IMPORTANT
28)Incorrect installation of electric and
electronic devices may cause severe
damage to your car. Contact a dedicated
Alfa Romeo Dealership if you want to install
accessories (anti-theft systems, etc.) after
purchasing the car. They can suggest the
most suitable devices and above all advise
you whether a higher capacity battery
needs to be installed.
IMPORTANT
4)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact a dedicated
Alfa Romeo Dealership.
WHEELS AND TYRES
Before embarking on a long trip, and
every two weeks, check the tyre
inflation pressure. Check the tyres when
cold.
131) 132) 133) 134) 135)
It is normal for the pressure to increase
when the car is used; for the correct
tyre inflation pressure, see “Wheels” in
the “Technical specifications” section.
Incorrect pressure causes abnormal
tyre wear fig. 131:
Anormal pressure: tread evenly worn;
Blow pressure: tread particularly worn
at the edges;
Chigh pressure: tread particularly worn
in the centre.
The tyres must be replaced when the
tread is less than 1.6 mm thick. In anycase, follow the laws in force in the
country where you are driving.
IMPORTANT NOTES
For versions/markets, where provided,
the 4C may be equipped with
high-performance tyres able to
guarantee superior grip; this results,
however, in increased wear. Alfa
Romeo, together with Pirelli, has indeed
developed special tyres for 4C: a
dedicated series of Pirelli PZero,
initialled AR, meeting the technical
specifications necessary to get the car
best performance.
Take the following precautions to
prevent damage to the tyres:
avoid violent impact against the
kerb, potholes or obstacles as well as
driving for extended periods on uneven
road surfaces;
periodically check that the tyres have
no cuts in the side wall, abnormal
swelling or irregular tread wear;
avoid travelling with the vehicle
overloaded. If a tyre is punctured, stop
immediately and change it;
tyres age even if they are not used
much. Cracks in the tread and on the
sidewalls are a sign of ageing. Have the
tyres checked by specialised personnel
if they have been fitted for longer than 6
years;
in the case of replacement, always
fit new tyres, avoiding those of

RIMS AND TYRES
RIMS AND TYRES
Alloy rims. Tubeless radial carcass
tyres. All approved tyres are listed in the
Registration Document.
IMPORTANT If there are any
discrepancies between the Owner
Handbook and the Registration
Document, take the information from
the latter.
For safe driving, the car must be fitted
with tyres of the same make and type
on all wheels.
IMPORTANT Do not use air chambers
with tubeless tyres.
