DYNAMIC STEERING TORQUE (DST)
S
YSTEM
DST uses the integration of the Electronic
Stability Control (ESC) system with the electric
power steering to increase the safety level of the
whole vehicle.
In critical situations (e.g. braking on surfaces with
different grip conditions), the ESC system
influences the steering through the DST function
to implement an additional torque contribution
on the steering wheel in order to suggest the
most correct maneuver to the driver.
The coordinated action of the brakes and
steering increases the safety and control of the
vehicle.

NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly depen -
dent on the driver’s sensitivity and overall reac -
tion to the applied torque. It is very important to
realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.
DRIVE TRAIN CONTROL (DTC) SYSTEM
Some models of this vehicle are equipped with an
All-Wheel Drive (AWD) system, 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.

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)
S
YSTEM
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 oversteer or
understeer.
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.

The PBA system is deactivated when the brake
pedal is released.
TRACTION CONTROL SYSTEM (TCS)
The TCS 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.
AUXILIARY DRIVING
SYSTEMS
The following auxiliary driving systems may be
available in this vehicle:
Blind Spot Monitoring (BSM) — if equipped
Active Blind Spot Assist (ABSA) — if equipped
Forward Collision Warning Plus (FCW+)
Tire Pressure Monitoring System (TPMS)
The vehicle may also be fitted with the following
driving assistance systems:
Driver Attention Assist (DAA)
Lane Departure Warning (LDW)
Lane Keeping Assist (LKA)
Highway Assist System (HAS)
Traffic Jam Assist (TJA)
Adaptive Cruise Control (ACC)
Intelligent Speed Control (ISC)
Traffic Sign Recognition (TSR)
For the operation of the DAA, LDW, LKA, HAS, TJA,
ACC, ISC, or TSR systems, see

Ú
page 81.

NOTE:
When driving on two-way roads where there is no
lane dividing center line (e.g. on unpaved roads),
the use of the ABSA, HAS, TJA, and LKA systems
is strongly discouraged as the system could
detect the entire road as single-lane dividing
lines.

NOTE:
The driving assistance systems are designed to
aid in driving the car. The driver must always
maintain a sufficient level of attention to the
traffic and road conditions and control the trajec -
tory of the car.
BLIND SPOT MONITORING (BSM)
S
YSTEM — IF EQUIPPED
The BSM system uses radar sensors, located in
the rear fascia/bumper, to detect the presence of
other vehicles in the rear side blind spots of your
vehicle.
Rear Sensor Location
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. PBA
cannot prevent collisions, including those
resulting from excessive speed in turns, driv -
ing on very slippery surfaces, or hydroplaning.
The capabilities of a PBA-equipped vehicle
must never be exploited in a reckless or dan -
gerous manner, which could jeopardize the
user's safety or the safety of others.

Sensors
The system uses radar sensors, located in the
rear fascia/bumper, to detect the presence of
vehicles (cars, trucks, motorbikes, etc.) in the
rear side blind spots of the car.
The sensors are activated when any forward gear
is engaged at a speed higher than about 6 mph
(10 km/h), or when REVERSE (R) is engaged.
The sensors are temporarily deactivated when
the car is stationary and in PARK (P).
The detection area of the system covers about a
lane on both sides of the car around 10 ft
(3 meters).This area begins from the door mirror and
extends for about 20 ft (6 meters) towards the
rear part of the car.
When the sensors are active the system monitors
the detection areas on both sides of the car and
warns the driver about the possible presence of
cars in these areas.
Rear Sensor Location
While driving, the system monitors the detection
zone in three different situations:
when you are being overtaken by a vehicle;
when you are overtaking a vehicle;
when a vehicle approaches from the side;
to check if it is necessary to intervene in order to
keep the vehicle inside the lane on both sides.

NOTE:
The system does not signal the presence of fixed
object (e.g. safety barriers, poles, walls, etc.).
However, in some circumstances, the system
may activate in the presence of these
objects.This is normal and does not indicate a
system malfunction. The system does not warn the driver about the
presence of cars coming from the opposite direc
-
tion, in the adjacent lanes.
Activation/Deactivation
The system can be activated/deactivated using
the “Driver Assistance” menu in the radio system.
Select signal type, strength levels and sensitivity.

NOTE:
Vehicles with an active system will display the
following screen, on the radio system.
ABSA Menu Screen
System Intervention
The system intervenes in the following
conditions:
the turn signals have been activated;
there is a vehicle in the adjacent lane on the
same side of the turn signal (blind spot area);
lane lines are not correctly detected;
the driver tries to change lanes intentionally.
Applying a torque that corrects the steering
wheel alignment does not always prevent an
accident. It is always the driver's responsi -
bility to steer, brake or accelerate, especially
after the ABSA system warning or after the
steering wheel torque intervention. The
driver is responsible for ensuring that there
are no pedestrians, other vehicles or objects
along the direction of the vehicle. Failure to
comply with these precautions may cause
serious accidents and injuries. The driver is
fully responsible for holding a safe distance
from the vehicle ahead respecting the
highway code in force in the respective
country.
In some cases, the system could apply an
improper torque to the steering wheel. This
application can be interrupted at any time by
turning the steering wheel in the opposite
direction.
WARNING!

When the front seat belts are fastened
The "Alfa DNA Pro" selector is not in RACE
position (if equipped)

NOTE:
If the seat belts of the front seats are not correctly
fastened, the system will not intervene on the
braking system (only audible and visual signals
will be provided).
Changing The System Sensitivity
The sensitivity of the system can be changed
through the Information and Entertainment
system menu, choosing from one of the following
three options: "Near", "Medium" or "Far". Refer to
the description in the Information and
Entertainment system Supplement for how to
change the settings.
The default setting is "Medium". With this setting,
the system warns the driver of a possible collision
with the vehicle in front when that vehicle is at a
standard distance, between that of the other two
settings.
With the system sensitivity set to "Far", the
system will warn the driver of a possible collision
with the vehicle in front when that vehicle is at a
greater distance, thus providing the possibility of
acting on the brakes more lightly and gradually.
This setting provides the driver with the maximum
possible reaction time to prevent a potential
collision.

NOTE:
The “Far” setting may result in a greater number
of FCW possible collision warnings experienced.
With the option set to "Near", the system will alert
the driver of a possible collision with the vehicle
in front when that vehicle is close. This setting
offers the driver a lower reaction time compared to the "Medium" and "Far" settings, in the event of
a potential collision, but permits more dynamic
driving of the vehicle.

NOTE:
The “Near” setting may result in a lesser number
of FCW possible collision warnings experienced.
The system sensitivity setting is kept in the
memory when the engine is turned off.
System Limited Operation Warning
If a dedicated message is displayed, a condition
limiting the system operation may have occurred.
The possible reasons of this limitation are
something is blocking the camera view or a fault.
If an obstruction is signaled, clean the area of the
radar on the front fascia/bumper, and the
camera area on the windshield.
If a fault in the system is occurring, it will still be
possible to drive the vehicle normally, but
automatic braking will not be available in the
event of an impending collision.
When the conditions limiting the system
functions end, this will go back to normal and
complete operation. Should the fault persist,
contact an authorized dealer.
System Failure Signaling
If the system turns off and a dedicated message
is shown on the display, it means that there is a
fault with the system.
In this case, it is still possible to drive the vehicle,
but you are advised to contact an authorized
dealer as soon as possible.
Radar Indication Not Available
If conditions are such that the radar cannot
detect obstacles correctly, the system is
deactivated and a dedicated message appears on the display. This generally occurs in the event
of poor visibility, such as when it is snowing or
raining heavily.
The function of this system can also be
temporarily reduced due to obstructions such as
mud, dirt or ice on the fascia/bumper. In such
cases, a dedicated message will be shown on the
display and the system will be deactivated. This
message can sometimes appear in conditions of
high reflectivity (e.g. tunnels with reflective tiles or
ice or snow). When the conditions limiting the
system functions end, it will go back to normal
and complete operation.
In certain cases, this dedicated message could
be displayed when the radar is not detecting any
vehicles or objects within its view range.
If atmospheric conditions are not the reason
behind this message, check if the sensor is dirty.
It could be necessary to clean or remove any
obstructions in the area.
If the message appears frequently, even in the
absence of atmospheric conditions such as snow,
rain, mud or other obstructions, contact an
authorized dealer for a sensor alignment check.
In the absence of visible obstructions, manually
removing the decorative cover trim and cleaning
the radar surface could be required. Have this
operation performed at an authorized dealer.

NOTE:
It is recommended that you do not install devices,
accessories or aerodynamic attachments in front
of the sensor or darken it in any way, as this can
compromise the correct functioning of the
system.

Frontal Collision Alarm With Active Braking — If
Equipped
If this function is selected, the brakes are
operated to reduce the speed of the vehicle in the
event of potential frontal impact.
This function applies an additional braking
pressure if the braking pressure applied by the
driver does not suffice to prevent potential frontal
impact.
The function is active with speed above 2 mph
(4 km/h).

NOTE:
When using an automatic car wash it is recom-
mended to deactivate the system through the
settings of the radio system. The system may
detect the presence of a car, a wall or another
obstacle and activate.
Driving In Special Conditions
In certain driving conditions, system intervention
might be unexpected or delayed. The driver must
therefore be very careful, keeping control of the
vehicle to drive in complete safety.
Driving close to a bend.
The vehicle ahead is leaving a roundabout.
Vehicles with small dimensions and/or not
aligned in the driving lane.
Lane change by other vehicles.
Vehicles traveling at right angles to the vehicle.

NOTE:

In particularly complex traffic conditions, the
driver can deactivate the system manually
through the Information and Entertainment
system.
If the driver presses the brake pedal fully or
makes an excessive steering maneuver during
system operation, the automatic braking
function may deactivate (e.g. to allow a
possible maneuver to avoid the obstacle).
The FCW system is automatically deactivated
when operating in race mode and a warning
message will be displayed on the instrument
cluster.
Driving Close To A Bend
When entering or leaving a wide bend, the system
may detect a vehicle in front of you, but not
driving in the same driving lane. In cases such as
these, the system may intervene.
Driving Around Wide Curves The Vehicle Ahead Is Leaving A Roundabout
On a roundabout, the system could intervene
when it detects a vehicle ahead that is leaving the
roundabout.
Driving In Roundabouts
Vehicles With Small Dimensions And/Or Not
Aligned In The Driving Lane
The system cannot detect vehicles in front of the
vehicle if they are outside the range of the radar
sensor and may not react to small vehicles, such
as bicycles or motorcycles.

compromised through the use of further
additives. Frequency of Oil Changes
In normal vehicle operating conditions, it is not
necessary to change the transmission oil.
REPLACING THE BATTERY
If necessary, replace the battery with another
battery with the same specifications. It is advised
to contact an authorized dealer for replacement.

NOTE:
Each time the 12 Volt battery is reconnected,
cycle the steering wheel all the way to the left.
Then cycle the steering wheel all the way to the
right to allow the steering angle sensor to learn
the steering angle thresholds.
Follow the battery manufacturer's instructions for
maintenance.

NOTE:
It will not be possible to open the liftgate with a
key or by pushing the button in the passenger compartment when the battery is disconnected.

FUSES
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
electrical circuit inside of the fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses
To avoid contamination from foreign matter
or moisture, use only new brake fluid or fluid
that has been in a tightly closed container.
Keep the master cylinder reservoir cap
secured at all times. Brake fluid in an open
container absorbs moisture from the air
resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or
prolonged braking, resulting in sudden brake
failure. This could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
