ENGINE TEMPERATURE WARNING LIGHT
This telltale warns of an overheated engine condition.
If the engine coolant temperature is too high, this
indicator will illuminate and a single chime will sound. If
the temperature reaches the upper limit, a continuous
chime will be sound for 4 minutes or until the engine is
allowed to cool whichever comes first.In normal driving conditions
: stop the vehicle, turn off the
engine and check that the coolant level in the reservoir is
not below the MIN mark. In this case, wait for the engine
to cool down, then slowly and carefully open the cap, top
up with coolant and check that the level is between the
MIN and MAX marks on the reservoir itself. Also check
visually for any fluid leaks. Contact an authorized dealer
if the telltale comes on when the engine is started again.
If the vehicle is used under demanding conditions (e.g. in
high-performance driving): slow down and, if the telltale
stays on, stop the vehicle. Stop for two or three minutes
with the engine running and slightly accelerated to
facilitate better coolant circulation, then turn the engine
off. Check that the coolant level is correct as described
above.

ONBOARD DIAGNOSTIC
SYSTEM
Operation
The OBD (Onboard Diagnostic system)
carries out a continuous diagnosis of the
components of the vehicle related to
emissions.
It also alerts the driver of when these
components are no longer in peak
condition by switching on the
warning
light on the instrument panel (see
“Warning Lights And Messages”
paragraph in this chapter).
The aim of the OBD system (Onboard
Diagnostic) is to:
Monitor the efficiency of the system
Indicate an increase in emissions
Indicate the need to replace damaged
components
The vehicle also has a connector, which
can interface with appropriate tools, that
makes it possible to read the error codes
stored in the electronic control units
together with a series of specific
parameters for engine operation and
diagnosis. This check can be carried out
by your authorized dealer.
Note: After eliminating a fault, to check
the system completely, your authorized
dealer is obliged to run tests and, if
necessary certain road tests.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an
Onboard Diagnostic system (OBD II) and
a connection port to allow access to
information related to the performance
of your emissions controls. Authorized
service technicians may need to access
this information to assist with the
diagnosis and service of your vehicle and
emissions system.
Warning!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access,
information stored in your vehicle systems,
including personal information.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal
requirement to pass an inspection of your
vehicle's emissions control system.
Failure to pass could prevent vehicle
registration.
For states that require
an Inspection and
Maintenance (I/M), this
check verifies the
“Malfunction Indicator
Light (MIL)” is functioning and is not on
when the engine is running, and that the
OBD II system is ready for testing.
Normally, the OBD II system will be ready.
The OBD II system may notbe ready if
your vehicle was recently serviced,
recently had a dead battery or a battery
replacement. If the OBD II system should
be determined not ready for the I/M test,
your vehicle may fail the test.
Your vehicle has a simple ignition
actuated test, which you can use prior to
going to the test station. To check if your
vehicle's OBD II system is ready, you
must do the following:
1. Cycle the ignition switch to the ON
position, but do not crank or start the
engine.
Note: If you crank or start the engine,
you will have to start this test over.

ACTIVE SAFETY SYSTEMS
The vehicle may be equipped with the
following active safety devices:
Anti-Lock Braking (ABS) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC)
System
Traction Control System (TCS)
Panic Brake Assist (PBA) System
Hill Start Assist (HSA) System
Dynamic Steering Torque (DST)
System
Active Torque Vectoring (ATV) System
For the operation of the systems, see the
following pages.
Anti-Lock Braking (ABS) System
An integral part of the braking system,
the ABS prevents one or more wheels
from locking and slipping in all road
surface conditions, regardless of the
intensity of the braking action. The
system ensures that the vehicle can be
controlled even during emergency
braking, allowing the driver to optimize
stopping distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions where 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, such as in a corner.
The Electronic Braking Force Distribution
(EBD) system works with the ABS,
allowing the brake force to be distributed
between the front and rear wheels.
System Intervention
The ABS equipped on this vehicle is
provided with the "Brake-by-wire"
(Integrated Brake System - IBS) function.
With this system, the command given
by pressing the brake pedal is not
transmitted hydraulically, but electrically.
Therefore, the light pulsation that is felt
on the pedal with the traditional system
is no longer noticeable.
Warning!
The ABS contains sophisticated electronic
equipment that may be susceptible to
interference caused by improperly installed
or high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead to
a collision. Pumping makes the stopping
distance longer. Just press firmly on your
brake pedal when you need to slow down or
stop.
The ABS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning.
The capabilities of an ABS equipped
vehicle must never be exploited in a reckless
or dangerous manner that could jeopardize
the user’s safety or the safety of others.
Electronic Stability Control (ESC)
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 appropriate
wheels. 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 path that
the driver intends to follow and
compares it with the vehicle’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.
90
SAFETY

Oversteeroccurs 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 ESC
warning light on the instrument panel,
to inform the driver that the vehicle
stability and grip are critical.
Warning!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESC
equipped vehicle must never be exploited in
a reckless or dangerous manner which could
jeopardize the user’s safety or the safety of
others.
Vehicle modifications, or failure to
properly maintain your vehicle, may change
the handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the steering
system, suspension, braking system, tire
type and size or wheel size may adversely
affect ESC performance. Improperly
inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle
modification or poor vehicle maintenance
that reduces the effectiveness of the ESC
system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
Traction Control System (TCS)
The system automatically operates in the
event of slipping, loss of grip on wet
roads (hydroplaning), and acceleration on
one or both drive wheels on roads that
are slippery, snowy, icy, etc. 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 Brake Limited
Differential (BLD) function is activated,
automatically braking the wheel which is
slipping (the behavior of a self-locking
differential is simulated). This will
increase the engine torque transferred to
the wheel which isn't slipping. System Intervention
The intervention of the system is
indicated by the flashing of the ESC
warning light on the instrument panel,
to inform the driver that the vehicle
stability and grip are critical.
Panic Brake Assist (PBA) 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
complements 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.
Warning!
The Panic Brake Assist (PBA) cannot prevent
the natural laws of physics from acting on
the vehicle, nor can it increase the traction
afforded by prevailing road conditions.
