❒downhill: vehicle stationary on a road with a gradient
higher than 5%, engine running, clutch and brake
pedal pressed and reverse gear engaged.
At pickup the
ESPsystem control unit will maintain the
braking pressure at the wheels until the necessary torque
for starting is reached or, in any case, for a maximum of
2 seconds in order to move easily from the brake pedal
to the accelerator pedal. 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 warning
The
áwarning light in the instrument panel will come
on in the event of a failure (see “Warning lights and
messages” section).
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 first gear. FAILURE WARNING
In the event of a failure, the ESP will be automatically
switched off and the áwarning light will come on
constantly in the instrument panel along with a message
in the multifunction display (for versions/markets where
provided) (see “Warning lights and messages” section).
The LED in the ASR OFF button will light up. Contact
a Fiat Dealership as soon as possible if this happens.
Do not take unnecessary risks, even if
your vehicle is fitted with an ESP system.
Your driving style must always be suited to the
road conditions, visibility and traffic. The driver
is ultimately responsible for road safety.
WARNING
HILL HOLDER SYSTEM
This system is an integral part of the
ESPsystem and it is
provided to facilitate starting on hills.
It is automatically activated in the following conditions:
❒uphill: vehicle stationary on a road with a gradient
higher than 5%, engine running, clutch and brake
pedal pressed, gearbox in neutral or gear other than
reverse engaged;
For the correct operation of the ESP and
ASR systems, the tyres must absolutely be
the same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size specified.

MSR system
(engine braking torque control)
This is an integral part of the ASR system that, in the
event of a sudden gear down shift, cuts in and provides
torque to the engine thus preventing excessive drive
wheel drive which, especially in poor grip conditions,
can lead to a loss of stability. ASR SYSTEM (Antislip Regulator)
This is a traction control system that cuts in
automatically every time one or both drive wheels slip.
Depending on the slipping conditions, two different
control systems are activated:
❒if the slipping involves both drive wheels, the ASR
function intervenes by reducing the power
transmitted by the engine;
❒if the slipping only involves only one driving wheel,
the ASR system cuts in by automatically braking the
wheel that is slipping.
The action of the
ASRis particularly helpful in the
following circumstances:
❒slipping of the inner wheel when cornering due to
the effect of dynamic load changes or excessive
acceleration;
❒too much power transmitted to the wheels also in
relation to the conditions of the road surface;
❒acceleration on slippery, snowy or icy surfaces;
❒loss of grip on a wet surface (aquaplaning).
For the correct operation of the ESP and
ASR systems, the tyres must absolutely be
the same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size specified.

TRACTION PLUS SYSTEM
(for versions/markets, where provided)
Traction Plus is a help with driving and setting off in
poor grip conditions (snow, ice, mud, etc.) which allows
the drive force to be evenly distributed over the same
axle when both wheels are 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 turned on manually by pressing the
T+ button fig. 130 on the dashboard and works below a
level of 30 km/h. Over this speed, it is automatically
deactivated (the LED on the button is still on) and it is
reactivated again when the speed is below 30 km/h.Traction Plus operation
The system is deactivated when starting up. To activate
the “Traction Plus” system, press the button
(T+ fig. 130): 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 ácomes on
steady.
