“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).

On
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.

EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD (European On Board Diagnosis) system is to:
❍to monitor system efficiency;
❍indicate an increase in emissions;
❍to warn of the need to replace deteriorated components.
The car also has a diagnostic connector that can be interfaced
with appropriate tools, which 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 also be carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system com-
pletely, Alfa Romeo Authorized Services are obliged to run tests
and, if necessary, road tests which may also call for a long journey.
DUAL PINION ACTIVE STEERING
This only operates with the key turned to MAR and the engine start-
ed. The steering allows the force required at the steering wheel
to be adjusted to suit driving conditions. The different power as-
sistance modes can be selected via the d,n,a positions of the"Alfa
DNA System" lever (see paragraph entitled "Alfa DNA System").
IMPORTANT The steering system will need to be initialised after
disconnecting the battery. A warning light will come on to indicate
this. Simply turn the steering wheel all the way from one end to the
other or simply drive in a straight line for a few hundred metres.
Under no circumstances should aftermarket op-
erations be carried out involving steering system
or steering column modifications (e.g. installation
of anti-theft device). This could negatively affect perfor-
mance and safety, invalidate the warranty, cause serious
safety problems and also result in non-compliance of the
car with type-approval requirements.

FRONT AIRBAGS
The car is provided with multistage front air bags (“Smart bag”)
for driver and passenger.
“SMART BAG” SYSTEM
(MULTISTAGE FRONT AIR BAGS)
The front driver/passenger air bags are designed to protect occu-
pants in the event of head-on crashes of medium-high severity,
by placing the bag between the occupant and the steering wheel
or dashboard.
Front air bags are designed to protect car’s occupants in front crash-
es and therefore non-activation in other types of collisions (side col-
lisions, rear shunts, roll-overs, etc.) is not a system malfunction.
The air bag do not replace, but rather complement the use of seat
belts, which should always be worn. In the event of an impact,
someone not wearing a seat belt could move forward and come
into contact with a bag which is still in the opening phase. The pro-
tection offered by the bag is reduced in such a case.
Front air bags may not be activated in the following situations:
❍front collisions against highly deformable objects not affect-
ing the front surface of the car (e.g. bumper collision against
guard rail, etc.);
❍car penetration under other vehicles or protective barriers (e.g.
trucks or guard rails);
in these instances they could not provide any additional protec-
tion compared with seat belts, so their deployment would not be
useful. In these cases, non-deployment of the airbag does not
necessarily indicate a system malfunction.
FRONT AIR BAG ON DRIVER’S SIDE fig. 106
This is located in a dedicated compartment in the centre of the steer-
ing wheel.
Do not apply stickers or other objects to the steer-
ing wheel, passenger side air bag cover or upper
side upholstery. Do not place objects on the pas-
senger side dashboard because these could interfere with
the correct opening of the air bag and cause severe injury
to occupants.
fig. 106A0K0080m
Always drive with your hands on the steering wheel
rim so that the air bag can inflate freely if need-
ed. Do not drive with your body bent forward.
Keep your back straight against the backrest.

It is advisable not to demand maximum perfor-
mance from your car (e.g. excessive acceleration,
long distances at top rpm, excessively intense brak-
ing, etc.) when it is first used.
Remember that the brake servo and electro-
mechanical power steering are not operational un-
til the engine has been started, therefore much
more effort than usual is required on the brake pedal and
steering wheel.
Never jump start the engine by pushing, towing or
driving downhill. These manoeuvres may damage
the catalytic converter.
When the engine is switched off never leave the
key in the MAR position to prevent useless cur-
rent absorption from draining the battery.
HOW TO WARM UP THE ENGINE
AFTER IT HAS JUST STARTED
Proceed as follows:
❍drive off slowly, letting the engine turn at medium speed. Do
not accelerate abruptly;
❍do not demand maximum performance for the first few kilo-
metres. Wait until the engine coolant temperature indicator
starts moving.
STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a taxing drive, before turning the engine off you
should allow it to idle to allow the temperature in the engine com-
partment to fall.
A quick burst on the accelerator before turning off
the engine serves absolutely no practical purpose;
it wastes fuel and is especially damaging to tur-
bocharged engines.

The jack may be used to replace wheels only on
the car that it comes with or other cars of the same
model. Never use the jack for other purposes, such
as lifting other models. Never use the jack to carry out re-
pairs under the car. Incorrect positioning of the jack may
cause the car to fall. Do not use the jack for loads higher
than the one shown on its label. Never install snow chains
on the space-saver spare wheel; if a front tyre (driving
wheel) is punctured and you need to use snow chains, use
a standard wheel from the rear axle and install the space-
saver spare wheel on the rear axle. In this way, with two
normal drive wheels, it is possible to use snow chains.
If the hub cap is not fitted correctly, it may come
off when the car is travelling. Never tamper with
the inflation valve. Never introduce tools of any
kind between the rim and the tyre. Regularly check the
inflation pressure of the tyres and space-saver wheel (see
chapter “Technical specifications”).Vehicle handling is modified with the space-saver
spare wheel fitted. Avoid violent acceleration and
braking, sharp steering and fast cornering. The
overall duration of the space-saver spare wheel is of about
3000 km, after which the relevant tyre must be replaced
with another one of the same type. Never install a tradi-
tional tyre on a rim designed to be used as a space-saver
spare wheel. Repair and refit the standard wheel as soon
as possible. Using two or more space-saver spare wheels
at the same time is forbidden. Do not apply grease to
the bolt threads before assembly: they might sponta-
neously unscrew.
JACK
Important notes:
❍the jack weight is 1.76 kg;
❍the jack requires no adjustment;
❍the jack cannot be repaired; if it breaks it must be replaced with
a new jack;
❍no tool other than the cranking device may be fitted on the
jack.
