2006 Alfa Romeo 147 tyre pressure

IN AN EMERGENCY
193
INFLATING PROCEDURE
– Place the wheel in the position illustrated
in the figure (A-fig. 14) for the operation
with the valve, then engage the hand-
brake.
– Screw the filling pipe (B-fig. 15) to
the bottle (C).
– Unscrew the tyre valve plug, remove the
element inside the valve by using the ap-
propriate tool (D-fig. 16); be careful not
to place it on the sand or on a dirty surface.
– Introduce the filling pipe (B-fig. 17)
in the tyre valve, keep the bottle (C) with
the pipe directed downwards, then press the
bottle so that the whole sealer can get into
the tyre.– Screw again the element inside the
valve with the tool (D-fig. 18).
– Use the appropriate lever (E-fig. 19)
to insert and clamp the air compressor pipe
(F) to the tyre valve.
– Start the engine, insert the plug (G-
fig. 20) in the lighter (or current socket,
where fitted) and inflate the tyre according
to the right pressure value (see “Cold infla-
tion pressures” in the “Technical specifica-
tion”). You are advised to check the tyre
pressure value on the pressure gauge (H-
fig. 19) with the compressor off, in order
to have a more accurate reading.If it is not possible to reach the prescribed
pressure, move the car forwards or back-
wards for about 10 metres, so that the seal-
er is distributed inside the tyre, then repeat
inflation.
If, in spite of the last operation, the pre-
scribed pressure is not achieved, do not
move the vehicle and contact Alfa Romeo
Authorized Services.
Once the correct tyre pressure has been
reached, start driving immediately so that
the sealer is distributed evenly inside the
tyre.

After about 10 minutes, stop and check
the tyre pressure once again; remember to
engage the handbrake.
Place the sticker in a posi-
tion where it can be clear-
ly seen by the driver as a notice
that the tyre has been treated with
the quick repairing kit. Drive care-
fully especially in a bend. Do not
overcome 80 km/h. Avoid sudden
acceleration or braking.
WARNING
If the pressure is below
1,3 bars do not drive any
further: the quick repairing kit can-
not guarantee proper hold because
the tyre is too much damaged. Con-
tact Alfa Romeo Authorized Ser-
vices.
Conversely, if at least 1,3 bars are
detected, restore the correct pres-
sure (with the engine running and
the handbrake engaged) and start
driving the car with great care.
WARNING
If, during the pressure
restoring operation, it is
not possible to reach at least 1,8
bars, do not drive any further be-
cause the tyre is too much dam-
aged and the quick repairing kit
cannot guarantee proper hold. Con-
tact Alfa Romeo Authorized Ser-
vices.
WARNING

VEHICLE MAINTENANCE
221
It is however wise to remember that Pro-
grammed Maintenance does not complete-
ly cover all the car’s requirements: also in
the initial period before the 20,000 km ser-
vice coupon and later, between one coupon
and another, ordinary care is still necessary
such as for example routinely checking and
topping up the level of fluids, checking the
tyre pressure, etc...
IMPORTANTThe Programmed Mainte-
nance coupons are specified by the Manu-
facturer. The failure to have them carried out
may invalidate the warranty.
The Programmed Maintenance service is
carried out by all Alfa Romeo Authorised Ser-
vices, at pre-established times.If during each operation, in addition to the
ones programmed, the need arises for fur-
ther replacements or repairs, these may be
carried out only with the explicit agreement
of the customer.
IMPORTANTYou are advised to contact
Alfa Romeo Authorised Services in the event
of any minor operating faults, without wait-
ing for the next service coupon. SCHEDULED
SERVICING
Correct maintenance is determinate in en-
suring long vehicle life under the best con-
ditions.
This is why Alfa Romeo has programmed
a series of checks and maintenance opera-
tions every 20,000 km.
IMPORTANTOn versions fitted with re-
configurable multifunction display, at 2000
km from the maintenance deadline, the dis-
play will show “REFER TO SERVICE MANU-
AL” which is shown again turning the igni-
tion key to MAR, every 200 km. For fur-
ther details, see “Service” in the “Recon-
figurable multifunction display” paragraph.

– Do not check for current in the cables by
short-circuiting the ends.
– If electric welding is to be carried out on
the body, remember to disconnect the elec-
tronic control units, or remove them if the
work involves high temperatures.ELECTRONIC
CONTROL UNITS
With normal use of the vehicle. no partic-
ular precautions need to be taken.
In the event of work on the electric system
or emergency starting, the instructions giv-
en below must absolutely be adhered to:
– Always switch off the engine before dis-
connecting the battery from the electric sys-
tem.
– If it is necessary to charge the battery,
always disconnect it from the electric sys-
tem.
– When starting in an emergency, only
use an auxiliary battery and not a battery
charger.
– Check that the bias is correct and that
the connections between the battery and
the electric system are in efficient conditions.
– Before disconnecting or connecting the
terminals of electronic units, ensure that the
ignition key is not in the MARposition.
WHEELS AND TYRES
TYRE PRESSURE
Check the tyre pressure of every wheel, in-
cluding the spare.
The pressure should be checked with the
tyre rested and cold.
It is normal for the pressure to increase
when the car is in use. Should it become
necessary to restore the pressure with the
tyre hot, bear in mind that the pressure
should be +0.3 bar compared with the spec-
ified rating.
For the correct tyre inflation pressure, see
wheels in the “Technical Specifications”
chapter.
Alterations or repairs to
the electric system carried
out incorrectly and without taking
account of the specifications of the
system, may cause operating faults
with the risk of fire.
WARNING
Remember that vehicle
road holding also depends
on correct tyre inflation pressure.
WARNING

VEHICLE MAINTENANCE

Incorrect pressure causes abnormal tyre
wear (fig. 11):
A- Normal pressure: tread evenly worn.
B- Low pressure: tread particularly worn
at the edges.
C- High pressure: tread particularly worn
in the centre.
Tyres should be changed when the tread
thickness is reduced to 1.6 mm. In any case
follow local regulations.
fig. 11
A0A0225m
IMPORTANT
Where possible, avoid suddent braking,
tyre squealing starts, etc.
Particularly avoid violent bumps against
kerbs, potholes or obstacles of various kinds.
Prolonged driving on rough roads may dam-
age the tyres. Routinely check the tyres for
cuts on the sides, swellings or uneven tread
wear. If necessary contact Alfa Romeo Au-
thorised Services.
Avoid overloading the vehicle when trav-
elling: this may cause serious damage to the
wheels and tyres.
If a tyre is punctured, stop immediately
and change it to avoid damage to the tyre
itself, the rim, suspensions and steering sys-
tem. Tyres age even if they are not used
much. Cracks in the tread rubber are a sign
of aging. In any case, if the tyres have been
on the vehicle for over 6 years, they should
be checked by specialised personnel, to see
if they can still be used.In the case of replacement, always fit new
tyres, avoiding those of dubious origin.
The
Alfa 147 GTAuses Tubeless
tyres. Never use an inner tube with these
tyres.
If a tyre is changed, also change the infla-
tion valve.
To allow even wear between the front and
rear tyres it is advisable to change over every
10-15 thousand kilometres, keeping them
on the same side of the car so as not to re-
verse the direction of rotation (fig. 12).
fig. 12
A0A0459m
Excessively low pressure
causes overheating of the
tyre with the possibility of serious
damage to it.
