PERIODIC CHECKS
Every 1,000 km or before long
journeys, check and, if necessary, top
up the following:
❒engine coolant level;
❒brake fluid;
❒screen washer fluid;
❒tyre inflation pressure and condition;
❒operation of lighting system
(headlamps, direction indicators,
hazard warning lights, etc.);
❒operation of screen washing/wiping
system and positioning/wear of
wiper blade.
Every 3,000 km, check and top up if
required: engine oil level.
HEAVY-DUTY USE OF
THE CAR
If the car is used mainly under one of
the following conditions:
❒if the car is used under demanding
conditions, e.g. on track;
❒dusty roads;
❒short, repeated journeys (less than
7–8 km) at sub-zero outside
temperatures;
❒engine often idling or driving long
distances at low speeds or long
periods of inactivity;
the following checks must be carried
out more often than indicated in the
Scheduled Servicing Plan:
❒check of front and rear disc brake
pad condition and wear;
❒check cleanliness of tailgate locks,
cleanliness and lubrication of linkage;
❒visually inspect conditions of: engine,
gearbox, transmission, pipes and
hoses (exhaust - fuel system -
brakes) and rubber elements (boots -
sleeves - bushes - etc.);
❒check battery charge and battery
fluid level (electrolyte);
❒visually inspect condition of the
accessory drive belts;❒check and, if necessary, change
engine oil and replace oil filter;
❒check and, if necessary, replace air
cleaner.
Using the car on track should be
regarded as an exception. The car has
been designed and produced for road
use.

SERVICING AND MAINTENANCE

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.

COLD TYRE INFLATION PRESSURE (bar)
Tyres provided Inflation pressure (bar)
Front tyres205/45 R17 88Y XL 1.8

Rear tyres235/40 R18 95Y XL 2.0
235/35 R19 91Y XL 2.0
When the tyres are warm, add +0.3 bar to the pressure value prescribed. However, check that the value is correct with cold
tyres.
With snow tyres, add +0.2 bar to the pressure value prescribed for standard tyres.
If it is necessary to raise the car, refer to the "Raising the car" paragraph in the "In an emergency" chapter.
