2015 Alfa Romeo 4C wheel

SERVICING AND MAINTENANCE
Correct maintenance permits the
performance of the car to be
maintained over time, as well as limited
running costs and safeguarding the
efficiency of the safety systems.

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. 128:
A normal pressure: tread evenly worn;
B low pressure: tread particularly worn
at the edges;
C high pressure: tread particularly
worn in the centre.The tyres must be replaced when the
tread is less than 1.6 mm thick. In
any case, follow the laws in force in the
country you are in.
IMPORTANT
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 car
overloaded. If a tyre is punctured,
stop immediately and change it;❒tyres age even if they are not used a
great deal. 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;
❒if replaced, always fit new tyres,
avoiding those of dubious origin;
❒if a tyre is changed, also change the
inflation valve.
WARNING
131) The road holding qualities of
the car also depend on the correct
inflation pressure of the tyres.
132) If tyre pressure is too low, it
may overheat and be severely
damaged as a result.
133) Do not switch tyres from the
left to the right side and vice
versa, in order to prevent
inversion of the rotation direction.
134) Do not repaint alloy wheel rims
at temperatures higher than
150°C. The mechanical
characteristics of the wheels
could be compromised.

135) The car is always equipped with
front and rear wheels of different
dimensions. It is not therefore
possible to move the wheels from
the front to the back and vice
versa.WINDSCREEN
WIPER
It is advisable to replace the blade
about once a year.
136)
A few simple precautions can reduce
the possibility of damage to the blade:
❒if the temperature falls below zero,
make sure that ice has not frozen
the rubber to the glass. Use an
antifreeze product to release it if
required;
❒remove any snow from the glass;
❒do not operate the windscreen wiper
on dry glass.
IMPORTANT Do not lift the arm of the
windscreen wiper when it is in its initial
rest position. Refer to the following
instructions to lift the windscreen wiper
blade correctly.
Lifting blade
If it is necessary to lift the blade from
the windscreen (e.g. in the event of
snow or if the blade needs
replacement) proceed as follows:
❒turn ring nut A fig. 129 to
(wiper
off);
❒turn the ignition key to MAR-ON and
then to STOP;❒after turning the ignition key to STOP,
within 2 minutes move the right stalk
upwards, into unstable ("anti-panic")
position, for at least half a second.
The windscreen wiper then executes
part of a stroke; at each command,
approximately 1/3 of a normal wiper
stroke is triggered.
❒the previous operation can be
repeated up to 3 times, in order to
move the blade to the most suitable
position;
❒lift the blade from the windscreen and
proceed with the required operation;
❒lower the blade, bringing it into
contact with the windscreen;
❒bring the blade to the initial rest
position, turning the ignition key
to MAR-ON.

SERVICING AND MAINTENANCE

❒tighten the screws with folding ring A
fig. 132 in the housings on the floor;
❒unite the Velcro fabric strips of the
mats with those on the floor, taking
care to apply light pressure and
ensure that the fastening is efficient.
139)
SEATS AND FABRIC OR
MICROFIBRE PARTS
Remove dust with a soft brush or a
vacuum cleaner. For better cleaning of
microfibre trim (including the steering
wheel, for versions/markets, where
provided) we advise you to moisten the
brush. Rub the seats with a sponge
moistened with a solution of water and
neutral detergent.LEATHER SEATS
(for versions/markets, where provided)
Remove the dry dirt with a chamois
or slightly damp cloth, without exerting
too much pressure. Remove any liquid
or grease stains using an absorbent
dry cloth, without rubbing. Then clean
with a soft cloth or chamois moistened
with water and mild soap. If the stain
persists, use specific products and
observe the instructions carefully.
IMPORTANT Never use alcohol. Make
sure that the cleaning products used
contain no alcohol or alcohol
derivatives, even in small quantities.PLASTIC, CARBON AND
COATED PARTS
Clean interior plastic and visible carbon
parts with a damp cloth (if possible
made from microfibre), and a solution of
water and neutral, non-abrasive
detergent. To clean oily or persistent
stains, use specific products free from
solvents and designed to maintain
the original appearance and colour of
the components.
Remove any dust using a microfibre
cloth, if necessary moistened with
water. The use of paper tissues is not
recommended as these may leave
residues.
IMPORTANT Do not use alcohol,
petrols or derivatives to clean
the instrument panel display.

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
