Amber warning lights
Warning
lightWhat it means
ABS FAILURE
The warning light switches on when the ignition device is brought to ON, but it should switch off after a few seconds.
The warning light switches on to indicate an ABS fault. In this case the braking system maintains its efficiency unaltered but
without the advantage of the ABS system.
Drive carefully and contact an Alfa Romeo Dealership as soon as possible.
TPMS FAILURE
The warning light switches on when a failure 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.
Do not continue driving with one or more flat tyres as handling may be compromised. Stop the vehicle, avoiding sharp braking and
steering. Immediately restore the correct inflation pressure using the Tire Repair Kit (see "Repairing a wheel" paragraph in the "In
an emergency" chapter) and contact the dedicated Alfa Romeo Dealership as soon as possible.
Tyre pressure low
The warning light switches on to indicate that the tyre pressure is lower than the recommended value and/or that slow pressure
loss is occurring. In these cases, optimal tyre duration and fuel consumption may not be guaranteed.
In any situation in which the message on the display is "See manual", it is ESSENTIAL to refer to the contents of the "Wheels and
rims" paragraph in the "Technical data" chapter, strictly complying with the indications that you find there.
ESC SYSTEM
When the ignition device is brought to ON, the warning light switches on, but should switch off as soon as the engine is started.
ESC system intervention: Intervention by the system is indicated by the flashing of the warning light: it indicates that the car is in
critical stability and grip conditions.
ECS system failure: If the warning light does not switch off, or if it stays on with the engine running, a failure was found in the ESC
system.
In these cases, contact an Alfa Romeo Dealership as soon as possible.
Hill Start Assist system failure: the switching on of the warning light indicates a Hill Start Assist system failure.
In these cases, contact an Alfa Romeo Dealership as soon as possible.
PARTIAL / TOTAL DEACTIVATION OF ACTIVE SAFETY SYSTEMS (where present)
When the ignition device is brought to ON, the warning light switches on, but should switch off as soon as the engine is started.
The warning light switches on to indicate that some active safety systems have been partially or totally deactivated.
For further details about the active safety systems see the "Active safety systems" paragraph in the "Safety" chapter. When the
active safety systems are reactivated, the warning light switches off.

KNOWING THE INSTRUMENT PANEL

TPMS (Tyre Pressure Monitoring
System)
63) 64) 65) 66) 67) 68) 69)
31)
The car is equipped with Tyre Pressure
Monitoring System (TPMS), which can
advise the driver in the event of
insufficient tyre pressure on the basis of
the pressure when cold indicated in the
"Technical specifications" chapter.
The system comprises a radio-frequency
transmitter sensor fitted to each wheel
(on the rim inside the tyre), which is able
to send information on the inflation
pressure of each tyre to the control unit
fig. 67.
Inflation pressure varies in relation to
temperature by about 1 psi (0.07) bar
every 43.7 °F (6.5 °C). This means that
when the outdoor temperature falls, the
tyre pressure decreases. Always adjustthe tyre inflation pressure when cold.
This is defined as the tyre pressure after
at least 3 hours of vehicle inactivity or
travel of less than 1mile (1.6 km) after
the 3 hour interval.
The cold tyre inflation pressure must not
exceed the maximum pressure indicated
on the shoulder of the tyre: for further
details see the instructions in the "Rims
and tyres" paragraph, in the "Technical
data" chapter.
Tyre pressure increases when the car is
driven. This is normal, and no adjustment
of the pressure is required.
The TPMS signals the driver a possible
insufficient pressure if this falls below
the warning limit for any reason, including
the effects of low temperature and
normal loss of pressure from the tyre.
The TPMS will stop indicating insufficient
tyre pressure when it is equal to or
greater than the prescribed cold inflation
pressure. Therefore, if insufficient tyre
pressure is indicated (
warning light
on instrument panel on), increase the
inflation pressure up to the prescribed
cold inflation value.
The system automatically updates and
warning light
switches off each time
the system receives the updated
inflation pressures. The vehicle might
need to be driven at a speed higher thanabout 15.5 mph (25 km/h) up to
20 minutes for the TPMS to receive this
information.
Operating example
Supposing that the prescribed cold
inflation pressure (i.e. vehicle stationary
for at least 3 hours) is 33.4 psi (2.3 bar),
if the ambient temperature is 68°F
(20°C) and the detected tyre pressure is
28.3 psi (1.95 bar), a temperature
reduction of 19.4°F (−7°C) results in a
decrease in tyre pressure, bringing it to
approximately 24 psi (1.65 bar). This
pressure is sufficiently low to activate
the
warning light.
Heating of tyres due to driving the
vehicle may increase tyre pressure up to
approximately 28.3 psi (1.95 bar), but
the
warning light will stay on. In this
situation, the warning light will switch off
only after the tyres are inflated to the
prescribed cold pressure value for the
car.
IMPORTANT The TPMS is designed for
original tyres and wheels. The prescribed
pressures and consequent alarm
thresholds set in the TPMS are based on
the dimensions of the tyres fitted on the
vehicle. Using spare wheels of a size, type
and/or design different from the original
ones may cause an irregular operation of
the system and damage the sensors.
Aftermarket fitted wheels may damage

82
SAFETY

the sensors. Using aftermarket tyre
sealants may damage the Tyre Pressure
Monitoring System (TPMS) sensor. If
aftermarket tyre sealant is used it is
recommended to go to an Alfa Romeo
Dealership to have the sensors checked.
After checking or adjusting the tyre
inflation pressure, always refit the valve
cap to prevent humidity and dirt from
entering, these may damage the Tyre
Pressure Monitoring System sensor.
LOW TYRE PRESSURE WARNING
If an insufficient pressure value is
detected on one or more tyres, the
warning light on the instrument panel
switches on and the dedicated messages
are shown on the display. The system also
highlights the tyre or tyres with
insufficient pressure graphically. An
acoustic warning is also emitted.
In this case, stop the car, check the
inflation pressure of each tyre and inflate
them to the correct cold inflation
pressure value, shown on the display or in
the dedicated TPMS menu.TPMS TEMPORARILY DISABLED
TPMS check message
If a system failure is present, the
warning light flashes for about
75 seconds and then stays on solid. An
acoustic warning is also emitted.
A dedicated message and dashes "– –"
instead of the pressure value are shown
on the display, to indicate that detection
is impossible.
When the ignition device is set to STOP
and then back to ON, the indication
sequence repeats provided that the
failure is still resent.
The
warning light switches off when
the failure condition disappears and the
pressure value is displayed again in place
of the dashes.
A fault in the system could occur in the
following cases:
intense radio-frequency interference
may prevent the correct operation of the
TPMS. This condition will be indicated by
a dedicated message on the display. The
warning will disappear automatically as
soon as the radio-frequency interference
ceases to affect the system;
aftermarket application of coloured
films on the windows that interfere with
the radio waves emitted by the TPMS;
accumulation of layers of snow or ice
on the wheels or the wheel arches;
using snow chains;
using a rim/tyre assembly without
sensors for the TPMS system.
After the punctured tyre has been
repaired with the original tyre sealant
contained in the TireKit, the previous
condition must be restored, so that the
warning light is off during normal
driving.
Deactivating TPMS messages
(for markets where provided)
When replacing the standard wheels with
others that do not have TPMS sensors
(for example when substituting the
rim/tyre assembly for the winter season)
and depending on the country of sale, the
messages only can be disabled
automatically at the next start-up after
the fault.
The TPMS will emit an acoustic warning,
the
warning light will flash for about
75 seconds, then it will stay on
continuously and the instrument panel
will display the "TPMS check" message
with dashes (– –) instead of the pressure
values on the Connect system display.
From the following ignition cycle, the
TPMS will not emit any acoustic warning
and the display will not show the
message "TPMS check", but the dashes
will be still displayed instead of the
pressure value.
The system will only resume normal
83

operation when all the pressure sensors
have been detected again.
IMPORTANT If wheels without pressure
sensors (e.g. wheels with winter tyres)
have been installed on the vehicle and the
standard wheels (with sensors) are
stored close the vehicle, the system
could detect the pressures of the latter
and consequently display the fault cycle
again once its has left the sensitive area.
WARNING
57)The system is an aid for vehicle driving,
it DOES NOT warn the driver about incoming
vehicles outside of the detection areas. The
driver must always maintain a sufficient
level of attention to the traffic and road
conditions and for controlling the trajectory
of the vehicle.
58)The Forward Collision Warning (FCW)
system is automatically deactivated when
RACE mode is selected.
59)The system is an aid for the driver, who
must always pay full attention while driving.
The responsibility always rests with the
driver, who must take into account the
traffic conditions in order to drive in
complete safety. The driver must always
maintain a safe distance from the vehicle in
front.
60)If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).61)The system intervenes on vehicles
travelling in the same lane. People, animals
and things (e.g. pushchairs) are not taken
into consideration.
62)If the car must be placed on a roller
bench for maintenance interventions or if it
is washed in an automatic roller washing
tunnel with an obstacle in the front part (e.g.
another car, a wall or another obstacle), the
system may detect its presence and
activate. In this case the system must be
deactivated through the settings of the
Connect system.
63)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
tyre, and correct maintenance: the system is
not used to signalling a possible tyre fault.
64)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.
65)Should one or more wheels be fitted
without sensors, the system will no longer be
available and a warning message will be
shown on the display, until wheels with
sensors are fitted again.
66)The TPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In this
case, stop the vehicle, braking with caution
and avoiding abrupt steering.
67)Changes in outside temperature may
cause tyre pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.68)Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed by
Alfa Romeo Dealerships.
69)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact an Alfa Romeo Dealership. The
fitting/removal of the tyres and/or rims
require special care. To avoid damaging or
fitting the sensors incorrectly, tyre and/or
rim fitting/removal operations should only
be carried out by specialised staff. Contact
an Alfa Romeo Dealership.
IMPORTANT
22)The system may have limited or absent
operation due to weather conditions such as:
heavy rain, hail, thick fog, heavy snow.
23)The section of the bumper before the
sensor must not be covered with adhesives,
auxiliary headlights or any other object.
24)System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle.
25)Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front geometry,
tyre change, or a heavier load than the
standard load of the vehicle.
26)Incorrect repairs made on the front part
of the vehicle (e.g. bumper, chassis) may alter
the position of the radar sensor, and
adversely affect its operation. Go to an Alfa
Romeo Dealership for any operation of this
type.

disconnected.
135)Contact an Alfa Romeo Dealership if a
safety system (airbags, brakes),
transmission system (engine, gearbox) or
steering system general protection fuse
blows.
136)If a fuse blows again, contact an Alfa
Romeo Dealership.
137)If a general protective fuse
(MAXI-FUSE, MEGA-FUSE, MIDI-FUSE)
blows, contact an Alfa Romeo Dealership.
IMPORTANT
60)Never replace a fuse with metal wires or
anything else.
61)If it is necessary to wash the engine

if after 15 minutes pressure is not at
least 26 psi (1.8 bar), disengage the
compressor from the valve and power
socket, then move the car forwards
approx. five wheel turns 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 26 psi (1.8 bar) within
15 minutes from the compressor
switching on, do not drive off and contact
an Alfa Romeo Dealership;
after having driven for about 5 miles
(8 km), stop, engage the electric parking
brake and recheck the tyre pressure;
if the pressure is less than 26 psi
(1.8 bar), do not go back into gear but see
an Alfa Romeo dealer;
if a pressure value of at least 26 psi
(1.8 bar) is detected, restore the correct
pressure (with engine running and
electric parking brake), resume driving
immediately and drive with great care to
an Alfa Romeo Dealership.
SEALANT BOTTLE REPLACEMENT
IMPORTANT Only use original cartridges,
which can be purchased at an Alfa Romeo
dealership.
Proceed as follows:

IN AN EMERGENCY

SCHEDULED SERVICING
Correct servicing is crucial for
guaranteeing a long life for the vehicle
under the best conditions.
For this reason, Alfa Romeo has planned
a series of checks and maintenance
operations at fixed distance intervals
and, for versions/markets, where
provided, at fixed time intervals, as
described in the Service Schedule.
Before each service, it is always
necessary to carefully follow the
instructions in the Scheduled Servicing
Plan (e.g. periodically check level of
fluids, tyre pressure, etc.).
Scheduled Servicing is offered by an Alfa
Romeo Dealership according to a set
time schedule. If, during each operation,
in addition to the ones scheduled, the
need arises for further replacements or
repairs, these may be carried out with the
owner's explicit consent only.
IMPORTANT Scheduled Servicing
operations are required by the
Manufacturer. Failure to have them
carried out may invalidate the warranty.
It is advisable to inform the Alfa Romeo
Dealership of any small operating
irregularities without waiting for the next
service.
REGULAR CHECKS
Every year or620miles (1,000km) or
before long journeys, check and top up, if
necessary:
engine coolant level;
brake fluid level (if insufficient, see an
Alfa Romeo dealership as soon as
possible);
low AdBlue diesel emissions additive
(UREA) level warning (2.2 JTD versions
only);

SERVICING AND CARE

WHEELS AND TYRES
171) 172) 173)
Before embarking on a long trip, and
every two weeks, check the tyre inflation
pressure. Check the tyres when cold.
SNOW CHAINS
81)
Rear Wheel Drive and All-wheel drive
versions
0.28 inch (7 mm) snow chains can be used
on all tyres. For tyres up to 8.86 in
(225 mm) in width (205/60R16,
225/55R16, 225/50R17, 225/45R18),
it is also possible to install 0.35 in (9 mm)
chains.
Important notes
The use of snow chains should be in
compliance with local regulations of each
country. In certain countries, tyres
marked with code M+S (Mud and Snow)
are considered as winter equipment;
therefore their use is equivalent to that
of the snow chains.
The snow chains may be applied only to
the rear wheel tyres.
Check the tension of the snow chains
after the first few metres have been
driven.
IMPORTANT Using snow chains with
tyres with non-original dimensions may
damage the vehicle.
IMPORTANT Using different size or type
(M+S, snow, etc.) tyres between front and
rear axle may adversely affect car
driveability, with the risk of losing control
of the car and resulting accidents.
SUGGESTIONS ABOUT THE ROTATION
OF THE TYRES
The front and rear tyres are subject to
different loads and stress due to
steering, manoeuvres and braking. For
this reason they are subject to uneven
wear.
To resolve this problem, tyres should be
rotated at the appropriate time (6200 /
9300 miles (10000 / 15000 km)).
Inverting the tyres means moving them
to different positions on the same side of
the car (front to back and vice versa).
IMPORTANT Crossing the tyres is not
advised, so placing a tyre on a different
axle on the other side of the car is
impossible.
IMPORTANT On cars equipped with
differentiated tyres (tyre size different
between front and rear axles, ex. QV
version) rotation of any of the tyres is not
advised.
Tyre rotation contributes to the
preservation of the grip and tractionperformance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting an Alfa Romeo
Dealership.
All Wheel Drive (AWD) versions
It is recommended to avoid situations
with a large difference in wear between
the front and rear tyres and to strictly
use winter tyres of the sizes given in the
“Rims and tyres provided” table.
The AWD systems and the original tyres
were developed together to ensure the
vehicle’s best performance. When
changing the tyres, it is therefore
recommended to use the same “AR”
marked tyres, to maintain the same level
of performance and component life.
WARNING
171)The road holding qualities of the car
also depend on the correct inflation pressure
of the tyres.
172)If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
173)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
177

COLD TYRE INFLATION PRESSURE
When the tyres are warm, the inflation pressure should be +4.35 psi (+0.3 bar) in relation to the recommended figure. However,
recheck that the value is correct with the tyre cold.
If it is necessary to raise the vehicle, refer to the "Raising the vehicle" paragraph in the "In an emergency" chapter.
The pressures given below apply to all tyre types: summer, winter and all season (where provided).
