2021 ALFA ROMEO STELVIO wheel torque

STARTING AND OPERATING

128

The system operates in the same way, but
mirrored, in the event of exiting the right lane
when only the right lane marking has been
detected.
Left Lane Departure — Both Lanes Detected
When the system is active, both lane lines on
the display illuminate in white to indicate that
both of the lane markings have been detected.
When lane markings are detected, the system
is ready to provide indications in case the
driver unintentionally leaves the lane (turn
signal not activated).
As the Lane Departure Warning system
detects the lane markings while the vehicle is
in motion, it will adjust the display accordingly
(from white to yellow and yellow to white, and
increase their thickness).
If a lane line is crossed, the driver is alerted by
an audible signal as well as the visual indica-
tion in the instrument cluster. The signal is
emitted through the speakers on the side of
the lane limit which is being crossed (e.g. if the
vehicle is exceeding the left line of the lane,
the audible signal will come from the speakers
on the left of the vehicle).
Limited Operation Warning
If a message appears on the display, a condi -
tion limiting the Lane Departure Warning
system operation may have occurred. This
could be an obstruction of the camera view, or
a fault in the system.
If an obstruction is detected, clean the area of
the windshield by the interior rearview mirror. Although the vehicle can still be driven in
normal conditions, the system may not func
-
tion properly.
When the conditions limiting the system are
corrected, it will go back to normal operation.
Should a fault persist, contact an authorized
dealer.
System Failure Warning
If the system turns off and appears on the
display, it means that there is a system fault.
In this case, it is still possible to drive the
vehicle, but you are advised to contact an
authorized dealer as soon as possible.
Changing Lane Departure Warning Status
The system's sensitivity can be set through the
radio system. Sensitivity “High” or “Low” can
be selected.
To access the function, from the main menu
select the following in order:
1. “Settings”
2. “Driver Assistance”
3. “Lane Departure Warning”
4. “Sensitivity”
LANE KEEPING ASSIST (LKA)
SYSTEM —IF EQUIPPED
The Lane Keeping Assist (LKA) system uses a
camera located on the windshield to detect
the lane markings and calculate the position of the vehicle within such markings, in order to
make sure that the vehicle remains inside the
lane. This is an active system that will apply
torque to the steering wheel if it senses that
the vehicle is drifting out of the lane.
When one or both lane markings are detected
and the vehicle passes over one without a turn
signal being applied, the system will apply
torque to the steering wheel and a visual
signal will be displayed in the instrument
cluster display. An audible signal may also
sound.
If the vehicle continues to go beyond the lane
line without any driver intervention, the
surpassed lane line (left or right) will light up
on the instrument cluster display to urge the
driver to bring the vehicle back inside the lane
markings.

Traffic And Road Conditions
High fuel consumption is caused by heavy
traffic, for instance when traveling in traffic
with frequent use of low gears or in cities with
many traffic lights. Winding mountain roads
and rough road surfaces also adversely affect
consumption.
Stops In Traffic
During prolonged stops (e.g. railway cross-
ings), turn off the engine.
Performance — Quadrifoglio
This vehicle is equipped with an engine
capable of delivering exceptionally fast accel -
eration and speed:
Peak power: 505 HP at 6,500 RPM.

Peak torque: 443 ft-lbs at 2,500–5,000 RPM.

Top speed: 176 mph (283 km/h).

Acceleration from 0 to 60 mph (0 to 100 km/h):
3.6 seconds.

For safe driving, it is essential, particularly
during the first days of use, to get to know the
car by driving carefully and gradually discov -
ering its performance.
Brakes
The car braking system may be available with
four carbon-ceramic material brake discs, one
on each wheel. In order to guarantee the maximum braking
capacity for the first use, Alfa Romeo performs
a "run-in" procedure for discs and pads directly
at the factory.
The use of carbon-ceramic material brake
discs guarantees braking features (better
deceleration/pedal load ratio, braking
distances, fading resistance) proportional to
the dynamic features of the car in addition to
considerably decreasing the unsprung compo
-
nent weight.
The materials used and the structural features
of the system could generate unusual noises
which have absolutely no adverse effect on
correct operation and reliability of the braking
system.
Greater pressure may need to be applied to
the brake pedal the first time to keep the same
braking capacities in presence of condensa -
tion or salt on the braking surfaces, for
example after washing or if the car is not used
for a long time.

NOTE:

Given the high technological level of this
system, any servicing on it must be performed
by an authorized dealer which exclusively has
the skills needed for the repair and mainte -
nance operations. In case of intensive, high-performance use of
the car, have the efficiency of the
carbon-ceramic material braking system
inspected as shown on the Maintenance Plan
at an authorized dealer.
Driving On Race Tracks
Before driving on a track using a racing style, it
is necessary to:
Attend a race track driving course.
Check the liquid levels in the engine
compartment
Ú

page 208.
Have the car inspected at an authorized
dealer.
Remember that the car was not designed to be
driven exclusively on the race track and that
this use increases stress and component
wear.

NOTE:

Quadrifoglio front brakes are equipped with
Non-Asbestos Organic (NAO) type pads. These
pads are NOT suitable for high thermal loads
(for example track use). If you want to use
vehicle on a track it is recommended to use
the optional CCM Brakes (Carbon Ceramic
Brake disc).

SAFETY
This very important section describes the
safety systems that your vehicle may be
equipped with, and provides instructions on
how to use them correctly.
ACTIVE SAFETY SYSTEMS
The vehicle may be equipped with the
following active safety devices:
Anti-Lock Brake System (ABS)
Active Torque Vectoring (ATV) System
Dynamic Steering Torque (DST) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC) System
Hill Descent Control (HDC) System
Hill Start Assist (HSA) System
Panic Brake Assist (PBA) System
Traction Control System (TCS)
For system operation, see the following pages.
Anti-Lock Brake System (ABS)
An integral part of the braking system, the ABS
prevents one or more wheels from locking and
slipping in all road surface conditions, regard -
less 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 emer
-
gency 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.Active Torque Vectoring (ATV) System — If
Equipped
The dynamic drive control is used to optimize
and balance the drive torque between the
wheels of the same axles. The ATV system
improves the grip in turns, sending more drive
torque to the external wheel.
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 capa -
bility. Installation of such equipment
should be performed by qualified profes -
sionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead
to a collision. Pumping makes the stop -
ping 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 effi -
ciency beyond that afforded by the condi -
tion 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 reck -
less or dangerous manner that could jeop -
ardize the user’s safety or the safety of
others.

SAFETY

146

Given that, in a turn, the external wheels of the
car travel more than the internal ones and
therefore turn faster, sending a higher thrust
to the external rear wheel allows for the car to
be more stable and to not suffer an "under-
steer" condition. Understeer occurs when the
vehicle is turning less than appropriate for the
steering wheel position.
Dynamic Steering Torque (DST) System
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 func -
tion to implement an additional torque contri -
bution 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 dependent on the driver’s
sensitivity and overall reaction 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 condi
-
tions 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 environ -
mental 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) System
The ESC system improves the directional
control and stability of the vehicle in various
driving conditions.
The ESC system corrects the vehicle’s under -
steer 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.

HDC Speed SET Switch
Once the desired speed has been reached,
release the SET switch and the HDC system
will maintain the set speed. After set speed is
established, the HDC system will automatically
brake to keep the vehicle at the set speed if
the accelerator pedal is released and the
vehicle gets close to the set speed.
It is possible to reduce the set speed with the
brake pedal. When the pedal is released, the
system will adjust the set speed to the new
current speed.

NOTE:
If the vehicle’s speed exceeds 6 mph (10 km/h),
but remains below 37 mph (60 km/h) and the
accelerator pedal is released, as soon as the
vehicle gets close to the set speed the HDC
system will automatically brake to keep the
vehicle at the set speed.

The driver can cancel HDC system intervention
at any time by pressing the accelerator pedal. System Deactivation
The HDC system will be deactivated, but
remain available, if any of the following condi
-
tions are met:
The vehicle is traveling on a downhill slope
with a gradient less than 8%, on a level
surface, or on an uphill grade.
PARK (P) mode is engaged.
Disabling The System
The system is disabled if any of the following
conditions are met:
The HDC switch is pressed.
Cruise Control/Adaptive Cruise Control is
activated.
A vehicle speed of 37 mph (60 km/h) is
exceeded.
System deactivation is shown by the icon
on the display turning off.
Hill Start Assist (HSA) System
HSA is an integral part of the Electronic
Stability Control (ESC) system that facilitates
starting on slopes, activating automatically in
the following cases:
Uphill: the vehicle is stationary on a road
with a gradient higher than 5%, the engine
is running, the brake is pressed, and the
transmission is in NEUTRAL (N) or a gear
other than REVERSE (R) is engaged.
Downhill: the vehicle is stationary on a road
with a gradient higher than 5%, the engine
is running, the brake is pressed, and the
transmission is in REVERSE.
When starting to move forward from a
complete stop, 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
two seconds, allowing your right foot to be
moved easily from the brake pedal to the
accelerator.
The system will automatically deactivate after
two seconds without starting, 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 vehicle.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to
the driving conditions and is responsible for
maintaining a safe vehicle speed.

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 thesystem. 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.Traction Control System (TCS)
The TCS automatically operates in the event of
slipping, loss of grip on wet roads (hydro
-
planing), 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 are
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)
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight
rolling may occur, such as on minor hills or
with a loaded vehicle, or while pulling a
trailer. HSA is not a substitute for active
driving involvement. It is always the driver’s
responsibility to be attentive to distance to
other vehicles, people, and objects, and
most importantly brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is
always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision or
serious personal injury.
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, driving on very slippery
surfaces, or hydroplaning. The capabilities
of a PBA-equipped vehicle must never be
exploited in a reckless or dangerous
manner, which could jeopardize the user's
safety or the safety of others.

Operating Mode
The system may be activated/deactivated via
the radio system. To access the function,
select the following items on the main menu in
sequence:
1. “Driving Assistance”
2. “Blind Spot Alert”
“Blind Spot Alert”, “Visual” Mode
When the system is enabled, the warning light
within the door mirror on the side of the
detected object illuminates.
The visual warning on the mirror will blink if the
driver activates the turn signals, indicating a
lane change.
The warning light will be constant if the driver
stays in the same lane.
“Blind Spot Alert” Function Deactivation
When the system is deactivated (“Blind Spot
Alert” mode off), the BSM or RCP systems will
not emit an audible or a visual warning.
The BSM system will store the operating mode
that was active when the engine was stopped.
Each time the engine is started, the operating
mode stored previously will be recalled and
used
Ú
page 268.
Active Blind Spot Assist (ABSA) System — If
Equipped
The ABSA system is to help avoid/limit lateral
collisions with cars coming from adjacent lanes changing the vehicle’s trajectory in order
to try to keep it in the detected lane.
The system warns the driver about the pres
-
ence of other vehicles in the detection area by
illuminating the warning light located within
the door mirror on the side in which the other
vehicle was detected and by means of an
acoustic signal and/or vibration on the
steering wheel and/or counter-steering torque
on the steering wheel (if the respective item on
the “Driver Assistance” menu is set up and
then “Safety” is selected on the radio system).
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active (the warning light comes on
even if the system is activated through the
radio system menu).
ABSA Indicator Light 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.
WARNING!
The accident risk persists despite the
application of torque to the steering wheel
by the ABSA system.
Applying a torque that corrects the
steering wheel alignment does not always
prevent an accident. It is always the
driver's responsibility to steer, brake or
accelerate, especially after the ABSA
system warning or after the steering wheel
torque intervention. The driver is respon
-
sible for ensuring that there are no pedes -
trians, 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 turning the steering wheel in the
opposite direction.
21_GU_OM_EN_USC_t.book Page 152

153

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 moni-
tors 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 detec
-
tion 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
direction, 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. System intervention
The system intervenes in the following condi
-
tions:
the direction indicators have been turned
on;
there is a vehicle in the adjacent lane on the
same side of the direction indicator (blind
spot area);
lane lines are not correctly detected;
the driver tries to change lanes intention -
ally.
If the system detects the presence of a vehicle
in the rear side blind spots of the car, it applies
a torque on the steering wheel (if it has been
set through the “Settings” menu of the radio
system), in order to warn the driver of the need
to keep the car inside the lane and thus avoid
collisions with other vehicles.
The application of torque and vibration is
however only available with car speed
between 37 mph (60 km/h) and 110 mph
(180 km/h).
