2006 Alfa Romeo GT check engine

Never push, tow or
coast start the vehicle.
This could cause fuel to
flow into the catalyst damaging
it irreversibly.
Remember that the
engine brake and power
steering are not opera-
tional until the engine is started,
therefore, much greater effort
than usual is needed on the brake
pedal and steering wheel.CORRECT USE OF THE CAR
202
For cars with tur-
bocharger in particular,
but for all cars in general,
sharp accelerating should be
avoided before switching the
engine off.
A “kick” on the accelerator
serves no purpose, consumes fuel
pointlessly and may cause seri-
ous damage to the turbocharger
impeller bearings.EMERGENCY STARTING
If the Alfa Romeo CODE system does not
recognise the code transmitted by the igni-
tion key (warning light
Yon the instru-
ment cluster glowing on steadily) emer-
gency starting may be carried out using
the code of the CODE card.
For the correct procedure see the chapter
“In an emergency”.
IMPORTANTIf the engine turns off
with the vehicle on the move, the next
time it is started, the Alfa Romeo CODE
warning light may turn on(
Y). In this
case, check that switching off and starting
the engine again with the vehicle station-
ary, the warning light stays off. If not, con-
tact Alfa Romeo Authorised Services.
ENGINE SWITCHING OFF
– Release the accelerator pedal and wait
until the engine reaches idle speed.
– Turn the ignition key to the STOP
position and switch off the engine.
IMPORTANTAfter a tiring journey it is
advisable to let the engine “get its breath
back” allowing it to idle a while to lower
the temperature in the engine compart-
ment.

Never leave children
unattended in the vehicle.
Always remove the igni-
tion key when leaving the vehicle
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.
CORRECT USE OF THE CAR
203
PARKING
When the vehicle is parked, proceed as
follows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the vehicle is faced
uphill or reverse if the vehicle is facing
downhill.
– Turn the front wheels so that the vehi-
cle 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 vehicle running costs
and reduce harmful emissions.
GENERAL CONSIDERATIONS
Vehicle maintenance
To take care of the car maintenance
have the checks and adjustments carried
out in accordance with the “Scheduled
Maintenance 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 vehicle (especial-
ly in urban traffic), and its geometry heav-
ily affect consumption levels and stability.Electric services
Use electric devices only for the amount
of time needed. Rearscreen heating, addi-
tional headlights, windscreen wipers and
heater fan need a considerable amount of
energy, therefore increasing the require-
ment of current increases fuel consump-
tion (up to +25% in the urban cycle).
Climate control system
The climate control system is a further
load bearing heavily on the engine induc-
ing higher consumption levels(up to
+20% on average). Outside temperature
permitting, preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.

CORRECT USE OF THE CAR
209
Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements to
prevent damaging the tyres, sus-
pension and steering. Remember
that with snow chains fitted the
brake distance will increase.
VEHICLE INACTIVITY
If the vehicle is to be left inactive for
long periods, the following precautions
should be noted:
– House the vehicle under cover in a dry
and possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not
engaged.
– Clean and protect the paintwork by
protective wax.
– Cover the rubber windscreen and
rearscreen wiper blades with talcum pow-
der 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
system.– Disconnect the battery negative termi-
nal (–) from the battery and check the
battery charge. This check should be
repeated once a month during stowage.
Charge the battery if the loadless voltage
is below 12,5V.
– Do not empty the engine cooling sys-
tem.
– Cover the vehicle with a fabric or per-
forated plastic cover. Do not use compact
plastic covers which prevent the humidity
on the surface of the vehicle from evapo-
rating. Snow chains cannot be
fitted to the compact
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 vehicle (inflate the tyres to
the specified pressure as soon as
possible) and the 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.
With snow chains fitted
it is advisable to turn off
the ASR system. Press
the ASR-OFF button, led on but-
ton on.

– make sure the compressor switchA-
fig. 16is set to 0 (off), start the engine
and fit plugA-fig. 17into the outlet/cig-
ar lighter on the front console and then turn
on the compressor by setting switch A-fig.
16toI(on);– inflate the tyre to the proper 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. 10 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 start driving since the tyre is excessive-
ly damaged and the quick tyre repair kit can-
not guarantee suitable sealing, contact Al-
fa Romeo Authorized Services;
– after reaching the proper tyre pressure,
start driving immediately;
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 and do not
exceed 80 km/h. Avoid heavy
braking and accelerating.

– after driving for about 10 minutes stop
and check again the tyre pressure; pull up
the handbrake;
If pressure falls below
1.8 bar, stop the car since
the tyre is excessively
damaged and the quick tyre repair
kit Fix & Go automatic cannot
guarantee suitable sealing, contact
Alfa Romeo Authorized Services.
– if at least 1.8 bar pressure is read, re-
store proper pressure (with engine running
and handbrake on) and restart;
– drive with the utmost care to the near-
est Alfa Romeo Authorized Service.You shall absolutely com-
municate that the tyre has
been repaired with the
quick tyre repair kit. Hand the in-
struction brochure to the personnel
charged with treating the tyre re-
paired with the kit.CHECKING AND RESTORING
PRESSURE ONLY
The compressor can be also used just for
restoring pressure. Disconnect the quick con-
nectionA-fig. 18and connect it directly
to the tyre valve fig. 19; in this way the
cylinder is not connected to compressor and
the sealing fluid will not flow into the tyre.

– 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 access to the engine compart-
ment.
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.

After replacement, refit
the covers correctly
checking 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 humidity in the air. These traces
will disappear when the beams are turned
on. Drops of water inside the headlight
indicate instead water infiltration: contact
Alfa Romeo Authorised Services.

IN AN EMERGENCY

Take care when position-
ing the arms of the lift or
workshop lift to avoid
damaging the side strips.
USING AN ARM LIFT OR
WORKSHOP LIFT
The vehicle should be lifted only at the
side, setting the end of the arms or the
workshop lift in the illustrated areas, at
approx. 40 cm from the wheelhouse pro-
file (fig. 57).These areas are highlighted by the sym-
bol
▼on the lower part of the side mem-
ber.
The car may fall if the
jack is not positioned cor-
rectly. Never use the jack
for higher capacities than the one
stated on the label.
IMPORTANTFor versions with
Selespeed transmission, make sure that
the gears are in neutral (N) (checking
that the vehicle moves if pushed) and
then proceed as for towing a normal car
with mechanical transmission, following
the instructions given previously.
Should it be impossible to set the gears
to neutral, do not tow the car and contact
Alfa Romeo Authorised Services.Do not start the engine
when towing the car.
