ELECTRONIC
ALARM SYSTEMThe electronic alarm system has the following
functions:
- remote control of the centralised door
locking/unlocking system
- perimeter surveillance, detecting the
opening of doors, engine/luggage
compartment lids
- motion surveillance, detecting intrusion in
the passenger compartment
- vehicle movement surveillance.WARNING: The engine immobilizer function is
ensured by the Alfa Romeo CODE system, which
is automatically activated when the ignition key
is removed from the starter switch.
ACTIVATION
Press button
A on the key to activate the alarm
system:
- the direction indicators fl ash once
- the system beeps;
- the centralised door locking of the vehicle is
activated and doors are locked.
The alarm system is active after approximately
25 seconds and the alarm is activated when:
- a door is opened
- the luggage compartment lid is opened
- the engine compartment lid is opened
- someone attempts to enter the vehicle from
a window
- the power supply is disconnected
- the siren is disconnected
- the vehicle is moved.When the alarm is active, the user may request
the luggage compartment opening; in this
case, the motion and inclination sensors are
temporarily deactivated.
If the luggage compartment is then closed, the
sensors will be reactivated.
Should the direction indicators flash 9 times
when you activate the alarm system, this means
that one of the doors or lids is not properly closed
and therefore is not protected by the perimeter
surveillance. Check for correct closing of doors,
luggage/engine compartment lid and close the
open one without deactivating the alarm system:
direction indicators flashing once indicate that
now the door, luggage/engine compartment
lid are closed properly and are protected by the
perimeter surveillance.

B
BEFORE YOU DRIVE
WARNING: If the direction indicators flash 9
times when the alarm system is activated with
doors, front and rear lids properly closed, this
means that the self-diagnostic function has
detected a malfunction in the system and that
you should contact an Authorised Service
Centre of the Manufacturer’s Network to have
the system checked.
DEACTIVATION
Press button
B on the key to deactivate the
alarm system:
- the direction indicators will fl ash twice
- the system emits a double beep
- the centralised door locking system is
activated and the doors are unlocked.
The alarm system is off and it is therefore
possible to get into the vehicle and to start the
engine.Press button
B twice to unlock all the doors; the
low beams will activate for 30 seconds.
WARNING: The alarm system is not deactivated
when the key is turned in the locks.GETTING INTO THE
VEHICLE WHEN THE
ALARM SYSTEM IS ON
When the remote control battery is flat, to access
the vehicle you must insert the key in the lock on
one of the two front doors and turn it clockwise
to unlock it: the alarm will sound but you will
have to continue with the normal starting
procedure. The alarm will go off.

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.

USING THE VEHICLE
REQUESTING
NEUTRAL (N)
If necessary, neutral (N) can be requested at any
speed.
If you then operate the UP paddle, the system
will engage a gear suited to the vehicle speed.
STOPPING THE VEHICLE
When the vehicle stops, the system
automatically engages 1
st gear (unless N has
already bee requested).
With the vehicle stationary and the engine
running, hold the brake pedal depressed until
you are ready to start off again. TURNING OFF
THE ENGINE AND
DEACTIVATING THE
SYSTEM
The engine can only be turned off with the
gearbox in 1
st, or reverse gear R.
If the gear is in neutral and the key is turned
from MAR to position STOP, the display remains
on for a few seconds showing the letter (N)
flashing and activating the acoustic signal.
For safety reasons, to avoid undesired and
sudden vehicle movements:
CAUTION
Never leave the vehicle with
the gear in neutral (N), but engage
1
st or reverse gear and check that the
parking brake has been engaged. Do
not leave the vehicle with the engine
running.CAUTION
Do not remove the key when
the vehicle is moving! The system (and
thus the display) would remain active
but malfunctioning, until the vehicle
stops; in addition, the steering wheel
would lock automatically at the first
turn of the wheel.
In this case, the failure symbol
will
illuminate and, before starting-off again, the
system must be turned off and the “system start-
up” phase repeated.
In any event, it is best to:
- Turn off the engine and the system holding
the brake pedal depressed.
- Do not request a gearshift while the system
is turning off.

USING THE VEHICLE
USING THE
ENGINEBREAKING-IN
The latest methods of production provide high
precision in the construction and coupling of
components. However, the moving parts do
undergo a settling process, basically in the first
hours of vehicle operation.
ENGINE AND
TRANSMISSION
Avoid exceeding 5000 RPM for the first 1000
km.
After starting the vehicle, do not exceed 4000
RPM until the engine has warmed up sufficiently
(water temperature: 65, 70 °C).
Do not let the engine run at a constantly high
RPM for a prolonged time.WHILE DRIVING
Never travel with the Rev. Counter indicator
approaching the peak RPM - not even downhill.
When the revolution counter indicator is
approaching the peak RPM, drive carefully to
avoid exceeding this limit.
WARNING: In normal conditions all the red
warning lights on the instrument panel and on
the display must be off. When they illuminate,
they indicate a problem in the relative system.Ensure proper operation of the various devices by
checking the relative control gauges.
WARNING: Continuing to drive when a red
warning light is on could cause serious damage
to the vehicle and affect performance.
CAUTION
Never turn the engine off
while driving downhill as the vacuum
decrease prevents the servo brake
from functioning correctly. After a few
braking attempts, the system will
become almost completely inefficient.
The power steering will also loose its
efficiency in these condition.

USING THE VEHICLE
RESETTING THE SPEED
STORED IN THE MEMORY
The speed stored in the memory is automatically
zero-reset:
- by turning the engine off
or
- by setting the switch
A to OFF.
CAUTION
When driving with Cruise
Control activated, do not shift to
neutral. It is advisable to activate
Cruise Control only when traffic and
road conditions permit safe use of
this device, that is: on straight and
dry roads, expressways or highways,
smooth-flowing traffic and smooth
asphalt. Do not activate the device in
the city or in heavy traffic.CAUTION
Cruise Control can only be
activated at speeds exceeding 30
km/h.
CAUTION
The device can only be turned
on in 4
th 5th or 6
th gear, depending on
the vehicle speed.
CAUTION
When driving downhill with
the device active, the vehicle may
pick up speed slightly exceeding the
speed stored in the memory due to the
change in engine load.
CAUTION
If the device malfunctions or
fails to operate, set the switch A to
OFF and contact an Authorised Service
Centre of the Manufacturer’s Network
after checking that the protection fuse
has not blown.CAUTION
Switch A can be left on the ON
position at all times, without damaging
the device. In any case, it is advisable
to deactivate the device when it is
not in use. Move switch A to the OFF
position to prevent speeds from being
unintentionally stored.

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.

B
Engagement
The electric parking brake is automatically
applied when the engine is turned off and the
vehicle is stationary.
It can only be disengaged when the engine is
restarted.
When the key is removed or set to STOP it
cannot be disengaged.
The electric parking brake can also be manually
engaged when the vehicle is moving or the key is
turned to MAR by pulling up the lever
B.
If the engine was turned off with the automatic
engagement device deactivated, you can
reactivated it simply by pulling lever B.
CAUTION
Always check that the vehicle is
actually locked before leaving it.
CAUTION
When the EPB button is
activated while driving, the vehicle
slows down with strong deceleration
(Dynamic Braking). It is therefore
advisable to use this function only
in case of an emergency. The vehicle
stability is in any case ensured by the
VDC system, which is always active.
Disengagement
The parking brake automatically disengages
when the accelerator pedal is depressed.
The electric parking brake can also be manually
disengaged when the vehicle is moving or the
key is in position MAR by manually pulling up
lever
B and simultaneously depressing the brake
pedal.
WARNING: In certain conditions it is however
advisable to manually disengage the electric
parking brake and brake the starting manoeuvre
slightly using the service brake. This is advisable
when there are obstacles very close to the
vehicle in the direction in which you intend to
move.

USING THE VEHICLE
Malfunction indication
In the event of electric parking brake system
failures, the warning light
! on the display
will come on.
Depending on the message displayed, it signals
the following failures of the EPB system:
- Parking brake failure
If the message warning you to go to the
nearest Authorised Service Centre of the
Manufacturer’s Network is displayed,
drive slowly and remember that the electric
parking brake device is not functioning.
- Excessive temperature. If after leaving the engine off (key turned
to STOP) for about 15 minutes without
using the parking brake, the warning
light illuminates again when the engine
is started, slowly drive to an Authorised
Service Centre of the Manufacturer’s
Network. If the brake failure is accompanied by the
message “Mechanical release only”, the
manual emergency deactivation procedure
must be performed to release the parking
brake.
Deactivating the PARK OFF automatic
operation
To deactivate manual operation of the electric
parking brake, with the engine on, press the
button
A on the dashboard. The words PARK OFF
will appear on the display for 5 seconds and then
the page that was active previously will reappear.
To reactivate automatic operation, press the
button A again, the words PARK ON appear on
the display for 5 seconds.
WARNING: In certain conditions, when the
battery voltage is low, the electric parking brake
activation/deactivation system may temporarily
be deactivated for safety reasons. Therefore,
typically during engine starting when the battery
voltage drops, the message PARK OFF may
temporarily appear on the display indicating that
automatic operation is temporarily disabled.
WARNING: In the case of performance
starting, check that the electric parking brake is
disengaged.
