HILL HOLDER SYSTEM
This system is an integral part of the ESP system and it is
provided to facilitate 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
depressed 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 ESP system control unit maintains
the braking pressure at the wheels until the engine
torque required for departure is reached, or for a
maximum of 1 second, allowing your right foot to be
moved easily from the brake pedal to the accelerator.
If the vehicle has not departed after this time, the
system will deactivate automatically, gradually releasing
the brake force.
At release, the typical brake disengagement noise
indicating that the car is going to move will be heard.Failure indications
A system fault is indicated by the switching on of the
warning light áand by the dedicated message on the
reconfigurable multifunction display (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 handbrake, turned the engine off and
engaged first gear.
For the correct operation of the ESP and
ASR systems, the tyres must be the same
make and type on all wheels, in perfect
condition and, above all, of the type, make and
size specified.

For the correct operation of the ESP and
ASR systems, the tyres must be the same
make and type on all wheels, in perfect
condition and, above all, of the type, make and
size specified.
WARNINGASR SYSTEM (Antislip Regulator)
This function controls car drive and intervenes
automatically every time one or both driving wheels slip.
Depending on the slipping conditions, two different
control systems are activated:
❒if both drive wheels are slipping, the ASR function
intervenes by reducing the power transmitted by the
engine;
❒if the slipping only involves only one drive wheel, the
ASR system intervenes automatically braking the
wheel that is slipping.
The action of the ASR system is 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 in
relation to the conditions of the road surface;
❒acceleration on slippery, snowy or icy surfaces;
❒loss of grip on a wet surface (aquaplaning).Failure indications
In the event of a failure, the ASR will be automatically
switched off and the warning light áwill appear on the
instrument panel along with a message on the
reconfigurable multifunction display (see “Warning lights
and messages”). In this case, contact an Abarth
Dealership as soon as possible.

SNOW TYRES
Use snow tyres of the same size as the normal tyres
provided with the car.
Winter tyres 205/45 R17”- 88Q (M+S) are available at
Abarth Dealerships to be used if the car is mainly driven
on snow-covered roads.
For the type of tyre to be used, inflation pressures and
the specifications of snow tyres, follow the instructions
given in paragraph “Wheels” in section “Technical
specifications”.
The performance of these tyres is considerably reduced
when the tread depth is less than 4 mm. Replace them
in this case.
Due to snow tyre features, under normal conditions of
use or on long motorway journeys, the performance of
these tyres is much lower than that of standard tyres.
Limit performance according to the use for which they
were certified.
The max. speed of snow tyres with “Q”
marking is 160 km/h. The Highway Code
speed limits must however always be complied
with.
WARNING
IMPORTANT When snow tyres are used with a
maximum speed index below the one that can be
reached by the car (increased by 5%), place a notice in
the passenger compartment, plainly in view, which states
the maximum permissible speed of the snow tyres (as
per an EC Directive).
All four tyres should be the same (brand and track) to
ensure greater safety when driving and braking and
better driveability.
Remember that it is inadvisable to change the rotation
direction of tyres.
