IMPORTANT
This Owner Handbook describes all Alfa 4C versions. Options, equipment dedicated to specific markets or versions are not explicitly
indicated in the text: as a consequence, you should only consider the information which is related to the trim level, engine and version
that you have purchased. Any content introduced throughout the production of the model, outside the specific request of options at the
time of purchase, will be identified with the wording (where provided).
All data contained in this publication are intended to help you use your vehicle in the best possible way. FCA Italy S.p.A. aims at a
constant improvement of the vehicles produced. For this reason it reserves the right to make changes to the model described for
technical and/or commercial reasons.

Warning lights on panelMeaningWhat to do
In any situation in which the message is “See manual”, it is
ESSENTIAL to refer to the contents of the “Wheels”
paragraph in the “Technical data” chapter, strictly
complying with the indications that you find there.
Low tyre pressure - See manual
The warning light switches on, together with a dedicated
message on the display, to indicate that the tyre pressure
is lower than the recommended value and/or that slow
pressure loss is occurring. In these circumstances, optimal
tyre duration and fuel consumption may not be
guaranteed.
Should two or more tyres be in the condition mentioned
above, the display will show the indications corresponding
to each tyre in sequence.
Contact a dedicated Alfa Romeo Dealership as soon as
possible. TPMS system fault
The warning light switches on when a fault is detected in
the TPMS.
Should one or more wheels be fitted without sensors, the
display will show a warning message until initial conditions
are restored.IMPORTANT Do not continue driving with one or more flat
tyres as handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair immediately
using the dedicated kit (see “Repairing a wheel” paragraph
in the “In an emergency” chapter) and contact the
dedicated Alfa Romeo Dealership as soon as possible. TPMS SYSTEM

INFLATION PROCEDURE
Proceed as follows:
107)
❒ engage the handbrake, unscrew the
tyre valve cap, take out filler hose
1 fig. 80 and tighten ring nut 2 on the tyre
valve;
80A0L0078
❒ make sure that switch 1 fig. 81 for the
compressor is in position 0 (off), start the
engine, insert the plug into the cigar
lighter socket on the central tunnel
(see fig. 82) and switch on the
compressor by bringing switch 1 fig. 81
to I (on);
82A0L0080
❒ inflate the tyre to the pressure
indicated in the “Wheels” paragraph in the
“Technical data” chapter. In order to
obtain a precise reading, check the
pressure on pressure gauge 1 fig. 81 with
the compressor off;
❒ if after 5 minutes it is impossible to
reach at least 1.8 bar,
❒ disconnect the compressor from the
valve and power socket, then move the
car forwards approximately 10 metres in
order to distribute the sealant inside the
tyre evenly, then repeat the inflation
operation;
❒ if you still cannot obtain a pressure of
at least 1.8 bar within 5 minutes from the
compressor switching on, do not drive off
and contact a dedicated Alfa Romeo
Dealership;
❒ after driving for about 10 minutes
stop and check the tyre pressure again;
remember to engage the handbrake;
❒ if a pressure value of at least 1.8 bar
is detected, restore the correct pressure
(with the engine running and the
handbrake engaged), resume driving and
drive with great care to a dedicated Alfa
Romeo Dealership.

COLD TYRE INFLATION PRESSURE (bar)
Tyres provided Inflation pressure (bar)
Front tyres 205/45 R17 88Y XL 1.8 205/40 R18 86Y XL 1.8
Rear tyres 235/40 R18 95Y XL 2.0 235/35 R19 91Y XL 2.0
When the tires are warm, the inflation pressure should be + 0.3 bar in relation to the recommended figure.
However, recheck that the value is correct with the tyre cold.
With snow tyres, add +0.2 bar to the pressure value prescribed for standard tyres.
If it is necessary to raise the vehicle, refer to the “Raising the vehicle” paragraph in the “Servicing and care” chapter.
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 snow tyre to be used, inflation pressures and the specifications of the tyres, carefully follow the instructions given in
this paragraph.
134)
The performance of these tyres on low-grip surfaces are reduced considerably when the tread depth is below 4 mm. Replace them 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.

TECHNICAL DATA
126
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.
235/35 R19 rear tyres cannot be fitted with chains.
Check the tension of the snow chains after the first few metres have been driven.
27)
27)Keep your speed down when snow chains are fitted; do not exceed 50 km/h (or the equivalent in miles). Avoid potholes, do not drive over
steps or sidewalks and do not drive long distances over roads without snow, to avoid damaging both your vehicle and the road surface.
