You are also reminded that services with
high current absorption switched on by the
user, such as for example: baby bottle warm-
ers, vacuum cleaner, mobile phone, mini
fridge, etc., quicken the battery draining
processif they are turned on with
the engine offor running at idle speed.
IMPORTANT When installing addition-
al systems on the vehicle, bear in mind that
improper branches on connections of the ve-
hicle wiring are dangerous, particularly if
safety devices are involved.

The maximum absorption of all the ac-
cessories (standard and fitted afterwards)
should be 0.6 mA x Ah (of the battery), as
shown in the following table:CHANGING THE BATTERY
When changing the battery it should be re-
placed with another original one with the
same characteristics. If it is replaced by a
battery with different characteristics, the
maintenance intervals given in the Sched-
uled Maintenance Programme in this chap-
ter are no longer valid and for maintenance
it will be necessary to follow the battery
Manufacturer’s instructions.
USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERY
To avoid rapidly draining the battery and
ensure that it continues to work correctly,
the following should be noted:
– The terminals must always be firmly
tightened.
– Within reason, avoid using electrical de-
vices for a long time when the engine is
switched off (radio, hazard warning lights,
parking lights, etc.).– When the vehicle is parked in a garage,
ensure that the doors, bonnet, boot and in-
ner lids are closed properly so that the lights
do not stay on permanently.
– Before carrying out any work on the
electric system, disconnect the negative ca-
ble from the battery.
– If after buying the car, you wish to in-
stall electric accessories which require a per-
manent electric supply (alarm, voice feature,
radionavigator with satellite antitheft func-
tion etc.) or accessories that burden the elec-
tric system, contact Alfa Romeo Authorised
services whose qualified personnel, in ad-
dition to suggesting the most suitable de-
vices belonging to Lineaccessori Alfa Romeo,
will evaluate the overall electric absorption,
checking whether the vehicle’s electric sys-
tem is capable of withstanding the load re-
quired, or whether it should be integrated
with a more powerful battery. In fact, as
some of these devices continue absorbing
energy even when the ignition key is off (car
stationary, engine off), they gradually drain
the battery.

– 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.

CLEANING LEATHER SEATS
– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid and grease stains with
a dry absorbent cloth without rubbing. Then
wipe with a soft cloth or chamois leather
with water and neutral soap. If the stain per-
sists, use specific products, carefully follow-
ing the instructions for use.
IMPORTANTNever use alcohol. Make
sure that cleaning products do not contain
alcohol and alcohol derivatives even at low
strength.
INTERIOR PLASTIC PARTS
Use appropriate products designed to pre-
serve the appearance of components.
IMPORTANTNever use spirit or petro-
leum to clean the instrument cluster. Engine compartment
At the end of the winter the engine com-
partment should be carefully washed, with-
out directing the jet against electronic con-
trol units. Contact a specialised workshop to
have this done.
INTERIOR FITTINGS
Periodically check that water is not trapped
under the mats (due to water dripping off
shoes, umbrellas, etc.) which could cause ox-
idisation of the sheet metal.
Detergents cause water
pollution. Therefore the en-
gine compartment should
be washed in areas equipped for
collecting and purifying the liquid
used in the washing process.
IMPORTANTThe vehicle should washed
with the engine cold and the ignition key at
STOP. After washing make sure that the
various protections (e.g. rubber caps and
various covers) have not been damaged or
removed.CLEANING SEATS AND FABRIC
AND VELVET PARTS
– Use a soft brush or vacuum cleaner to
remove dust. Velvet is cleaned better if the
brush is moistened.
– Rub the seats with a sponge moistened
with a solution of water and neutral deter-
gent.
Never use inflammable
products like fuel oil ether
or rectified petrol for cleaning inside
the car. The electrostatic charges
generated when rubbing to clean
may cause fire.
WARNING
Do not keep aerosol cans in
the car. They might ex-
plode. Aerosol cans must never be
exposed to a temperature above
50°C. The temperature inside the
car exposed to the sun may go well
beyond that figure.

SPARK PLUGS
Clean, intact spark plugs are determinant
with regard to engine efficiency and for re-
ducing the emission of pollutants.Spark plugs should be re-
placed at the intervals
specified in the Scheduled
maintenance programme. Only use
spark plugs of the specified type:
if the thermal capacity is inade-
quate or if the envisaged life is not
guaranteed inconveniences may en-
sue.
BRAKES
Service brakes: – front
– rear
Parking brake
If examined by an expert eye, the ap-
pearance of a spark plug is a sound clue
for locating a fault, even if not involving the
ignition system. Therefore if you are expe-
riencing any engine problems, it is impor-
tant to have the spark plugs checked by Al-
fa Romeo Authorized Services.

POWER WINDOWS
For some versions, the power windows are
fitted with a safety system with crush-pre-
vention seals. The electronic control unit that
operates the system is capable of detect-
ing the presence of an obstacle during the
window closing motion through the special
seals. Should this occur, the system stops
the movement of the window and reverses
it immediately.
IMPORTANTIf the crush-prevention
function is operated for 3 times in 1 minute,
the system automatically sets to the recov-
ery mode (self-protection). To reset the cor-
rect system operating logic, use the control
button. The window will rise in predefined
steps until closing completely. The logic is re-
set and if there are no faults, the window
winder automatically resumes normal oper-
ation; if not, contact Alfa Romeo Authorised
Services.
With the ignition key at STOPor removed,
the power windows remain activated for
about 3 minutes and are deactivated im-
mediately the moment a door is opened.
