2017 Abarth 124 Spider change wheel

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
75

operates for about two seconds and
therefore, relying only on the system,
when accelerating from a stop is
dangerous because the vehicle may
move (roll) unexpectedly and cause an
accident. The vehicle could roll
depending on the vehicle's load or if it
is towing something. In addition, for
vehicles with a manual transmission,
the vehicle could still roll depending on
how the clutch pedal or the accelerator
pedal is operated. Always confirm the
safety around the vehicle before starting
to drive the vehicle.
WARNING
76)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tire pressure, including for the spare
wheel, and correct maintenance: the
system is not used to signal a possible fault
to a tire. Tire pressure must be checked
with tires rested and cold. Should it
become necessary for whatever reason to
check pressure with warm tires, do not
reduce pressure even though it is higher
than the prescribed value. Repeat the
check when the tires are cold.
77)Replacing the normal tires with winter
tires and vice versa requires an inspection
of the TPMS, which should be carried out
only by an Abarth Dealership.
78)Changes in outside temperature may
cause tire pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case check the tire
inflation pressure with the tires cold and, if
necessary top up the inflation pressure.
OCCUPANT
PROTECTION
SYSTEMS
The most important safety equipment
of the vehicle comprise the following
protection systems:
seat belts;
SBA (Seat Belt Alert) system;
head restraints;
child restraint systems;
front air bags and side air bags.
Read the information given the following
pages with the utmost care.
It is of fundamental importance that the
protection systems are used in the
correct way to guarantee the maximum
possible safety level for the driver and
the passengers.

SAFETY

N (Neutral)
141)
In N, the wheels and transmission are
not locked. The vehicle will roll freely
even on the slightest incline unless the
parking brake or brakes are on.
IMPORTANT Do not shift into N when
driving the vehicle. Doing so can cause
transaxle damage. Apply the parking
brake or depress the brake pedal
before moving the selector lever from N
to prevent the vehicle from moving
unexpectedly.
D (Drive)
D is the normal driving position. From a
stop, the transmission will automatically
shift through a 6-gear sequence.
M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the selector lever. Refer to
“Manual shift mode”.
SHIFT-LOCK SYSTEM
The shift-lock system prevents shifting
out of P unless the brake pedal is
depressed.
To shift from P:
depress and hold the brake pedal;
start the engine;
press and hold the lock-release
button;
move the selector lever.
When the ignition is switched to ACC or
the ignition is switched off, the selector
lever cannot be shifted from P.
The ignition cannot be switched to OFF
if the selector lever is not in P.
SHIFT-LOCK OVERRIDE
If the selector lever will not move from P
using the proper shift procedure,
continue to hold down the brake pedal.
Proceed as follows:
remove the shift-lock override cover
using a cloth-wrapped flat head
screwdriver fig. 87;
insert a screwdriver and push it
down;
press and hold the lock-release
button and move the selector lever;
take the vehicle to an Abarth
Dealership.For some versions
Proceed as follows:
press the lock-release button with
the button pressed fig. 88;
move the selector lever;
take the vehicle to an Abarth
Dealership.
MANUAL SHIFT MODE
To change to manual shift mode, shift
theleverfromDtoM.Toreturnto
automatic shift mode, shift the lever
fromMtoD.
IMPORTANT Changing to manual shift
mode while driving will not damage the
transmission.
IMPORTANT If you change to manual
shift mode when the vehicle is stopped,
the gear may shift to M1.

STARTING AND OPERATING

WARNING
139)Always set the selector lever to P and
set the parking brake. Only setting the
selector lever to the P position without
using the parking brake to hold the vehicle
is dangerous. If P fails to hold, the vehicle
could move and cause an accident.
140)If the engine is running faster than
idle, do not shift from N or P into a driving
gear. It's dangerous to shift from N or P
into a driving gear when the engine is
running faster than idle. If this is done, the
vehicle could move suddenly, causing an
accident or serious injury.
141)Do not shift into N when driving the
vehicle. Shifting into N while driving is
dangerous. Engine braking cannot be
applied when decelerating which could
lead to an accident or serious injury.
142)Keep your hands on the steering
wheel rim when using fingers on the
steering shift switches. Putting your hands
inside the rim of the steering wheel when
using the steering shift switches is
dangerous. If the driver's air bag were to
deploy in a collision, your hands could be
impacted causing injury.
143)Do not use engine braking on slippery
road surfaces or at high speeds. Shifting
down while driving on wet, snowy, or
frozen roads, or while driving at high
speeds causes sudden engine braking,
which is dangerous. The sudden change in
tire speed could cause the tires to skid.
This could lead to loss of vehicle control
and an accident.144)Do not let the vehicle move in a
direction opposite to the direction selected
by the selector lever. Do not let the vehicle
move backward with the selector lever in a
forward position, or do not let the vehicle
move forward with the selector lever in the
reverse position. Otherwise, the engine
may stop, causing the loss of the power
brake and power steering functions, and
make it difficult to control the vehicle which
could result in an accident.
SPORT MODE
(where provided)
DRIVE SELECTION
Drive selection is a system to switch the
vehicle's drive mode. When theSPORT
mode is selected, vehicle's response
against accelerator operation is
enhanced.
IMPORTANT Do not use theSPORT
mode when driving on slippery roads
such as wet or snow-covered roads. It
may cause tyre slipping.
