DISPLAY
The car is equipped with a display that,
according to the previously applied
settings, will show useful driving
information.
GEAR SHIFT INDICATOR
The GSI (Gear Shift Indicator) system
advises the driver to change gear
through a specific indication 5 fig. 29, 30
on the instrument panel.
Through the GSI, the driver is notified
that the gear change will allow a
reduction in fuel consumption.
Therefore, for driving oriented towards
reducing fuel consumption, it is advisable
to stick to “Natural” or “All Weather”
mode and to follow the suggestions of
the Gear Shift Indicator, where traffic
conditions permit.
When the () icon is displayed on the
instrument panel, the GSI suggests
switching to a higher gear, while when
the () icon is displayed, the GSI
suggests shifting to a lower gear.
IMPORTANT The GSI is not active when
the transmission is operating in AUTO
mode.
The indication in the instrument panel
remains on until the driver shifts gear or
the driving conditions go back to a
situation where gearshifting is not
required to improve consumption.

new journey.
“Trip A” can be used to display the values
relating to:

WARNING LIGHTS AND MESSAGES
IMPORTANT The warning light switches on in the instrument panel together with a dedicated message and/or acoustic signal when
applicable. These indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to
the information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the information
in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults are
indicated by a repeated and prolonged warning “cycle”. Less serious faults are indicated by a warning “cycle” with a shorter duration.
The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause of the
malfunction is eliminated.

In this case release the accelerator pedal to lower the
engine speed until the warning light stops flashing.
Continue the journey at moderate speed, trying to avoid
driving conditions that may cause further flashing and
contact a dedicated Alfa Romeo Dealership as soon as

If the Uwarning light flashes, it means that the catalytic
converter may be damaged.
3)
Under these conditions, the vehicle can continue travelling
at moderate speed without demanding excessive effort
from the engine. Prolonged use of the car with the warning
light on constantly may cause damage.
Contact a dedicated Alfa Romeo Dealership as soon as
possible. INJECTION / EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR the Uwarning light switches on, but it should
switch off as soon as the engine is started.
The operation of the Uwarning light may be checked by
traffic police using appropriate equipment.

where you are driving.
If the Uwarning light stays on or switches on when
driving, it means that the injection system is not working
properly; in particular, if the warning light comes on
constantly, this indicates a malfunction in the
supply/ignition system that could cause excessive
exhaust emissions, a possible loss of performance, poor
driveability and high fuel consumption.
On some versions the display shows the dedicated
message.
The Uwarning light switches off if the malfunction
disappears, but is still stored by the system.
