2014 Alfa Romeo Giulietta check engine

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 the
warning 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 the
warning 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.

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.

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.

KNOWING THE INSTRUMENT PANEL

When the brake pedal is released, the
car will start with maximum
acceleration. Despite the "Sequential
mode", the car will autonomously shift
the gear to guarantee max.
acceleration, once the correct shifting
speed has been reached.
To abandon the strategy, simply
interrupt the above sequence
of operations or release the accelerator
pedal.
ACOUSTIC SIGNAL
For safety reasons, an acoustic signal is
heard when:
❒the driver's side door is opened with
engine running and the gear lever is
in a position other than P;
❒engine is switched off with gear lever
in a position other than P.
With the car stationary, the engine
started and (1st), (D) or (R) gear
engaged, the system activates the
acoustic signal and automatically
places the transmission in neutral (N)
when:
❒the accelerator and/or brake pedals
are not pressed for at least 3 minutes
with creeping deactivated (for
example with handbrake engaged);❒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.
163

If reverse (R) is engaged, only engage
the 1
stgear (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.
WARNING
106) Using the levers incorrectly
(levers pushed towards the
dashboard, see fig. 137) could
break them.
107) Never leave children
unattended in the car. Always
remove the ignition key when
leaving the car and take the key
with you.
SAVING FUELHere are some suggestions which can
help you to save fuel and lower harmful
emissions.
GENERAL
CONSIDERATIONS
Car maintenance
Checks and adjustments should be
carried out in accordance with the
“Scheduled Servicing Plan” (see
chapter “Maintenance and care”).
Tyres
Check the tyre pressures at least once
every four weeks: if the pressure is
too low, consumption levels increase as
resistance to rolling is higher.
Unnecessary loads
Do not travel with an overloaded boot.
The weight of the car and its
arrangement greatly affect fuel
consumption and stability.
164
STARTING AND DRIVING

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.
168
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.
