KNOWING THE INSTRUMENT PANEL

33)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce the
pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on the
current road conditions.
34)To obtain the maximum efficiency of the
braking system, a bedding-in period of about
500 km is needed: during this period it is
better to avoid sharp, repeated and
prolonged braking.
35)If the ABS intervenes, this indicates that
the grip of the tyres on the road is nearing its
limit: you must slow down to a speed
compatible with the available grip.
36)The ABS cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
37)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
38)The capability of the ABS must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
39)For the correct operation of the ABS, the
tyres must of necessity be the same make
and type on all wheels, in perfect condition
and, above all, of the prescribed type and
dimensions.
40)The ASR cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
41)The ASR system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.42)The capability of the ASR must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
43)The HBA system can’t overrule the
natural laws of physics, and can’t increase
the grip available according to the condition
of the road.
44)The HBA system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
45)The features of the HBA system must
never be tested in imprudent or dangerous
ways, with the possibility of putting the
safety of the driver, occupants or other road
users at risk.
46)DST is an aid for driving and does not
relieve the driver of responsibility for driving
the vehicle.iTPMS System (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 in any case
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 needs an initial "self-learning"
phase (with length depending on the
driving style and road conditions: optimal
conditions being driving on a straight
road at 80 km/h for at least 20 minutes)
which starts when the RESET procedure
is carried out.
The Reset procedure must be carried out:
each time tyre pressure is modified;
when even only one tyre is changed;
when tyres are rotated/inverted;
62
SAFETY

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.
OPERATION WITH A TRAILER
Parking sensor operation is automatically
turned off when the trailer electric cable
plug is fitted into the car tow hook
socket.
31)
The sensors are automatically
reactivated when the trailer's cable plug
is removed.
101) 102)
IMPORTANT NOTES
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
Objects set close to the car rear, under
certain circumstances are not detectedand could therefore cause damage to the
car or be damaged.
The following conditions may influence
the performance of the parking
assistance 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
car and carrying out specific tuning
operations that require the car 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
31)The sensor must be free of mud, dirt,
snow or 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 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.
WARNING
101)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.
102)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.
93

132)The cooling system is pressurised. If
necessary, only replace the plug with
another original or the operation of the
system may be adversely affected. Do not
remove the reservoir plug when the engine is
hot: you risk scalding yourself.
133)Do not travel with the windscreen
washer fluid reservoir empty: the
windscreen washer is essential for
improving visibility. Repeated operation of
the system without fluid could damage or
cause rapid deterioration of some system
components.
134)Some commercial additives for
windscreen washer fluid are flammable. The
engine compartment contains hot
components which may start a fire.
135)Brake fluid is poisonous and highly
corrosive. In the event of accidental contact,
immediately wash the affected parts with
water and mild soap. Then rinse thoroughly.
Call a doctor immediately if swallowed.
136)The symbol
, on the brake fluid
container indicates if a brake fluid is
synthetic or mineral-based. Use of mineral
type fluids will damage the special rubber
seals of the braking system beyond repair.
IMPORTANT
3)Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters, we
advise you to contact an Alfa Romeo
Dealership.
4)Used transmission fluid contains
substances that are harmful to the
environment. You are advised to contact an
Alfa Romeo Dealership for oil changes.
BATTERY RECHARGING
IMPORTANT The battery recharging
procedure is given as information only. To
carry out this operation contact an Alfa
Romeo Dealership.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver's side door, wait at least one
minute before disconnecting and then
reconnecting the electrical supply to the
battery.
Charging should be slow at a low ampere
rating for approximately 24 hours.
Charging for a longer time may damage
the battery.
IMPORTANT The cables of the electrical
system must be correctly reconnected to
the battery, i.e. the positive cable (+) to
the positive terminal and the negative
cable (–) to the negative terminal. The
battery terminals are marked with the
positive (+) and negative (–) symbols, and
are shown on the battery cover. The
battery terminals must also be
corrosion-free and firmly secured to the
terminals. If a "quick-type" battery
charger is used with the battery fitted on
the vehicle, before connecting it
disconnect both cables of the battery
itself. Do not use a "quick-type" battery
charger to provide the starting voltage.The cables of the electrical system must
be correctly reconnected to the battery,
i.e. the positive cable (+) to the positive
terminal and the negative cable (–) to the
negative terminal. The battery terminals
are marked with the positive (+) and
negative (–) symbols, and are shown on
the battery cover. The battery terminals
must also be corrosion-free and firmly
secured to the terminals.
