ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
TCS (Traction Contol System);
DSC (Dynamic Stability Control);
Active bonnet (active pedestrian
protection).
For the operation of the systems, see
the following pages.
ABS SYSTEM (Antilock
Brake System)
65) 66) 67) 68)
The ABS control unit continuously
monitors the speed of each wheel. If
one wheel is about to lock up, the ABS
responds by automatically releasing
and reapplying that wheel's brake.
The driver will feel a slight vibration in
the brake pedal and may hear a
chattering noise from the brake system.
This is normal ABS system operation.
Continue to depress the brake pedal
without pumping the brakes.
The warning light turns on when the
system has a malfunction. Refer to
“Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.
NOTE Braking distances may be longer
on loose surfaces (snow or gravel, forexample) which usually have a hard
foundation. A vehicle with a normal
braking system may require less
distance to stop under these conditions
because the tires will build up a wedge
of surface layer when the wheels skid.
NOTE The sound of the ABS operating
may be heard when starting the engine
or immediately after starting the vehicle,
however, it does not indicate a
malfunction.
TCS SYSTEM (Traction
Control System)
69) 70) 71)
The Traction Control System (TCS)
enhances traction and safety by
controlling engine torque and braking.
When the TCS detects driving wheel
slippage, it lowers engine torque and
operates the brakes to prevent loss of
traction.
This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.
The warning light turns on when the
system has a malfunction. Refer to
“Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.TCS / DSC indicator light
The
indicator light stays on for a few
seconds when the ignition is switched
ON.
If the TCS or DSC is operating, the
indicator light flashes.
If the
light stays on, the TCS, DSC or
the brake assist system may have a
malfunction and they may not operate
correctly. Contact an Abarth Dealership.
IMPORTANT In addition to the warning
light flashing, a slight labouring sound
will come from the engine. This
indicates that the TCS/DSC is
operating properly.
IMPORTANT On slippery surfaces, such
as fresh snow, it will be impossible to
achieve high rpm when the TCS is on.
DSC SYSTEM (Dynamic
Stability Control)
72) 73) 74)
The Dynamic Stability Control (DSC)
automatically controls braking and
engine torque in conjunction with
systems such as ABS and TCS to help
control side slip when driving on
slippery surfaces, or during sudden or
evasive manoeuvring, enhancing vehicle
safety. Refer to “ABS system (Antilock
Brake System)” and “TCS system
(Traction Control System)”.
68
SAFETY
DSC operation is possible at speeds
greater than 20 km/h.
The warning light turns on when the
system has a malfunction. Refer to
“Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.
NOTE The DSC may not operate
correctly unless the following are
observed:
use tires of the correct size specified
for your vehicle on all four wheels;
use tires of the same manufacturer,
brand and tread pattern on all four
wheels;
do not mix worn tires.
IMPORTANT The DSC may not operate
correctly when tire chains are used or a
temporary spare tire is installed
because the tire diameter changes.
TCS / DSC indicator light
The
indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light flashes.
If the light stays on, the TCS, DSC or
the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an Abarth
Dealership.DSC OFF indicator light
The
indicator light stays on for a few
seconds when the ignition is switched
ON. It also illuminates when the DSC
OFF switch is pressed and TCS/DSC is
switched off.
If the light remains illuminated and the
TCS/DSC is not switched off, contact
an Abarth Dealership. The DSC may
have a malfunction.
DSC OFF switch
Press the switch fig. 57 to turn off the
TCS/DSC. The
warning light in the
instrument cluster will illuminate.
Press the switch again to turn the TCS/
DSC back on. The DSC OFF indicator
light will turn off.
IMPORTANT When DSC is on and you
attempt to free the vehicle when it is
stuck, or drive it out of freshly fallen
snow, the TCS (part of the DSCsystem) will activate. Depressing the
accelerator will not increase engine
power and freeing the vehicle may be
difficult. When this happens, turn off the
TCS/DSC.
IMPORTANT If the TCS/DSC is off
when the engine is turned off, it
automatically activates when the
ignition is switched ON.
IMPORTANT Leaving the TCS/DSC on
will provide the best traction.
IMPORTANT If the switch is pressed
and held for 10 seconds or more, the
DSC OFF switch malfunction detection
function operates and the DSC system
activates automatically. The DSC OFF
indicator light turns off while the DSC
system is operative.
ACTIVE BONNET
PRECAUTIONS
75)
In the unlikely event that the vehicle
were to hit a pedestrian and a certain
amount of impact is applied to the front
of the vehicle, impact to the head of the
pedestrian if it were to hit the bonnet is
lessened by the rear area of the bonnet
raising instantly to maintain a wide
space between it and the parts in the
engine compartment.
If the sensor 1 fig. 58 installed to the
5705060301-12A-987AB
69
back of the front bumper detects a
certain amount of impact by a collision
with a pedestrian or other obstruction
while the vehicle is being driven at a
speed sufficient to activate the system,
the system is activated and the bonnet
is raised (3 = active bonnet warning
light/4=electronic control unit).
IMPORTANT Do not touch the actuator
2 fig. 58 directly after the active bonnet
has activated. Otherwise, it could result
in a burn as the actuator is hot directly
after the activation.
Operation and handlingAlways make sure that the bonnet is
closed completely before driving.
Otherwise, the system may not operate
normally.
The system may not operate for
about 8 seconds after the ignition is
switched ON.
Use tires of the same specified size
on all four wheels. If tires with different
sizes are used, the system may not
operate normally.
If something hits the area around the
front bumper, the sensor could be
damaged even if the active bonnet
does not activate. Contact an Abarth
Dealership to have the vehicle
inspected.
Do not remove or repair parts or
wiring for the active bonnet. In addition,
do not test the system’s circuitry using
an electric tester. Otherwise, the active
bonnet may activate mistakenly or not
operate normally. Contact an Abarth
Dealership when repairs or replacement
servicing is required.
Do not replace the front bumper,
bonnet, suspension, aero parts, or
wheels with non-genuine FCA parts.
Otherwise, the system may not operate
normally.
Do not install non-genuine FCA
accessories to the front bumper. In
addition, do not install objects on thebonnet. Otherwise, the system may not
operate normally.
Do not close the bonnet excessively
or apply a load to the actuator.
Otherwise, the actuator could be
damaged and cause the system to not
operate normally.
Do not modify the suspension. If the
vehicle height or the damping force of
the suspensions is changed, the
system may not operate normally.
When equipping parts, contact an
Abarth Dealership. If parts are installed
incorrectly, the active bonnet may not
activate normally due to the inability to
detect an impact.
When disposing of the vehicle,
contact an Abarth Dealership. If the
vehicle is not handled correctly, it could
result in injury.
The active bonnet cannot be reused
if it has been activated. Contact an
Abarth Dealership.
If the active bonnet activates
The active bonnet activates under the
following conditions:
if the front of the vehicle hits a
pedestrian or obstruction while the
vehicle is being driven at a speed
sufficient to activate the system, the
system will activate if a certain amount
of impact is applied in a collision even
though no trace may remain on the
5803060100-L12-888AB

SAFETY
When changing tires yourself:ifyou
or someone else changes tires, you or
someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration:
after tires have been changed, switch
the ignition ON, then back to ACC or
OFF;
wait for about 15 minutes;
after about 15 minutes, drive the
vehicle at a speed of at least 25 km/h
for 10 minutes and the tire pressure
sensor ID signal code will be registered
automatically.
IMPORTANT If the vehicle is driven
within about 15 minutes of changing
tires, the
warning light will flash
because the sensor ID signal code
would not have been registered. If this
happens, park the vehicle for about
15 minutes, after which the sensor ID
signal code will register upon driving the
vehicle for 10 minutes.
Replacing tires and wheels
IMPORTANT When replacing/repairing
the tires or wheels or both, have the
work done by an Abarth Dealership, or
the tire pressure sensors may be
damaged.
IMPORTANT The wheels equipped on
your vehicle are specially designed for
installation of the tire pressure sensors.Do not use non-genuine wheels,
otherwise it may not be possible to
install the tire pressure sensors.
Be sure to have the tire pressure
sensors installed whenever tires or
wheels are replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are
possible:
the tire pressure sensor is removed
from the old wheel and installed to the
new one;
the same tire pressure sensor is used
with the same wheel. Only the tire is
replaced;
a new tire pressure sensor is installed
to a new wheel.
IMPORTANT The tire pressure sensor
ID signal code must be registered when
a new tire pressure sensor is
purchased. For purchase of a tire
pressure sensor and registration of the
tire pressure sensor ID signal code,
consult an Abarth Dealership.
IMPORTANT When reinstalling a
previously removed tire pressure sensor
to a wheel, replace the grommet (seal
between valve body/sensor and wheel)
for the tire pressure sensor.MECHANICAL LIMITED
SLIP DIFFERENTIAL
Your vehicle is equipped with a
mechanical limited slip differential. In
particular this vehicle adopts a
super-LSD which guarantees improved
vehicle traction and handling.
A super-LSD with a low torque bias
ratio (*) has been adopted to improve
performance when starting from a
standstill, driving straight-ahead and
response.
(*)Torque bias ratio: when a wheel
slips due to a low-traction surface, the
LSD provides proportionally more
torque to the opposite wheel. The
torque bias ratio is the ratio of torque
supplied to the right and left wheels in
such cases, and represents the
performance capability of the LSD.
The super-LSD is a torque-sensing type
that provides improved driving stability
due to the following characteristics:
low torque bias ratio provides
improved controllability (torque bias
ratio: 2.0);
creation of initial torque provides
improved starting from a standstill and
acceleration/deceleration response, and
driving straight-ahead (initial torque:
49 Nm);
simplified construction provides
weight reduction.

SAFETY
82)Do not operate a vehicle with a
damaged seat belt. Using a damaged seat
belt is dangerous. An accident could
damage the belt webbing of the seat belt in
use. A damaged seat belt cannot provide
adequate protection in a collision. Contact
an Abarth Dealership to inspect all seat belt
systems in use during an accident before
they are used again.
83)Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended. Always have an
expert repairer, we recommend an Abarth
Dealership immediately inspect the seat
belt pretensioners and air bags 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.
84)Positioning the shoulder portion of the
seat belt. Improper positioning of the
shoulder portion of the seat belt is
dangerous. Always make sure the shoulder
portion of the seat belt is positioned across
your shoulder and near your neck, but
never under your arm, on your neck, or on
your upper arm.
85)Positioning the lap portion of the seat
belt. The lap portion of the seat belt worn
too high is dangerous. In a collision, this
would concentrate the impact force directly
on the abdominal area, causing serious
injury. Wear the lap portion of the belt
snugly and as low as possible.86)Instructions for use of seat belt
assemblies. Seat belts are designed to
bear upon the bony structure of the body,
and should be worn low across the front of
the pelvis or the pelvis, chest and
shoulders, as applicable; wearing the lap
section of the belt across the abdominal
area must be avoided. Seat belts should
be adjusted as firmly as possible,
consistent with comfort, to provide the
protection for which they have been
designed. A slack belt will greatly reduce
the protection afforded to the wearer. Care
should be taken to avoid contamination of
the webbing with polishes, oils and
chemicals, and particularly battery acid.
Cleaning may safely be carried out using
mild soap and water. The belt should be
replaced if webbing becomes frayed,
contaminated or damaged. It is essential to
replace the entire assembly after it has
been worn in a severe impact even if
damage to the assembly is not obvious.
Belts should not be worn with straps
twisted. Each belt assembly must only be
used by one occupant; it is dangerous to
put a belt around a child being carried on
the occupant's lap.
87)No modifications or additions should
be made by the user which will either
prevent the seat belt adjusting devices
from operating to remove slack, or prevent
the seat belt assembly from being adjusted
to remove slack.SBA SYSTEM
(Seat Belt Alert)
SEAT BELT WARNING
LIGHT
The LED on dashboard trim turns on if
the driver or passenger's seat is
occupied and the seat belt is not
fastened with the ignition switched ON.
If the driver or passenger's seat belt is
unfastened (only when the passenger
seat is occupied) and the vehicle is
driven at a speed faster than about
20 km/h, the
LED flashes. After a
short time, the LED stops flashing, but
remains illuminated.
If a seat belt remains unfastened, the
LED flashes again for a given period of
time. In this case, fasten the seat belt.
If the driver or passenger's seat belt is
unfastened after the LED turns on, and
the vehicle speed exceeds 20 km/h, the
LED flashes again.

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.
