BATTERY
The battery is of the “Limited Mainte-
nance” type and is fitted with an optical in-
dicator (A-fig. 9) for checking the elec-
trolyte level and charge.
Under normal conditions of use the elec-
trolyte does not need topping up with distilled
water. To make sure that it is in efficient con-
ditions, at routine intervals check the indica-
tor on the battery cover which should be dark
in colour with a green central area.
If the indicator is a bright light colour, or
dark without the green central area, contact
Alfa Romeo Authorised Services.

Batteries contain harmful
substances for the environ-
ment. To change the bat-
tery we advise contacting Alfa
Romeo Authorised Services who
are equipped for disposal respect-
ing nature and the law.
The incorrect installation
of electric accessories may
cause serious damage to
the vehicle. If after buying the car
you wish to install accessories
(alarm, radio, radiotelephone etc.)
contact Alfa Romeo Authorised
Services who will be able to sug-
gest the most suitable devices and
above all advise about the need to
use a more powerful battery.
If the car is to remain in-
active for a long time in
very cold conditions, re-
move the battery and take it to a
warm place, otherwise it may
freeze.
The liquid contained in the
battery is poisonous and
corrosive. Avoid contact with the
skin or eyes. The battery should be
charged in a well ventilated place
away from naked flames or pos-
sible sources of sparks: danger of
explosion and fire.
WARNING
When working on the bat-
tery or near to it, always
protect the eyes with goggles.

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.

(*) The toe-in value, primes to mm conversion, is always calculated taking into account a 15" rim regardless of rims actually used. Should it be impossible
to set the 15" rim at the test bench, refer to primes value. The toe-in value, tolerance included, shall always be evenly distributed between the two wheels.
