2019 Alfa Romeo Stelvio wheel torque

SYMBOLS ON THE DISPLAY
Red symbols
Symbol What it means
LOW ENGINE OIL PRESSURE
The symbol indicates that the engine oil pressure is low.
If it turns on temporarily or flashes (for about 5 seconds), check the oil level by following the corresponding procedure (see the
description in the “Checking levels” paragraph in the “Maintenance and care” chapter) and top up to the correct level if necessary.
If the symbol turns on continuously, contact an Alfa Romeo Dealership to have the system checked.
WARNING IF THE SYMBOL TURNS ON CONTINUOUSLY: Do not use the car until the failure has been solved. When the symbol
turns on, it does not indicate the amount of oil in the engine: the oil level can be checked on the display upon entering the vehicle
and also by activating the "Oil level" function on the Connect system.

ALTERNATOR FAILURE
The switching on of the symbol with engine on corresponds to an alternator failure.
Contact an Alfa Romeo Dealership as soon as possible.
POWER STEERING FAILURE
If the symbol remains on, you could not have steering assistance and the effort required to operate the steering wheel could be
increased; steering is, however, possible.
Contact an Alfa Romeo Dealership as soon as possible.
ALFA™ SYSTEM STEERING TORQUE (AST) FAILURE
The switching on of the symbol signals a failure in the automatic steering correction system.
Contact an Alfa Romeo Dealership to have the system checked.
IMPORTANT

KNOWING THE INSTRUMENT PANEL

ACTIVE SAFETYSYSTEMS
The vehicle may be equipped with the
following active safety devices:
ABS (Anti-Lock Brakes);
DTC (Drive Train Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
AST (Alfa™ Steering Torque);
HDC (Hill Discent Control)
For the operation of the systems, see the
following pages.
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 on a
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 ABS equipped on this vehicle is
provided with the "Brake by wire"
(Integrated Brake System - IBS) function.
With this system, the brake pedal
command given by pressing the brake
pedal is not transmitted hydraulically but
electronically, therefore, the light
pulsation that could be felt on the pedal
with the traditional system is no longer
perceptible.29) 30) 31) 32) 33) 34)
DTC (Drive Train Control)SYSTEM(where provided)
Some versions of this vehicle are
equipped with a four-wheel drive system
(AWD), activated on request, which offers
an optimal drive for countless driving
conditions and road surfaces. The system
reduces the slipping of the tyres to a
minimum, automatically redistributing
the torque to the front and rear wheels,
as needed.
To maximize fuel savings, the car with
AWD automatically passes to rear-wheel
drive (RWD) when the road and
environmental conditions are such that
they would not cause the tyres to slip.When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD mode.
35)
IMPORTANT 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.
36)
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 car’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 car to determine the trajectory
that the driver intends to follow and
compares it with the car’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 ESC
warning light on the instrument panel, to
inform the driver that the vehicle
stability and grip are critical.
37) 38) 39) 40) 41)
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 both 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.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.

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
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.
47) 48) 49)
HSA (Hill Start Assist)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 road
with 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.

AST (Alfa™ Steering Torque)SYSTEM
52)
The AST function integrates the ESC
system with the electric power steering
to increase the safety level of the whole
vehicle.
In critical situations (braking on surfaces
with different grip conditions), through
the AST function, the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes and
steering increases the sensation of
safety and control of the vehicle.
HDC (Hill Descent Control)SYSTEM(where provided)
On vehicles equipped in this way, this
function is an integral part of the ESC
system and is aimed at keeping the
vehicle at a constant speed during a
descent, operating autonomously and in
different ways on the brakes.
In this way the vehicle stability and
completely safe driving are guaranteed,
above all in poor grip conditions and
steep descents.The system has three different modes:
Off: the system is deactivated;
Enabled: the system is enabled and
ready to intervene when the activation
conditions are met;
Active: the system actively controls
the car speed.
Enabling the system
To enable the system, press the button
fig. 57.
The system is enabled if the car speed is
below 20 mph (30 km/h). The system
stays enabled until the car speed reaches
37 mph (60 km/h): the system is disabled
at faster speed.
System activation is indicated by the
white
icon on the display
fig. 58 turning on fixed.System activation
Once enabled, the HDC system will
activate automatically if the car is driven
downhill on a steep slope, higher than
8%.
The speed set for the HDC system can be
adjusted using the SET switch fig. 59 (in
the range from 1.25 mph - 15.5 mph to
6 km/h - 20 mph). Once the desired speed
has been reached, release the SET switch
and the HDC system will maintain the set
speed.
It is also possible to reduce the set speed
with the brake pedal. The system will
acquire the current speed when the pedal
is released as the reference.
