CORRECT USE OF THE CAR
185
IMPORTANTWhen winter tyres are
used with a maximum speed index below
the one that can be reached by the vehicle
(increased by 5%), place a notice in the pas-
senger compartment, plainly in the driver’s
view which states the maximum permissi-
ble speed of the winter tyres (as per CE Di-
rective).
Fit the same type of tyre on all four wheels
(brand and profile) to ensure higher driving
safety when braking and good handling.
Remember that it is inappropriate to
change the direction of rotation of tyres. WINTER TYRES
These tyres are specially designed for dri-
ving on snow and ice, to be fitted in re-
placement of those fitted on the car.
Use winter tyres of the same size as the
normal tyres provided on the car.
Alfa Romeo Authorised Services will be
pleased to advise you on the choice of the
car most suited to the use the Customer in-
tends to make of it.
For the type of tyre to be used, inflation
pressures and the specifications of winter
tyres, follow the instructions given in the
“Technical Specifications” chapter.
The winter features of these tyres are re-
duced considerably when the tread depth
is below 4 mm. In this case, they should be
replaced.
Due to the winter features, under normal
conditions of use or on long motorway jour-
neys, the performance of these tyres is low-
er than that of normal tyres.
It is necessary therefore to limit their use to
the purposes for which they are certified.
TRAILER TOWING
The car does not have the approval to tow
trailers.

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.

VEHICLE MAINTENANCE
236
– 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.
