LPG TANK
28)
The car has a (pressurised) tank A fig.
43 for accumulating LPG in a liquid
state. It is ring-shaped and located in
the spare wheel compartment with
suitable protection.
The LPG in the tank is always in both a
liquid and gaseous state, in physical
balance between the two stages.The liquid, which cannot be
compressed, dilates by around 0.25%
for each increase in temperature of
one degree. For this reason a suitable
free gap allowing the increase in volume
of the liquid for all expected
temperature increases is guaranteed
(e.g. car parked in the sunshine in
summer), without compromising tank
integrity.
A safety valve has been fitted to this
end, to automatically limit the refilling of
the tank (during refuelling) to a
maximum level of 80% (liquid) of its
total capacity.
LPG tank certification
The LPG tank is certified in accordance
with the regulations in force.
In Italy, the tank has a life of 10 years
starting from the car registration date. If
the vehicle has been registered in a
country other than Italy, the duration
and the testing/inspection procedures
of the LPG tank can vary depending on
the national laws of that country. In all
case, when the time limit for your
country has expired, go to a Fiat Dealer
to have the tank replaced.
The tank identification data are printed
on the tank, under the multivalve unit:
type-approval country identification
and type-approval number;
type of gas for which it is designed
(LPG);
name of tank manufacturer;
tank commissioning pressure (30
bar);
maximum refilling percentage (80%);
tank dimensions;
rated tank capacity in litres;
tank manufacture date (month/year);
tank serial number.
LPG/PETROL SWITCH
37)
29)
It is located in the centre tunnel fig. 44
and includes:
Apetrol/LPG switch.
BLPG quantity indicator; 5 LEDs,
four green and one orange to indicate
reserve. The orange LED turns on when
only one green LED is on.
Cpetrol operating mode indicator:
orange LED next to the switchA.
This function is controlled directly by
the LPG control unit.
DLPG operating mode indicator:
green LED next to the switchA. This
function is controlled directly by the
LPG control unit.

KNOWING YOUR CAR

WARNING
25)The system operates at temperatures
ranging between −20°C and 100°C.
26)The car is equipped with a gaseous
LPG injection system designed specifically
for it: it is therefore absolutely forbidden
to alter the configuration of the system or
its components. The use of other
components or materials could cause
malfunctions and lead to a reduction in
safety; therefore, in the case of problems,
contact a Fiat Dealership. To prevent
damage to the gas system parts when
towing or raising the vehicle, follow the
instructions in the "Towing the vehicle"
paragraph of the Owner Handbook.
27)When painting in an oven, the LPG
tank must be removed from the car and
later refitted by a Fiat Dealership. Although
the LPG system has numerous safety
features, it is advisable to proceed
as follows every time the vehicle is not in
use for a long period or moved in an
emergency as a result of a breakdown or
accident: unscrew the fastening devices A
fig. 41, then remove the cover B. Close
the LPG cock rotating the ring nut C
clockwise fig. 42; refit the cover and tighten
the fixing devices.28)Periodically (at least once every six
months), it is advisable to let the LPG in the
tank run out and, at the next refuelling,
check that it does not exceed the
maximum capacity of 30.5 litres (reserve
included) (with a tolerance of 2 litres
excess) (see instructions in the "Capacities"
paragraph). If the level is above 30.5 litres
(reserve included) contact a Fiat Dealership
immediately.
29)In particular usage conditions, such as
starting and operation at low ambient
temperature or LPG supply with low
propane content, the system may switch
temporarily to petrol operation, without
a visual indication of switching on the
selector. If the level of LPG in the tank is
low or there is a request for high
performance (e.g. overtaking, car fully
laden, steep hills): the system can
automatically switch to petrol operation to
guarantee the required engine
performance; in this event, the performed
switching is shown by the orange (petrol)
LED lit and the green (LPG) LED off on the
switch. When the above conditions stop,
the system automatically restores the LPG
operation; the orange (petrol) LED turns
off and the green (LPG) LED is lit on the
switch. To achieve the automatic switching
described above, make sure that there is
always enough fuel in the petrol tank.
30)It is strictly forbidden to use any
additive in the LPG.

KNOWING YOUR CAR

WARNING
45)If the system signals a pressure decrease on a specific tyre, it is recommended to check the pressure on all four tyres. The iTPMS does
not relieve the driver from the obligation to check the tyre pressure every month; it is not to be considered a system to replace servicing or
a safety system. Tyre pressure must be checked with tyres cold. Should it become necessary for whatever reason to check pressure with
warm tyres, do not reduce pressure even though it is higher than the prescribed value, but repeat the check when tyres are cold.
46)The iTPMS cannot indicate sudden tyre pressure drops (for example when a tyre bursts). In this case, stop the vehicle, braking with
caution and avoiding abrupt steering. The system only warns that the tyre pressure is low: it is not able to inflate them. Insufficient tyre
inflation increases fuel consumption, reduces the tread duration and may affect the capacity to drive safely.
Green warning lights

The warning light switches on when the side lights or dipped headlights are turned on.
Follow Me Home
The warning light comes on, on some versions along with a dedicated message on the display, when the
"Follow me home" device is used.
greenFOG LIGHTS
The warning light comes on when the front fog lights are turned on.
greenLEFT DIRECTION INDICATOR
The warning light turns on when the direction indicator control lever is moved downwards or, together with
the right indicator, when the hazard warning light button is pressed.

Under special conditions (e.g. car
loaded asymmetrically on one side,
damaged or worn tyre, fitting the
space-saver spare wheel, fitting snow
chains, fitting different tyres on the
axles) the system may give false
warnings or be temporarily deactivated.
If the system is temporarily deactivated
the
warning light flashes for about
75 seconds and then is continuously
on; at the same time, the display shows
a warning message.
This warning is displayed also after the
engine has been switched off and
then on again if the correct operating
conditions are not restored.
WARNING
77)If the system signals a pressure
decrease on one or more tyres, it
is recommended to always check the
pressure on all four tyres.
78)The iTPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not to
be considered a system to replace
maintenance or a safety system.
79)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.80)The iTPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.
81)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
82)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.

PROTECTION
SYSTEMS
some of the most important safety
equipment of the vehicle comprise the
following protection systems:
seat belts;
SBR (Seat Belt Reminder) system;
head restraints;
child restraint systems;
Front airbags and side bags.
Read the information given the
following pages with the utmost care. It
is of fundamental importance that the
protection systems are used in the
correct way to guarantee the maximum
possible safety level for the driver and
the passengers.
For the description of the head restraint
adjustment see the "Head restraints"
paragraph in the "Knowing your
vehicle" chapter.

Top speed
Fuel consumption considerably
increases as speed increases. Maintain
a constant speed, avoiding
unnecessary braking and acceleration,
which cost in terms of both fuel
consumption and emissions.
Acceleration
Accelerating violently severely affects
consumption and emissions:
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.
Consequently, both consumption (from
+15 to +30% on the urban cycle) and
emissions will increase.
Traffic and road conditions
High fuel consumption is caused by
heavy traffic, for instance when
travelling in a queue with frequent use
of low gears or in cities with many traffic
lights. Winding mountain roads and
rough road surfaces also adversely
affect consumption.Stops in traffic
During prolonged hold-ups (e.g. level
crossings) switch off the engine.REFUELLING THE
VEHICLE
138) 139) 140)
Before refuelling, make sure that the
fuel type is correct. Also stop the
engine before refuelling.
PETROL VERSIONS
Only use unleaded petrol with a number
of octanes (R.O.N.) not lower than 95
(EN228 specification).
IMPORTANT An inefficient catalytic
converter leads to harmful exhaust
emissions, thus contributing to air
pollution.
IMPORTANT Never introduce leaded
petrol to the tank, even in small
amounts in an emergency, as this
would damage the catalytic converter
beyond repair.
REFUELLING CAPACITY
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Further
top-ups could cause faults in the fuel
feeding system.

JUMP STARTING
If the battery is flat, a jump starting can
be performed using the battery and
the cables of another car, or using an
auxiliary battery. In all cases, the battery
used must have a capacity equal to or
a little higher than the flat one.
Jump starting may be dangerous if
carried out incorrectly: carefully follow
the procedures described below.
IMPORTANT NOTES
After turning the ignition key to STOP
and having closed the driver's side
door, wait at least one minute before
disconnecting the battery and then
reconnecting the electrical supply to the
battery.
Do not use an auxiliary battery or any
other source of external supply with
a voltage above 12 V: the battery, the
starter, the alternator and the electrical
system of the car could be damaged.
Do not attempt jump starting if the
battery is frozen. The battery could
break and explode!JUMP STARTING166) 167) 168)
56) 57) 58)
If the battery is flat, the engine may be
started using an auxiliary battery fig.
127, with the same capacity or a little
higher than the flat one.
Proceed as follows to start the car:
connect the positive terminals (+
mark near the terminal) of the two
batteries using a suitable lead;
with a second lead, connect the
negative terminal – of the auxiliary
battery to an earth point
on
the engine or the gearbox of the car to
be started;
start the engine;
when the engine has been started,
remove the leads reversing the order
above.For versions with Start&Stop
In the case of emergency starting,
NEVER connect the negative lead (–) of
the auxiliary battery to negative pole
(–) of the battery, but only to an earth
point on the engine/gearbox assembly.
If after a few attempts the engine does
not start, do not persist but contact
a Fiat Dealership.
IMPORTANT Do not directly connect
the negative terminals of the two
batteries: sparks could ignite explosive
gas released from the battery. If the
auxiliary battery is installed on another
car, prevent accidental contact
between metallic parts of the two cars.
BUMP STARTING
Never bump start the engine by
pushing, towing or driving downhill.
This could cause fuel to flow into the
catalytic converter and damage it
beyond repair.
IMPORTANT Remember that the brake
servo and electrical power steering
system (for versions/markets, where
provided) are not active until the engine
is started. A much greater effort will
therefore be required to use the brake
pedal or turn the steering wheel.
