MAIN BEAM HEADLIGHTS
With A ring in position 2pull the stalk towards the steering wheel
(stable position). The warning light
1on the instrument panel
will come on. To turn the lights off, pull the stalk again towards
the steering wheel (dipped beam headlights will stay on). It is
not possible to switch on the main beam headlights in fixed mode
if the automatic lighting control system is active.
FLASHINGS
Pull the stalk towards the steering wheel (unstable position) re-
gardless of the position of A ring. The
1warning light will come
on in the instrument panel.
DIRECTION INDICATORS
Put the stalk in the stable position:
❍upward: activation of right direction indicator;
❍downward: activation of left direction indicator.
Lights
¥orÎwill flash on the instrument panel. The direction in-
dicators are switched off automatically when the steering wheel
is straightened.
“Lane change” function
If you want to signal that you are changing lane, hold the left stalk
in the unstable position for less than half a second. The direction
indicator on the selected side flashes five times and then switch-
es off automatically. IMPORTANT The sensor is unable to detect the presence of fog. Un-
der these circumstances, these lights are therefore turned on man-
ually.
When the lights are turned on by the sensor, the fog lights (for ver-
sions/markets, where provided) and the rear fog lights may be
turned on. When the lights are automatically switched off, the front
and rear fog lights (if activated) are also switched off. The next
time the lights are switched on automatically, the fog lights must
be reactivated manually (if required).
With the sensor active, it is possible to flash the headlights but
the main beam headlights cannot be switched on. If you need to
turn these lights on, turn A ring fig. 40 to position
2and turn
the dipped beam headlights on.
When the lights have been activated automatically and are then
switched off by the sensor, the dipped beam headlights are switched
off first, followed by the side lights a few seconds later.
If the sensor is activated but is malfunctioning, the side lights and
dipped beam headlights are switched on independently of the out-
side light level and the sensor fault is indicated on the instrument
panel display. It is also possible to deactivate the sensor and switch
on these light.

“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.

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).

SNOW TYRES
Use snow tyres of the same size as the normal tyres provided
with the car. Alfa Romeo Authorized Services will advise you on the
most appropriate tyre for use.
Only use these tyres in the event of ice or snow on the roads.
For the type, pressures and specifications of the snow tyre to be
used, follow carefully the instructions given in the “Wheels” para-
graph of the “Technical specifications” chapter.
The performance of these tyres is considerably reduced when the
tread depth is less than 4 mm. If this is the case, replace them.
Due to their specific features, the performance of snow tyres is
much lower than that of standard tyres in normal conditions or on
long motorway stretches. You should therefore use them only in
the conditions for which they were designed. All four tyres should be the same (brand and track) to ensure greater
safety when driving, during braking and better driveability. Re-
member that it is inappropriate to change the direction of rotation
of tyres.
The maximum speed for snow tyres marked “Q”
is 160 km/h, while it is 190 km/h for “T” tyres
and 210 km/h for “H” tyres. You should, howev-
er, always stick to the speed limits of the highway code.

The space-saver spare wheel is vehicle-specific:
do not use it on vehicles of other model and do not
use space-saver spare wheels from other models
on your car. The space-saver spare wheel must only be
used in an emergency. Never use it longer than strictly
necessary and never exceed 80 km/h. On the space-saver
spare wheel there is a label, summarizing the main warn-
ings about the space-saver spare wheel usage restrictions.
Never remove or cover the label. Never apply any hub
cap to the space-saver spare wheel.
CHANGING A TYRE
GENERAL INSTRUCTIONS
The car is equipped with an “Automatic Fix&Go Kit“: see “Auto-
matic Fix&Go Kit” for how to use this device.
Alternatively to the “Automatic Fix&Go Kit” the car may be
equipped with a space-saver spare wheel: see the instructions on
the following pages for changing the tyre.
Use your hazard lights, warning triangle, etc. to
show that your car is stationary in compliance with
regulations. Passengers should get out of the car,
particularly if it is heavily loaded, and wait for the wheel
to be changed away from the traffic. In the event of a
wheel change on a slope or on unsurfaced roads, chock
the wheels.
BUMP STARTING
Never start the engine by pushing, towing or driving downhill.
Never use a fast battery-charger to start the en-
gine as this could damage the electronic systems
of your car, particularly the ignition and fuel sup-
ply control units.

plastic aerodynamic guard;
❍operate the device A-fig. 116 so as to extend the jack, until the
upper part B-fig. 117 is inserted correctly inside the device C;
❍warn anybody nearby that the car is about to be lifted. They
must stay clear and not touch the car until it is back on the
ground;
❍fit the handle D-fig. 116 in the seat in device A, operate the
jack and lift the car until the wheel to be changed is several
centimetres off the ground;
❍for versions with wheel cap, remove the wheel cap after loos-
ening the 4 fastening bolts and finally loosen the fifth bolt and
extract the wheel;
❍make sure the contact surfaces between space-saver spare
wheel and hub are clean so that the fastening bolts will not
come loose;
❍fit the space-saver spare wheel by inserting the first bolt for two
threads into the hole closest to the valve;

WHEELS AND TYRES
Before embarking on a long trip, and every two weeks, check the
tyre inflation pressure (and space-saver wheel); check the pressure
with the tyres cold.
It is normal for the pressure to increase when the car is used; for
the correct tyre inflation pressure, see “Wheels” in the “Technical
specifications” section.
Incorrect pressure causes abnormal tyre wear fig. 165:
A normal pressure: tread evenly worn.
B low pressure: tread particularly worn at the edges.
C high pressure: tread particularly worn in the centre.
The tyres must be replaced when the tread is less than 1.6 mm
thick.IMPORTANT NOTES
Take the following precautions to prevent damage to the tyres: ❍avoid braking suddenly, racing starts and violent impact against
the curb, potholes or other obstacles and driving for extended
periods on unsurfaced roads;
❍check the tyres regularly for cuts on the sides, swelling or ir-
regular tread wear;
❍avoid travelling with the vehicle overloaded. If you puncture a
tyre, stop immediately and replace it;
❍have the tyres checked by specialised personnel if they have
been fitted for longer than 6 years. Remember to check the
space-saver wheel very carefully;
❍change the position of the tyres every 10-15 thousand kilo-
metres, keeping them on the same side of the vehicle to avoid
inverting the direction of rotation.
❍a tyre will age even if it is not used much. Cracks in the tread
and on the sidewalls are a sign of ageing. In any event, have
the tyres checked by specialised personnel if they have been
fitted for longer than six years. Remember to check the space-
saver wheel very carefully;
❍when replacing the tyres, always fit new tyres, avoiding those
of dubious origin;
❍If a tyre is replaced, you should also change the inflation valve.
