2007 Alfa Romeo GT check engine light

CORRECT USE OF THE CAR
172
Never leave children un-
attended in the car. Al-
ways remove the ignition
key when leaving the car and take
it with you.To avoid useless con-
sumption of power and
possible draining of the
battery, never leave the ignition
key in the MAR position when the
engine is not running.
PARKING
When the car is parked, proceed as fol-
lows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the car is faced up-
hill or reverse if the car is facing downhill.
– Turn the front wheels so that the car will
immediately come to a halt if the handbrake
slips.
REDUCING
RUNNING COSTS
AND ENVIRONMENT
POLLUTION
By following a few simple guidelines, it
is possible to save car running costs and re-
duce harmful emissions.
GENERAL CONSIDERATIONS
Car maintenance
To take care of the car maintenance have
the checks and adjustments carried out in
accordance with the “Scheduled Mainte-
nance Programme”.
Tyres
Check the pressure of the tyres routinely
at an interval of no more than 4 weeks: if
the pressure is too low consumption levels
increase as resistance to rolling is higher.
Useless loads
Never travel with an overload in the boot.
The weight of the car (especially in urban
traffic), and its geometry heavily affect con-
sumption levels and stability.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy,
therefore increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels(up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.

CORRECT USE OF THE CAR
178
Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements and
avoid also to drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
CAR INACTIVITY
If the car is to be left inactive for long pe-
riods, the following precautions should be
noted:
– House the car under cover in a dry and
possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not en-
gaged.
– Clean and protect the paintwork by pro-
tective wax.
– Clean and protect the metal polished
parts with marketed products.
– Cover the rubber windscreen and
rearscreen wiper blades with talcum powder
and raise them off the glass.
– Open the windows slightly.
– Inflate the tyres to a pressure of 0.5 bars
above normal. If possible rest the tyres on
wooden planks and periodically check the
pressure.
– Do not turn on the electronic alarm sys-
tem.– Disconnect the battery negative termi-
nal from the battery and check the battery
charge. This check should be repeated
every three months during stowage.
Charge the battery if the indicator (where
provided) shows a dark colour in the central
green area.
– Do not empty the engine cooling sys-
tem.
– Cover the car with a fabric or perforat-
ed plastic cover. Do not use compact plas-
tic covers which prevent the humidity on the
surface of the car from evaporating. Snow chains cannot be
fitted to the space-saver
spare wheel. So, if a front
(drive) wheel is punctured and
chains are needed, a rear wheel
should be fitted to the front of the
car (adjust tyre pressure to the
specified value as soon as possi-
ble) and the space-saver spare
wheel should be fitted to the rear.
This way with two normal drive
wheels, snow chains can be fitted
to them to solve an emergency.
Deactivate the ASR sys-
tem when snow chains are
fitted. Press the ASR-OFF
button, button led turned on.

IN AN EMERGENCY

– make sure the compressor switch A-
fig. 16is set to 0(off), start the engine
and fit plug A-fig. 17into the cigar lighter
outlet and then turn on the compressor by
setting switch A-fig. 16toI(on);
fig. 16
A0A1100b
– inflate the tyre to the correct pressure
value. Check tyre pressure on gauge B-fig.
16with compressor off to obtain precise
reading;
– if after 5 minutes it is still impossible
to reach at least 1.5 bar, disengage com-
pressor from valve and current outlet, then
move the car forth for approx. ten metres in
order to distribute the sealing fluid inside the
tyre evenly, then repeat the inflation oper-
ation;– if after this operation it is still impossi-
ble after 5 minutes to reach at least 1.8 bar,
do not start driving since the tyre is exces-
sively damaged and the quick tyre repair kit
cannot guarantee suitable sealing, contact
Alfa Romeo Authorized Services;
– once the correct tyre pressure has been
reached, start driving immediately;
fig. 17
A0A0647b
Apply the sticker in a vis-
ible position for the driver
to indicate that the tyre
has been treated with the quick
tyre repair kit. Drive carefully es-
pecially when cornering. Do not ex-
ceed 80 km/h. Avoid heavy brak-
ing and accelerating.

– Fit a new bulb, making the tab of the
metal part coincide with the one on the lamp
unit, then hook the bulb holder catch (B).
– Re-connect the electric connector (A).
– Refit the protective cover correctly.Fog lights(fig. 24)
IMPORTANTWhen needing to change
the left bulb, the side trim next to the light
itself needs to be removed to facilitate ac-
cess to the engine compartment.
To change the bulb, proceed as follows:
– Remove the protective cover turning
counter-clockwise.
– Disconnect the electric connector (A).
– Release the bulb catch (B).
– Remove the bulb and replace it.
fig. 24
A0A0161b
After replacement, refit
the covers correctly check-
ing that they are properly
secured.
IMPORTANTA slight layer of steam
(fogging) can appear on the inside surface
of the beam transparent cover: this is not
a defect. The presence of condensate traces
in beams is a natural phenomenon, due to
a low temperature and to the degree of hu-
midity in the air. These traces will disappear
when the beams are turned on. Drops of wa-
ter inside the headlight indicate instead wa-
ter infiltration: contact Alfa Romeo Autho-
rised Services.

CHECKING LEVELS
Never smoke while work-
ing in the engine compart-
ment; gas and inflammable
vapours may be present, with the
risk of fire.
When topping up take
care not to confuse the var-
ious types of fluids: they
are incompatible with one anoth-
er and could seriously damage the
car.
