STARTING AND OPERATING
90
Deactivation
To deactivate the sequential driving mode, bring
the gear selector back in position DRIVE (D)
(“automatic” driving mode).
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
M
ODE
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 transmis -
sion will return to normal operation.
NOTE:
Even if the transmission can be reset, we recom -
mend that you visit an authorized dealer at your
earliest possible convenience. An authorized
dealer has diagnostic equipment to determine if
the problem could reoccur. If the transmission
cannot be reset, service is required at an autho -
rized dealer.
BRAKE/TRANSMISSION SHIFT INTERLOCK
(BTSI) S
YSTEM
This vehicle is equipped with a BTSI system 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 placed in the ON/RUN 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), place the
vehicle in the NEUTRAL (N) position when
stopping the engine. See the following steps:
1. Vehicle at a standstill.
2. NEUTRAL (N) mode activated.
3. Push the ignition button for at least three
seconds.
The automatic parking brake engagement
function 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 the following 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 press the brake pedal.
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.

ALFA DNA / PRO SELECTOR
ALFA DNA SYSTEM
This vehicle is equipped with an Alfa DNA system
selector (located on the center console). There
are four modes of operation to be selected
according to driving style and road conditions:Alfa DNA System Selector
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 (if equipped).
= Adjusts the calibration of the active
suspension (Quadrifoglio only).
Unlike the other modes, there is no detent for the
RACE position. When the system selector is
rotated to the RACE position, it will return to its
initial position "d".
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 parking brake, shift
the transmission into PARK, and turn the
ignition OFF. When the ignition is in the OFF
position, the transmission is locked in PARK,
securing the vehicle against unwanted
movement.
When leaving the vehicle, always make sure
the ignition is in the OFF position, 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 ON/RUN or
ACC position. A child could operate power
windows, other controls, or move the vehicle.
CAUTION!
Only engage the gear with engine at idling
while fully pressing 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.
WARNING!

NOTE:
If the brake system overheats, this is communi
-
cated by the Information and Entertainment
system. In this case, allow the system to cool for
a few minutes by driving the vehicle normally
without operating the brakes.
Deactivation
To deactivate the RACE mode, rotate the selector
to the RACE position again and the system will be
set to “d” Dynamic mode.
ALFA ACTIVE SUSPENSION
(AAS) — IF EQUIPPED
The system continuously monitors the damping
of the suspension through the actuator installed
on each shock absorber. 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 handling. The driver can choose, while driving (only in “d” or
“RACE” mode), between two types of suspension
calibration: a more sportier or a more
comfortable type.
By pushing the button, the system prepares the
shock absorber calibration in order to favor
driving comfort.
“Alfa DNA” System Selector
In case of a system failure, the symbol and a
dedicated message will be shown on the
instrument cluster 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
pressing the accelerator pedal will automatically
restart the engine.
The function was designed 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.
WARNING!
Only activate the RACE mode at the track.
In “RACE”, the sensitivity of the accelerator
pedal increases considerably. Consequently,
driving is less fluid and comfortable. The
driver must ensure full control of the vehicle
at all times to avoid a collision.

STARTING AND OPERATING
98
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always
be aware of the feature selected.
Only one Cruise Control feature can operate at
a time. For example, if Fixed Speed Cruise
Control is enabled, Adaptive Cruise Control will
be unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).Cruise Control On/Off Switch
The Cruise Control buttons are located on the left
side of the steering wheel.
While driving downhill, the system could brake
the vehicle to keep the set speed the same.To Activate
To activate the Cruise Control system, push the
on/off button located on the left side of the
steering wheel.
The activation of the system is signaled by the
illumination of the white indicator light on the
instrument cluster.
Cruise Control Indicator Light
The Cruise Control function can remain active at
the same time as the Speed Limiter system. If the
set speed is higher than the speed set with the
Speed Limiter, the set speed will be lowered to
that of the Speed Limiter. For Quadrifoglio vehicles, this function remains
available in RACE mode.
NOTE:
The system cannot be engaged in FIRST or
REVERSE gear. It is advisable to engage it in
THIRD gear or higher if using the AutoStick
feature.
To Set A Desired Speed
To set a desired speed, proceed as follows:
1. Turn the Cruise Control on.
2. When the vehicle has reached the desired
speed, push the SET switch up or down and
release to activate. When the accelerator is
released, the vehicle will maintain the
selected speed automatically.
SET Switch Location
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
WARNING!
Leaving the Cruise Control 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 an
accident. Always ensure the system is OFF
when you are not using it.

If needed (when overtaking for instance), you can
accelerate beyond the set speed by pressing the
accelerator. When you release the pedal, the
vehicle will return to the previously set speed.
When traveling downhill with the system active,
the vehicle speed may slightly exceed the set one.
NOTE:
Before pushing the SET switch, the vehicle must
be traveling at a constant speed on a flat surface.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase
the speed by pushing the SET switch upward or
decrease the speed by pushing the SET switch
downward.
U.S. Speed (mph)
Pushing the SET switch once will result in a
1 mph speed adjustment. Each subsequent
movement of the switch results in an
adjustment of 1 mph.
If the switch is continually pushed, the set
speed will continue to adjust until the switch is
released, then the new set speed will be
established.
Metric Speed (km/h)
Pushing the SET switch once will result in a
1 km/h speed adjustment. Each subsequent
movement of the switch results in an
adjustment of 1 km/h.
If the switch is continually pushed, the set
speed will continue to adjust until the switch is
released, then the new set speed will be
established.
NOTE:
Moving the SET switch allows for adjusting of the
speed according to the selected unit of measure -
ment set on the radio system. Refer to the Infor -
mation and Entertainment System Owner’s
Manual for more information.
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
Using Cruise Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up
and down hills. A slight speed change on
moderate hills is normal. On steep hills, a greater
speed loss or gain may occur so it may be
preferable to drive without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
NOTE:
Before resuming the previously set speed, you
must accelerate to a speed close to that speed.
Resume Button Location
In AutoStick (sequential) mode, before resuming
the previously set speed, you should accelerate
until you are close to that speed. Then, push and
release the RES button.
To Deactivate
A tap on the brake pedal deactivates the Cruise
Control without deleting the set speed.
The Cruise Control may also be deactivated by
applying the Electric Park Brake or when the
braking system is operated (e.g. operation of the
Electronic Stability Control (ESC) system).
The set speed is deleted in the following cases:
Pushing the on/off button a second time
The ignition is placed in the OFF position
If there is a malfunction with the Cruise Control
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.

(Continued)
ADAPTIVE CRUISE CONTROL (ACC)
The Adaptive Cruise Control (ACC) is a driver
assist system that combines the Cruise Control
functions with controlling the distance from the
vehicle ahead. ACC will adjust the vehicle speed
up to the preset speed to maintain a distance
with the vehicle ahead. ACC increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not
designed to prevent collisions. The Cruise Control
function performs differently
Ú
page 98.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
uses a radar sensor located behind the front
bumper and a camera located in the center/
upper part of the windshield, to detect the
presence of a vehicle close ahead.
The system sets and holds the vehicle at the
desired speed without needing to press the
accelerator. It also sets and holds a distance
from the vehicle ahead (these settings are set by
the driver). Front Bumper Radar Location
Windshield Camera Location
If the system detects a vehicle ahead, it will
automatically intervene by slightly braking or
accelerating in order to maintain the preset
distance. It will not exceed the original set speed
when adapting to the speed of the vehicle ahead.
NOTE:
Adaptive Cruise Control performance is not guar -
anteed under the following circumstances. You
should not utilize the ACC system when:
Driving in fog, heavy rain, sleet, or snow.
Driving in heavy traffic and complex driving
situations (e.g., in construction zones).
Driving on icy, snowy, slippery roads, roads
with steep inclines or downhill slopes, or roads
with numerous turns and bends.
Entering a turn lane or highway off-ramp.
When circumstances do not allow safe driving
at a constant speed
Ú
page 239.
WARNING!
Adaptive Cruise Control (ACC) is a
convenience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of road,
traffic, and weather conditions, vehicle
speed, distance to the vehicle ahead 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 and
death or serious personal injury.
The ACC system:
• Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a stopped vehicle in a traffic jam or a disabled vehicle).
23_GA_OM_EN_USC_t.book Page 100

101
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is
19 mph (30 km/h) and the maximum is 110 mph
(180 km/h).
The system cannot be activated:
When pressing the brake pedal.
When the brakes are overheated.
When the Electric Park Brake has been
operated.
When either PARK, REVERSE or NEUTRAL is
engaged.
When the engine RPM is above a maximum
threshold.
When the vehicle speed is not within the
operational speed range.
When the Electronic Stability Control (ESC) (or
Anti-Lock Brake System (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 a 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.
The driver should always obey traffic laws and
speed limits. Never drive above applicable speed
limit restrictions.
To Activate/Deactivate
The system has four operating states:
Enabled (speed not set)
Activated (speed set)
Paused
Deactivated
To Activate
To enable the system, push and release the on/
off button located on the left side on the steering
wheel.
On/Off Button
•
Cannot take street, traffic, and weather
conditions into account, and may be limited upon adverse sight distance conditions.
• Does not always fully recognize complex
driving conditions, which can result in wrong or missing distance warnings.
• Will bring the vehicle to a complete stop
while following a vehicle ah ead and hold
the ve
hicle for approximately two
minutes in the stop position. If the vehicle ahead does not start movingwithin two minutes, the parking brakewill be activated and the ACC system will be canceled.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex driving situations (i.e., in highwayconstruction zones).
• When entering a turn lane or highway
off-ramp; w hen driving on roads that are
win d
ing, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
• When circumstances do not allow safe
driving at a constant speed.
WARNING!

STARTING AND OPERATING
102
When the system is enabled and ready to
operate, the display shows the white ACC icon
above dashes in place of the speed.Enabled Icons
Setting a speed activates the system. The display
shows the icon in green with the set speed.
To Pause/Deactivate
With the feature enabled (speed not set), push
the on/off button to disable.
With the feature active (speed set), push the on/
off button to pause. The display will show the icon
in white with the speed in brackets. To deactivate
the feature, push the on/off button a second
time.To Set A Desired Speed
When the vehicle reaches the desired speed,
push the RES/SET switch downward and release
it to activate the system. When the accelerator is
released, the vehicle will maintain the set speed
automatically.
SET Switch
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.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
Once the system has been activated, you can
increase the speed by pushing the RES/SET
switch upward or decrease the speed by pushing
the RES/SET switch downward. Each time the
switch is pushed, the speed is adjusted by 1 mph.
Pushing and holding the switch upward or
downward will cause the set speed to adjust in
5 mph increments until the button is released. The new set speed is reflected in the instrument
cluster display.
NOTE:
Moving the RES/SET switch downward allows
you to adjust the speed according to the
selected unit of measurement ("U.S." or
"Metric") set on the radio system. Refer to the
Information and Entertainment System
Owner’s Manual Supplement for further
information.
When the unit of measurement is set to Metric,
pushing and holding the RES/SET switch will
adjust the speed in 10 km/h increments.
By keeping the accelerator pedal pressed, the
vehicle can continue to accelerate beyond the
set speed. In this case, use the RES/SET
switch to set the speed to the vehicle’s current
speed.
When you push the RES/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 shift 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.
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.

(Continued)
To Resume
Once the system has been canceled but not
deactivated, to resume a previously set speed,
simply push the RES/SET switch upward and
remove your foot from the accelerator to recall it.
The system will be set to the last stored speed.
Setting The Distance Between Vehicles
The distance between your vehicle and the
vehicle ahead may be set to one bar (short), two
bars (medium), three bars (long), or four bars
(maximum).Distance Icons The distances from the vehicle ahead are propor
-
tional to speed.
The interval of time with relation to the vehicle
ahead remains constant and varies from one
second (for the short distance one-bar setting) to
two seconds (for the maximum distance four-bar
setting).
The set distance is shown on the display by a
dedicated icon.
The setting is four bars (maximum) the first time
the system is used. After the distance has been
modified by the driver, the new distance will be
stored even if the system is deactivated and
reactivated.
To Decrease The Distance
Push and release the distance button to decrease
the distance setting. The distance setting
decreases by one bar (shorter) every time the
button is pushed.
Distance Button
The set speed is held if there are no vehicles
ahead. Once the shortest distance has been
selected, the next push of the button will set the
maximum distance. If a slower vehicle is detected in the same lane,
the vehicle icon on the display illuminates from
grey to white. The system automatically adjusts
the vehicle’s speed to keep the set distance,
independently of the set speed.
The vehicle holds the set distance until:
The vehicle ahead accelerates to a speed
higher than the set speed.
The vehicle ahead leaves the lane or the
detection field of the Adaptive Cruise Control
system sensor.
The distance setting is changed.
The Adaptive Cruise Control system is
deactivated/paused.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to follow
these warnings can result in a collision and
death or serious personal injury.
WARNING!
The maximum braking applied by the system
is limited. The driver may apply the brakes in
all cases if needed.
If the system predicts that the braking level is
insufficient to hold the set distance, either
“BRAKE!” or a dedicated message is
displayed to warn the driver of approaching
the vehicle ahead. An acoustic signal is also
emitted. In this case, it is advised to brake
immediately as necessary to hold a safe
distance from the vehicle ahead.
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.
