Failure indications
A failure of the system is indicated by the
turning on warning light áon the instru-
ment panel together with the dedicated
message on the reconfigurable multifunc-
tional 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 car without having engaged the hand-
brake, turned the engine off and engaged
the first speed.
If the spare wheel is used,
the ESP system keeps oper-
ating. The spare wheel, being smaller
than the original wheel provides less
grip.
For correct operation of the ESP and
ASR systems, the tyres must ab-
solutely be of the same brand and
type on all wheels, in perfect condi-
tions and, above all, of type, brand
and size specified.
WARNING
MSR system
(engine braking torque control)
It is an integral part of the ASR system that
in case of sudden gear downshifting, cuts
in providing torque to the engine thus pre-
venting excessive driving wheel drive that,
specially in poor grip conditions, can lead
to loss of stability.TTC SYSTEM
(Torque Transfer Control)
It is an integral part of the ESP system.
This system improves the transfer of dri-
ve torque to the wheels, guaranteeing
safer and more sporty driving, especially
when cornering, far more able to prevent
understeer.
The system is turned on by pressing the
button in the dashboard C-Fig. 58. The
LED in the TTC button is lit up when it
is on.
It is turned off by pressing the button again
or when the vehicle is switched off (igni-
tion key in STOP position). ASR SYSTEM
(Antislip Regulation)
It’s integral to the ESP system and auto-
matically intervenes in case of slip of one
or both drive wheels, helping the driver
to control the car.
The action of the ASR is particularly help-
ful in the following circumstances:
❒slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒too much power transmitted to the
wheels also in relation to the conditions
of the road surface;
❒acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet sur-
face (acquaplaning).

CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups
will prevent the engine from reaching op-
timal running temperature. Consequently,
both consumption (from +15 to +30% on
urban cycle ) and emissions will increase.
Traffic and road conditions
Rather high 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. Moun-
tain and rough roads also have a negative
effect on consumption.
Traffic hold-ups
During prolonged hold-ups (level crossings)
the engine should be switched off.SNOW TYRES
Use snow tyres of the same size as the
normal tyres provided with the car.
Abarth Dealership will be happy to pro-
vide advice concerning the most suitable
type of tyre for the customer’s require-
ments.
For the type of tyre to be used, inflation
pressures and the specifications of snow
tyres, follow the instructions given in pa-
ragraph “Wheels” in section “Technical
specifications”.
The performance of these tyres is consi-
derably reduced when the tread thickness
is less than 4 mm. Replace them in this ca-
se.
Due to their specific features, the perfor-
mance of snow tyres is much lower than
that of normal types in normal conditions
or long motorway stretches. Limit perfor-
mance according to the use for which they
were approved. Top speed
Fuel consumption considerably increases
as speed increases. Keep your speed as
even as possible, avoiding unnecessary
braking and acceleration which cause ex-
cessive fuel consumption and increase
emissions.
Acceleration
Sudden acceleration has a very negative
effect on consumptions and emissions: ac-
celerate gradually.
