environmental protection.
NOTE These symbols, when necessary, are reported at the end of each paragraph and are followed by a number. That number recalls the
corresponding warning at the end of the relevant section.
In the attached Warranty Booklet you will also find a description of the Services that Alfa Romeo offers to its customers, the Warranty
Certificate and the detail of the terms and conditions for maintaining its validity.
We are sure that these will help you to get in touch with and appreciate your new car and the service provided by the people at Alfa Romeo.
The Alfa Romeo 4C is a truly exclusive car in terms of content and technology; for this reason and to guarantee the highest level of service, Alfa
Romeo has provided a dedicated Dealership for 4C customers. Up-to-date information on service centres is available on freephone number
00 800 2532 4200 (should this number be unavailable, use the international toll number +39 02 44412 987, or anyway refer to the instructions
in the Warranty Booklet).
Enjoy reading and happy motoring!
This Owner Handbook describes all versions of the Alfa Romeo 4C; please consider only the information relevant to your
car’s trim level, engine and version. All data contained in this publication is purely indicative. Fiat Group Automobiles can
modify the specifications of the vehicle model described in this publication at any time, for technical or marketing
purposes. For further information, contact the dedicated Alfa Romeo Dealership.

SNOW TYRES
Use snow tyres of the same size as the
normal tyres provided with the car:
the dedicated Alfa Romeo Dealership
will be able to advise you on the most
appropriate tyre to use.
Only use these tyres in the event of ice
or snow on the roads. In these
conditions it is recommended to select
the "All Weather" mode of the Alfa
DNA system.
For the type of tyre to be used, inflation
pressures and the specifications of
snow tyres, follow the instructions given
in the "Wheels" paragraph in the
"Technical specifications" chapter.
90)
The performance of these tyres on
low-grip surfaces are reduced
considerably when the tread depth is
below 4 mm. They should be replaced
in this case.
Due to the specific characteristics of
snow tyres, in normal weather
conditions and dry asphalt or on long
motorway journeys, the performance of
these tyres is lower than that of
standard tyres. Their usage should
therefore be restricted in accordance
with their type approval.IMPORTANT When using snow tyres
with a maximum speed index below the
one that can be reached by the car
(increased by 5%), place a notice in the
passenger compartment, plainly in
view, which states the maximum speed
allowed by the snow tyres (as per EC
Directive).
All four tyres should be the same brand
to ensure greater safety when driving
and braking as well as making the
car more responsive. It is inadvisable to
change the rotation direction of tyres.
Refer to the "Raising the car" section in
the "In an emergency" chapter for
further details on how to raise the car
correctly.
WARNING
90) The maximum speed for snow
tyres marked “Q” is 160 km/h,
while it is 190 km/h for “T” tyres
and 210 km/h for "H" tyres. The
highway code speed limits must
however always be complied with.
SNOW CHAINS
Reduced size snow chains with a
maximum projection of 7 mm beyond
the tyre profile can be fitted only on
235/40 R18 rear tyres.
The use of snow chains should be in
compliance with local regulations.
Snow chains can be fitted on the tyres
of the rear wheels (drive wheels) only.
19" rear tyres cannot be fitted with
chains.
Check the tension of the snow chains
after the first few metres have been
driven.
11)
IMPORTANT Snow chains cannot be
fitted to the space-saver wheel (for
versions/markets, where provided).

CHANGING A BULB
15)
106) 107) 108)
GENERAL
INSTRUCTIONS
❒Before changing a bulb check the
contacts for oxidation;
❒replace blown bulbs with others of
the same type and power;
❒after replacing a headlight bulb,
always check its alignment;
❒when a light is not working, check
that the corresponding fuse is intact
before changing the bulb. For the
location of fuses, refer to the
paragraph “If a fuse blows” in this
chapter.IMPORTANT
15) Halogen bulbs must be handled
by holding the metallic part only.
Touching the transparent part
of the bulb with your fingers may
reduce the intensity of the
emitted light and even reduce the
lifespan of the bulb. In the case
of accidental contact, rub the
lamp with a cloth and spirit and
leave to dry.
WARNING
106) Modifications or repairs to the
electric system that are not
carried out properly or do not take
the system technical
specifications into account can
cause malfunctions leading to the
risk of fire.
107) Halogen bulbs contain
pressurised gas; in the case of
breakage they may burst.108) Due to the high supply voltage,
gas discharge bulbs (Bi-Xenon)
should only be replaced by
specialised personnel: danger of
death! Contact a dedicated Alfa
Romeo Dealership.
IMPORTANT When the weather is cold
or damp or after heavy rain or washing,
the surface of headlights or rear lights,
may steam up and/or form drops of
condensation on the inside. This is
a natural phenomenon due to the
difference in temperature and humidity
between the inside and the outside
of the glass which does not indicate a
fault and does not compromise the
normal operation of lighting devices.
The mist disappears quickly when the
lights are turned on, starting from
the centre of the diffuser, extending
progressively towards the edges.

SERVICING AND MAINTENANCE

ENGINE OIL
Check that the oil level is between the
MIN and MAX marks on the dipstick
A fig. 119.
For this check, take out the dipstick
from its seat, clean it with a lint-free
cloth, reinsert the dipstick; take it out
again and check the oil level.
121)
If the oil level is near or under the MIN
mark, add oil through the filler B fig.
119 until it reaches the MAX mark.
22)
Take out the engine oil dipstick A, clean
it with a lint-free cloth and reinsert it.
Extract the engine oil dipstick again and
check that the level is between the
MIN and MAX marks on the dipstick.
121)
Make sure to tighten the oil plug in
its seat thoroughly after possibly
topping the oil up.
The range between the MIN and MAX
levels corresponds to approximately
1 litre of oil.
Engine oil consumption
23)3)
The maximum engine oil consumption
is usually 400 grams every 1,000 km.When the car is new, the engine needs
to run in, therefore the engine oil
consumption can only be considered
stabilised after the first 5,000 - 6,000
km.
IMPORTANT After adding or changing
the oil, let the engine run for a few
seconds and wait a few minutes after
stopping it before you check the level.
ENGINE COOLANT
24)122)
The coolant level must be checked
when the engine is cold and must
range between the MIN and MAX
marks on the reservoir.
If the level is too low, unscrew reservoir
plug C fig. 119 and add the fluid
described in the "Fluids and lubricants"
paragraph of the "Technical
Specifications" chapter.
WINDSCREEN WASHER
FLUID
123) 124)
To check the windscreen washer fluid
level, proceed as follows:
❒to avoid any interference during the
procedure, lift the windscreen wiper
blade according to the "Windscreen
wiper" paragraph in the
"Maintenance and care" chapter;❒loosen the 4 self-tapping screws A
fig. 121 using the supplied
screwdriver. Remove the engine
cover grille;
❒release the plug from the opening;
❒leaving the plug close to the opening,
put a finger on the central hole B fig.
122 in the plug and remove it: the
level can be seen on the control pipe
C fig. 123 due to capillarity;
❒after the check, reinsert the plug B
with the control pipe C in the initial
position;
❒reposition the engine cover grille and
tighten the 4 self-tapping screws A.
WARNING Re-close the plug holding it
horizontally (not directed towards the
engine cover) to prevent the opening
tang from remaining locked in a position
difficult to reach.

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.
