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 = Normal (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). When the engine is stopped, the selector
returns to “n” (Normal) mode.
The symbol of the active mode lights up in red
on the selector.
On the instrument panel display, the different
modes are characterized by different colors:
Normal - Blue
Dynamic - Red
Advanced Efficiency - Green
Mode Display
Each driving mode is graphically different on
color line and contents of each individual
“performance” screen.
Driving Modes
“Dynamic” Mode
Activation
It is activated by rotating the selector to the
letter “d”; the displays light up in red.
Dynamic Mode
ESC and ASR systems: intervention thresholds
that ensure more enjoyable, sportier driving
while guaranteeing the stability of the vehicle.
“Electronic Q2” system: the system is cali -
brated to increase traction while accelerating
on turns, improving the agility of the vehicle.
Engine and transmission: adoption of sports
mapping.
WARNING!
In "Dynamic", the sensitivity of the
accelerator pedal increases considerably.
Consequently, driving is less fluid and
comfortable.
21_GA_OM_EN_USC_t.book Page 99

STARTING AND OPERATING

102

ALFA ACTIVE SUSPENSION
(AAS) — IF EQUIPPED
The system continuously monitors the
damping of the suspension through the actu-
ator 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 sporty 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
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 consump -
tion, gas emissions, and sound pollution.
Operating Mode
Stopping the Engine

With 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
or turn the steering wheel slightly (if
equipped).
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 the brake pressed while the gear selector
is in “AutoStick” mode, the engine will restart
by shifting to PARK (P) or by moving the
selector to + or -.
