ESC (Electronic Stability Control)
SYSTEM
(for versions/markets, where provided)
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
appropriate wheels. The torque supplied by the
engine can also be reduced in order to maintain
control of the vehicle.
The ESC system uses the sensors in the vehicle to
determine the trajectory required by the driver
through steering and compares it with the real
trajectory of the vehicle. When the real trajectory
deviates from the desired trajectory, the ESC system
intervenes to counter the car’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
The ESC system also includes the following systems:
Hill Holder
ASR
MSR
HBASYSTEM INTERVENTION
It is signalled by the blinking of the instrument panel
warning light
, to inform the driver that the car
is in critical stability and grip conditions.
Switching the system on
The ESC system is automatically activated when the
vehicle is started and cannot be deactivated.
Failure indications
In the event of a failure, the ESC system will be
automatically switched off and warning light
will
switch on constantly on the instrument panel along
with a message on the multifunction display (for
versions/markets where provided) (see chapter
"Warning lights and messages"). Contact a Fiat
Dealership as soon as possible.
WARNING
The ESC system can’t overrule the
natural laws of physics, and can’t
increase the grip available according to the
condition of the road.
WARNING
The ESC system cannot prevent
accidents, including those due to
excessive speed on corners, driving on low-grip
surfaces or aquaplaning.

WARNING
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.
HILL HOLDER SYSTEM
(for versions/markets, where provided)
This system is an integral part of the ESC system and
facilitates starting on slopes.
It is automatically activated in the following
conditions:
uphill: vehicle stationary on a road with a gradient
higher than 5%, engine running, brake pedal
pressed and gearbox in neutral or gear other than
reverse;
downhill: vehicle stationary on a road with a
gradient higher than 5%, engine running, brake
pedal pressed and reverse gear engaged.
When setting off, the ESC system control unit
maintains the braking pressure on the wheels until
the torque necessary for starting is reached, or
in any case for a maximum of 2 seconds, allowing
your right foot to be moved easily from the brake
pedal to the accelerator. When two seconds have
elapsed, without starting, the system is automatically
deactivated, gradually releasing the braking pressure.
During this release stage, the typical brake
disengagement noise indicating that the vehicle is
going to move imminently will be heard.Failure indications
System failure is indicated by instrument panel
warning light
with digital display and warning light
on the instrument panel with multifunction display
(for versions/markets, where provided) (see section
“Warning lights and messages”).
IMPORTANT The Hill Holder system is not a parking
brake; therefore, never leave the vehicle without
having engaged the handbrake, turned the engine off
and engaged the first gear.
WARNING
For the ESC and ASR systems to function
correctly, all four tyres must be the
same brand and type, must be in excellent
condition and, above all, must be of the
prescribed type and size.
ASR SYSTEM (Anti-Slip Regulation)
(for versions/markets, where provided)
This is a traction control system that cuts in
automatically every time one or both drive wheels
slip.
Depending on how slippery the road is, two different
control systems are activated:
if slipping involves both driving wheels, the ASR
function intervenes reducing the power
transmitted by the engine;

INDEX
if the slipping only involves one of the drive
wheels, the ASR intervenes automatically braking
the wheel that is slipping.
The action of the ASR system is especially useful in
the following conditions:
slipping of the inner wheel round bends due to
dynamic variations in the load of excessive
acceleration;
excessive power transmitted to the wheels, also in
relation to road surface conditions;
acceleration on slippery, snowy or icy road
surfaces;
in the case of loss of grip on a wet surface
(aquaplaning).
WARNING
For the ESC and ASR systems to function
correctly, all four tyres must be the
same brand and type, must be in excellent
condition and, above all, must be of the
prescribed type and size.
WARNING
The ASR system cannot overrule the
natural laws of physics, and cannot
increase the grip available according to the
condition of the road.
WARNING
The ASR system cannot prevent
accidents, including those due to
excessive speed on corners, driving on low-grip
surfaces or aquaplaning.
WARNING
The capability of the ASR system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
MSR SYSTEM (engine drive regulation)
This is an integral part of the ESC system that, in the
event of a sudden gear down shift or an ABS braking,
cuts in and provides torque to the engine thus
preventing excessive driving wheel drive which,
especially in poor grip conditions, can lead to a loss
of stability.
Engagement/ disengagement of the ASR
system
The ASR system switches on automatically each time
the engine is started.
When travelling, the ASR system can be switched off
and on again pressing button fig. 101 located among
the controls in the instrument panel.

TRACTION PLUS SYSTEM
(for versions/markets, where provided)
Traction Plus is a driving aid, useful for setting off in
poor grip conditions (snow, ice, mud, etc.) which
allows the drive force to be distributed in the best
way over the front axle when one wheel is slipping.
In effect, Traction Plus acts by braking the wheels
with poor grip (or those slipping more than the
others), thereby transferring the drive force to those
which have more grip on the ground.
This function can be activated manually by pressing
button T+ on the side control panel fig. 102 and
operates under 50 km/h. When this speed is
exceeded, it is automatically deactivated (the LED on
the button is still on) and it is reactivated again
when the speed falls below 50 km/h.Traction Plus operation
The system is deactivated when starting up. To
activate the "Traction Plus" system, press the button
(T+ fig. 102): the LED on the button switches on.
The activation of the Traction Plus system involves
the following functions being switched on:
inhibition of the ASR function, in order to fully
exploit the engine torque;
the differential locking effect on the front axle,
through the braking system, to improve traction
on irregular grounds.
If the "Traction Plus" system is faulty, the "general
failure" instrument panel warning light
comes on
steady.
