IMPORTANT
22) For diesel engines, use only
diesel fuel for motor vehicles
in accordance with EN590
European specifications. The use
of other products or mixtures
may damage the engine beyond
repair and consequently invalidate
the warranty, due to the damage
caused. If you accidentally refuel
with another type of fuel, do not
start the engine, and drain the
tank. If the engine has run, even
for a very short time, you will need
to have the entire fuel supply
system emptied in addition to the
tank.
23) Do not bring naked flames or lit
cigarettes near the fuel tank filler:
fire risk. Keep your face away
from the fuel filler to prevent
breathing in harmful vapours.
SAVING FUEL
Some useful tips are given below for
fuel saving and reducing harmful
emissions of CO2 and other
pollutants (nitrogen oxides, unburnt
hydrocarbons, Particulate Matter
(PM), etc.).
PRACTICAL ADVICE
FOR REDUCING FUEL
CONSUMPTION AND
HARMFUL EMISSIONS
Vehicle conditions
❒Have checks and adjustments for
vehicle maintenancecarried out
in accordance with the “Scheduled
servicing plan”.
❒Checktyrepressure regularly, at
least once every four weeks.
Excessively low pressures will
increase consumption because
rolling resistance will be higher. In
addition, this wears the tyre more
quickly and impairs performance.
❒Only usesnow tyreswhen
the weather conditions make them
absolutely necessary. They increase
consumption and noise.❒Do not travel witha heavy load: the
weight of the vehicle (especially when
driving in town) and its geometry
greatly affect fuel consumption and
stability.
❒Removeroof racks or ski racks
after use. These accessories reduce
the vehicle's aerodynamic
penetration and have a negative
effect on fuel consumption.
❒When transporting particularly large
objects, use atrailerif possible.
❒Use the vehicle's air vents if possible:
travelling with the windows open
impairs aerodynamics.
❒Use electrical devices only for the
amount of time needed. The vehicle’s
heated rear window, additional
headlights, screen wipers and heater
fan require a considerable amount
of energy; this increases fuel
consumption (by up to +25% in an
urban cycle).
❒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.
154
STARTING AND DRIVING

FUEL CUT-OFF
SYSTEM
This intervenes in the case of an
impact causing:
❒the fuel supply cut-off with the engine
consequently switching off;
❒the automatic unlocking of the doors;
❒the switching on of the interior lights;
❒switching on of the hazard warning
lights (to deactivate the lights press
the dedicated button on the
dashboard).
122)
When the system has been
triggered, the message “Fuel cut off,
see handbook” is displayed on
some versions.
Check carefully for fuel leaks, for
instance in the engine compartment,
under the vehicle or near the tank
area.
After a collision, turn the ignition key
to STOP to prevent the battery
from running down.
The following procedure should be
carried out to restore the correct
operation of the vehicle:
❒turn the ignition key to the MAR
position;❒activate the right direction indicator;
❒deactivate the right direction
indicator;
❒activate the left direction indicator;
❒deactivate the left direction indicator;
❒activate the right direction indicator;
❒deactivate the right direction
indicator;
❒activate the left direction indicator;
❒deactivate the left direction indicator;
❒turn the ignition key to the OFF
position.
WARNING
122) If, after an impact, you smell
fuel or notice leaks from the fuel
supply system, do not reactivate
the system to avoid the risk of fire.
LIFTING THE
VEHICLE
If the vehicle needs to be lifted, go
to a Fiat Dealership which is
equipped with the arm hoist or
workshop lift.

Have the air cleaner or the pollen
filter replaced by a Fiat Dealership.

IMPORTANT
36) The presence of water in the
supply circuit may cause severe
damage to the injection system
and irregular engine operation. If
the
warning light comes on,
go to a Fiat Dealership as soon as
possible to have the system bled.
If this problem is indicated
immediately after refuelling, water
may have entered the fuel tank.
In this case, immediately turn off
the engine and contact a Fiat
Dealership.
BATTERY
The battery is of the “limited
maintenance” type: under normal
conditions of use, the electrolyte
does not need topping up with
distilled water.
It does, however, need to be
checked periodically at a Fiat
Dealership or by specialist personnel
to make sure it is working correctly.
133) 134)
REPLACING THE
BATTERY
If required, replace the battery with
an original spare part with the same
specifications.
If a battery with different
specifications is fitted, the service
intervals given in the “Scheduled
Servicing Plan” will no longer be
valid.
Follow the battery manufacturer's
instructions for maintenance.

USEFUL TIPS FOR
EXTENDING BATTERY
LIFE
To avoid draining your battery and
make it last longer, observe the
following instructions:
❒when you park the vehicle, ensure
that the doors, tailgate and bonnet
are closed properly, to prevent any
roof lights from remaining on inside
the passenger's compartment;
❒switch off all roof lights inside the
vehicle: the vehicle is however
equipped with a system which
switches all internal lights off
automatically;
❒do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched
on for a long time when the engine
is not running;
❒before performing any operation on
the electrical system, disconnect
the negative battery pole;
❒completely tighten the battery
terminals.
IMPORTANT If the charge level
remains under 50% for a long time,
the battery is damaged by
sulphation, reducing its capacity and
efficiency at starting.The battery is also more prone to
the risk of freezing (already at
temperatures of -10°C). Refer to the
paragraph "Vehicle inactivity" in
"Starting and driving" if the vehicle is
left parked for a long time.
If, after buying the vehicle, you want
to install electric accessories which
require permanent electric supply
(alarm, etc.) contact a Fiat
Dealership whose qualified
personnel, in addition to suggesting
the most suitable devices from the
Lineaccessori Fiat, will evaluate
the overall electric absorption,
checking whether the vehicle's
electrical system is capable of
withstanding the load required, or
whether it should be integrated with
a more powerful battery.
Since some of these devices
continue to consume electricity even
when the engine is off, they
gradually run down the battery.
WARNING
133) Battery fluid is poisonous and
corrosive. Avoid contact with
skin and eyes. Keep naked flames
or possible sources of sparks
away from the battery: risk
of explosion or fire.
134) Using the battery when the fluid
is too low can damage it
irreparably and generate a risk of
explosion.
135) When performing any operation
on the battery or near it, always
protect your eyes with special
goggles.
209

RUBBER HOSES
As far as the maintenance of the
brake system and fuel supply
system rubber hoses is concerned,
follow the "Scheduled Servicing
Plan" in this chapter carefully.
Ozone, high temperatures and
prolonged lack of fluid in the system
may cause hardening and cracking
of the hoses, with possible leaks.
Careful checking is therefore
necessary.
PROLONGED
VEHICLE INACTIVITY
If the vehicle needs to be off the
road for longer than one month, the
following precautions must be
taken:
❒park the vehicle indoors in a dry and,
if possible, well-ventilated place;
❒engage a gear and check that the
handbrake is not engaged;
❒disconnect the negative terminal from
the battery pole (see paragraph
“Vehicle inactivity” in the "Dashboard
and controls" chapter) and check
the charge conditions (see paragraph
“Battery” in the “Care and
maintenance” chapter);
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds
available commercially;
❒sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glass;
❒slightly open the windows;❒cover the vehicle with a piece of
fabric or perforated plastic sheet. Do
not use compact plastic tarpaulins,
which prevent humidity from
evaporating from the surface of the
vehicle;
❒inflate tyres to +0.5 bar above the
standard specified pressure and
check it at intervals;
❒do not drain the engine cooling
system.
