Caution!
If the LOW ENGINE OIL PRESSURE symbol switches on when driving, stop the engine immediately and contact an authorized dealer.
Warning LightWhat It Means What To Do
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 four minutes or until the engine is
allowed to cool whichever comes first.In normal driving conditions
: stop the vehicle, shut 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
offwith 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.

2. As soon as you cycle the ignition
switch to the ON position, you will see the
“Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb
check.
3. Approximately 15 seconds later, one
of two things will happen:
The MIL will flash for about ten
seconds and then return to being fully
illuminated until you turn OFF the ignition
or start the engine. This means that your
vehicle's OBD II system is not readyand
you should notproceed to the I/M
station.
The MIL will not flash at all and will
remain fully illuminated until you place
the ignition in the off position or start the
engine. This means that your vehicle's
OBD II system is readyand you can
proceed to the I/M station. If your OBD II system is
not ready,you
should see an authorized dealer or repair
facility. If your vehicle was recently
serviced or had a battery failure or
replacement, you may need to do nothing
more than drive your vehicle as you
normally would in order for your OBD II
system to update. A recheck with the
above test routine may then indicate that
the system is now ready.
Regardless of whether your vehicle's
OBD II system is ready or not, if the MIL is
illuminated during normal vehicle
operation you should have your vehicle
serviced before going to the I/M station.
The I/M station can fail your vehicle
because the MIL is on with the engine
running.

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 system operation, 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.
Drive Train Control (DTC) System
Some models of this vehicle are equipped
with an All-Wheel Drive system (AWD),
which offers an optimal drive for
countless driving conditions and road
surfaces. The system reduces tire
slipping to a minimum, automatically
redistributing the torque to the front and
rear wheels as needed.
To maximize fuel savings, the vehicle with
AWD automatically passes to rear-wheel
drive (RWD) when the road and
environmental conditions are such that
they wouldn't cause the tires to slip.
When the road and environmental
conditions require better traction, the
vehicle automatically switches to AWD
mode.
104
SAFETY

Note:
There may be a brief delay in shifting
to AWD mode after a tire slipping event
occurs.
If the system failure symbol switches
on, after starting the engine or while
driving, it means that the AWD system is
not working properly. If the warning
message activates frequently, it is
recommended to carry out the
maintenance operations.
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.
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 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.
