The symbol switches on in the event of fuel level sensor failure. Contact a Fiat Dealership.
yellowENGINE OIL DETERIORATED
(where provided)
Diesel versions: the symbol turns on and is displayed for 3 minute cycles and intervals of 5 seconds until
the oil is changed.
The symbol is displayed until the problem is solved.
Petrol versions: the symbol switches on and then is not displayed when the display cycle is completed.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on
as described above until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is
now necessary to change the oil as a result of regular use of the vehicle.
The deterioration of engine oil is accelerated by using the vehicle for short drives, preventing the engine
from reaching operating temperature.

ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
DTC (Drag Torque Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
DST (Dynamic Steering Torque);
ERM (Electronic Rollover Mitigation);
TSC (Trailer Sway Control).
For the operation of the systems, see
the following description.
ABS (Anti-lock Braking
System)
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the vehicle
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.The system also improves control and
stability of the vehicle when braking on
a surface where the grip of the left and
right wheels varies, or on corners.
The Electronic Braking Force
Distribution (EBD) system completes
the system allowing the brake force to
be distributed between the front and
rear wheels.
System intervention
The driver can feel that the ABS system
has come into action because the
brake pedal pulsates slightly and the
system gets noisier: this is entirely
normal with the system operating.
31) 32) 33) 34) 35) 36) 37)
DTC (Drag Torque
Control) SYSTEM
The DTC (Drag Torque Control) system
prevents the drive wheels from possibly
locking, which could happen, for
example, if the accelerator pedal is
released suddenly or in the case of a
sudden downshifting in conditions of
poor grip. In this conditions, the engine
braking effect could cause the drive
wheels to slip, resulting in a loss of car
stability. In these situations, the DTC
system intervenes, restoring torque to
the engine in order to conserve car
stability and increase car safety.
ESC (Electronic Stability
Control) SYSTEM
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the vehicle’s
understeer and oversteer, distributing
the brake force on the wheels
appropriately. The torque supplied by
the engine can also be reduced in order
to maintain control of the vehicle.
The ESC system uses sensors installed
on the vehicle to determine the
trajectory that the driver intends to
follow and compares it with the
vehicle’s effective trajectory. When the
real trajectory deviates from the desired
trajectory, the ESC system intervenes to
counter the vehicle’s understeer or
oversteer.
Oversteer: occurs when the vehicle is
turning more than it should according
to the angle of the steering wheel.
Understeer: occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
75
38) 39) 40) 41) 42)

In critical situations (braking on surfaces
with different grip conditions), through
the DST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
53)
ERM (Electronic Rollover
Mitigation) SYSTEM
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It is
not possible to avoid tendency to roll
over if the phenomenon is due to
reasons such as driving on high side
gradients, collision with objects or other
vehicles.
54)
TSC (Trailer Sway
Control) SYSTEM
The system employs a series of sensors
located on the vehicle to identify
excessive swerving of the trailer and
take the necessary precautions to
eliminate it.
To counteract the effect of trailer sway,
the system can reduce the engine
power and intervene on the wheels
involved. The TSC system activates
automatically once excessive sway of
the trailer is detected.
System intervention
When the system is active, the
warning light flashes on the
instrument panel, the engine power is
reduced and braking can be felt on the
individual wheels, following the attempt
to eliminate the swerving of the trailer.
55) 56)
WARNING
31)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on
the current road conditions.32)To obtain the maximum efficiency of
the braking system, a bedding-in period of
about 500 km is needed: during this period
it is better to avoid sharp, repeated and
prolonged braking.
33)If the ABS intervenes, this indicates
that the grip of the tyres on the road is
nearing its limit: you must slow down to a
speed compatible with the available grip.
34)The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition of
the road.
35)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
36)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
37)For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
38)The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.
39)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
40)The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the safety
of others.
