MUST BE READ!REFUELLING
Petrol engines:only refuel with unleaded petrol with octane rating (RON) no less than 95.
Diesel engines:only refuel with diesel fuel conforming to the European specification EN590.
K
ENGINE START-UP
Petrol engines with mechanical transmission:make sure the handbrake is pulled; put the gear lever into neutral;
press the clutch pedal down to the floor without touching the accelerator, then turn the ignition key to AV Vand release it as
soon as the engine starts.
Petrol engines with Selespeed transmission or Q-System:keep the brake pedal fully depressed; turn the igni-
tion key to AV Vand release it as soon as the engine has started; the transmission sets to neutral automatically (the display
shows position N).
Diesel engines:Turn the ignition key to MARand wait for the
Y
and
m
warning lights to go off; turn the ignition
key to AV Vand release it as soon as the engine starts.
PARKING OVER FLAMMABLE MATERIAL
While functioning normally, the catalytic converter reaches high temperatures. For this reason do not park the car over in-
flammable material, grass, dry leaves, pine needles, etc.: fire hazard.

STOPPING THE CARTo stop the vehicle, simply release the ac-
celerator pedal and, if necessary, operate
the brake pedal.
Regardless of the gear engaged and of the
operating mode activated (MANUALor
CITY), the system automatically disen-
gages the clutch and downshifts gear.
If you intend to move off again without
having completely stopped the car, this way
the most suitable gear ratio for re-acceler-
ating will be available.
Stopping the vehicle, the system auto-
matically engages first gear (1). Though strongly inadvisable, if due to un-
foreseen circumstances when driving down-
hill the car is allowed to travel with the gear-
box in neutral (N), when the engagement
of a gear is requested, the system auto-
matically engages the best gear to allow
transmission of the torque to the wheels in
relation to the speed of the car.
Downhill with the gear engaged and the
accelerator released (if the vehicle is trav-
elling), if a certain pre-established speed is
exceeded, the system automatically en-
gages the clutch to provide adequate engine
braking.
Due to safety reasons, the Selespeed sys-
tem activates the buzzer when:
– clutch overheating occurs during vehicle
starting; in this case, it is necessary to
“force” moving off avoiding hesitations or
to release the accelerator and use the brake
pedal to park the vehicle if the car is on a
slope;
– the car moves in the opposite direction
to the gear engaged, (e.g.: vehicle moving
forward with reverse engaged); in this sit-
uation it is necessary to stop the vehicle and
keeping the brake pedal pressed, engage
the gear correctly.Still for safety reasons, when the vehicle
is stationary, with the engine started and
gear (1), (2) or (R) engaged, the system
activates the buzzer and shifts to neutral
(N) automatically when:
– there is no action on the accelerator
and/or brake pedal for at least 3 minutes;
– the brake pedal is pressed for over 10
minutes;
– the driver’s door is opened and the ac-
celerator and brake pedal are not pressed
for at least 1 second.

AUTOMATIC OPERATION (CITY)The CITYautomatic operating mode is se-
lected pressing the button (A-fig. 132),
at the base of the gearshift lever.
In addition to the gear, the display on the
rev counter will show the word CITY.
The system decides directly when gearshift-
ing according to the engine running speed
and the driving style.
Quickly releasing the accelerator pedal, the
system does not engage a higher gear in or-
der to maintain an adequate level of engine
brake.
FAILURE SIGNALLINGFailures to the Selespeed gearbox are in-
dicated by the
t
(A-fig. 133) warn-
ing light on the instrument cluster.
When the system is turned on (turning the
ignition key to MAR), the warning light
should turn on glowing steadily for about
4 seconds and then turn off.
If the warning light stays on it means that
a fault to the gearbox has been detected; at
the same time a buzzer sounds intermit-
tently for 4 seconds to attract the driver's
attention.In the case of a fault to the gearshift lever,
the system automatically activates the au-
tomatic CITYmode to allow the car to
reach the nearest Authorized Alfa Romeo
Services to have the fault detected elimi-
nated.
In the event of faults to other components
of the gearbox, the system only allows the
engagement of certain ratios: first gear (1),
second (2) and reverse (R).

If the warning light

comes on, contact the Alfa
Romeo Authorized Services
as soon as possible to remove the
fault.In case of transmission
fault, contact the Alfa
Romeo Authorized Services as
soon as possible to check the sys-
tem.

RADIO
TRANSMITTERS
AND CELLPHONESCellphones and other radio transmitters
(e.g. CB radios) cannot be used inside the
vehicle, unless you use a separate aerial
mounted outside the vehicle.
The transmission and reception efficiency
of this equipment may also be affected by
the shielding effect of the vehicle’s body.
SUNROOF(optional for versions/markets
where applicable)
The sunroof can only be operated when
the ignition key is in the MARposition.Do not open the sunroof
when snow or ice are on
the roof as this may dam-
age it.
The use of cellphones, CB
radios or similar inside the
passenger compartment (without
an outside aerial) produces electro-
magnetic RF fields; if these are am-
plified by the resonance inside the
passenger compartment, they may
not only result in a potential health
hazard, or poor functioning of the
electronic systems such as engine
control units, ABS/EBD control
units, etc., fitted to the vehicle, but
also put the safety of your vehicle
in jeopardy.
WARNING
Improper use of the sunroof
can be dangerous. Before
and while operating it, always
make sure that the passengers are
not exposed to the risk of harm
caused either directly by the sunroof
in motion or by personal items
drawn or knocked by it.
WARNING
When leaving the vehicle,
the ignition key should al-
ways be removed to avoid acci-
dents involving the sunroof which
could be inadvertently operated by
any passenger remaining in the ve-
hicle.

ADDITIONAL
OPERATIONSEvery 1000 kmor before long journeys
check and if necessary top up:
– engine coolant level
– brake fluid/hydraulic clutch control flu-
id level
– power steering fluid level
– windscreen washer and headlamp wash-
er fluid level
– tyre pressure and conditions.
Every 3000 kmcheck the level of the
engine oil and top up if necessary.
You are recommended to use products of
the FL Selenia, designed and developed
expressly for Alfa Romeo cars (see the table
“Specifications of fluids and lubricants” in
the “Technical specifications” chapter).
ANNUAL INSPECTION
PROGRAMMEAn annual inspection programme
has been established for cars thet
cover less than 20,000 km (e.g.
10,000 km). It consists of the fol-
lowing:
– Check tyre conditions/wear and adjust
pressure if required (including the compact
spare wheel)
– Check lighting system operation (head-
lights, direction indicators, hazard lights,
boot lights, passenger compartment lights,
glovebox light, warning lights of instrument
panel, etc.)
– Check windscreen and rear-screen
wiper/washer operation, adjust nozzles
– Check windscreen/rear-screen blade po-
sition/wear
– Check condition and wear of the front
brake pad
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication– Visually check the following: engine,
gearbox, transmission, piping (exhaust - fu-
el - brakes) rubber components (casings -
sleeves - bushings, etc..), brake and fuel
hoses
– Check battery charge condition
– Visually check the condition of the belts
and various controls
– Check and top up if necessary, the flu-
id levels (coolant, brake fluid, windscreen
washer fluid, battery, etc.)
– Change engine oil
– Replace engine oil filter
– Change pollen filter.
