2014 Alfa Romeo Giulietta sensor

"ENERGY SAVING"
FUNCTION
(for versions/markets, where provided)
If, following automatic engine restarting,
the driver does not carry out any
action on the car for over 3 minutes,
the Start&Stop system stops the engine
once and for all, to prevent fuel
consumption. In these cases, the
engine can be restarted only using the
ignition key.
NOTE In any case, it is possible to keep
the engine running by deactivating the
Start&Stop system.IRREGULAR OPERATION
In the event of malfunction, the
Start&Stop system is deactivated.
The driver is informed of the fault by the
flashing
symbol (versions with
multifunction display) or
symbol
(versions with reconfigurable
multifunction display). For versions/
markets where provided, a message is
also displayed.
In this case, contact an Alfa Romeo
Dealership.CAR INACTIVITY
In the event of car inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection
of the battery power supply.
Proceed as follows: detach connector
A fig. 83 (by pressing button B) from
sensor C for monitoring the status
of the battery installed on the negative
battery pole D. This sensor should
never be disconnected from the pole
except if the battery is replaced.
48)
IMPORTANT After turning the ignition
key to STOP, wait at least 1 minute
before disconnecting the electrical
supply to the battery.83

iTPMS (indirect Tyre
Pressure
Monitoring System)(for versions/markets, where provided)
DESCRIPTION
The car can be equipped with the
iTPMS (indirect Tyre Pressure
Monitoring System) which monitors the
tyre inflation status thanks to wheel
speed sensors.
The system warns the driver if one or
more tyres are flat by the dedicated
warning light
continuously on and a
warning message on the display.
If one tyre only is flat, the system can
indicate its position: it is anyway
recommended to check the pressure
on all four tyres.
This indication is displayed also when
turning the engine off and on again until
the RESET procedure is carried out.RESET PROCEDURE
The iTPMS system needs an initial
"self-learning" phase (with length
depending on the driving style and road
conditions) which starts when the
RESET procedure is carried out.
The Reset procedure must be carried
out:
❒whenever the tyre pressure is
modified;
❒when even only one tyre is changed;
❒when tyres are rotated/inverted;
❒when the space-saver wheel is fitted.
Before carrying out the RESET, inflate
the tyres to the rated pressure values
specified in the inflation pressure table
(see "Wheels" paragraph in the
"Technical specifications" section).
If the RESET is not carried out, in all
above cases, the warning light
may
give false indications on one or more
tyres.To carry out the RESET, with the car
stopped and the ignition key at
MAR-ON, press the button
fig. 86 on
the dashboard for 2 seconds; after
the RESET, the display shows the
message "RESET SAVED", indicating
that the "self-learning" has started.

PARKING SENSORS(for versions/markets, where provided)
These are located in the car's front
bumper fig. 89 and rear bumper fig. 90
and their function is to inform the driver,
through an intermittent acoustic signal,
about the presence of obstacles in
front of and behind the car.ACTIVATION
Version with rear
sensors
On the versions with 4 rear sensors, the
system is activated when the reverse
gear is engaged.
Version with front and
rear sensors
On the versions with 4 front sensors
and 4 rear sensors, the system is
activated when the reverse gear is
engaged or by pressing the button
fig. 91.
When reverse gear is released, the front
and rear sensors remain activated
until a speed of around 15 km/h
is exceeded to allow the parking
manoeuvre to be completed.The system can also be activated by
pressing the button
in the central
tunnel: a LED in the button switches on
when the system is activated.
Every time the ignition key is turned to
MAR-ON the LED on the button
flashes briefly to indicate that the
system is running a diagnosis. The LED
activation should not be understood
as a fault.
The sensors are deactivated by
pressing the button
again or when
a speed of 15 km/h is exceeded: the
LED in the button is off when the
system is not active.

INDICATIONS ON
DISPLAY
(for versions/markets, where provided)
Versions with rear sensors
When the sensor is activated, the
"Reconfigurable multifunction display"
(for versions/markets, where provided)
shows the screen illustrated in fig. 92.
Versions with front and rear sensors
When the sensors are activated, the
screen in fig. 93 appears on the
"Reconfigurable multifunction display".
Obstacle presence and distance
information is therefore provided both
by the buzzer and the indication on the
display.If there are several obstacles, the
closest one is displayed. On the version
with front and rear sensors, the closest
obstacle in the front area and in the
rear area is displayed.
ACOUSTIC SIGNAL
The information concerning the
presence and distance of an obstacle
from the car is transmitted to the driver
by means of acoustic signals from
buzzers installed in the passenger
compartment:
❒in the versions with rear sensors,a
buzzer in the front dashboard area
warns of the presence of obstacles at
rear;❒in the versions with front and rear
sensors, a front buzzer warns of
the presence of obstacles at the front
and a buzzer located at the rear
warns of the presence of obstacles at
the rear. This permits the driver to
perceive the direction (front/rear) of
the obstacles.
Depending on the position of the
obstacle (in front or at the rear) the
sound is emitted by the corresponding
buzzers (front or rear). The obstacle
closest to the car is signalled.
When reverse gear is engaged an
acoustic signal is automatically
activated if there is an obstacle within
the range of operation.
The acoustic signal:
❒increasesas distance between the
car and the obstacle decreases;
❒becomes continuouswhen the
distance between the car and the
obstacle is less that 30 cm and stops
immediately if the distance
increases;
❒is constantif the distance is unvaried;
if this situation occurs for the side
sensors, the signal will stop after
about 3 seconds to avoid, for
example, indications in the event of
manoeuvres alongside walls.92

IMPORTANT The volume of the
acoustic signal can be adjusted through
the option "Warning volume" of the
Setup menu (see paragraph “Menu
Items” in the “Knowing the instrument
panel” section).
OPERATION WITH
TRAILER
Parking sensor operation is deactivated
automatically when the trailer electric
cable plug is fitted into the car tow
hook socket.
11)
The sensors are automatically
reactivated when the trailer's cable plug
is removed.
59) 60)
GENERAL WARNINGS
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
Objects located near the rear of the car
are not detected under certain
circumstances and could therefore
cause damage to the car or be
damaged.
The following conditions may influence
the performance of the parking sensor
system:❒reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to
the presence on the surface of the
sensor of: ice, snow, mud, thick paint
❒the sensors may detect a non-
existent obstacle (echo interference)
due to mechanical interference, for
example when washing the car,
in rain (strong wind), hail;
❒The signals sent by the sensors can
also be altered by the presence of
ultrasonic systems (e.g. pneumatic
brake systems or pneumatic drills)
near the vehicle.
❒sensor performance can also be
influenced by the position of the
sensors. For example by a change in
the ride setting (caused by the wear
of the shock absorbers, suspension),
overloading the vehicle and carrying
out specific tuning operations that
require the vehicle to be lowered;
❒The detection of obstacles at the top
part of the car may not be
guaranteed because the system
detects obstacles that could cause
an impact with the car in the bottom
part.
IMPORTANT
11) The sensors must be clean of
mud, dirt, snow and ice in order
for the system to work. 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 car 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.
WARNING
59) Only have the bumpers repainted
or any retouches to the paintwork
in the area of the sensors carried
out by an Alfa Romeo Dealership.
Incorrect paint application could
affect the operation of the parking
sensors.

GETTING TO KNOW YOUR CAR

60) Parking and other dangerous
manoeuvres are, however, 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 an aid for the
driver, but the driver must never
allow their attention to lapse
during potentially dangerous
manoeuvres, even those executed
at low speeds.
REFUELLING THE
CARStop the engine before refuelling.
PETROL ENGINES
Only use unleaded petrol 95 R.O.N.
compliant with the European
specification EN228. The petrol octane
rating (R.O.N.) must not be lower than
95. In order to prevent damage to
the catalytic converter never introduce
even the smallest amount of leaded
petrol, even in the event of an
emergency.
DIESEL ENGINES
Use only diesel fuel compliant with
European specification EN590. The use
of other products or mixtures may
damage the engine beyond repair and
consequently invalidate the warranty,
due to the damage caused.Operation at low
temperatures
If the outside temperature is very low,
the diesel thickens due to the formation
of paraffin clots with consequent
defective operation of the fuel supply
system.
In order to avoid these problems,
different types of diesel are distributed
according to the season: summer type,
winter type and arctic type (cold,
mountain areas).
If refuelling with diesel whose
specifications are not suitable for the
usage temperature, it is advisable
to mix TUTELA DIESEL ART additive in
the proportions shown on the container
with the fuel. Pour the additive into
the tank before the fuel.
When using or parking the car for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available fuel. In this case, it is
also advisable to keep the tank over
50% full.

PROTECTING THE
ENVIRONMENTThe following devices are used for
reducing petrol fuel engine emissions:
catalytic converter, oxygen sensors and
evaporation control system
The following devices are used for
reducing diesel fuel engine emissions:
oxidising catalytic converter, exhaust
gas recirculation system (EGR) and
particulate filter (DPF).
62)
DIESEL PARTICULATE
FILTER (DPF)
(Diesel Particulate Filter)
(for versions/markets, where provided)
The Diesel Particulate Filter is a
mechanical filter, integral to the exhaust
system, that physically traps carbon
particles present in the exhaust gases
of diesel engines.
The diesel particulate filter is needed to
eliminate almost all carbon particle
emissions in compliance with
current/future regulations and
standards.During standard use of the vehicle, the
engine control unit records a set of data
(e.g.: travel time, type of route,
temperatures, etc.) and it will then
calculate how much particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be periodically
regenerated (cleaned) at regular
intervals by burning carbon particles.
The regeneration procedure is
controlled automatically by the engine
management control unit according
to the filter conditions and vehicle use
conditions.
During the regeneration there may be a
limited increase in the engine idle
speed, fan activation, a limited increase
in fumes and high temperatures at the
exhaust.
These are not faults; they do not impair
normal car performance or damage
the environment. If the dedicated
message is displayed, see contents of
"Warning lights and messages"
paragraph, in chapter "Knowing the
instrument panel".
WARNING
62) The catalytic converter and
particulate filter (DPF) reach very
high temperatures during
operation. Therefore do not park
the car on flammable materials
(e.g. grass, dry leaves, pine
needles, etc.): fire hazard.
