
should allow the engine to “catch its
breath” before turning it off by letting it
idle to allow the temperature in the en-
gine compartment to fall.
IMPORTANT If the engine is turned off
while the car is still moving, for safety rea-
sons it will be impossible to remove the
key from the ignition switch. To remove
the key, turn it to ONand then to OFF
with the car stopped without forcing at re-
moval.

When stopping the car with a gear high-
er than 1st gear, transmission will set au-
tomatically at 1st gear.
When stopping the car under poor grip
conditions (snow, ice), at next starting the
transmission control unit could engage a
gear higher than 1st gear to prevent wheel
slipping. This shall not be considered as a
fault
IMPORTANT: in the event of excessive
oil temperatures (see section “Warning
lights and messages”), the electronic con-
trol intervenes excluding sequential mode
and activating automatic mode in order to
safeguard transmission life. Sequential
mode will be resumed as soon as regular
operating temperatures are restored.AUTOMATIC MODE
D can be selected from sequential mode
under whatever driving condition.
When passing from sequential mode to D,
the gear to engage is selected by trans-
mission control unit according to engine
rpm and speed (accelerator pedal posi-
tion).
Low engine power demand will result in
long gears engagement and reduced fuel
consumption. Increasing speed by press-
ing the accelerator will automatically en-
gage short gears that will result in im-
proved performance as to pickup and ac-
celeration: in this case fuel consumption
will increase.
For speedy pickup:
❒press the accelerator pedal flat-out,
the kick-down device will cut in to ob-
tain max. performance in terms of
pickup and acceleration. In this case fu-
el consumption will obviously increase.
IMPORTANT When driving under poor
grip conditions (snow, ice, etc.) avoid to
engage the kick-down device. SEQUENTIAL MODE
In sequential mode, the electronic auto-
matic transmission works like a fixed gear
sequential gearbox.
From position D move the gear lever left-
wards:
❒move gear lever to +: to upshift;
❒move gear lever to –: to downshift.
Gears are displayed by digits on the in-
strument panel. Non-stop monitoring car-
ried out by transmission control unit ex-
cludes whatever possibility of error.
Downshifting (or upshifting) is only pos-
sible if engine rpm enables it.
In sequential mode, electronic transmis-
sion control can however intervene in self-
adapting mode by shifting gears automat-
ically when engine rpm exceeds or falls be-
low the admitted rpm limit.

CORRECT USE
OF THE CAR

Roof rack/ski rack
Remove the roof rack or the ski rack from
the roof as soon as they are no longer
used. These accessories lower air pene-
tration and adversely affect consumption
levels. When needing to carry particular-
ly voluminous objects, preferably use a
trailer.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window, ad-
ditional headlights, windscreen wipers and
heater fan need a considerable amount of
energy, therefore increasing the require-
ment of current increases fuel consump-
tion (up to +25% in the urban cycle).
Climate control
The air conditioner is an additional load
which greatly affects the engine leading to
higher consumption (on average up to
+20%). When the temperature outside
the car permits it, use the air vents where
possible.
Spoilers
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at
a standstill or at idle or high speed: under
these conditions the engine warms up
much more slowly, increasing electrical
consumption and emissions. It is therefore
advisable to move off immediately, slow-
ly, avoiding high speeds. This way the en-
gine will warm faster.
Unnecessary actions
Avoid accelerating when waiting at traffic
lights or before switching off the engine.
This and also double declutching is ab-
solutely pointless on modern cars and al-
so increase consumption and pollution.
Gear selection
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance in-
creases consumption.
In the same way improper use of a high
gear increases consumption, emissions an
engine wear.CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of your
car down and lower the amount of toxic
emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service schedule”.
Tyres
Check the pressure of the tyres routine-
ly at an interval of no more than 4 weeks:
if the pressure is too low, consumption
levels increase as resistance to rolling is
higher.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the car
(especially when driving in town) and its
trim greatly affects consumption and sta-
bility.

CORRECT USE

Traffic situations and road
conditions
Rather high consumption levels are tied to
situations with heavy traffic, for example
in queues with frequent use of the lower
gears or in cities with many traffic lights.
Also winding mountain roads and rough
road surfaces adversely affect consump-
tion.
Traffic hold-ups
During prolonged hold-ups (e.g.: level
crossings) the engine should be switched
off.TOWING TRAILERS
IMPORTANT NOTES
For towing caravans or trailers the car
must be fitted with a certified tow hook
and an adequate electric system. Installa-
tion should be carried out by specialised
personnel who release a special document
for circulation on the road.
Install any specific and/or additional rear-
view mirrors as specified by law.
Remember that when towing a trailer,
steep hills are harder to climb, the brak-
ing spaces increase and overtaking takes
longer depending on the overall weight.
Engage a low gear when driving downhill,
rather than constantly using the brake.
The weight the trailer exerts on the car
tow hook reduces by the same amount
the actual car loading capacity. To make
sure the maximum towable weight is not
exceeded (given in the log book) account
should be taken of the fully laden trailer,
including accessories and personal be-
longings. Top speed
Fuel consumption considerably increases
with speed. Avoid superfluous braking and
accelerating, which cost in terms of both
fuel and emissions.
Acceleration
Accelerating violently increasing the revs
will greatly affect consumption and emis-
sions: acceleration should be gradual and
should not exceed the maximum torque.
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts do
not allow the engine to reach optimum
operating temperature. This results in a
significant increase in consumption levels
(from +15 to +30% on the urban cycle)
and emission of harmful substances.
