“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The “Electronic Q2” system uses the braking system to create an
effect similar to a limited slip differential.
The front braking circuit, when accelerating around a corner, acts
on the inside wheel to increase the drive to the outside wheel (in-
creased load), dynamically and continuously distributing the torque
between the front drive wheels according to driving and road con-
ditions.
The system, combined with Mc Pherson front suspension, allows
particularly effective, sporty driving.
DST SYSTEM (Dynamic Steering Torque)
This function integrates Dual Pinion active steering into the opera-
tion of VDC. For particular manoeuvres, VDC controls the steering
to actuate a steering torque and assist the driver in the best pos-
sible way. The system operates the brakes and steering in a coor-
dinated manner to increase the suspension and safety level of the
car as a whole. The steering provides addition torque on the steer-
ing wheel.
RAB SYSTEM (Ready Alert Brake)
(“Dynamic” mode only)
By pre-approaching the brake pads (front and rear) after rapid ac-
celerator release, this function provides prompter braking and re-
duces stopping distance.
BRAKE ASSIST
(emergency braking assistance)
The system, which cannot be turned off, recognises emergency
braking (on the basis of the brake pedal operating speed) and
speeding up the response of the braking system. The Brake
Assist function is deactivated in the event of VDC system fault.
MSR SYSTEM
(Motor Schleppmoment Regelung)
This system is an integral part of the ABS, that intervenes, if there
is a sudden change to a lower gear, restoring torque to the engine,
thereby preventing excessive drive at the drive wheels which, es-
pecially in poor grip conditions, could lead to a loss in stability.
CBC SYSTEM (Cornering Braking Control)
This system improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking round bends when the ABS intervenes. This improves stop-
ping distances and above all vehicle stability when cornering.

“Alfa DNA” SYSTEM
(Dynamic control system)
This device allows, using switch A-fig. 80 (on the central tunnel),
three response modes to be selected according to driving style
and road conditions:
❍d = Dynamic (for sporty driving)
❍n = Normal (normal driving mode)
❍a = All Weather (driving mode for poor grip conditions, i.e. rain
and snow on the road)
The device also acts on the dynamic vehicle control systems (en-
gine, steering, VDC system, instrument panel).
When the lever A-fig. 80 is moved to “d” position, the activation
of “Dynamic” mode is confirmed by a temporary variation in the
brightness (flashing) of the instrument panel.

DRIVING MODES
Switch A-fig. 80 is a monostable switch, i.e. it always remains in the
central position. The selected driving mode is indicated by the corre-
sponding LED coming on in the panel and by an indication on the re-
configurable multifunction display, as illustrated below:
A0K0009m
A0K0010m
Dynamic mode (display image available for
versions/markets where
provided)All Weather mode
“Normal” mode
When “Normal” mode is selected, no messages or symbols are
shown on the display.
VDCandASR: operating thresholds set for normal comfort lev-
el for normal driving conditions.
Steering tuning: functions aimed at providing comfort in nor-
mal conditions of use.
DST: Standard braking control coordinated with ABS/VDC.
Standard control over lateral acceleration.
Oversteer compensation: a slight pulse on the steering wheel
encourages the driver to carry out the most appropriate ma-
noeuvre.
Engine: Standard responsiveness

TURNING “Dynamic” MODE ON/OFF
On
Move lever A-fig. 80 upwards (to the letter “d”) and hold in this
position for 0.5 seconds until the corresponding LED lights up or
the word “Dynamic” appears on the display (see figures). The
switch A will go back to central position after having been released.Electronic Q2: improves traction and reduces understeer in acce-
leration while exiting curves.
RAB: pre-positioning of the brake pads (front and rear) following
a rapid release of the accelerator pedal to reduce braking
times, shorten stopping distances and improve the feel of
the brake pedal.
The activation of the Dynamic mode is also shown by the change
in the instrument panel lighting that, after decreasing, reaches
the highest luminosity and then returns to the previously set va-
lues.
Off
To turn “Dynamic” mode off and go back to “Normal” mode, move
the lever as described above once again. In this case, the LED cor-
responding to “Normal” mode will light up and the words “Nor-
mal on” will appear on the reconfigurable multifunction display
(see figure).

VDCandASR: intervention thresholds that allow more enjoy-
able, sportier driving whilst guaranteeing stabil-
ity in the event of loss of control. Improves trac-
tion whilst accelerating on bends.
Steering tuning: sports mode operation.
DST:Standard brake control coordinated with ABS/VDC.
Standard control over lateral acceleration
Oversteer compensation adapted to VDC/ASR intervention
thresholds: a slight pulse on the steering wheel encourage
the driver to carry the most appropriate manoeuvre.
Engine: Prompter response + Overboost to maximise torque (for
versions/markets, where provided).
