MSR system (engine drive regulation)
This is an integral part of the ASR system that, in the
event of sudden gear shifting on hills, cuts in to provide
torque to the engine, thus preventing excessive driving
wheel drag that, especially in poor grip conditions, can
lead to loss of stability.
TTC system (self-locking differential effect)
The TTC system uses the braking system to produce
a behaviour similar to a limited slip differential.
The front braking system, during acceleration while
cornering, acts on the inner wheel, increasing the drive
of the outer wheel (with more load) and distributing the
torque between the front drive wheels dynamically and
continuously according to the driving conditions and the
road surface.
In this way, the system allows particularly effective and
sporty driving to be achieved.
The TTC system intervenes activating the Sport driving
mode of the “Manettino Abarth” system (see the
“Manettino Abarth car dynamic control system (DSS
– Driving Sport Switch)” paragraph in this section).
When the TTC system is active, the ASR system
calibration is changed and made less intrusive.
Do not take unnecessary risks, even if
your vehicle is fitted with this system.
Your driving style must always be suited to the
road conditions, visibility and traffic.
The driver is always responsible for road safety.
WARNING
When travelling on snowy roads with snow chains, it
may be helpful to have the ASR system less intrusive
(activating the Sport driving mode): in these conditions,
the slipping of the drive wheels when setting off makes it
possible to have better traction.

EOBD SYSTEM
The EOBD system (European On Board Diagnosis)
carries out a continuous diagnosis of the components of
the car related to emissions.
It also alerts the driver, by turning on the warning light
Uon the instrument panel (together with relevant
message on the reconfigurable multifunction display)
(see section “Warning lights and messages”), when
these components are no longer in peak conditions.
The goal of the system is to:
❒keep the system efficiency under control;
❒warn when a failure causes emissions levels to
increase;
❒warn of the need to replace deteriorated
components.
The system also has a connector that can be interfaced
with appropriate equipment, which makes it possible to
read the error codes stored in the control unit together
with a series of specific parameters for engine operation
and diagnosis. This check can also be carried out by
traffic control authorities.
Contact an Abarth Dealership as soon as
possible if warning light
Ueither does
not light up when the key is turned to
MAR or if while travelling it comes on either
steady or blinking (along with a message on the
multifunctional display, where provided).
The operation of the
Uwarning light may be
checked by the traffic control authorities using
specific devices. Always comply with the traffic
regulations in force in the country where you are
driving.
IMPORTANT After eliminating the failure, to check the
system completely, Abarth Dealerships run a bench test
and, if necessary, road tests which may require a long
journey.

TYRE PRESSURE MONITORING
SYSTEM (TPMS)
(for versions/markets where provided)
The car may be equipped with a tyre pressure
monitoring system (T.P.M.S.). This system comprises a
radio frequency transmitter fitted to each wheel (on the
rim inside the tyre), which is able to send information
on the pressure of each tyre to the control unit.
Take the greatest of care when checking
or restoring the tyre pressures. If the
pressure is too high, road hold is compromised,
there is more demand on the suspension and
wheels, and the tyres wear abnormally.
WARNING
Tyre pressure should be checked when
the tyres are cold; if, for whatever
reason, you check the pressure when the tyres
are hot, do not reduce the pressure even if it is
higher than the recommended value, but check
again when the tyres are cold.
WARNING
IMPORTANT NOTES ABOUT THE TPMS
SYSTEM
The fault indications are not stored and will therefore
not be displayed after the engine has been switched off
and then on again. If the fault conditions persist, the
control unit will send the relative indications to the
instrument panel only after the vehicle has been in
motion for a short time.
The presence of the TPMS does not
exonerate the driver from regularly
checking the pressure of the tyres and the spare
wheel (see “Wheels” in the “Maintenance and
care” section).
WARNING
The TPMS is not able to warn you of
sudden tyre pressure losses (for example
when a tyre bursts). In this case, stop the car,
braking with care and avoiding sharp steering
actions.

CONTENTS
Replacing the normal tyres with winter
tyres and vice versa requires an
inspection of the TPMS, which should be carried
out only by an Abarth Dealership.
WARNING
The TPMS requires the use of specific
equipment. Contact an Abarth
Dealership to find out which accessories are
compatible with the system (wheels, hub caps
etc.). The use of other accessories may affect
the normal operation of the system.
WARNING
Tyre inflation pressure may vary
according to outdoor temperature. The
TPMS system may temporarily indicate
insufficient pressure. In this case, check the tyre
pressures with the tyres cold and, if necessary,
pump them up.
WARNING
.If the vehicle is fitted with TPMS, tyre
and wheel fitting/removal operations
require specific precautions. To prevent damage
or incorrect sensor refitting, contact an Abarth
Dealership to have tyre and/or
rim changed.
WARNING
If the vehicle is fitted with TPMS, when
a tyre is removed, it is advisable to
replace the rubber gasket for the valve. Contact
an Abarth Dealership.
WARNING
Strong radio-frequency interference
could inhibit the correct operation of
the TPMS system.
This condition will be indicated by a message on
the reconfigurable multfunction display. The
message will disappear automatically as soon as
the interference ceases to disturb the system.

DRIVING MODES
The activation of “Sport” driving mode is indicated by
the switching on of the “S” symbol on the lower right
area of the reconfigurable multifunction display, as
shown in fig. 92-93.
When “Normal” mode is selected, no messages or
symbols are shown on the display, fig. 94-95.“MANETTINO ABARTH” CAR
DYNAMIC CONTROL SYSTEM
(DSS - Driving Sport Switch)
This device allows, using switch A-fig. 91, two response
modes to be selected according to driving style and
road conditions.
S = Sport (mode for sports driving)
N = Normal (mode for driving in normal conditions)
After being operated, the lever A always returns to the
central position.
The device also acts on the car dynamic control systems
(instrument panel, steering, engine, TTC and ASR
systems).

Logic for car dynamic control system
management with “Normal” mode
When the “Normal” driving mode is activated, the car
dynamic control systems intervene with the following
logic:
❒ASR system: calibration for normal driving conditions.
❒TTC system: disabled.
❒Steering: calibration for comfort in normal driving
conditions.
❒Engine: standard adjustment for normal driving
conditions.
TURNING “Sport” MODE ON/OFF
Engagement
To turn the “Sport” driving mode on, move the lever A-
fig. 91 forward to letter “S”. Keep the lever in this
position for at least half a second and in any case until
the symbol “S” or the word “SPORT” appears on the
reconfigurable multifunction display (see fig. 92-93).
After release, the lever A will return to the central
position.

Logic for car dynamic control system
management with “Sport” mode
When the “Sport” driving mode is activated, the car
dynamic control systems intervene with the following
logic:
❒ASR system: less intrusive calibration with
intervention thresholds that allow freer and sportier
drive.
❒TTC system: enabled for particularly effective and
sporty driving of the car.
❒Steering: calibration for sports driving.
❒Engine: sports adjustment with quicker response of
the accelerator pedal.
Disengagement
To turn the “Sport” driving mode off and return to
“Normal” mode, move the lever A-fig. 91 backwards to
letter “N”. Keep the lever in this position for at least
half a second and in any case until the symbol “S” or the
word “SPORT” disappears from the reconfigurable
multifunction display (see fig. 94-95).
After release, lever A returns to the central position.
