2016 Alfa Romeo 4C inflation pressure

non-existent obstacle ("echo
interference");
the presence of ultrasonic systems
(e.g. pneumatic brake systems of
trucks or pneumatic drills) near the car
could alter the signals sent by the
sensor;
the variation in sensor position,
caused by variation in ride (due to
suspension component wear),
changing tyres, overloaded car, or
tuning that lowers the car, for example,
may affect parking sensor system
performance.
WARNING
45)Parking manoeuvres, however, are
always the driver’s responsibility. While
carrying out these manoeuvres, always
make sure that no people (especially
children) or animals are in the area
concerned. The parking sensors are used
to assist the driver, who must never allow
his attention to lapse during potentially
dangerous manoeuvres, even those
executed at low speeds.
IMPORTANT
4)For correct operation of the system,
sensors must always be clean from mud,
dirt, snow or ice. Be careful not to scratch
or damage the sensors while cleaning
them. Avoid using dry, rough or hard
cloths. The sensors must be washed using
clean water, with the addition of vehicle
shampoo if necessary. When using special
washing equipment such as high pressure
jets or steam cleaning, clean the sensors
very quickly keeping the jet more than 10
cm away. Also, do not apply stickers to the
sensors.
TPMS (Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the car.
Changes in outside temperature may
cause tyre pressure to vary. This means
that a decrease in the outside
temperature corresponds to a decrease
in the tyre pressure.
Tyre pressure must always be adjusted
according to the cold inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the car at a
standstill for at least three hours or a
travel shorter than 1.6 km after an
interval of three hours.
The cold tyre inflation pressure must not
exceed the maximum inflation pressure
value printed on the side of the tyre.
The tyre pressure also increases while
driving the car: this is a normal
condition and does not require any
adjustment of the pressure.
The TPMS continues to advise the
driver of the low tyre pressure condition
until this is corrected; the warning
continues until the pressure
corresponds or exceeds the pressure
prescribed for the cold tyres. When the
50
GETTING TO KNOW YOUR CAR

tyre low pressure control warning lightswitches on constantly, the inflation
pressure must be adjusted until it
reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. You may
need to drive the car for about 20
minutes at a speed higher than 20 km/h
to allow the TPMS to receive this
information.
NOTE
The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
Therefore, the TPMS should not be
used as pressure switch while adjusting
the tyre inflation pressure.
Driving with insufficient tyre pressure
causes their overheating and can result
in tyre failure. The low inflation pressure
reduces fuel efficiency and tyre tread life
and may also affect handling and
braking performance of the car.
The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with a
suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
The TPMS warns the driver of any
condition of insufficient tyre pressure Ifthis drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in all
four tyres are particularly important.

pressure warnings
46) 47) 48) 49) 50) 51) 52) 53) 54)
The system warns the driver if one or
more tyres are flat by the dedicated
warning light
continuously on in the
instrument panel and by displaying
dedicated messages.In this case, stop the car as soon as
possible, check the inflation pressure of
each tyre and inflate to the cold tyre
pressure value prescribed for the car.
The system will automatically update
and after receiving the tyre pressure
update the tyre pressure control
warning light switches off. You may
need to drive the car for about 20
minutes at a speed higher than 20 km/h
to allow the system to receive this
information.TPMS operation faults
The system fault is indicated by the
dedicated warning lightwhich first
flashes for 75 seconds and then stays
on steadily. This can occur in any of the
following situations:
interference caused by electronic
devices or radio frequency emissions
similar to those of the TPM sensors.

WARNING
46)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
wheel.
47)Tyre pressure must be checked with
tyres rested and cold. Should it become
necessary for whatever reason to check
pressure with warm tyres, do not reduce
pressure even though it is higher than the
prescribed value. Repeat the check when
the tyres are cold.
48)Should one or more wheels be fitted
without sensors, the system will no longer
be available and, in addition to the TPMS
warning light flashing for less than one
minute before becoming constant, a
warning message will be shown on the
display, until four wheels with sensors are
fitted again.49)The TPMS cannot warn of sudden
decreases in tyre pressure (for example
when a tyre bursts). In this case, stop the
car, braking with caution and avoiding
abrupt steering.
50)Replacing standard tyres with winter
tyres (and vice versa) requires TPMS
adjustment that must only be performed by
a dedicated Alfa Romeo Dealership.
51)Changes in outside temperature may
cause tyre pressures to vary. The TPMS
system may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.52)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact a dedicated Alfa Romeo
Dealership. Tyre and/or rim fitting/removal
operations require specific precautions; to
avoid damaging or fitting the sensors
incorrectly, tyre and/or rim fitting/removal
operations should only be carried out by
specialised staff. Contact a dedicated Alfa
Romeo Dealership.
53)Intense radio-frequency interference
may prevent the correct operation of the
TPMS. This condition will be indicated by a
message on the display. The message will
disappear automatically as soon as the
radio-frequency interference ceases to
affect the system.

Traffic and road conditions
Rather high consumption levels are
linked to situations with heavy traffic, for
instance when travelling in queues with
frequent use of the lower gears or in
cities with many traffic lights.
Stops in traffic
During prolonged hold-ups (e.g. level
crossings) the engine should be
switched off.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 speedallowed 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.

IN AN EMERGENCY

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.

HEAVY-DUTY USE OF
THE CAR
If the car is used mainly under one of
the following conditions:
if the car is used under demanding
conditions, e.g. on track;
dusty roads;
short, repeated journeys (less than
7–8 km) at sub-zero outside
temperatures;
engine often idling or driving long
distances at low speeds or long periods
of inactivity;
the following checks must be carried
out more often than indicated in the
Scheduled Servicing Plan:
check of front and rear disc brake
pad condition and wear;
check cleanliness of tailgate locks,
cleanliness and lubrication of linkage;
visually inspect conditions of: engine,
gearbox, transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (boots - sleeves -
bushes - etc.);
check battery charge and battery
fluid level (electrolyte);
visually inspect condition of the
accessory drive belts;
check and, if necessary, change
engine oil and replace oil filter;

IMPORTANT
28)Incorrect installation of electric and
electronic devices may cause severe
damage to your car. Contact a dedicated
Alfa Romeo Dealership if you want to install
accessories (anti-theft systems, etc.) after
purchasing the car. They can suggest the
most suitable devices and above all advise
you whether a higher capacity battery
needs to be installed.
IMPORTANT
4)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact a dedicated
Alfa Romeo Dealership.
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. 131:
Anormal pressure: tread evenly worn;
Blow pressure: tread particularly worn
at the edges;
Chigh pressure: tread particularly worn
in the centre.
The tyres must be replaced when the
tread is less than 1.6 mm thick. In anycase, follow the laws in force in the
country where you are driving.
IMPORTANT NOTES
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 vehicle
overloaded. If a tyre is punctured, stop
immediately and change it;
tyres age even if they are not used
much. 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;
in the case of replacement, always
fit new tyres, avoiding those of
