Hot engine coolant (red)
When the ignition key is turned to MAR, the warning
light turns on but should go off after a few seconds.
The warning light turns on when the engine is over-
heated. A specific message will be shown on the display.
If the warning light comes on, proceed as follows:
❍when driving normally: stop the car, switch off the engine and
check that the water level in the reservoir is not below the MIN
mark. If it is not, wait for a few minutes for the engine to cool
down then slowly and carefully open the cap, top-up with coolant
and check that the level is between the MIN and MAX marks.
Also visually check for leaks. If the warning light comes on again
at the next engine start-up, contact Alfa Romeo Authorized Ser-
vices.
❍if the car is used under demanding conditions (e.g. towing trail-
ers uphill or fully loaded): slow down and, if the light stays on,
stop the car. Stop for two or three minutes with the engine run-
ning and slightly accelerated to assist better coolant circulation.
Then switch the engine off. Check correct fluid level as described
above.
IMPORTANT On particularly demanding journeys, it is advisable to
keep the engine on and slightly accelerated for a few minutes be-
fore switching it off.
u
Door open (red)
(for versions/markets, where provided)
The warning light (or symbol on the display) comes
on when one or more doors or the boot are not perfectly
closed. An acoustic signal is activated with the doors open and
the car moving. On some versions, the warning light (or symbol
on the display) also lights up when the bonnet is not perfectly
closed.´
EOBD/injection system fault (amber)
Under normal conditions, the warning light comes on
when the ignition key is turned to MAR, but should
go off as soon as the engine is started.
If the warning light remains on or comes on whilst driving, that
means that the injection system is not working properly; in partic-
ular, if the warning light comes on constantly, this indicates a mal-
function in the supply/ignition system that could cause excessive
exhaust emissions, a possible loss of performance, poor driveabil-
ity and high fuel consumption.
A specific message is displayed on certain versions.
Under these conditions, you can continue travelling at moderate
speed without demanding excessive effort from the engine. Pro-
longed use of the car with the warning light on may cause dam-
age. Contact Alfa Romeo Authorized Services as soon as possible.
The warning light goes out after the fault disappears, but the in-
dication is stored in the system.U

GEAR SHIFT INDICATOR
The GSI system (Gear Shift Indicator) suggests to shift gear by
showing an indication on the control panel (see fig. 9).
Shifting when indicated by GSI will help the driver save fuel.
For fuel-effective driving, select Normal or All Weather mode and
follow the suggestions of the Gear Shift Indicator where possible.When the SHIFT UP icon (
NSHIFT) appears on the display, the
GSI is suggesting to select a higher gear and when the SHIFT DOWN
(
OSHIFT) icon it is suggesting that a lower gear should be se-
lected.
NOTE The indication on the instrument panel stays on until the
driver shifts or until the driving conditions return to a situation in
which shifting is not required to reduce consumption.

OPERATING MODES
Engine stopping mode
With the car at a standstill, the engine stops with the gearbox in
neutral and the clutch released.
NOTEThe engine can only be stopped automatically after a speed
of about 10 km/h is reached, to prevent the engine from being
repeatedly stopped when driving at walking pace.
Symbol
Ufig. 81 appears on the display when the engine stops.
Engine restarting mode
Press the clutch pedal to restart the engine.

START&STOP SYSTEM
(for versions/markets, where provided)
The Start&Stop system automatically stops the engine whenever
the car is stationary and starts it again when the driver wants to
move off. This improves the efficiency of the vehicle by reducing
fuel consumption, the emission of harmful gases and noise pollu-
tion.
The system is active every time the engine is started.

SAVING FUEL
Here are some suggestions which may help you to save fuel and
lower the amount of harmful emissions released into the atmos-
phere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out in accordance with the
“Scheduled Servicing Plan” (see chapter “Servicing and mainte-
nance”).
Tyres
Check the tyre pressure at least once every 4 weeks: if the pres-
sure is too low, consumption levels increase as resistance to rolling
is higher.
Unnecessar y loads
Do not travel with an overloaded boot. The weight of the car and
its arrangement 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 and have a nega-
tive effect on fuel consumption. It is better to use a trailer to trans-
port particularly bulky objects.
Electric devices
Use electric devices only for the amount of time needed. The heat-
ed rear windscreen, additional headlights, windscreen wipers and
heater fan require a considerable amount of energy; increasing the
current uptake increases fuel consumption (by up to +25% in an
urban cycle).
Climate control system
Using the climate control system will increase consumption: use
the air vents when the external temperature so allows.
Spoilers
The use of non-certified spoilers may adversely affect aerodynam-
ics and fuel consumption.

DRIVING STYLE
Starting
Do not warm up the engine at low or high revs when the car is
stationary; this causes the engine to warm up more slowly, there-
by increasing fuel consumption and emissions. It is advisable to set
off immediately and slowly, avoiding high revs: this allows the
engine to warm up more quickly.
Unnecessar y actions
Avoid revving up when starting at traffic lights or before stopping
the engine. The latter action, like double-declutching, is unneces-
sary and causes increased fuel consumption and pollution.
Gear selection
Use a high gear when traffic and road conditions allow. Using a
low gear for faster acceleration will increase fuel consumption. In
the same way, improper use of a high gear increases fuel con-
sumption, emissions and engine wear.
Top speed
Fuel consumption considerably increases as speed increases. Keep
your speed as even as possible, avoiding unnecessary braking
and acceleration which cause excessive fuel consumption and in-
creased emissions.
Acceleration
Accelerating violently severely affects consumption and emissions:
acceleration should be gradual and should not exceed the maxi-
mum torque.
CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups prevent the engine from
reaching its optimum running temperature. Consequently, both con-
sumption (from +15 to +30% on the urban cycle) and emissions
will increase.
Traffic and road conditions
High fuel consumption is caused by heavy traffic, for instance when
travelling in a queue with frequent use of low gears or in cities with
many traffic lights. Mountain roads and uneven surfaces also have
a negative effect on consumption.
Traffic hold-ups
During prolonged hold-ups (level crossings) the engine should be
switched off.

FUEL CONSUMPTION
The fuel consumption figures given in the table below are deter-
mined on the basis of the homologation tests laid down by specific
European Directives.
The procedures below are followed for measuring consumption:
❍urban cycle: cold starting followed by driving that simulates
urban use of the car;
❍extra urban cycle: driving simulating the use of the vehicle in
a non-urban situation with frequent acceleration in all gears;
the speed varies between 0 and 120 km/h;
❍combined consumption: about 37% of the urban cycle and
around 63% of the non-urban cycle.IMPORTANT The type of route, traffic situations, weather conditions,
driving style, general conditions of the car, trim level/
equipment/accessories, load, climate control system, roof rack,
other situations that affect air drag may lead to different fuel con-
sumption levels than those measured.
