Super-LSD operation
Straight ahead driving
When driving straight, the right and left
side gears rotate at the same speed,
and the pinion and side gears rotate
together with the differential gear case.
Input force from the ring gear is
transmitted to the pinion gears via the
gear case and to the drive shaft via the
side gears. Due to this, a speed
difference between right and left in the
differential does not occur.
Differential operation
If the rotation speed between the right
and left wheels becomes different
(during normal driving), the pinion gears
rotate together while revolving around
the center axle of the drive shaft,
thereby absorbing the difference in
rotation speed. This mechanism serves
as a differential.
Limited-slip operation
If the differential encounters a condition
requiring limited-slip control such as
wheel spin, thrust force acts on the side
gears due to the reaction force from the
meshing of the pinion and side gears.
This thrust force presses the side gears
against the taper ring, generating
friction between the side gear cone and
the taper ring and reducing the torque
of the slipping wheel.The reduced torque is transmitted
without change to the wheel with higher
traction, and the limited slip differential
function is provided. The torque
transmitted to the wheel with higher
traction is proportionate to the input
torque of the ring gear.
HLA (Hill Launch Assist)
FUNCTION
Hill Launch Assist (HLA) is a function
which assists the driver in accelerating
from a stop while on a slope. When the
driver releases the brake pedal and
depresses the accelerator pedal while
on a slope, the function prevents the
vehicle from rolling. The braking force is
maintained automatically after the brake
pedal is released on a steep grade.
For vehicles with a manual
transmission, Hill Launch Assist
operates on a downward slope when
the shift lever is in the reverse (R)
position, and on an upward slope when
the shift lever is in a position other than
the reverse (R) position.
For vehicles with an automatic
transmission, Hill Launch Assist
operates on a downward slope when
the selector lever is in the reverse (R)
position, and on an upward slope when
the selector lever is in a forward gear.
IMPORTANT Hill Launch Assist does
not operate on a gentle slope. Inaddition, the gradient of the slope on
which the system will operate changes
depending on the vehicle's load.
IMPORTANT Hill Launch Assist does
not operate if the parking brake is
applied, the vehicle has not stopped
completely, or the clutch pedal is
released.
IMPORTANT While Hill Launch Assist is
operating, the brake pedal may feel stiff
and vibrate, however, this does not
indicate a malfunction.
IMPORTANT Hill Launch Assist does
not operate while the TCS/DSC
indicator light is illuminated. Refer to
“Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.
IMPORTANT Hill Launch Assist (HLA)
does not turn off even if the DSC OFF
switch is pressed to turn off the
TCS/DSC.
IMPORTANT For vehicles with an
automatic transmission although the Hill
Launch Assist does not operate during
idling stop, the vehicle roll prevention
function operates to prevent vehicle roll.
IMPORTANT Do not rely completely on
Hill Launch Assist. Hill Launch Assist is
an auxiliary device for accelerating from
a stop on a slope. The system only

Unfastening the seat belt
Depress the button 1 fig. 63 on the seat
belt buckle. If the belt does not fully
retract, pull it out and check for kinks or
twists. Then make sure it remains
untwisted as it retracts.
IMPORTANT If a belt does not fully
retract, inspect it for kinks and twists. Ifit is still not retracting properly, have it
inspected: contact an Abarth
Dealership.
IMPORTANT Always wear the seat belt
with it correctly routed in its guide 1
fig. 64. Wearing a seat belt without the
seat belt routed in its guide is
dangerous because the seat belt would
not be able to provide adequate
protection in an accident, which could
result in serious injury.
SEAT BELT WARNING
SYSTEMS
If it detects that the occupant seat belt
is unfastened, the warning light or beep
alerts the occupant.
Refer to “Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.Refer to “Seat belt warning beep” in
“Knowing the instrument panel”
chapter.
WARNING
79)Always wear your seat belt and make
sure all occupants are properly restrained.
Not wearing a seat belt is extremely
dangerous. During a collision, occupants
not wearing seat belts could hit someone
or things inside the vehicle or even be
thrown out of the vehicle. They could be
seriously injured or even killed. In the same
collision, occupants wearing seat belts
would be much safer.
80)Do not wear twisted seat belts. Twisted
seat belts are dangerous. In a collision, the
full width of the belt is not available to
absorb the impact. This puts more force on
the bones beneath the belt, which could
cause serious injury or death. So, if your
seat belt is twisted, you must straighten
the seat belt to remove any twists and to
allow the full width of the belt to be used.
81)Never use one seat belt on more than
one person at a time. Using one seat belt
for more than one person at a time is
dangerous. A seat belt used in this way
cannot spread the impact forces properly
and the two passengers could be crushed
together and seriously injured or even
killed. Never use one belt for more than
one person at a time and always operate
the vehicle with each occupant properly
restrained.

SAFETY
SEAT BELT
PRETENSIONER AND
LOAD LIMITING
SYSTEMS
PRETENSIONERS
88) 89) 90) 91)
For optimum protection, the driver and
passenger seat belts are equipped with
pretensioner and load limiting systems.
For both these systems to work
properly you must wear the seat belt
properly.
When a collision is detected, the
pretensioners deploy simultaneously
with the air bags. For deployment
details, refer to the “SRS air bag
deployment criteria” paragraph in this
chapter.
The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have fired they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.
Refer to “Warning lights and messages”
and “Warning sound is activated”
paragraph in “Knowing the instrument
panel” chapter.
In addition, the pretensioner system for
the passenger, like the front and side
passenger air bag, is designed to onlydeploy when the passenger occupant
classification sensor detects a
passenger sitting on the passenger's
seat. For details, refer to the passenger
occupant classification sensor.
IMPORTANT The pretensioner system
may not operate depending on the type
of the collision. For details, refer to the
“SRS Air Bag deployment criteria”
paragraph.
IMPORTANT Some smoke (non-toxic
gas) will be released when the air bags
and pretensioners deploy. This does
not indicate a fire. This gas normally
has no effect on occupants, however,
those with sensitive skin may
experience slight skin irritation. If
residue from the deployment of the air
bags or the pretensioner system gets
on the skin or in the eyes, wash it off as
soon as possible.
LOAD LIMITER
The load limiting system releases belt
webbing in a controlled manner to
reduce belt force on the occupant's
chest.
While the most severe load on a seat
belt occurs in frontal collisions, the load
limiter has an automatic mechanical
function and can activate in any
accident mode with sufficient occupant
movement.Even if the pretensioners have not fired,
the load limiting function must be
checked by Abarth Dealership.
WARNING
88)Wear seat belts only as recommended
in this Owner Handbook. Incorrect
positioning of the driver and passenger
seat belts is dangerous. Without proper
positioning, the pretensioner and load
limiting systems cannot provide adequate
protection in an accident and this could
result in serious injury. For more details
about wearing seat belts, refer to
"Fastening the seat belts".
89)Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended. Always have an
expert repairer: contact an Abarth
Dealership immediately for seat belt
pretensioners and air bags inspections
after any collision. Like the air bags, the
seat belt pretensioners and load limiters will
only function once and must be replaced
after any collision that caused them to
deploy. If the seat belt pretensioners and
load limiters are not replaced, the risk of
injury in a collision will increase.
90)Do not modify the components or
wiring, or use electronic testing devices on
the pretensioner system. Modifying the
components or wiring of the pretensioner
system, including the use of electronic
testing devices is dangerous. You could
accidentally activate it or make it inoperable
which would prevent it from activating in an
accident. The occupants or repairers could
be seriously injured.

SAFETY
Proceed as follows:
open the convertible top;
make sure the ignition is switched
off;
slide the passenger seat as far back
as possible. You may need to move the
seat forward slightly and recline the
back of the seat, in order to assist in
the fittment of some child-restraint
systems;
make sure the seatback is securely
latched by pushing it back until it is fully
locked;
expand the area between the seat
bottom and the seatback slightly to
verify the locations of the ISOFIX anchor
.
IMPORTANT The markings above the
ISOFIX anchors indicate the locations of
the ISOFIX anchors for the attachment
of a child restraint system.
secure the child restraint system
using the ISOFIX anchor, following the
child restraint system manufacturer's
instruction;
switch the ignition ON and make
sure the OFF passenger air bag
deactivation indicator light
fig. 72 illuminates after installing a child
restraint system on the passenger seat
(see “Passenger Air Bag deactivation
indicator lights” paragraph). If the
passenger air bag OFF deactivation
indicator light does not illuminate,
remove the child restraint system,
switch the ignition to OFF, and then
reinstall the child restraint system;
if your child restraint system came
equipped with a tether, that probably
means it is very important to properly
secure the tether for child safety. Please
carefully follow the child restraint
system manufacturer's instructions
when installing tethers.
WARNING
92)Use the correct size child-restraint
system. For effective protection in vehicle
accidents and sudden stops, a child must
be properly restrained using a seat belt or
child-restraint system depending on age
and size. If not, the child could be seriously
injured or even killed in an accident.
93)Follow the manufacturer's instructions
and always keep the child-restraint system
buckled down. An unsecured
child-restraint system is dangerous. In a
sudden stop or a collision it could move
causing serious injury or death to the child
or other occupants. Make sure any
child-restraint system is properly secured in
place according to the child-restraint
system manufacturer's instructions. When
not in use, remove it from the vehicle or
fasten it with a seat belt, or latch it down to
BOTH ISOFIX anchors, and attach the
corresponding tether anchor.

vehicle was hit.
The side air bag inflates quickly to
reduce injury to the driver or
passenger's head and chest caused by
directly hitting interior parts such as a
door or window. For more details about
air bag deployment, refer to "SRS Air
Bag deployment criteria" in this chapter.
In addition, the passenger side bag is
designed to only deploy when the
passenger occupant classificationsensor detects a passenger sitting on
the passenger's seat.

First, please read "Supplemental
Restraint System (SRS) Precautions"
carefully.
Passenger occupant classification
sensor
Your vehicle is equipped with a
passenger occupant classification
sensor as a part of the supplementary
restraint system. This sensor is
equipped in the passenger's seat
cushion. This sensor measures the
electrostatic capacity of the
passenger's seat.
The SAS unit is designed to prevent the
passenger front and side air bags and
seat belt pretensioner system fromdeploying if the passenger air bag
deactivation indicator light turns on.
To reduce the chance of injuries caused
by deployment of the passenger air
bag, the system deactivates the
passenger front and side air bags and
also the seat belt pretensioner system
when the passenger air bag
deactivation indicator light turns on.
This system shuts off the passenger
front and side air bags and seat belt
pretensioner system, so make sure the
passenger air bag deactivation indicator
light turns on.
The air bag/seat belt pretensioner
system warning light flashes and the
passenger air bag deactivation indicator
light illuminates if the sensors have a
possible malfunction. If this happens,
the passenger front and side air bags
and seat belt pretensioner system will
not deploy.
IMPORTANT If a passenger is seated
as shown in the following fig. 82 the
passenger occupant classification
sensor cannot detect a passenger
sitting on the passenger's seat correctly
and the deployment/non-deployment of
the air bags cannot be controlled as
indicated in the passenger air bag
deactivation indicator light on/off
condition chart.
Passenger air bag deactivation

These indicator lights fig. 83 turn on to
remind you that the passenger front
and side air bags and seat belt
pretensioner will or will not deploy
during a collision.

simultaneously.
EMERGENCY STOP
SIGNAL SYSTEM
The system turns off when it determines
that the brake pedal is released or that
an emergency braking situation no
longer exists based on the reduced
vehicle speed.
If the system determines that such a
situation is occurring, it flashes all the
direction indicators rapidly to caution
the driver of the vehicle following behind
your vehicle of the sudden braking
situation.
This system is designed to determine
whether you are depressing the brake
pedal with greater force than during
normal braking such as in a situation
requiring emergency braking.
If you bring your vehicle to a complete
stop while all the direction indicators are
flashing rapidly, the rapid flashing of all
the direction indicators changes back
to the normal flashing pattern.The emergency stop signal system
does not operate at vehicle speeds
under about 60 km/h.
If the brake pedal is depressed while
driving on slippery roads, the
emergency stop signal system could
operate causing all the direction and
lane change indicators to flash.
