check engine Alfa Romeo 4C 2015 Owner handbook (in English)

IMPORTANT
11) Keep your speed down when
snow chains are fitted; do not
exceed 50 km/h. Avoid potholes,
steps and pavements and avoid
driving for long distances on
roads not covered with snow to
prevent damaging the car 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 they do 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;

REPLACING FUSES
GENERAL INFORMATION
Fuses protect the electrical system:
they intervene (blow) in the event of a
fault or improper action on the system.
When a device does not work, check
the condition of its fuse: the filament
A fig. 110 must be intact.
If it is not, replace the blown fuse with
another with the same amperage (same
colour).

column will automatically lock
when the key is removed and the
wheels cannot be steered. Also
check that the gearbox/
transmission is in neutral (N).
116) When towing, remember that
the assistance of the brake servo
is absent. Consequently, more
force is required at the pedal
in order to brake. Do not
use flexible cables when towing
and avoid jerky movements. Make
sure not to damage parts in
contact with the car while towing.
When towing the car, you must
comply with all specific traffic
regulations, both in terms of the
towing device and behaviour
on the road. Do not start the
engine while towing the car.
Before tightening the ring, clean
the threaded housing thoroughly.
Make sure that the ring is fully
screwed into the housing before
towing the car.117) The tow hook must be used
exclusively for roadside
assistance operations. You are
allowed to tow the vehicle for
short distances using an
appropriate device in accordance
with the highway code (a rigid
bar), to move the vehicle on the
road in readiness for towing or
transport via a breakdown vehicle.
Tow hooks MUST NOT be used
to tow vehicles off the road or
where there are obstacles and/or
for towing operations using cables
or other non-rigid devices. In
compliance with the above
conditions, towing must take
place with the two vehicles (one
towing, the other towed) aligned
as much as possible along the
same centre line.

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.
