engine Alfa Romeo Stelvio 2018 Service Manual

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.
105

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. 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.
Hill Start Assist (HSA) System
This is an integral part of the 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 (R). When starting from a 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!
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.
106
SAFETY

When the engine is started, the warning
light illuminates briefly to signal the
driver that the system is active.
Sensors
The sensors are activated when any
forward gear is engaged at a speed
higher than approximately 6 mph
(10 km/h) or when REVERSE is engaged.
The sensors are temporarily deactivated
when the vehicle is stationary or the
vehicle is in PARK (P).
The detection area of the system covers
approximately a lane on both sides of the
vehicle which is around 9 feet (3 m).
This area begins from the door mirror and
extends for approximately 19 feet (6 m)
toward the rear part of the vehicle.
When the sensors are active, the system
monitors the detection areas on both
sides of the vehicle and warns the driver
about the possible presence of vehicles
in these areas.While driving, the system monitors the
detection area from three different input
points (side, rear and front) to check
whether an alert needs to be sent to the
driver. The system can detect the
presence of a vehicle in one of these
three areas.
Note:
The system does not alert the driver
of the presence of fixed objects (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 alert the driver
about the presence of vehicles coming
from the opposite direction, in the
adjacent lanes.
Warning!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the
BSM system, always check your vehicle’s
mirrors, glance over your shoulder, and use
your turn signal before changing lanes.
Failure to do so can result in serious injury or
death.
Note:
For the system to operate properly,
the rear bumper area where the radar
sensors are located must stay free from
snow, ice and dirt gathered from the
road surface.
Do not cover the rear bumper area
where the radar sensors are located with
any object (e.g. adhesives, bike rack,
etc.).
If you wish to install a rear tow eye
after purchasing the vehicle, you will
need to deactivate the system via the
Information and Entertainment System.
To access the function, select the
following items in sequence on the main
menu:
1. “Settings.”
2. “Safety.”
3. “Blind Spot Alert.”
Rear View
The system detects vehicles coming from
the rear part of your vehicle on both sides
and entering the rear detection area with
a difference in speed of less than 31 mph
(50 km/h) in relation to your vehicle.0434132127USBSM Indicator Light

SAFETY

Overtaking Vehicles
If another vehicle is overtaken slowly,
with a difference in speed of less than
approximately 15 mph (25 km/h) and the
vehicle stays in the blind spot for
approximately 1.5 seconds, the warning
light on the door mirror of the
corresponding side illuminates.
If the difference in speed between the
two vehicles is greater than
approximately 15 mph (25 km/h), the
warning light does not illuminate.
Rear Cross Path Detection (RCP)
System
This system assists the driver during
reverse maneuvers in the case of reduced
visibility.
The RCP system monitors the rear
detection areas on both sides of the
vehicle to detect objects moving toward
the sides of the vehicle, with a minimum
speed between approximately 1 mph
(1 km/h) and 2 mph (3 km/h) and objects
moving at a maximum speed of 21 mph
(35 km/h), in areas such as parking lots.
The system activation is signaled to the
driver by an audible warning.
Note:If the sensors are covered by
objects or vehicles, the system may not
work as intended.
Warning!
Rear Cross Path Detection (RCP) is not a
back up aid system. It is intended to be used
to help a driver detect an oncoming vehicle in
a parking lot situation. Drivers must be
careful when backing up, even when using
RCP. Always check carefully behind your
vehicle, look behind you, and be sure to check
for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing
up. Failure to do so can result in serious
injury or death.
Operating Mode
The system may be activated/
deactivated via the Information and
Entertainment System. To access the
function, select the following items on
the main menu in sequence:
1. “Settings.”
2. “Safety.”
3. “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,
thus indicating the intention to change
lane. 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 neither an acoustic
nor 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 last set will
be recalled and used.

where the driver does not brake at all or
not sufficiently in the event of a potential
frontal impact.
Disable: the system does not provide
visual and audible warnings, limited
braking, automatic braking or additional
assistance in braking stage. The system
will therefore provide no indication of a
possible collision.
Activation/Deactivation
The Forward Collision Warning system is
activated whenever the engine is started
regardless of what is shown in the
Information and Entertainment System.
Following a deactivation, the system will
not warn the driver about the possible
collision with a preceding vehicle,
regardless of the setting selected in the
Information and Entertainment System.
Note: Each time the engine is started,
the system is activated regardless of
what setting was selected when the
engine was turned OFF.
This function is not active at a speed
lower than 4 mph (7 km/h) or higher than
124 mph (200 km/h).
The system is active:
Each time the engine is started.
When feature is selected within the
Information and Entertainment System.
When the ignition is in the ON position.
When the vehicle speed is between
4 mph (7 km/h) and 124 mph (200 km/h).
When the front seat belts are
fastened.
The "Alfa DNA Pro" selector is not in
RACE position (if equipped).
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", "Med" or "Far". Refer to the
description in the Information and
Entertainment System Supplement for
how to change the settings.
The default setting is "Med". 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 drivers with the
maximum possible reaction time to
prevent a potential accident.
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 "Med" and "Far" settings, in the event of a
potential collision, but permits more
dynamic driving of the vehicle.
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 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 your 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
your authorized dealer as soon as
possible.

Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC
position, the air bag system is not on and
the air bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag
system even if the battery loses power or
it becomes disconnected prior to
deployment.
The ORC turns on the Air Bag Warning
Light in the instrument panel for
approximately four to eight seconds for a
self-check when the ignition switch is
first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will
turn off. If the ORC detects a malfunction
in any part of the system, it turns on the
Air Bag Warning Light, either
momentarily or continuously. A single
chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that
will illuminate the instrument panel Air
Bag Warning Light if a malfunction is
detected that could affect the air bag
system. The diagnostics also record the
nature of the malfunction. While the air
bag system is designed to be
maintenance free, if any of the followingoccurs, have an authorized dealer service
the air bag system immediately.
The Air Bag Warning Light does not
come on during the four to eight seconds
when the ignition switch is first in the
ON/RUN position.
The Air Bag Warning Light remains on
after the four to eight-second interval.
The Air Bag Warning Light comes on
intermittently or remains on while
driving.
Note: If the speedometer, tachometer,
or any engine related gauges are not
working, the Occupant Restraint
Controller (ORC) may also be disabled. In
this condition the air bags may not be
ready to inflate for your protection. Have
an authorized dealer service the air bag
system immediately.
Warning!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if
it comes on as you drive, have an authorized
dealer service the air bag system
immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The
Redundant Air Bag Warning Light will
stay on until the fault is cleared. In
addition, a single chime will sound to alert
you that the Redundant Air Bag Warning
Light has come on and a fault has been
detected. If the Redundant Air Bag
Warning Light comes on intermittently or
remains on while driving have an
authorized dealer service the vehicle
immediately. For additional information
regarding the Redundant Air Bag Warning
Light refer to “Getting To Know Your
Instrument Panel” section of this manual.
Front Air Bags
This vehicle has front air bags and
lap/shoulder belts for both the driver and
front passenger. The front air bags are a
supplement to the seat belt restraint
systems. The driver front air bag is
mounted in the center of the steering
wheel. The passenger front air bag is
mounted in the instrument panel, above
the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on
the air bag covers.
123

Warning!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as
well.
Note:
Air bag covers may not be obvious in
the interior trim, but they will open
during air bag deployment.
After any collision, the vehicle should
be taken to an authorized dealer
immediately.
Enhanced Accident Response
System
In the event of an impact, if the
communication network remains intact,

4. Remove slack in the tether strap
according to the child restraint
manufacturer’s instructions.
Transporting Pets
Air Bags deploying in the front seat could
harm your pet. An unrestrained pet will be
thrown about and possibly injured, or
injure a passenger during panic braking or
in a collision.
Pets should be restrained in the rear seat
in pet harnesses or pet carriers that are
secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN
THE CARGO AREA.
Warning!
Do not leave children or animals inside
parked vehicles in hot weather. Interior heat
build-up may cause serious injury or death.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle. In
a collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
Warning!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage
or in confined areas any longer than needed
to move your vehicle in or out of the area.
141

If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the climate
control BLOWER switch is set at high speed.
DO NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your heating
or cooling controls to force outside air into
the vehicle. Set the blower at high speed.
The best protection against carbon
monoxide entry into the vehicle body is a
properly maintained engine exhaust
system.
Whenever a change is noticed in the
sound of the exhaust system, when
exhaust fumes can be detected inside the
vehicle, or when the underside or rear of
the vehicle is damaged, have a competent
mechanic inspect the complete exhaust
system and adjacent body areas for
broken, damaged, deteriorated, or
mispositioned parts. Open seams or
loose connections could permit exhaust
fumes to seep into the passenger
compartment. In addition, inspect the
exhaust system each time the vehicle is
raised for lubrication or oil change.
Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced
immediately. Do not disassemble or
modify the system.
Front seat belt assemblies must be
replaced after a collision. Rear seat belt
assemblies must be replaced after a
collision if they have been damaged (i.e.,
bent retractor, torn webbing, etc.). If
there is any question regarding seat belt
or retractor condition, replace the seat
belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on
for four to eight seconds as a bulb check
when the ignition switch is first turned to
ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at
your authorized dealer as soon as
possible. After the bulb check, this light
will illuminate with a single chime when a
fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on
intermittently or remains on while
driving, have your authorized dealer
service the vehicle immediately. Refer to
“Occupant Restraint Systems” in “Safety”
for further information.
Defroster
Check operation by selecting the defrost
mode and place the blower control on
high speed. You should be able to feel the
air directed against the windshield. See
your authorized dealer for service if your
defroster is inoperable.
