Insufficient tyre inflation pressure
(where provided)
This warning light (or symbol in the display) comes on
(on some versions together with a message on the dis-
play) (together with the sounding of a buzzer) if the tyre infla-
tion pressure of one or more tyres goes below a preset value. In
this way the T.P.M.S. system warns the driver that one or more
tyres may be dangerously flat and liable to puncture.
IMPORTANT Do not continue driving with one or more tyres flat
as vehicle driveability may be compromised. Stop the car, avoid-
ing harsh braking or steering manoeuvres. Replace the wheel im-
mediately with the spare wheel (where provided) or carry out a
repair using the dedicated kit (see the paragraph on “Replacing
a wheel” in chapter 4) and contact an Alfa Romeo Authorised Ser-
vice as soon as possible.n
T.P.M.S. system failure
(where provided) (amber)
This warning light (or symbol in the display) comes on (on some
versions together with a message in the display) when a fault is
detected in the T.P.M.S tyre inflation pressure monitoring system:
if this occurs, contact your nearest Alfa Romeo Authorised Service
as soon as possible.
Should one or more wheels be fitted without sensors, the display
will show a warning message until initial conditions are restored.
Check tyre inflation pressure
(where provided)
If this warning light (or symbol in the display) comes on (on some
versions together with a message in the display) this indicates that
the tyre pressure is below the optimum value recommended to
guarantee long tyre life and low fuel consumption. It may also in-
dicate a slow loss of pressure.
Should two or more tyres be discovered to be in the above men-
tioned condition, the display will show the indications corresponding
to each tyre in sequence. Under these circumstances you should
restore the correct pressure values (see chapter 6).

Values displayed
Range
Approximately indicates the distance the vehicle can travel with
the present amount of fuel in the tank.
The message “- - - -” will appear on the display in the following
cases:
– range value lower than 50 km (or 30 mi)
– car left parked with the engine running for a long time.
IMPORTANT Changes in the range value can be affected by many
factors: driving style, type of route (motorway, urban road, moun-
tain road, etc.), vehicle use conditions (load being carried, tyre
inflation pressure, etc.). The above notes should therefore be tak-
en into consideration when planning a trip.
Distance travelled
This value shows the distance covered from the start of the new
mission.
Average fuel consumption
This value shows the approximate average fuel consumption from
the start of the new mission.
Instantaneous fuel consumption
This indicates any change in fuel consumption. The value is con-
stantly updated. The message “- - - -” will appear on the display
if the car is parked with the engine running.
Average speed
This value shows the average speed of the car based on the overall
time elapsed since the start of the new mission.
Trip time
This value shows the time elapsed since the start of the new mis-
sion.

FUEL FILLER CAP
Opening
1) Open the flap A-fig. 74 pulling it outwards, keep the cap B
still, insert the ignition key in the lock and turn it anti-clockwise.
2) Turn the cap anti-clockwise and extract it. The cap has a de-
vice C retaining it to the flap so it cannot be lost. When refilling,
attach the cap to the flap D.
Closing
1) Fit the cap (complete with key) and turn it clockwise until it
clicks once or more.
2) Turn the key clockwise and extract it, then close the flap.
The hermetic seal may cause a slight increase in pressure in the
tank. A suction noise when you release the cap is therefore entirely
normal.
Keep naked flames or lighted cigarettes away from
the fuel filler hole as there is a danger of fire. Do
not bend too close to the hole either so as not to
breathe in harmful vapours.

154STARTING UP AND DRIVING
SAVING FUEL
Here are some suggestions which may help you to save fuel and
lower the amount of toxic emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out in accordance with the
“Scheduled servicing plan”.
Tyres
Check tyre pressure regularly, at least once every four weeks: ex-
cessively low pressure will increase fuel consumption because rolling
resistance will be higher.
Unnecessar y loads
Do not travel with an overloaded boot. The weight of the car and
its ride setting greatly affect fuel consumption and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack from the roof after use. These
accessories decrease aerodynamic penetration of the car and have
a negative effect on fuel consumption. It is better to use a trailer,
particularly for transporting bulky objects.
Press the clutch pedal fully to change gears cor-
rectly. For this reason, there must be no obstacles
on the floor under the pedals: ensure that any rub-
ber mats are correctly positioned, and do not interfere
with the pedals
Do not drive with your hand resting on the gear
lever, because this pressure, even if light, can wear
out the gearbox internal components over time.

PERIODIC CHECKS
Every 1,000 km or before long journeys, check and top up the fol-
lowing if necessary:
❍engine coolant level, brake fluid and windscreen washer fluid
❍tyre pressure and condition;
❍operation of lights (headlights, direction indicators, hazard
lights, etc.);
❍operation of the windscreen wiper/washer system, position
and wear of windscreen/rearscreen wiper blades;
Every 3,000 km check the following and top-up, if necessary: en-
gine oil level.
We recommend the use of FL Selenia products, designed and pro-
duced specifically for Alfa Romeo cars (see “Consumables” table
in chapter 6).
DEMANDING USE OF THE CAR
If you use the vehicle mainly under one of the following conditions:
❍trailer or caravan towing;
❍dusty roads;
❍repeated short distances (less than 7-8 km) and with exter-
nal temperatures below zero;
❍frequently idling the engine, travelling long distances at low
speeds or long term inactivity;
❍in cities;
perform the following inspections more frequently than shown on
the Scheduled Servicing Plan:
❍check front disc brake pad condition and wear;
❍check cleanliness of bonnet and boot locks, and cleanliness and
lubrication of linkages;
❍visually inspect the condition of: engine, gearbox, transmission,
pipes and hoses (exhaust – fuel supply - brakes) rubber ele-
ments (gaiters – hoses - bushes etc.);
