OPERATION
Each time the ignition key is removed from
position STOP the protection system activates
the engine immobilizer.
Upon starting the engine, when the key is turned
to MAR:
1) If the code is recognised, the CODE

warning light on the instrument panel turns
off in one second, while the EOBD
warning light turns off after about four
seconds, after the ECU has completed its
diagnostic cycle. The protection system has
recognised the key code and deactivates the
engine immobilizer. With the brake pedal
depressed, pushing the START button, the
engine starts.
2) If the CODE warning light remains on
and the EOBD warning light goes off
after four seconds (ECU diagnostics) and
illuminates again immediately afterwards,
the code has not been recognised and the
message “Electronic key not recognised”
is displayed. In this case, it is advisable to
turn the key back to position STOP and
then back to MAR; If the immobilizer stays
on, try with the other keys. If you are still FUEL TANK DOOR
EMERGENCY OPENING
If necessary, the fuel tank door can be opened
by pulling the cable

compartment, in the beauty case compartment
KEYSTHE ALFA ROMEO CODE
SYSTEM
In order to enhance protection against thefts,
the vehicle is equipped with an electronic engine
immobilizer system (Alfa Romeo CODE), which
is automatically activated when the ignition key
is removed.
Each starter key contains an electronic device
which transmits a code signal to the Alfa Romeo
CODE control unit, and engine ignition is enabled
only if the key code is recognised by the system.
Two keys are provided with the vehicle.
The key is used to:
- start the engine
- activate the central door locking system
- deactivate/activate the passenger airbag
(on vehicles equipped with manual
deactivation system)
- open the rear window
- activate/deactivate the alarm system

STARTING THE
ENGINE
CAUTION
Hold the brake pedal depressed
when starting the engine.
CAUTION
It is dangerous to operate the
engine in an enclosed space. The engine
consumes oxygen and discharges
carbon dioxide, carbon monoxide and
other toxic gases.
WARNING: Before start-up, switch off the
electrical devices with a high power consumption
(air-conditioning and heating system, heated
rear window, headlights, etc.).
WARNING: Do not start the engine if the fuel
level in the tank is low.
1) Make sure that the parking brake is applied
and that the doors are closed.
2) Hold the brake pedal depressed when
starting the engine.
3) Do not depress the accelerator pedal.
4) Set the gear to neutral by pulling both
paddles UP and DOWN towards the
steering wheel and check that the gear
display indicates N not fl ashing.
5) Turn the ignition key to MAR.
6) press button START button and release it as
soon as the engine starts.
Do not hold the START button for a long time.If the engine does not start, turn the key back to
position STOP and wait for the gear display to go
off before retrying.
The engine can also be started with a gear
engaged; turning the key to position MAR, with
the brake pedal depressed, press the START
button. The system allows the clutch to open and
the gearshift to engage neutral gear; then the
starter motor receives clearance for start-up. This
procedure usually requires one second. At very
low temperatures, the procedure could take a
slightly longer time.
If the gearbox is instead in the N position,
starting is immediate.
If the engine does not start after turning the key
to position STOP, wait for the gear display to go
off and then repeat the entire procedure.

WARNING: Do not use a battery-charger for
emergency starting under any circumstances:
you could damage the electronic systems,
particularly the control units that manage the
ignition and fuel supply functions.
CAUTION
Remember that when the
engine is not started, the power
braking and power steering systems
are not activated and so the effort
required on the brake pedal and
steering wheel is much greater.
TURNING OFF THE
ENGINE
With the engine idling, rotate the ignition key to
the STOP position.
A burst on the accelerator pedal before turning
off the engine has no purpose and increases fuel
consumption.
Q-SELECT
GEARBOXThe “Q-Select gearbox” is controlled with
the paddles on the steering wheel for gear
engagement and with the buttons on the centre
console for reverse gear engagement and
activation of the “automatic gearshift” and “low
grip” functions.
The “Q-Select gearbox” controls are the
following:A - Lower gear engagement paddle DOWNB - Upper gear engagement paddle UPC - Reverse gear engagement button

USING THE VEHICLE
CAPACITIESWARNING: Use unleaded fuel only!
The use of fuel containing lead would
permanently damage the catalytic converters.For fluid and lubricant specifications and
quantities, follow the indications contained
in section 7 “CAPACITIES AND TECHNICAL
SPECIFICATIONS”.
SAFE DRIVING
Although the vehicle is fitted with active and
passive safety devices the driver’s behaviour is
always a decisive factor for road safety.
Below are some simple rules for travelling safely
in different conditions. You will, no doubt, be
familiar with some of them but, in any case, it
would be useful to read them carefully.BEFORE YOU DRIVE
- Make sure that the lights and headlights are
working properly.
- Adjust the position of the seat, steering
wheel and rear-view mirrors so that you
have the best driving position.
- Check that nothing (e.g. mat covers, etc.)
is blocking the pedals.
- Carefully arrange any objects in the luggage
compartment, to prevent sudden braking
from jerking them forward.
- Avoid heavy meals before a trip. A light
snack helps to keep the refl exes sharp. In
particular avoid drinking alcohol.
- Remember to read, at regular intervals,
the instructions contained in the chapter
“Before a trip”, in this section.
CAUTION
It is extremely dangerous and
moreover prohibited by law to travel
on the luggage shelf behind the seats.
In the event of an accident, persons
carried in this position are more
exposed to the risk of serious injury.
Passengers must only travel seated in
the vehicle seats, with the seat belts
fastened properly. Always check that
you and your passengers have your
seat belts fastened correctly.

USING THE VEHICLE
ANTI-POLLUTION
DEVICES Even if the vehicle is equipped with anti-pollution
devices, the environment deserves the greatest
respect from every one of us.
By following a few simple rules, the vehicle
driver can avoid damaging the environment and
very often can reduce fuel consumption as well.
In this regard, some useful information is listed
here below; please read it carefully.
The correct operation of the anti-pollution devices
not only assures respect for the environment, but
also has an impact on vehicle performance.
So, keeping these devices in good working
conditions is the first rule for driving that is both
ecologically sound and economical.
The first precaution is to follow the Scheduled
Maintenance plan scrupulously. Always use unleaded fuel.
If starting is difficult, do not make prolonged
attempts.
Especially avoid push starts, towing or hill starts:
these are all manoeuvres that can damage
catalytic converters.
Use an auxiliary battery only when making an
emergency start.
While driving, if the engine does not run
smoothly, you may continue driving but reducing
engine performance to a minimum; you should
then contact an Authorised Service Centre
of the Manufacturer’s Network as soon as
possible.
Never run the engine, even if only for testing,
with one or more spark plugs disconnected.
Do not warm up the engine letting it idle before
starting off, except in the event of very low
outside temperatures and, even then, for no
longer than 30 seconds.
CAUTION
During normal operation the
catalyst converter generates high
temperatures. Do not, therefore, park
the vehicle on flammable materials
(e.g. grass, dry leaves, pine needles,
etc.): risk of fire!
Do not install heat guards and do not remove
those already fitted to the catalytic converter and
to the exhaust manifold.
Do not spray anything on the catalytic converter,
lambda probe and exhaust manifold.
CAUTION
Failure to comply with these
rules can lead to fire hazards.

OTHER ADVICE
- Do not warm up the engine when the
vehicle is stationary: in these conditions
the engine heats up much more slowly and
increases fuel consumption and emissions.
It is much better to move off slowly,
avoiding high engine RPM.
- As soon as traffi c conditions and the route
permit it, use a higher gear.
- Avoid depressing the accelerator repeatedly
during stops at traffi c lights or before
turning off the engine.
- Keep your speed as regular as possible,
avoiding unnecessary brake applications
and accelerations, which cause fuel wastage
and strongly increase exhaust emissions.
- Turn the engine off if the vehicle remains
stationary for a long time. - Check the tyre pressure regularly: if the
pressure is too low, fuel consumption
increases and the tyres are damaged.
- Do not transport unnecessary objects in
the luggage compartment. The weight
of the vehicle affects fuel consumption
considerably.
- Use the electrical devices only as long as
necessary. The power required increases
fuel consumption.
PARKINGPull the electric parking brake, straighten the
wheels and turn off the engine.
Never leave the ignition key in position MAR.
Always remove the key when getting out of the
vehicle.
CAUTION
Never leave children
unattended in the vehicle.
CAUTION
Do not park the vehicle on
paper, grass, dry leaves or other
flammable materials. They could catch
fire if they come into contact with hot
parts of the exhaust system.
CAUTION
Do not leave the engine running
with the vehicle unattended.
