2016 FIAT TIPO 4DOORS traction control

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);
HHC (Hill Hold Control);
ERM (Electronic Rollover Mitigation);
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 ona 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 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 vehicle stability. In
these situations, the DTC system
intervenes, restoring torque to the
engine in order to conserve vehicle
stability and increase vehicle safety.
ESC (Electronic Stability
Control) SYSTEM
The ESC system improves the
directional control and stability of the
car 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 car 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.
45) 46) 47) 48) 49)
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 no longer necessary.
The PBA system is deactivated when
the brake pedal is released.
50) 51) 52)
HHC (Hill Hold Control)
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 roadwith a gradient higher than 5%, engine
running, brake pressed and
transmission 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 two seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage it is possible to hear a
typical mechanical brake release noise,
indicating the imminent movement of
the car.
53) 54)
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.

SAFETY

and rear axle may adversely affect
vehicle driveability, with the risk of losing
control of the vehicle and resulting
accidents.
SUGGESTIONS ABOUT
THE ROTATION OF THE
TYRES
The front and rear tyres are subject to
different loads and stress due to
steering, manoeuvres and braking. For
this reason they are subject to uneven
wear.
To resolve this problem, tyres should be
rotated at the appropriate time. Tyre
rotation means moving the wheels to a
different position, with respect to the
vehicle. The single wheel will therefore
operate on a different axle of the
vehicle.
Tyre rotation contributes to the
preservation of the grip and traction
performance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting a Fiat
Dealership.
WARNING
156)The road holding qualities of the car
also depend on the correct inflation
pressure of the tyres.
157)If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
158)If the tyres are "unidirectional", do not
switch tyres from the right-hand side of the
vehicle to the left-hand side, and vice
versa. This type of tyres can only be
switched from the front axle to the rear axle
and vice versa, keeping them on the same
side of the vehicle.
159)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
160)Travelling with partially or completely
deflated tyres can cause safety problems
and damage the concerned tyre beyond
repair.
IMPORTANT
58)Keep your speed down when snow
chains are fitted; do not exceed 50 km/h.
Avoid potholes, do not drive over steps or
sidewalks and do not drive long distances
over roads without snow, to avoid
damaging both your vehicle and the road
surface.

5)
Touch up abrasions and scratches
immediately to prevent the formation of
rust.
Maintenance of paintwork consists of
washing the car: the frequency
depends on the conditions and
environment where the car is used. For
example, it is advisable to wash the
vehicle more often in areas with high
levels of atmospheric pollution or salted
roads.
Some parts of the vehicle may be
covered with a matt paint which, in
order to be maintained intact, requires
special care: see the instructions in the
warning at the end of this paragraph
60)
To correctly wash the vehicle, follow
these instructions:
if the vehicle is washed remove the
aerial from the roof;
if high pressure jets or cleaners are
used to wash the vehicle, keep a
distance of at least 40 cm from the
