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.

RIMS AND TYRES
Alloy rims.
Radial Tubeless tyres.
The Log book shows all the homologated
tyres.
IMPORTANTIn the event of any dis-
crepancies between this Handbook and the
vehicle Log Book, only the latter should be
considered.
While the specified dimensions remain the
same, for driving safety, the vehicle must be
fitted with tyres of the same brand and type
on all wheels.
IMPORTANTDo not use inner tubes
with Tubeless tyres.

(*) 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.
