Warning lights on
panelWhat it means What to do
redALTERNATOR FAILURE
The warning light switches on when the ignition
key is turned to MAR-ON, but it should switch off
as soon as the engine has started (with the
engine idling a brief delay before switching off is
acceptable).If the warning light (or symbol on the display)
stays on constantly or flashing, contact an Alfa
Romeo Dealership as soon as possible.
WARNING
63) If thewarning light does not switch on when the key is turned to MAR-ON or if it stays on when driving (together
with the message on the display), there may be a fault in the restraint systems; in this case, the airbags or
pretensioners may not deploy in the event of an accident or, in a lower number of cases, they could deploy
erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.
64) Failure of the
warning light is signalled by the flashing for longer than the usual 4 seconds of thewarning light
(located in the trim above the internal rear view mirror). In addition, the airbag system automatically disables the
passenger side airbag. In this case, the
warning light may not indicate a fault in the restraint systems. Before
proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.

Warning lights on
panelWhat it means What to do
redENGINE COOLANT TEMPERATURE TOO
HIGH
When the key is turned to MAR-ON, the warning
light switches on but should switch off after a few
seconds. The warning light turns on when the
engine is overheated.
The display shows the dedicated message.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, wait
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 on the reservoir. Also check visually for any
fluid leaks. Should the warning light turn on again
at the next start-up, contact an Alfa Romeo
Dealership.
If the car is used under demanding conditions
(e.g. in high-performance driving): slow down
and, if the warning light stays on, stop the car.
Wait for 2 or 3 minutes with the engine running
and slightly accelerated to further favour the
coolant circulation. Then stop the engine. Check
the correct coolant level as described above.
IMPORTANT Over demanding routes, it is
advisable to keep the engine on and slightly
accelerated for a few minutes before switching it
off.
105

Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR-ON the warning light switches on, but it should
switch off as soon as the engine is started. The operation
of
warning light may be checked by the traffic police
using specific devices. Comply with the laws and
regulations of the country where you are driving.
13)
If the warning light remains on or switches on whilst
driving, it means that the injection system is not working
properly. The warning light on constantly signals a
malfunction in the supply/ignition system which could
cause high exhaust emissions, a possible loss of
performance, poor driveability and high consumption.
On some versions, the display shows the dedicated
message. The warning light goes out after the fault
disappears: the indication is stored in the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the car with the
warning light on constantly may cause
damage.
Contact an Alfa Romeo Dealership as
soon as possible.
Petrol engines only
If the warning light flashes, it means that the catalytic
converter may be damaged.In this case, release the accelerator pedal
to lower the speed of the engine until the
warning light stops flashing. Continue the
journey at moderate speed, trying to avoid
driving conditions that may cause further
flashing and contact an Alfa Romeo
Dealership as soon as possible.

HEATING FAILURE (diesel versions)
This warning light switches on when the key is
turned to MAR-ON. It will switch off as soon as
the heater plugs have reached a preset
temperature. The engine can be started as soon
as the warning light switches off.
IMPORTANT In mild or high temperature
conditions, the warning light comes on for a very
short time only.
Glow plug preheating failure
The warning light will flash (a message will appear
on the display, on some versions) to indicate a
fault in the glow plugs preheating system.Contact an Alfa Romeo Dealership as soon as
possible.
amberWATER IN DIESEL FILTER (diesel versions)
The warning light remains on constantly when
driving (together with a message in the display),
to indicate the presence of water in the diesel
filter.

KNOWING THE INSTRUMENT PANEL

❒the brake pedal is pressed for longer
than 10 minutes;
❒the driver's door is opened with
creeping deactivated (for example
with handbrake engaged) without
pressing brake and/or accelerator
pedals;
❒a fault has been detected in the
transmission.
IMPORTANT Shifting to neutral (N) -
operated by the system - involves
a situation of inconsistency between
gear lever position and gear engaged.
The manoeuvre is accompanied by
an acoustic inconsistency signal. This
acoustic signal continues until the gear
lever is placed in P or N, to restore
the correct transmission operation
conditions.
PARKING THE CAR
To park safely, with the brake pedal
pressed, P must be engaged and, in
case of parking uphills/downhills, the
handbrake must be engaged.
Before releasing the brake pedal, wait
until P appears on the display.
IMPORTANT NEVER leave the car
before having positioned the lever in P.TOWING THE CAR
Make sure that the transmission is in
neutral (N), checking that the car moves
when pushed, and proceed in the
same way as for towing a normal car
with a manual gearbox.
IMPORTANT If the transmission cannot
be put in neutral (N), do not tow the
car and contact an Alfa Romeo
Dealership. Should the lever be in P,
release it before towing (see paragraph
"Positions of the lever").
IMPORTANT
INFORMATION
With car stationary and gear engaged,
always keep the brake pedal pressed
until you decide to set off, then release
the brake and accelerate gradually.
During prolonged stops with the engine
running, it is advisable to keep the
transmission in neutral (N).
To protect the clutch, never use the
accelerator to keep the car stationary
(for example when stopped uphills/
downhills): clutch overheating could
damage it. Use the brake pedal instead
or the handbrake and only press the
accelerator pedal when you wish to set
off.If reverse (R) is engaged, only engage
the 1stgear (or vice versa) when the car
is completely stopped.
Although it is highly inadvisable, if you
are driving downhill and, for unexpected
reasons, you let the car move forward
with the transmission in neutral (N),
when there is a request to engage
a gear, depending on the speed of the
car, the system will automatically
engage the best gear for the correct
transmission of drive torque to the
wheels.
107)
IMPORTANT
21) If the car is on a gradient, always
pull the handbrake BEFORE
placing the gear lever in P.
22) Engage reverse only with the car
stationary, engine at idling speed
and accelerator fully released.

STORING THE CAR
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒park the car in covered, dry and if
possible well-ventilated premises and
slightly open the windows;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal and check the battery
charge. Repeat this check once
every three months during storage;
❒if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds
available commercially;
❒sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glasses;
❒slightly open the windows;❒cover the car with a cloth or
perforated plastic sheet. Do not use
compact plastic sheets which do
not allow humidity to evaporate from
the surface of the car.
❒inflate tyres to +0.5 bar above the
standard prescribed pressure and
check it periodically;
❒do not drain the engine cooling
system;
❒Any time the car is left inactive for
two weeks or more, operate the
air conditioning system with engine
idling for at least 5 minutes, setting
external air and with fan at maximum
speed. This operation will ensure a
suitable lubrication to minimise
possibility of damage to the
compressor when the system is
operated again.
IMPORTANT After turning the ignition
key to STOP, wait at least 1 minute
before disconnecting the electrical
supply to the battery.
162
STARTING AND DRIVING

❒inflate the tyre to the pressure
indicated in the “Wheels” paragraph
in the “Technical data” chapter. In
order to obtain a more precise
reading, check the pressure value on
pressure gauge B fig. 153 with the
compressor off;
❒if after five minutes it is still impossible
to reach at least 1.8 bar, disengage
the compressor from the valve and
power socket, then move the car
forwards by approx. ten metres
in order to distribute the sealing fluid
inside the tyre evenly, then repeat
the inflation operation;
❒if you still cannot obtain a pressure of
at least 1.8 bar within 5 minutes from
the compressor switching on, do
not drive off and contact an Alfa
Romeo Dealership;❒after having driven for about 10
minutes, stop and recheck the tyre
pressure; remember to engage
the handbrake;
❒if a pressure value of at least 1.8 bar
is detected, restore the correct
pressure (with the engine running and
the handbrake engaged), resume
driving and drive with great care to an
Alfa Romeo Dealership.
CHECKING AND
RESTORING TYRE
PRESSURE
The compressor can also be used to
check and, if necessary, adjust the tyre
pressure.
Release quick coupling A fig. 157 and
connect it directly to the valve of the
tyre to be inflated.
