OBD port Alfa Romeo Giulietta 2013 Owner handbook (in English)

❒use of the car for short drives, in which the engine does not have
time to reach its regular operating temperature;
❒repeated interruption of the regeneration process, signalled by the
DPF warning light coming on.
If the warning light switches on, the deteriorated
engine oil must be changed as soon as possible, and
never more than 500 km from the first time that the
warning light switches on. Failure to observe the above may
result in severe damage to the engine and invalidate the
warranty. Remember that the operation of this warning light is
not related to the amount of oil in the engine. Therefore, never
top up with oil when the warning light starts flashing.Engine coolant overheating
(red)
Turning the key to the MAR position illuminates the warning light, but it
should switch off after a few seconds.
The warning light turns on when the engine is overheated.
The display will show the dedicated message.
If the warning light comes on when driving, proceed as follows:
❒normal driving conditions: stop the car, switch off the engine and
check that the water level in the reservoir is not below the MIN
mark. In this case, 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 reference
on the reservoir itself. Also check visually for any fluid leaks. If the
warning light comes on again at the next engine start-up, contact
Alfa Romeo Authorized Services.❒If the car is used under demanding conditions (e.g. towing trailers
uphill or fully loaded): slow down and, if the light stays on, stop
the car. Stand for 2 or 3 minutes with the engine running and
slightly accelerated to promote a better circulation of coolant. Then
stop the engine. Check the correct liquid level as described above.
IMPORTANT Under severe use of the car, it is advisable to keep the
engine on and slightly accelerated for a few minutes before switching it
off.
Doors not closed correctly
(red)(for versions/markets, where provided)
The warning light (or symbol on the display) lights up when one or
more doors or the tailgate are not closed correctly. 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 closed correctly.EOBD/injection system failure
(amber)
Under 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.

JUMP STARTINGWhen jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A fig. 91 of the car battery, but
rather to an engine/gearbox earth point.
Before opening the bonnet, make sure the engine is off and
the ignition key is in the STOP position. Follow the
instructions on the label on the front crossmember (fig. 92).
It is advisable to extract the key when there are other people in the
vehicle. Exit from the car only after having removed the ignition key or
having rotated it to the STOP position. During refuelling, make sure
that the engine is off and that the ignition key is in the STOP position.
EOBD SYSTEM (European On
Board Diagnosis)(for versions/markets, where provided)
The aim of the EOBD system (European On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace damaged components.
The car also has a diagnostic connector that can be interfaced with
appropriate tools, which makes it possible to read the error codes
stored in the electronic control units together with a series of specific
parameters for engine operation and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.
