2016 Alfa Romeo 4C check engine

inflate the tyre to the pressure
indicated in the “Wheels” paragraph in
the “Technical data” chapter. In order to
obtain a more precise reading, check
the pressure value on pressure gauge B
fig. 85 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 powersocket, 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.

103)The vehicle's driving characteristics
will be modified with the space-saver wheel
fitted. Avoid violent acceleration and
braking, abrupt steering and fast cornering.
The overall duration of the space-saver
wheel is about 3000 km, after which the
relevant tyre must be replaced with another
one of the same type. Never install a
standard tyre on a rim that is designed for
use with a space-saver wheel. Have the
wheel repaired and refitted as soon as
possible. Using two or more space-saver
wheels at the same time is forbidden. Do
not grease the threads of the stud bolts
before fitting them: they might slip out.
104)The jack is a tool developed and
designed only for changing a wheel, if a
tyre gets punctured or damaged, on the
vehicle with which it is supplied or on other
vehicles of the same model. Any other use,
e.g. to jack up other vehicle models or
different things, is strictly prohibited. Never
use it to carry out maintenance or repairs
under the vehicle or to change
summer/winter wheels and vice versa.
Never position yourself under a jacked
vehicle. If any work under the vehicle is
necessary, contact the Alfa Romeo Service
Network. Incorrectly positioning the jack
may cause the vehicle to fall: use it only in
the positions indicated. Do not use the jack
for loads higher than the one shown on its
label. Never start the engine with vehicle
raised. If the vehicle is raised more than
necessary, everything can become more
unstable, with the risk of the vehicle
dropping violently. Thus, lift the vehicle only
as needed in order to access the spare
tyre.
105)The space-saver wheel cannot be
fitted with snow chains.IMPORTANT
14)Contact a dedicated Alfa Romeo
Dealership as soon as possible to have the
correct tightening of the wheel stud bolts
checked.
15)When turning the jack handle make
sure that it can turn freely without scraping
your hand against the ground. The moving
components of the jack ("worm screw" and
joints) can also cause injuries: avoid
touching them. If you come into contact
with lubricating grease, clean yourself
thoroughly.
CHANGING A BULB
16)
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 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.

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. 112 must be intact.
If it is not, replace the blown fuse with
another with the same amperage (same
colour).
110) 111) 112) 113) 114)17)
B = intact fuse;

IMPORTANT
21)The tow hook attachment is only
available at the front end of the car.
WARNING
115)Before towing, turn the key to MAR
and then to STOP without extracting it. The
steering column will automatically lock
when the key is removed and the wheels
cannot be steered. Also check that the
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 vehicle, you must comply
with all specific traffic regulations and
adopt an appropriate driving behaviour. 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 tow truck. 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. 121.
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 level of the oil is close to or below
the MIN mark, add oil via the filler fitting
B fig. 121 until the MAX mark is
reached.
23)
To unscrew and re-tighten the filler cap
it is necessary to use the tool A shown
in fig. 123, found in the car.
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.

WARNING Make sure that the oilcap is tightened properly in its seat
after topping the oil up.
Once the cap has been tightened,
before closing the engine bonnet,
remove the tool A fig. 123and
replace it in its housing to prevent losing
it or damaging the engine.
The range between the MIN and MAX
levels corresponds to approximately 1
litre of oil.
Engine oil consumption
24)3)
The maximum engine oil consumption
is usually 400 grams every 1000 km.
When the car is new, the engine needs
to be 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
122)
The coolant level must be checked
when the engine is cold and must
range between the MIN and MAX
marks on the reservoir.
