2015 Alfa Romeo 4C wheel

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
tyre low pressure control warning
light
switches 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
If this 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.

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 light
which 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.
❒Application of tinted films which
interfere with the signals of the radio
waves.
❒Presence of snow or ice on the
wheels or the wheel arches.
❒Use of snow chains.
❒Use of wheels/tyres not equipped
with TPM sensors.

GETTING TO KNOW YOUR CAR

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 4 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) Strong radio-frequency
interference could inhibit the
regular 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.
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.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
amberTPMSIMPORTANT Do not continue driving with one or
more flat tyres as handling may be
compromised. Stop the car, 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 failure
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.In this case, contact the dedicated Alfa Romeo
Dealership as soon as possible.
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.In any situation in which the message on the
display is "See manual", it is ESSENTIAL to refer
to the contents of the "Wheel" paragraph in the
"Technical data" chapter, strictly complying with
the indications that you find there.

KNOWING THE INSTRUMENT PANEL

Main safety rules to be
followed when carrying
children
❒Follow the instructions supplied with
the child restraint system itself, which
the manufacturer must provide.
Keep the instructions in the car along
with the other documents and this
handbook. Do not use child restraint
systems without instructions;
❒always check that the seat belt is well
fastened by pulling on it;
❒only one child is to be strapped into
each restraint system; never carry
two children using one child restraint
system;
❒always check that seat belts do not
rest on the child’s neck;
❒while travelling, do not let the child sit
incorrectly or release the belts;
❒never carry children on your lap, even
newborns. No-one could restrain
them in the event of an accident;
❒in the event of an accident, replace
the child restraint system with a
new one.FRONT AIRBAGS
DRIVER AND
PASSENGER FRONT
AIRBAGS
The car features multistage front
airbags (“Smart bag system”) for driver
and passenger.
The front driver/passenger airbags are
designed to protect occupants in the
event of frontal impacts of medium-high
severity, by placing the bag between
the occupant and the steering wheel or
dashboard.
Therefore, non-activation of the front
airbags in other types of collisions (side
collisions, rear shunts, rollovers, etc.)
does not indicate a system malfunction.
Airbags are not a replacement of but
complementary to the seat belts, which
you are recommended to always wear.
In the event of impact, those not
wearing a seat belt are projected
forwards and may come into contact
with the bag which is still inflating. The
protection offered by the bag is
compromised in these circumstances.
72)
Front airbags may not activate in the
following situations:❒frontal impacts against highly
deformable objects not involving the
front surface of the car (e.g. wing
collision against guard rail);
❒jamming of the car underneath other
vehicles or protective barriers (e.g.
underneath a truck or a guard rail); in
this case, the bags would offer no
additional protection with respect to
the seat belt and their deployment
would be inappropriate. In these
cases, non-deployment does not
indicate a system malfunction.

Passenger front airbag
This is located in a dedicated
compartment in the dashboard fig. 72.

GENERAL WARNINGS
The front airbags may activate in the
event of sharp impacts to the
underbody of the car (e.g. impact with
steps, pavements, potholes or road
bumps, etc.).
When the airbag deploys it emits a
small amount of dust: the dust is
harmless and does not indicate the
beginning of a fire. The dust may irritate
the skin and eyes however: in this
case, wash with neutral soap
and water.
Airbag checking, repair and
replacement must be carried out at a
dedicated Alfa Romeo Dealership.If the car is scrapped, have the airbag
system deactivated at a dedicated
Alfa Romeo Dealership.
Pretensioners and airbags are deployed
according to different logics on the
basis of the type of collision. Failure to
deploy of one of the devices does
not necessarily indicate a system
malfunction.
77) 78) 79) 80) 81) 82) 83)
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 that
the airbag can inflate freely if
necessary. Do not drive with your
body bent forward. Keep the
backrest in straight position,
resting correctly your back on it.74) Instructions to deactivate the
passenger's front 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 in case
of need (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 and
elbows out of the window.
77) If the
warning light does not
switch on when the key is turned
to MAR-ON, 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.
