2014 Alfa Romeo Giulietta check engine light

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.

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 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. In particular, the warning light on constantly
signals a malfunction in the injection/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, it is necessary to 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.

WARNING
68) Failure of the
warning light is indicated by the
warning light switching on. In addition, the airbag system
automatically disables the passenger side airbag. Before proceeding, contact an Alfa Romeo Dealership to have the
system checked immediately.
IMPORTANT
13) If, turning the ignition key to MAR-ON, the
warning light does not turn on or if it turns on steadily or flashing
when travelling (on certain versions together with the message on the display), contact an Alfa Romeo Dealership
as soon as possible.
IMPORTANT
14) The presence of water in the fuel supply system circuit may cause severe damage to the injection system and
irregular engine operation. If the
warning light comes on in the instrument panel (together with a message in the
display) contact an Alfa Romeo Dealership as soon as possible to bleed the system. If the above indications come
on immediately after refuelling, water has probably been poured into the tank: turn the engine off immediately and
contact an Alfa Romeo Dealership.

IMPORTANT
23) Keep your speed down when
snow chains are fitted; do not
exceed 50 km/h. Avoid potholes,
steps and pavements and avoid
driving for long distances on
roads not covered with snow to
prevent damaging the car and the
road surface.
STORING THE CARIf 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.
