INCREASING THE STORED SPEED
Press the accelerator and store the new speed or move the stalk
upwards (+). Each movement of the stalk will correspond to an
increase in speed of about 1 km/h, while keeping the stalk held
upwards the speed will continuously increase.
REDUCING THE STORED SPEED
Deactivate the device and store the new speed or move the stalk
downwards (–) until the new speed is reached. It will then auto-
matically be stored. Each movement of the stalk will correspond
to a reduction in speed of about 1 km/h, while keeping the stalk
held downwards will continuously reduce the speed.
TURNING THE DEVICE OFF
To release:
❍turn the A ring fig. 43 to OFF;
or
❍stop the engine;
or
❍press the brake pedal, the clutch or the accelerator; in this
last case the system is not actually turned off but the system
gives priority to the acceleration request. The device still re-
mains active, without the need to press the RES button to re-
turn to the previous condition once acceleration is concluded.
STORING THE SPEED
Proceed as follows:
❍turn A ring fig. 43 to ON and press the accelerator until the
car reaches the desired speed;
❍move the stalk upwards (+) for at least one second, then re-
lease it. The speed is now stored and you can therefore release
the accelerator pedal.
If needed (when overtaking for instance), you can accelerate sim-
ply by pressing the accelerator pedal; when you come off the ped-
al, the car will return to the speed memorised previously.
RESTORING STORED SPEED
If the device was disengaged - for example by pressing the brake
or clutch pedal - the stored speed can be reset as follows:
❍accelerate gradually until reaching a speed approaching the one
stored;
❍engage the gear selected at the time of speed storing;
❍press RES button (B-fig. 43).

ASR SYSTEM (AntiSlip Regulation)
It is an integral part of the VDC system. It intervenes automatical-
ly if one or both of the drive wheels is slipping, there is a loss in
grip on a wet surface (aquaplaning), acceleration on slippery, snow-
covered or icy surfaces, etc.
Depending on how slippery the road is, two different control sys-
tems are activated:
❍if the slipping involves both drive wheels, the ASR intervenes
reducing the power transmitted by the engine;
❍if the slipping only involves one of the drive wheels, the ASR
intervenes automatically braking the wheel that is slipping.
In order for the ESP and ASR systems to operate
correctly, it is essential that the tyres are of the
same brand and type on all wheels, in perfect con-
dition and, above all, of the specified type, brand and size.
If the space saver wheel is used, the VDC system
keeps operating. Be aware however that the space
saver wheel, being smaller than the original wheel,
provides less grip.
The performance of the VDC and ASR systems
should not encourage the driver to take unneces-
sary risks. Your driving style should always take
road conditions, visibility and traffic into account. The dri-
ver is always ultimately responsible for road safety.

“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

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).

To disengage “All Weather” mode and return to “Normal”, carry
out the same procedure described for“Dynamic” mode, however
moving lever A-fig. 80 to “a”.
IMPORTANT
❍It is not possible to go directly from “Dynamic” mode to “All
Weather” mode and vice versa. You must always first go back
to “Normal” mode and then select the other mode.
❍“Dynamic” mode was engaged when the engine was switched
off, the next time it is started “Normal” mode is automatical-
ly selected. If, however, “All Weather” or “Normal”, was en-
gaged when the engine was switched off, the selected mode
is maintained the next time it is started.
❍“Dynamic” mode cannot be engaged at speeds of above 110
km/h.
❍In the event of system failure or a fault with lever A-fig. 80,
no driving modes can be selected. The display will show a warn-
ing message.

The ultimate responsibility when parking and car-
rying out other dangerous manoeuvres still rests
with the driver. When carrying out such manoeu-
vres, always ensure that the manoeuvring area is free
of people (particularly children) and animals. Parking sen-
sors are designed to assist drivers; however, you must al-
ways concentrate fully during potentially dangerous ma-
noeuvres, even if carried out at low speeds.
GENERAL WARNINGS
During parking manoeuvres, pay the utmost attention to any ob-
stacles that could be located above or below the sensors.
Sometimes, objects located close to the rear part of the car may
not be detected by the system and may damage the car or become
damaged themselves.
Here below are some conditions that may influence the perfor-
mance of the parking system:
❍Reduced sensor sensitivity and a reduction in the parking as-
sistance system performance could be due to the presence on
the surface of the sensor of: ice, snow, mud, thick paint.
❍the sensor may detect a non-existent obstacle (echo noise) due
to mechanical noises, for example when washing the vehicle,
in case of rain, strong wind, hail.
❍the signals sent by the sensors can also be altered by the pres-
ence of ultrasound devices (e.g. pneumatic brake systems or
pneumatic drills) near the car;
❍sensor performance can also be influenced by the position of
the sensors. For example by a change in the ride setting (caused
by the wear of the shock absorbers, suspension), overloading
the car and carrying out specific tuning operations that require
the car to be lowered;
❍the detection of obstacles at the top part of the vehicle may
not be guaranteed because the system detects obstacles that
could cause an impact with the vehicle in the bottom part.
For repainting the bumpers or retouching the paint-
work around the sensors contact Alfa Romeo
Authorized Services. Incorrect application of paint
may compromise the operation of the parking sensors.

Front seats (warning light no. 1 = driver and
no. 5 = passenger)
Driver
If the driver is the only occupant and the seat belt is not fastened,
when 20 km/h is exceeded or when travelling at a speed from 10
to 20 km/h for longer than 5 seconds, an acoustic signal sequence
will be started (front seats) consisting of a tone for 6 seconds fol-
lowed by a 90 second beep. The warning light will blink. Once the
cycle is complete, the warning lights stay on with a fixed light un-
til the car is turned off. The acoustic signal will be interrupted im-
mediately when the driver’s seat belt is fastened and the warning
light will turn green.
If the seat belt is again unfastened when the car is in motion, the
acoustic signal and the red warning light blinking resume as de-
scribed previously.
Passenger
A similar solution applies for the front passenger, with the differ-
ence that the warning light turns green and the signal is interrupted
also when the passenger leaves the car.
If both front seat belts are unfastened with the car in motion a few
seconds apart, the acoustic signal will refer to the most recent event
while the two warning lights will issue a visual signal independently.
Rear seats (warning light no. 2, no. 3
and no. 4)
The signalling cycle is run only when any rear seat belt is unfas-
tened (blinking red). In this condition, the warning light referred
to the seat belt which has been unfastened will start blinking (red)
for approximately 30 seconds. An acoustic signal will also sound.
The visual signal (blinking red) will start and end independently for
each warning light if several seat belts are unfastened. The visual
signal will turn green after the corresponding seat has been fas-
tened.
The rear seat warning lights will go out, regardless of the state of
the belt (red or green) approximately 30 seconds after the last sig-
nal.
WARNINGS
All warning lights will remain off if all the seat belts (front and rear)
are already fastened when the key it turned to MAR.
All the warning lights will come on when at least one belt changes
from fastened to unfastened status or vice versa.
