2019 FIAT 500X wheel torque

ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
DTC (Drag Torque Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
DST (Dynamic Steering Torque);
ERM (Electronic Rollover Mitigation);
TSC (Trailer Sway Control).
For the operation of the systems, see
the following description.
ABS (Anti-lock Braking
System)
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the vehicle
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.The system also improves control and
stability of the vehicle when braking on
a surface where the grip of the left and
right wheels varies, or on corners.
The Electronic Braking Force
Distribution (EBD) system completes
the system allowing the brake force to
be distributed between the front and
rear wheels.
System intervention
The driver can feel that the ABS system
has come into action because the
brake pedal pulsates slightly and the
system gets noisier: this is entirely
normal with the system operating.

DTC (Drag Torque
Control) SYSTEM
The DTC (Drag Torque Control) system
prevents the drive wheels from possibly
locking, which could happen, for
example, if the accelerator pedal is
released suddenly or in the case of a
sudden downshifting in conditions of
poor grip. In this conditions, the engine
braking effect could cause the drive
wheels to slip, resulting in a loss of car
stability. In these situations, the DTC
system intervenes, restoring torque to
the engine in order to conserve car
stability and increase car safety.
ESC (Electronic Stability
Control) SYSTEM
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the vehicle’s
understeer and oversteer, distributing
the brake force on the wheels
appropriately. The torque supplied by
the engine can also be reduced in order
to maintain control of the vehicle.
The ESC system uses sensors installed
on the vehicle to determine the
trajectory that the driver intends to
follow and compares it with the
vehicle’s effective trajectory. When the
real trajectory deviates from the desired
trajectory, the ESC system intervenes to
counter the vehicle’s understeer or
oversteer.
Oversteer: occurs when the vehicle is
turning more than it should according
to the angle of the steering wheel.
Understeer: occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.

TC (Traction Control)
SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on
one or more drive wheels. Depending
on the slipping conditions, two different
control systems are activated:
if the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine;
if the slipping only involves one of the
drive wheels, the BLD (Brake Limited
Differential) function is activated,
automatically braking the wheel which
is slipping (the behaviour of a
self-locking differential is simulated).
This will increase the engine torque
transferred to the wheel which isn't
slipping. This function remains active
even if the "Systems partially disabled"
and "Systems disabled" modes are
selected (see description in the
following pages).
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
PBA (Panic Brake
Assist) SYSTEM
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The system detects emergency braking
by monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the PBA system therefore
completes the ABS.
Maximum assistance from the PBA
system is obtained by pressing the
brake pedal very quickly. In addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most
out of the system. Do not reduce
pressure on the brake pedal until
braking is not necessary anymore.
The PBA system is deactivated when
the brake pedal is released.
48) 49) 50)
HSA (Hill Start Assist)
SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: vehicle stationary on a roadtransmission in neutral or gear other
than reverse engaged;
downhill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and reverse
gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the engine
torque necessary for starting is
reached, or in any case for a maximum
of 2 seconds, allowing your right foot to
be moved easily from the brake pedal
to the accelerator.
When the 2 seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage, the typical
mechanical brake release noise can be
heard, indicating that the car is about to
move.

DST SYSTEM (Dynamic
Steering Torque)
The DST function uses the integration
of the ESC system with the electric
power steering to increase the safety
level of the whole vehicle.

SAFETY
43) 44) 45) 46) 47)with a gradient higher than 5%, engine
running, brake pressed and

In critical situations (braking on surfaces
with different grip conditions), through
the DST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
53)
ERM (Electronic Rollover
Mitigation) SYSTEM
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It is
not possible to avoid tendency to roll
over if the phenomenon is due to
reasons such as driving on high side
gradients, collision with objects or other
vehicles.
54)
TSC (Trailer Sway
Control) SYSTEM
The system employs a series of sensors
located on the vehicle to identify
excessive swerving of the trailer and
take the necessary precautions to
eliminate it.
To counteract the effect of trailer sway,
the system can reduce the engine
power and intervene on the wheels
involved. The TSC system activates
automatically once excessive sway of
the trailer is detected.
System intervention
When the system is active, the
warning light flashes on the
instrument panel, the engine power is
reduced and braking can be felt on the
individual wheels, following the attempt
to eliminate the swerving of the trailer.
55) 56)
WARNING
31)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on
the current road conditions.32)To obtain the maximum efficiency of
the braking system, a bedding-in period of
about 500 km is needed: during this period
it is better to avoid sharp, repeated and
prolonged braking.
33)If the ABS intervenes, this indicates
that the grip of the tyres on the road is
nearing its limit: you must slow down to a
speed compatible with the available grip.
34)The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition of
the road.
35)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
36)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
37)For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
38)The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.
39)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
40)The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the safety
of others.

The acceptance by the system of the
requested driving mode is signalled by
the LED, located besides the symbol,
coming on, and by the corresponding
symbol appearing on the instrument
panel display.
When the engine is started, the system
usually maintains the driving mode that
was active before the engine was
stopped. For versions/markets where
provided, on start-up, the system is set
to the "Auto" mode.
"Auto" MODE
Recommended mode for normal
driving, aimed at comfort and safety in
normal grip and driving conditions. This
mode also reduces fuel consumption,
since it automatically disconnects the
transmission from the rear wheels if the
road and driving conditions allow it, in
addition to changing drive torque
distribution between the front and rear
axles.
Activation
Starting with the "All Weather" mode
active, turn the ring-nut anticlockwise
and hold it in this position for at least
half a second, until the relative LED
illuminates and the selected mode
appears on the display. The LED of the
mode selected previously will go out atthe same time. Once released, the
ring-nut returns to the central position.
Starting with the "Sport" mode active,
turn the ring-nut clockwise and hold it
in this position for at least half a
second, until the relative LED
illuminates and the selected mode
appears on the display. The LED of the
mode selected previously will go out at
the same time. Once released, the
ring-nut returns to the central position.
“All Weather” MODE
This driving mode is intended for safety
in poor vehicle grip conditions
(wet/slippery road surface, rain, snow).
It is also recommended for driving on
unpaved roads or off-road.
Activation
Starting with the "Auto" mode active,
turn the ring-nut clockwise and hold it
in this position for at least half a
second, until the relative LED
illuminates and the selected mode
appears on the display. The LED of the
mode selected previously will go out at
the same time. Once released, the
ring-nut returns to the central position.
Starting from the active "Sport" mode,
turn the ring nut anticlockwise, keeping
it in this position for at least half a
second, and in any case until the
relevant LED turns on, and the selectedmode is shown on the display. The LED
of the mode selected previously will go
out at the same time. Once released,
the ring-nut returns to the central
position.
"Sport" MODE
This mode gives the most enjoyable
sporty driving experience, however, it
increases fuel consumption. Traction is
optimised to improve the car's
road-holding, also when cornering.
Activation
Starting with the "Auto" mode active,
turn the ring-nut anticlockwise and hold
it in this position for at least half a
second, until the relative LED
illuminates and the selected mode
appears on the display. The LED of the
mode selected previously will go out at
the same time. Once released, the
ring-nut returns to the central position.
Starting with the "All Weather" mode
active, turn the ring nut clockwise,
keeping it in this position for at least half
a second, and in any case until the
relevant LED turns on, and the selected
mode is shown on the display. The LED
of the mode selected previously will go
out at the same time. Once released,
the ring-nut returns to the central
position.

STARTING AND DRIVING

55)Have interventions on the bumper in
the area of the sensors carried out only by
a Fiat Dealership. Interventions on the
bumper that are not carried out properly
may compromise the operation of the
parking sensors.
56)Only have the bumpers repainted or
any retouches to the paintwork in the area
of the sensors carried out by a Fiat
Dealership. Incorrect paint application
could affect the operation of the parking
sensors.
57)The rear sensors may provide a false
reading, interpreting the tow hook ball
assembly and the respective attachment as
an obstacle in the area behind the car.LANE ASSIST
SYSTEM (lane
crossing warning)
DESCRIPTION
58) 59) 60) 61) 62) 63)
The Lane Assist system makes use of a
camera located on the windscreen to
detect the lane limits and calculate the
position of the car within such limits, in
order to make sure that it remains
inside the lane.
When the one of the lane lines is
detected and the car crosses it without
the awareness of the driver (direction
indicator off), the Lane Assist system
provides a tactile warning by applying
torque to the steering wheel (vibration),
thus advising the driver that he must
take an action to remain in the lane.
IMPORTANT The torque applied to the
steering wheel by the system is
sufficient for the driver to notice it, but
always limited, so that they can easily
override it, and the driver always
maintains control of the car. The driver
can therefore turn the steering wheel as
required at all times.
If the vehicle continues going beyond
the line of the lane without any
intervention from the driver, the
warning light (or the icon on the
display) will be displayed on the
instrument panel to urge the driver to
bring the vehicle back into the limits of
the lane.
IMPORTANT The system monitors the
presence of the driver's hands on the
steering wheel. If they are not detected,
the system emits an acoustic warning
and deactivates until it is reactivated by
pressing the dedicated button (see
description below).
SYSTEM ON/OFF
The Lane Assist system can be
enabled/disabled using button A
fig. 106, located on the left stalk.
Each time the engine is started, the
system keeps the activation status
there was when it was previously
switched off.
