2016 Alfa Romeo 4C check engine

54)The tyre repair kit (Fix&Go) provided
with the car (for versions/markets, where
provided) is compatible with the TPMS
sensors; using sealants not equivalent with
that in the original kit may adversely affect
its operation. If sealants not equivalent with
the original one are used, it is
recommended to have the TPMS sensors
checked by a qualified repair centre.REFUELLING THE
CAR
The car features the "Fast Fuel" system,
which prevents refuelling with incorrect
fuels (e.g. diesel for a petrol engine).
Stop the engine before refuelling.
Only refuel with unleaded petrol with
octane rating (RON) not less than 95, in
compliance with the European
specification EN228. In particular, the
4C’s engine has been designed to
comply with all emission limits while
simultaneously guaranteeing minimal
consumption and maximum
performance, using premium-quality
unleaded petrol with octane rating
(RON) of 98 or higher.
In order to prevent damage to the
catalytic converter never introduce even
the smallest amount of leaded petrol,
even in the event of an emergency.
IMPORTANT An inefficient catalytic
converter leads to harmful exhaust
emissions, thus contributing to air
pollution.
IMPORTANT Never introduce leaded
petrol to the tank, even in small
amounts in an emergency, as this
would damage the catalytic converter
beyond repair.
FILLING THE TANK
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Avoid
further top-ups, which could cause
faults in the fuel supply system.
REFUELLING
PROCEDURE
The car features a "Fast Fuel" device,
integrated with the opening for the fuel
tank: it opens and recloses
automatically when the fuel supply gun
is inserted/removed.
The "Fast Fuel" device is provided with
an inhibitor which prevents refuelling
with incorrect fuel.
The refuelling procedure described
below is illustrated on the label
fig. 56 located inside the fuel flap. The
label also indicates the fuel type
(UNLEADED FUEL=petrol).

EBD FAILURE
The simultaneous switching on of the
(red) and
(amber) warning lights with the engine on, indicates
either a failure of the EBD system or that the system is
not available. In this case, the rear wheels may suddenly
lock and the vehicle may swerve when braking sharply.
The display shows the dedicated message.Drive very carefully to the nearest dedicated Alfa Romeo
Dealership to have the system inspected immediately.
redAIRBAG FAILURE
When the key is turned to MAR-ON, the warning light
switches on but should switch off after a few seconds.
The warning light stays on constantly if there is a fault in
the airbag system.
The display shows the dedicated message.
redSEAT BELTS NOT FASTENED
(for versions/markets, where provided)
The warning light switches on constantly with the car
stationary if the driver’s seat belt is not fastened.
The warning light flashes and a buzzer will sound if the
car is in motion and the driver’s seat belt is not correctly
fastened.For permanent deactivation of the SBR (Seat Belt
Reminder) system buzzer, contact the dedicated Alfa
Romeo Dealership. The system can be reactivated
using the Setup Menu.
WARNING
59)If thewarning light does not switch on when the key is turned to MAR or if it stays on when driving (together with the message on the
display), there may be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact a dedicated Alfa Romeo Dealership to have the
system checked immediately.

amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR-ON
the warning light switches on, but should switch off as soon as
the engine is started.
The operation of the
warning light may be checked by the traffic police using specific
devices. Comply with the laws and regulations of the country
where you are driving.
If the warning light stays on or switches on when driving, it means
that the injection system is not working properly; in particular, if
the warning light comes on constantly, this indicates a
malfunction in the supply/ignition system that could cause
excessive exhaust emissions, a possible loss of performance,
poor driveability and high fuel consumption.
On some versions, the display shows the dedicated
message.
The warning light switches off if the malfunction
disappears, but it is still stored by the system.
Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the engine.
Prolonged use of the car with the warning light
on constantly may cause damage.
Contact the dedicated Alfa Romeo Dealership
as soon as possible.
If the warning light flashes, it means that the catalytic converter
may be damaged.In this case, it is necessary to release the
accelerator pedal to lower the speed of the
engine until the warning light stops flashing.
Continue the journey at moderate speed, trying
to avoid driving conditions that may cause
further flashing and contact the dedicated Alfa
Romeo Dealership as soon as possible.

The digital warning light switches on when the
key is turned to MAR-ON, but it should switch off
after a few seconds. The warning light turns on
when the engine is overheated.
The display shows the dedicated message.In normal driving conditions: stop the car, switch off the engine
and check that the water level in the reservoir is not below the
MIN mark. In this case, wait for the engine to cool down, then
slowly and carefully open the cap, top up with coolant and
check that the level is between the MIN and MAX marks on
the reservoir itself. Also check visually for any fluid leaks.
Should the warning light turn on again at the next start-up,
contact a dedicated Alfa Romeo Dealership.
If the car is used under demanding conditions (e.g. in
high-performance driving): slow down and, if the warning light
stays on, stop the car. Wait for 2 or 3 minutes with the engine
running and slightly accelerated to further favour the coolant
circulation. Then stop the engine. Check that the coolant level
is correct as described above.
IMPORTANT Over demanding routes, it is advisable to keep
the engine on and slightly accelerated for a few minutes before
switching it off.

KNOWING THE INSTRUMENT PANEL

WARNING
72)Do not apply stickers or other objects
to the steering wheel or the passenger side
airbag cover. Do not place objects on the
passenger side of the dashboard because
these could interfere with the correct
opening of the passenger airbag and
cause injury to occupants.
73)Always drive keeping your hands on
the steering wheel rim so the airbag can
inflate freely if necessary. Do not drive with
your body bent forward. Keep your back
straight against the backrest.
74)Instructions for deactivating the front
passenger airbag can be found in the
"Menu Options" paragraph of the
"Knowing the instrument panel" chapter.
Please note that under these conditions
the airbag will NOT deploy when required
(accident).
75)Do not rest your head, arms or elbows
on the door to prevent injury during airbag
deployment.
76)Never lean your head, arms or elbows
out of the window.
77)If the
warning light does not switch
on when the key is turned to MAR, or stays
on while driving (on some versions together
with a message on the display) there may
be a fault in the restraint systems. In this
case, airbags or pretensioners may not be
activated in the case of an accident or (in a
lesser number of cases) they may be
activated incorrectly. Before proceeding,
contact a dedicated Alfa Romeo Dealership
to have the system checked immediately.78)Do not travel carrying objects on your
lap, in front of your chest or between your
lips (pipe, pencils, etc.): they could cause
severe injury if the airbag is deployed.
79)If the car has been subject to theft,
attempted theft, vandalism, or flooding,
have the airbag system inspected at a
dedicated Alfa Romeo Dealership.
80)The airbags may also be deployed
when the car is not moving, if the key is
inserted and turned to MAR even when the
engine is off, if the car is hit by another
moving vehicle. Also remember that no
safety device (airbags or pretensioners) will
activate in the event of impact when the
key is at STOP. Non-deployment of these
devices under these circumstances does
not therefore indicate a system
malfunction.
81)When the ignition key is turned to
MAR, the
warning light comes on
constantly for the first 4 seconds. Then, if
the warning light remains on, this means
the passenger's protection has been
deactivated; if the warning light switches
off, instead, the passenger's protection is
enabled.
82)The front airbag is designed to be
deployed for impacts of a greater intensity
than for the pretensioners. For impacts
whose intensity falls between the two
levels, normally, only the pretensioners will
be activated.
83)The airbag does not replace seat belts
but increases their efficiency. Because front
airbags are not deployed for low-speed
frontal impacts, side collisions, rear shunts
or rollovers, occupants are protected only
by their seat belts, which must always be
fastened.
93

WARNING
89)The Launch control function is only
available in Race mode. Regardless of
what is explicitly indicated in the
description of these modes, the ESC and
ASR systems are deactivated during
operation of the Launch Control function.
This means that vehicle dynamic control is
the sole responsibility of the driver.
Therefore pay the utmost attention when
using the Launch Control. Take into
account traffic and road surface conditions
and during manoeuvres make sure there is
enough room in the area concerned.
SAVING FUEL
Alfa Romeo has designed and built the
vehicle using technologies, materials
and devices able to reduce negative
environmental impact. Here are some
suggestions to further contribute to
environmental protection.
GENERAL
CONSIDERATIONS
Car maintenance
Have checks and adjustments carried
out in accordance with the “Scheduled
Servicing Plan”.
Tyres
Check the tyre pressures at least once
every four weeks: if the pressure is too
low, consumption levels increase as
resistance to rolling is higher.
Climate control system
The use of the climate control system
leads to higher fuel consumption. If the
temperature outside permits, try to use
ventilation only.
DRIVING STYLE
Starting
Do not warm the engine with the car at
a standstill or at idle or high speed:
under these conditions the engine
warms up much more slowly, increasing
consumption and emissions. It is
therefore advisable to move off
immediately, slowly, avoiding high
speeds: in this way the engine will
warm up more quickly.Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine. This action is absolutely
pointless and only increases
consumption and pollution.
Gear selection
Using a low gear for faster acceleration
increases consumption.
In the same way, improper use of a high
gear increases consumption, emissions
and engine wear.
Max. speed
Fuel consumption increases
considerably with speed. Maintain a
constant speed, avoiding unnecessary
braking and acceleration, which cost in
terms of both fuel consumption and
emissions.
Acceleration
Accelerating violently will greatly affect
consumption and emissions: avoid
frequent and strong accelerations.
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach
optimum operating temperature.
This results in a significant increase in
consumption levels (from +15 to +30%
on the urban cycle) and emissions.
101

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).
IMPORTANT
11)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.
CAR INACTIVITY
If the vehicle is to be left inactive for
longer than a month, observe the
following precautions:
park the car in covered, dry and if
possible well-ventilated premises and
slightly open the windows;
check that the handbrake is not
engaged;
disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage. For optimum
preservation of the battery charge, it is
advisable to use the charge-holder (for
versions/markets, where provided, or
alternatively, available from
Lineaccessori). For more details on its
operation, refer to the attached
Supplement;
if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
clean and protect the painted parts
using protective wax;
sprinkle talcum powder on the
rubber blade of the windscreen wiper
and lift it off the glass (for the correct
lifting procedure, refer to the
"Windscreen wiper" paragraph in the
"Maintenance and care" chapter);
cover the car with a cloth or
perforated plastic sheet. Do not use
sheets of non-perforated plastic as theydo not allow moisture on the car body
to evaporate;
inflate tyres to +0.5 bar above the
standard prescribed pressure and
check it periodically;
do not drain the engine cooling
system;
every time the car is left inactive for
two weeks or longer, run the air
conditioning system for about 5
minutes, set to outside air and with fan
set to maximum, with the engine idling;
this operation will ensure adequate
lubrication to minimise the possibility of
damage to the compressor when the
system is put back into operation;
ensure that the air intake directly in
front of the windscreen is not
obstructed by leaves or other foreign
bodies; any leaves in the air intake
could reduce the air flow and, if they
enter the reservoir, could prevent water
drainage. In winter months, make sure
that the air intake is not obstructed by
ice, mud or snow.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver side door, wait at least one
minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to the
battery, make sure that the ignition key
is in the STOP position and the driver
side door is closed.

STARTING THE
ENGINE
Contact the dedicated Alfa Romeo
Dealership immediately ifwarning
light stays on constantly on the
instrument panel.
JUMP STARTING
If the battery is flat, start the engine
using an auxiliary battery with the same
capacity or a little higher than the flat
one.
Proceed as follows to start the car:connect the positive terminals (+ sign
near the terminal) of the two batteries
with a jump lead fig. 81;
with a second lead, connect the
negative terminal(−)oftheauxiliary
battery to an earthing point
on the
engine or the gearbox/transmission of
the car to be started;
start the engine; when the engine
has started, remove the leads, reversing
the order above.
If after a few attempts the engine does
not start, do not persist but contact the
dedicated Alfa Romeo Dealership.
IMPORTANT Do not connect the
negative terminals of the two batteries
directly! If the auxiliary battery is
installed on another car, check that
there is no accidental contact between
metallic parts of the two cars.
BUMP STARTING
Never, under any circumstances, jump
start the engine by pushing, towing or
coasting downhill.
IMPORTANT
12)Never use a fast battery-charger to
start the engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and engine fuel
supply control units.
WARNING
91)This starting procedure must be
performed by expert personnel because
incorrect actions could cause electrical
discharge of considerable intensity.
Furthermore, battery fluid is poisonous and
corrosive: avoid contact with skin and
eyes. Keep naked flames and lighted
cigarettes away from the battery and do
not cause sparks.
