Warning lights on
panelWhat it means What to do
amberGENERAL FAILURE INDICATION
The warning light turns on in the following circumstances:
Engine oil pressure sensor failure
Speed limit (for versions/markets, where provided) a
warning at a fixed speed of 120 km/h is available (cannot
be switched off, cannot be adjusted).
Lights failure (rear fog, direction indicator, reverse,
number plate, side, daytime running)The failure relating to these lights could be: one or
more blown bulbs, a blown protection fuse or a break
in the electrical connection.
Fuel cut-off system failure
Parking sensor failure.
Start&Stop system failureContact a Fiat Dealership as soon as possible to have
the fault fixed.
Airbag failure warning light
The warning light turns on and flashes to indicate a failure
of the
warning light. In this case, thewarning light
may not indicate problems with the airbag restraint
systems.Before continuing, contact a Fiat Dealership to have
the system checked immediately.

IMPORTANT NOTES
The front airbags and/or side bags
(where provided) may be deployed if
the vehicle is subject to heavy knocks
or accidents involving the underbody
area, such as for example violent
shocks against steps, kerbs or low
obstacles, or the vehicle falling into big
potholes or depressions in the road.
A small amount of dust will be released
when the airbags are deployed. The
dust is not harmful and does not
indicate the beginning of a fire.
Furthermore, the surface of the
deployed bag and the interior of the
vehicle may be covered in a dusty
residue: this may irritate your skin and
eyes. Wash with mild soap and water in
the event of exposure.
Should an accident occur in which any
of the safety devices are activated,
take the vehicle to a Fiat Dealership to
have the activated devices replaced
and to have the whole system checked.
Every control, repair and replacement
operation concerning the airbags must
be carried out only at Fiat Dealerships.If you are having the vehicle scrapped,
have the system deactivated at a Fiat
Dealership first. If the vehicle changes
ownership, the new owner must be
informed of how to use the airbags and
the above warnings and also be given
this "Owner Handbook".
Pretensioners, front airbags and front
side bags are deployed differently
according to the type of collision.
Failure to activate one or more of the
devices does not indicate a system
malfunction.

WARNING
83)If thewarning light does not turn on
when the key is turned to MAR, or if it
stays on when travelling (together with the
message on the display on some versions),
there could be a failure in the restraint
systems. If this is the case, the airbags or
pretensioners may not trigger in the event
of an accident or, less likely, they may
trigger accidentally. Contact a Fiat
Dealership immediately to have the system
checked.
84)Do not travel carrying objects in your
lap, in front of your chest or between your
lips (pipe, pencils, etc.): they could cause
severe injury if the airbag is deployed.
85)On cars with side bags, do not cover
the front seat backrests with extra covers.86)If the car has been stolen or in the case
of attempt to steal it, if it has been
subjected to vandalism or floods, have the
airbag system checked by a Fiat
Dealership.
87)If the ignition device is at MAR, even if
the engine is switched off, airbags may
be deployed when the car is stationary and
hit by another car. Therefore, even if the
vehicle is stationary, when an active front
passenger airbag is fitted, DO NOT install
rearward facing child restraint systems
on the front passenger seat. Deployment of
the airbag following an impact could cause
fatal injuries to the child. Therefore, always
deactivate the passenger side airbag
when a rearward facing child restraint
system is installed on the front passenger
seat. The front passenger seat must also
be positioned back as far as possible in
order to prevent the child restraint system
from coming into contact with the
dashboard. Immediately reactivate the
passenger airbag as soon as the child
restraint system has been removed. Also
remember that, if the ignition device is
set to STOP, none of the safety devices
(airbags or pretensioners) will be deployed
in the event of collision. Non-deployment
in such cases does not indicate a system
malfunction.
88)Do not affix rigid objects to the garment
hooks or support handles.
89)Do not rest your head, arms or elbows
on the door, windows or the area in which
the Window bag is located to avoid
possible injury during airbag inflation.
90)Never lean your head, arms or elbows
out of the window.

SAFETY

EMERGENCY START-UP
If the instrument panel warning light
stays on steadily, you can perform
an emergency start by using the code
on the CODE card (see the “In an
emergency” section).
22)
SWITCHING OFF 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 letting
it idle to allow the temperature in the
engine compartment to fall.
WARNING
91)It is dangerous to run the engine in
enclosed areas. The engine consumes
oxygen and engine exhaust contains
carbon dioxide, carbon monoxide and
other toxic gasses.
WARNING
18)It is advisable not to demand maximum
performance from your vehicle (e.g.
excessive accelerations, long distances at
top rpm, excessive intense braking, etc.)
as soon as the engine is started.19)When the engine is switched off never
leave the key turned to MAR-ON to prevent
useless current absorption from draining
the battery.
20)If the warning light
flashes for 60
seconds after starting or during an
extended towing period, this indicates an
anomaly in the glow plug pre­heating
system. Use the vehicle normally if the
engine starts, but contact a Fiat Dealership
as soon as possible.
21)If the engine fails to start with a gear
engaged, the potentially dangerous
situation due to the fact that the gearbox is
automatically placed in neutral will be
signalled by a buzzer.
22)Never bump start the engine by
pushing, towing or coasting downhill. This
could cause fuel to flow into the catalytic
converter and damage it beyond repair.
PARKING THE
VEHICLE
HANDBRAKE
The handbrake lever fig. 122 is located
between the two front seats.
Handbrake engagement:
Pull lever upwards until the vehicle is
secured. The warning light
comes
on with the key at MAR.
Handbrake disengagement:
slightly raise lever A and hold button B
fig. 122 pressed, checking that the
warning light switches off in the
instrument panel

The cold tyre inflation pressure must
not exceed the maximum inflation
pressure value printed on the side of
the tyre.
NOTE
The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
Therefore, the TPMS should not be
used as pressure switch while adjusting
the tyre inflation pressure.
Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency and
tyre tread life and may also affect
handling and braking performance of
the vehicle.
The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with
a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
The TPMS warns the driver of any
condition of insufficient tyre pressure. If
this drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
The seasonal temperature changes
affect tyre pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in all
four tyres are particularly important.
Tyre pressure monitoring system
low pressure warning
IMPORTANT In the case of deflation of
more than one tyre sequentially, without
switching off and on the engine, from
the second tyre involved the acoustic
signal is not activated, only the
dedicated signal is shown on the
display.
To prevent the signal from being stored
in the event of pressure loss of a
subsequent tyre (with deactivation of
the acoustic signal), the ignition key
must be turned to MAR and then to
STOP, each time pressure is restored.
TPMS operation faults
The system fault is indicated by the
warning light
which first flashes for
75 seconds and then stays on steadily.
WARNING
101)The TPMS is optimised for the original
tyres and wheels provided. TPMS
pressures and alerts have been defined
according to the size of the tyres mounted
on the vehicle. Using equipment with
different size, type or kind may cause
irregular system operation or sensor
damage. Non-original spare wheels can
damage the sensor. Do not use tyre
sealant or balancing weights if the vehicle
is equipped with TPMS as these may
damage the sensors.
102)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
103)The TPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not even to be
considered a replacing system for
maintenance or a safety system
104)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.
105)The TPMS 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.

10.0% (V/V) ethanol compliant with
EN228
CNG: Automotive methane and
bio-methane compliant withEN16723
WARNING
28)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
introduce other types of fuel into the tank,
do not start the engine. Empty the tank.
If the engine has been run for even an
extremely limited amount of time, you must
not only drain the fuel tank, but the rest of
the supply circuit as well.
29)Do not approach naked flames or lit
cigarettes to the fuel tank filler: fire risk.
Keep your face away from the fuel filler to
prevent breathing in harmful vapours.
30)Methane refuelling stations are not
authorised to refill the cylinders when the
inspection date has expired. The check
valve prevents the methane from flowing
back to the fuel filler.
TOWING TRAILERS
IMPORTANT
The vehicle must be equipped with a
type-approved tow hook and adequate
electrical system to tow trailers.
Installation should be carried out by
specialised personnel who will issue the
required papers for travelling on roads.
Install any specific and/or additional
door mirrors as specified by the
Highway Code.
Remember that when towing a trailer,
steep hills are harder to climb, braking
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 of the trailer on the vehicle
tow hook will reduce the loading
capacity of the vehicle by the same
amount.
119

FUEL CUT-OFF
SYSTEM
This intervenes in the case of an impact
causing:
the interruption of the fuel supply
with the engine consequently cutting
out;
the automatic unlocking of the
doors;
turning on the lights inside the car;
switching on of the hazard warning
lights (to deactivate the lights press
the dedicated button on the
dashboard).
128)
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 MAR;
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 STOP.
Natural Power versions
In the event of an impact to the car, the
petrol and injection supply is cut off
immediately, causing the engine to cut
out and, as a result, the safety solenoid
valves to close.
WARNING
128)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.
142
IN AN EMERGENCY

TOWING THE
VEHICLE
The tow ring provided with the vehicle
is located in the tool box behind the left
seat backrest (Cargo versions) or in
the boot (Doblò / Doblò Combi
versions).
ATTACHING THE TOW
HOOK
Proceed as follows:
release the cap A fig. 188-fig. 189;
take the tow hook B from the tool
bag;
fully screw the hook onto the
threaded front or rear pin.
129) 130) 131)
39)
Versions with COMFORT-MATIC
transmission or DUALOGIC™
transmission
Make sure that the gearbox is in neutral
(N) (checking that the vehicle moves
when pushed) and proceed in the same
way as for towing a normal vehicle
with a manual transmission.
If the gear lever cannot be put in
neutral, do not tow the vehicle, but
contact a Fiat Dealership.
WARNING
129)Before towing, turn the ignition key to
MAR-ON and then to STOP without
removing it. The steering column
will automatically lock when the key is
removed and the wheels cannot be
steered.130)Before tightening the ring, clean the
threaded housing thoroughly. Make sure
that the ring is fully fastened in the housing
before towing the vehicle. Do not start
the engine whilst the vehicle is being
towed.
131)When towing, remember that greater
effort is required on the brake pedal in
order to brake, since the brake servo is not
providing assistance. Do not use flexible
cables when towing and avoid jerky
movements. During towing operations,
make sure that the fastened joint does not
damage adjoining components. When
towing the vehicle, it is necessary to obey
specific road regulations which relate
both to the towing device as well as to the
behaviour to adopt on the road. Do not
start the engine whilst the vehicle is being
towed.
WARNING
39)The front and rear tow hooks should
be used only for emergencies on the road.
You are allowed to tow the vehicle for
short distances using an appropriate
device in accordance with the highway
code (a rigid bar), to move the vehicle on
the road in readiness for towing or
transport via a breakdown vehicle. Tow
hooks MUST NOT be used to tow vehicles
off the road or where there are obstacles
and/or for towing operations using cables
or other non-rigid devices. In compliance
with the above conditions, towing must
take place with the two vehicles (one
towing, the other towed) aligned as much
as possible along the same centre line.
