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.

GETTING TO KNOW YOUR CAR

Emergency refuelling
If there is no fuel in the car or the supply
circuit is completely empty, proceed
as follows to reintroduce fuel to the
tank:
❒take the dedicated funnel C fig. 58
from the tool kit located in the
luggage compartment;
❒open flap A, pulling it outwards;
❒insert funnel C in the filler as
illustrated in fig. 58 and refuel;
❒after refuelling, remove the funnel and
close the flap;
❒finally, put the funnel back in its case
and put this back in the luggage
compartment.
IMPORTANT If the filler compartment is
washed with a high-pressure jet, keep
it at a distance of at least 20 cm.
WARNING
55) Do not apply any object/plug to
the end of the filler which is not
provided for the car. The use
of non-compliant objects/plugs
could cause a pressure increase
inside the tank, resulting in
dangerous situations.
56) Do not bring naked flames or lit
cigarettes near to the fuel tank
filler: fire risk. Avoid bringing your
face close to the filler, in order
not to breathe in harmful vapours.
57) Do not use a mobile phone near
the fuel pump: risk of fire.
PROTECTING THE
ENVIRONMENT
The following devices are used for
reducing petrol fuel engine emissions:
catalytic converter, oxygen sensors and
evaporation control system.
Do not let the engine run, even for a
test, with one or more spark plugs
disconnected.
58)
WARNING
58) Under operating conditions, the
catalytic converter becomes very
hot. Therefore, do not park the car
on flammable materials (grass,
dry leaves, pine needles etc.)
to avoid the risk of fire.

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

Warning lights on
displayWhat it means What to do
GENERAL FAILURE
(for versions/markets, where provided)
The symbol lights up in the display in the
circumstances indicated below.
Engine oil pressure sensor failure
The symbol lights up when the engine oil pressure
sensor is faulty. The display shows the dedicated
message.In these case contact the dedicated Alfa Romeo
Dealership to have the fault fixed as soon as
possible.
"Clutch overheating" message
The
symbol, along with a message on the
display, lights up to indicate clutch overheating.
If the driver continues, the
symbol will switch
off and the
warning light will light up (on some
versions together with a message on the display)
to indicate a transmission failure.If the
symbol lights up along with a message
on the display, reduce gear shifting and/or
change usage conditions, until the normal
operating conditions are restored.
If the
warning light lights up (a message will
appear on the display, on some versions) stop
immediately, operate the handbrake, stop the
engine and wait 5 minutes: after this, normal
transmission operating conditions will be
restored.
Should the transmission failure condition persist,
contact the dedicated Alfa Romeo Dealership
FUEL CUT-OFF
The symbol and the corresponding message are
shown on the display in the following cases:
❒fuel cut-off system intervention: the yellow
symbol lights up;
❒fuel cut-off system failure: the red symbol lights
up.For the fuel cut-off system reactivation procedure,
refer to the "Fuel Cut-Off System" section of the
"Controls" paragraph, in the "Knowing your car"
chapter. If it is still not possible to restore the fuel
supply, contact the dedicated Alfa Romeo
Dealership.

❒If it is necessary to proceed downhill
with transmission in neutral (N) for
unexpected reasons, bearing in mind
that this practice is highly inadvisable,
remember that when gear
engagement is requested, the
system will automatically engage the
best gear to permit the correct
transmission of drive torque to the
wheels, according to the speed
of the car.
❒When necessary, it is possible to
engage 1st gear, reverse (R)or
neutral (N) with the engine off, the
key at MAR-ON and the brake
pressed. In this case, change gear
leaving at least 5 seconds between
one gear change and the next, in
order to safeguard the operation of
the hydraulic system, and the pump
in particular.
❒For uphill departures, it is advisable
to accelerate gradually but fully
immediately after releasing the
handbrake or the brake pedal; this
allows the engine to temporarily
increase the number of revs and
tackle the steepest gradients with
more torque at the wheels.
WARNING
89) The Launch control function is
only available in Race mode.
Regardless of what is explicitly
indicated in the description of this
mode, 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.
