ONBOARD DIAGNOSTIC
SYSTEM
Operation
The Onboard Diagnostic system (OBD) carries out
a continuous diagnosis of the components of the
vehicle related to emissions.
It also alerts the driver of when these
components are no longer in peak condition by
switching on the warning light on the
instrument panel

Ú
page 70.
The aim of the OBD system (Onboard Diagnostic)
is to:
Monitor the efficiency of the system
Indicate an increase in emissions
Indicate the need to replace damaged
components
The vehicle also has a connector, which can
interface with appropriate tools, that makes it
possible to read the error codes stored in the
electronic control units together with a series of
specific parameters for engine operation and
diagnosis. This check can be carried out by an
authorized dealer.

NOTE:
After eliminating a fault, to check the system
completely, an authorized dealer is obliged to run
tests and, if necessary certain road tests.

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!

“RACE” Mode (Quadrifoglio Only)
Activation
It is activated by rotating the selector to position
“RACE”; the displays light up in yellow.RACE Mode
Engine and transmission: adoption of sports
mapping.
The “Performance” screen displays parameters
related to vehicle stability, the graphs illustrate
the trend of the longitudinal/lateral accelerations
(G-meter information), considering gravity
acceleration as a reference unit.
The screen displays the lateral and longitudinal
acceleration peaks. RACE Mode Performance Display

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.

TRAFFIC JAM ASSIST (TJA)
SYSTEM — IF EQUIPPED
The Traffic Jam Assist (TJA) system can be
activated on all road types. The system uses a
camera and radar sensors located on the front
fascia/bumper to detect lane markings and keep
the vehicle in the center of the lane.
When the system is unable to detect lane
markings, it will still operate using surrounding
traffic. This can occur in congested traffic
scenarios, when the vehicles ahead or
surrounding obstruct the visibility of the lane
markings. When the speed is below 12 mph
(20 km/h), the system can use a lock-on strategy
that allows the vehicle to automatically follow the
vehicle ahead.
The TJA system combines Adaptive Cruise Control
(ACC) functions with Lane Departure Warning
functions to maintain vehicle speed and steering
wheel behavior.

NOTE:
Do not use the TJA system while driving in urban
areas.
TO ACTIVATE/DEACTIVATE
To activate the system, push the button on the
left side of the steering wheel.
To deactivate the system, push the button again.Traffic Jam Assist Button Suspension Conditions
The following operations will suspend the TJA
system:
Pressing the brake pedal
Opening the driver’s door
Disabling ACC

If the vehicle speed exceeds 37 mph (60 km/h)

Releasing the driver’s seat belt
Placing the gear selector in PARK, REVERSE, or
NEUTRAL
If the Forward Collision Warning system or
“Active Braking” intervenes
Automatic Deactivation
System operation will be temporarily disabled
under the following conditions:
When traveling around narrow bends
If the lane boundaries are not detected
One of the two lines is interrupted
The sun is low and reflects on the radar
camera
If the turn signals are activated
If the driver intentionally changes lanes
without using the turn signal
If manual steering begins
If the driver’s hands are removed from the
steering wheel
When there is no surrounding traffic and there
are no horizontal lane boundaries
If the system is not functioning properly
If lateral acceleration is high
ALWAYS obey traffic laws and pay attention
to the road. ALWAYS drive safely with your
hands on the steering wheel. You have full
responsibility and assume all risks related to
the use of the features and applications in
this vehicle. Only use the features and
applications when it is safe to do so. Failure
to do so may result in an accident involving
serious injury or death.
WARNING!
WARNING!
You should switch off the TJA system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving
situations (i.e., in highway construction
zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When circumstances do not allow safe
