engine Alfa Romeo Stelvio 2018 Repair Manual

Caution!
Before moving the transmission gear
selector out of PARK, you must push the
ignition button to cycle from STOP/OFF
mode to the ON mode, and also press the
brake pedal. Otherwise, damage to the gear
selector could result.
DO NOT race the engine when shifting
from PARK or NEUTRAL into another gear
range, as this can damage the drivetrain.
REVERSE (R)
Select this mode only with the vehicle at
a standstill.
NEUTRAL (N)
Use this range when the vehicle is
standing for prolonged periods with the
engine running. The engine may be
started in this range. Apply the electric
park brake and shift the transmission
into PARK (P) if you must leave the
vehicle.
Warning!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You
might lose control of the vehicle and have a
collision.
DRIVE (D)
Use this mode in normal driving
conditions.
Shifting from DRIVE (D) to PARK (P) or
REVERSE (R) modes must take place
only after releasing the accelerator
pedal, with vehicle at a standstill and
brake pedal pressed.
This mode ensures automatic
engagement of the most suitable gears
for driving needs and maximum fuel
economy in terms of consumption.
In this position, the transmission shifts
the gears automatically, selecting the
most suitable for forward driving among
those available as you go. In this way the
vehicle's optimal driving characteristics
are provided for all conditions.
AutoStick
In the case of frequent shifting (e.g. for
sport driving, when the vehicle is driven
with a heavy load, on slopes, when towing
heavy trailers), it is recommended to use
the AutoStick (sequential shifting) mode
to select and keep a lower fixed ratio.
In these conditions, the use of a lower
gear improves vehicle performance and
prevents overheating.
It is possible to shift from DRIVE (D)
mode to AutoStick mode regardless of
vehicle speed. Activation
Starting from DRIVE (D) mode, to
activate the sequential drive mode, move
the gear selector to the left (– and +
indication of the trim). The gear engaged
will be shown on the display.
Shifting is made by moving the gear
selector forward, toward symbol – or
backward, toward symbol +.
Steering Column Mounted Shift
Paddles
The gear can be manually shifted also by
using the paddles behind the steering
wheel, pull the right paddle (+) toward the
steering wheel and release it to engage a
higher gear, perform the same operation
with the left paddle (-) to engage a lower
gear.
Note:
If only one manual shift is
necessary, the letter (D) will remain on
the display with the engaged gear next to
it.

Deactivation
To deactivate the sequential driving
mode, bring the gear selector back in
position DRIVE (D) ("automatic" driving
mode).
Warning!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the vehicle
could skid, causing a collision or personal
injury.
Note:
To select the correct gear for
maximum deceleration (engine brake),
just keep the gear paddle pulled (–): the
transmission goes to an operating mode
in which the vehicle can slow down
easily.
The vehicle will keep the gear
selected by the driver until the safety
conditions allow it.
This means, for example, that the
system will try to prevent the engine
from switching off, automatically
downshifting if the engine speed is too
low.
Automatic Transmission Limp Home
Mode
Transmission function is monitored
electronically for abnormal conditions. If
a condition is detected that could result
in transmission damage, Transmission
Limp Home Mode is activated.
In this condition, the transmission stays
in fourth gear, regardless of the selected
gear. Positions PARK (P), REVERSE (R)
and NEUTRAL (N) still work.
The
symbol might light up in the
instrument cluster.
Temporary failure
In the event of a momentary problem, the
transmission can be reset to regain all
forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK (P),
if possible. If not, shift the transmission
to NEUTRAL (N).
3. Push and hold the ignition until the
engine turns OFF.
4. Wait for about 10 seconds, then
restart the engine.
5. Shift into the desired gear range. If
the problem is no longer detected, the
transmission will return to normal
operation.
Note: Even if the transmission can be
reset, we recommend that you visit your authorized dealer at your earliest
possible convenience. Your authorized
dealer has diagnostic equipment to
determine if the problem could reoccur. If
the transmission cannot be reset, service
is required at your authorized dealer.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake
Transmission Shift Interlock system
(BTSI) that holds the gear selector in
PARK (P) unless the brakes are applied.
This system prevents you from moving
the gear selector from position PARK (P)
unless the brakes are applied.
To shift the transmission out of PARK (P),
the ignition must be cycled to the ON
position (engine running or not) and the
brake pedal must be pressed.
Brake/Transmission Shift Interlock
Disabling
Only if strictly necessary (e.g. pushing the
vehicle, conveyor vehicle washing
systems), inhibit the automatic activation
of PARK (P) mode when stopping the
engine. To do so, follow the directions
below:
1. Bring the vehicle to a standstill.
2. Place the transmission in the
NEUTRAL (N) position.
3. Push the ignition button for at least
three seconds.
156
STARTING AND OPERATING

The automatic activation of PARK (P)
when the engine is stopped can also be
deactivated on the Information and
Entertainment system by selecting the
following functions on the main menu:
"Settings", "Driver Assistance" and
"Automatic Parking Brake".
Important Notes
Failure to comply with what is reported
below may damage the transmission:
Shift into PARK (P) mode only with the
vehicle at a standstill.
Select REVERSE (R) mode, or pass
from REVERSE to another mode only
with the vehicle at a standstill and engine
idling.
Do not change between PARK (P),
REVERSE (R), NEUTRAL (N) or DRIVE (D)
modes with engine running at a speed
above idling.
Before activating any transmission
operating mode, fully depress the brake
pedal.
Note: The unexpected movement of the
vehicle can injure the occupants or
people nearby. Do not leave the vehicle
with engine running: before getting out of
the passenger compartment always
engage the electric park brake, select the
PARK (P) mode, stop the engine.
Warning!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could
accelerate quickly forward or in reverse.
You could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always apply the park brake, shift
the transmission into PARK, and turn the
ignition STOP/OFF. When the ignition is in
the STOP/OFF mode, the transmission is
locked in PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always make
sure the ignition is in the STOP/OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allowing
children to be in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously or fatally
injured. Children should be warned not to
touch the parking brake, brake pedal or the
transmission gear selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition in the
AVV or ON mode. A child could operate
power windows, other controls, or move the
vehicle.
Caution!
Only engage the gear with engine at idling
while fully depressing the brake pedal. If the
transmission temperature exceeds the
normal operating limits, the transmission
control unit may change the gear
engagement order and reduce the drive
torque. If the transmission overheats, it
could operate incorrectly until it cools down.
When using the vehicle with extremely
low external temperatures, the
transmission operation may change
depending on the engine and transmission
temperature, as well as vehicle speed.
Activation of the torque converter clutch
and of the eighth gear is inhibited until the
transmission oil is correctly warmed up.
Complete operation of the transmission will
be enabled as soon as the fluid temperature
reaches the predefined value.

ALFA DNA PRO SELECTOR
Alfa DNA Pro System
This vehicle is equipped with a Alfa DNA
Pro system selector (located on the
center console). There are four modes of
operation to be selected according to
driving style and road conditions:
d = Dynamic (sports driving mode).
n = Natural (mode for driving in normal
conditions).
a = Advanced Efficiency (ECO driving
mode for maximum fuel savings).
RACE = track race driving mode.
= Adjusts the calibration of the
active suspension.
Unlike the other modes, the RACE
position does not latch; therefore, by
rotating the selector to RACE, it will
return to its initial position "d". On the instrument panel display, the
different modes are characterized by
different colors:
Natural - Blue
Dynamic - Red
Advanced Efficiency - Green
RACE - Yellow
Each driving mode is graphically different
in frame color and contents of each
individual "performance" screen.
Driving Modes
"Natural" Mode
“Natural” Mode is characterized by
reduced engine performance and ECO
shifting strategy for the automatic

STARTING AND OPERATING

ALFA ACTIVE SUSPENSION
(AAS)
The vehicle's electronic suspension
management system is aimed at
optimizing the vehicle's performance.
The system continuously monitors the
damping of the suspensions through the
actuator installed on each shock
absorber. This way, the calibration of the
shock absorbers can be adjusted to the
conditions of the road surface and to the
dynamic conditions of the vehicle,
improving its comfort and road holding.
The driver can choose, even while driving,
(only in "Dynamic” mode), between two
types of suspension calibration: a more
sporty or a more comfortable one.
By pushing the button, the system
changes the shock absorber calibration.
In case of a system failure, the symbol
and a dedicated message will be
shown on the instrument panel display.
STOP/START SYSTEM
The Stop/Start system automatically
shuts off the engine during a vehicle stop
if the required conditions are met.
Releasing the brake pedal or accelerator
pedal will automatically restart the
engine.
The function was developed to increase
vehicle efficiency by reducing fuel
consumption, gas emissions, and sound
pollution.
Note:When the Stop/Start system
stops the engine, the power steering is
also disabled.
Operating Mode
Stopping The Engine
With the vehicle at a standstill and brake
pedal pressed, the engine switches off if
the gear selector is in a position other
than REVERSE (R).
The system does not operate when the
gear selector is in REVERSE (R), in order
to make parking maneuvers easier.
In the event of stops uphill, engine
switching off is disabled to make the "Hill
Start Assist" function available (works
only with running engine).
Note: The engine can only be
automatically stopped after having run at
about 6 mph (10 km/h). After an
automatic restart, the vehicle only needs
to exceed a speed of 0.3 mph (0.5 km/h)
to stop the engine. Engine stopping is signaled by the
symbol lighting up on the instrument
cluster display.
Restarting The Engine
To restart the engine, release the brake
pedal.
With the brake pressed and the
transmission in automatic mode DRIVE
(D), the engine will restart by shifting to
REVERSE (R), to PARK (P) or to
"AutoStick".
With brake pressed if the gear selector is
in "AutoStick" mode, the engine will
restart by shifting to PARK (P) or by
moving the selector to + or -.

System Activation
The activation of the system is indicated
by the
symbol lighting up on the
display. In this condition, the light on the
button is off.
System Deactivation
A message will appear on the display
when the system is deactivated. In this
condition, the light on the button is on.
Note: Each time the engine is started,
the system is activated regardless of
where was when it was previously
switched off.
Possible Reasons The Engine Does Not
Autostop
For higher comfort and increased safety,
and to reduce emissions, there are
certain conditions where the engine will
not autostop despite the system being
active, such as:
Engine still cold.
Especially cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
Reverse gear engaged (e.g. for parking
maneuvers).
With the automatic climate control
active, an adequate cabin heating or
cooling comfort has not been reached or
with MAX-DEF function active.
During the first period of use, to
initialize the system.
Steering angle beyond threshold.
Engine Restarting Conditions
Due to comfort, emission control, and
safety reasons, the engine can restart
automatically without any action by the
driver, under special conditions, such as:
Battery not sufficiently charged.
Reduced braking system vacuum (e.g.
if the brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on
roads with a grade).
Engine stopping by the Stop/Start
system for more than approx. three
minutes.
With the automatic climate control
active, an adjustment in cabin heating or
cooling is made or with MAX-DEF
function active.
Safety Functions
When the engine is stopped through the
Stop/Start system, if the driver releases
their seat belt, opens the driver's or
passenger's door, or opens the hood from
inside the vehicle, the engine can be
restarted only by using the ignition.
This condition is indicated to the driver
both through a buzzer and a message on
the instrument cluster display.
Energy Saving Function
If the driver does not carry out any action
for more than three minutes after the
automatic engine restart, the Start/Stop
system will switch off the engine in order
to prevent fuel consumption.
In this situation, the engine can only be
restarted using the ignition device.
Note: It is possible to keep the engine
running by deactivating the system.
Irregular Operation
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, refer to "Warning
Lights and Messages" paragraph in
"Getting To Know Your Instrument Panel".
Vehicle Inactivity
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of the
battery power supply.
Proceed as follows:
Remove connector from socket to
disconnect sensor (battery status
monitoring) installed on the negative pole
of the battery. This sensor should never
be disconnected from the pole except if
the battery is replaced.
162
STARTING AND OPERATING

Setting a speed activates the system.
The display shows the icon in green with
the set speed.
Note:The system cannot be enabled
when RACE mode is active.
Warning!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it
to go faster than you want. You could lose
control and have a collision. Always leave
the system off when you are not using it.
Pausing / Deactivating
With the system enabled (speed not set),
push the
(on/off) button to disable.
With the system active (speed set), push
the
(on/off) button to pause. The
display will show the icon in white with
the speed in brackets. To then deactivate
the system, push the
(on/off) button
again.
Setting The Desired Speed
The speed can be set from a minimum of
20 mph (30 km/h) to a maximum of
110 mph (180 km/h).
When the vehicle reaches the desired
speed, push the SET switch upward or
downward and release it to activate the
system. When the accelerator is released,
the vehicle will maintain the set speed
automatically. While the accelerator pedal is pressed,
the system will not be able to control the
distance between the vehicle and the one
ahead. In this case, the speed will be
determined only by the position of the
accelerator pedal.
The system will return to normal
operation as soon as the accelerator
pedal is released.
The system
cannotbe set:
When pressing the brake pedal.
When the brakes are overheated.
When the electric park brake has been
operated.
When either PARK (P), REVERSE (R) or
NEUTRAL (N) is engaged.
When the engine rpm is above a
maximum threshold.
When the vehicle speed is not within
the operational speed range.
When the ESC (or ABS or other
stability control systems) are operating
or have just operated.
When the ESC system is off.
When the Forward Collision Warning
system (if equipped) is braking
automatically.
In the event of system failure.
When the engine is OFF.
In case of obstruction of the radar
sensor (in this case the bumper area
where it is located must be cleaned).
If the system is set, the conditions
described above also cause a
cancellation or deactivation of the
system. These situations may vary
according to the conditions.
Note: The system will not be deactivated
when speeds higher than those set are
reached by pressing the accelerator
pedal above 110 mph (180 km/h). In
these situations, the system may not
work correctly and it is recommended to
deactivate it.
To Vary The Speed Setting
Increasing Speed
Once the system has been activated, you
can increase the speed by lifting the SET
switch. Each time it is operated, the
speed increases by 1 mph.
By holding the button up, the set speed
will increase in increments of 5 mph until
0403132201USSET Switch
168
STARTING AND OPERATING

the button is released. Then, the new
speed will be set.
Decreasing Speed
Once the system has been activated, you
can decrease the speed by lowering the
SET switch. Each time it is operated, the
speed decreases by 1 mph.
By holding the button down, the set
speed will decrease in increments of
5 mph until the button is released. Then,
the new speed will be set.
Note:
Moving the SET switch allows you to
adjust the speed according to the
selected unit of measurement ("US" or
"metric") set on the Information and
Entertainment System (see dedicated
supplement).
When the unit of measurement is set
to metric, holding the SET switch the
speed will change in 10 km/h
increments.
By keeping the accelerator pedal
depressed, the vehicle can continue to
accelerate beyond the set speed. In this
case, use the SET switch to set the
speed to the vehicle’s current speed.
When you push the SET button to
reduce the speed, the braking system
intervenes automatically if the engine
brake does not slow the vehicle down
sufficiently to reach the set speed. The
device holds the set speed uphill and
downhill; however a slight variation is
entirely normal, particularly on slight
inclines.
The transmission could change to a
lower gear when driving downhill, or
when accelerating. This is normal and
necessary to maintain the set speed.
The system will disable while driving
if the brakes overheat.
Accelerating When Overtaking
When driving with ACC activated and
following a vehicle, the system will
provide an additional acceleration up to
the ACC set speed to assist in passing the
vehicle. This additional acceleration is
triggered when the driver utilizes the left
turn signal and will only be active when
passing on the left hand side.
The system detects the direction of
traffic automatically when the vehicle
passes from left-hand traffic to
right-hand traffic. In this case, the
overtaking assist function is only active
when the reference vehicle is overtaken
on the right. The additional acceleration
is deactivated when the driver uses the
right turn signal and returns to the
original lane.
Resuming The Speed
Once the system has been canceled but
not deactivated, to resume a previously
set speed, simply push the RES button
and remove your foot from the
accelerator to recall it.
The system will be set to the last stored
speed.
Before returning to the previously set
speed, bring the speed close to that
speed, then push the RES button and
release it.
