ENGINE STOPPING FAILURE
CONDITIONS
When the system is operating, due to comfort, emission control and
safety reasons, the engine does not stop in some conditions, among
which:
❒engine still cold;
❒especially cold outside temperature;
❒battery not sufficiently charged;
❒particulate filter regeneration (DPF) in progress (diesel engines only);
❒driver's door not shut;
❒driver's seat belt not fastened;
❒reverse gear engaged (for example, for parking manoeuvres);
❒for versions equipped with dual zone automatic climate control (for
versions/markets, where provided), if an adequate level of thermal
comfort has not been reached or with MAX-DEF function activation;
❒during the first period of use, to initialise the system.
If the climate comfort is to be favoured, the Start&Stop
system can be deactivated, for a continuous operation of
the climate control system.
ENGINE RESTARTING CONDITIONS
Due to comfort, emission control and safety reasons, the engine can
restart automatically without any action by the driver, under special
conditions, such as:
❒battery not sufficiently charged;
❒reduced braking system vacuum (e.g. if the brake pedal is pressed
repeatedly);
❒car moving (e.g. when driving on roads with a gradient);
❒engine stopping by Start&Stop system for over 3 minutes;
❒for versions equipped with dual zone automatic climate control
system (for versions/markets, where provided), if an adequate level
of thermal comfort has not been reached or MAX-DEF function
activation.
With gear engaged, automatic engine restarting is possible only by
fully depressing the clutch pedal. The driver is informed by the
displaying of a message on the display and - for versions/markets,
where provided - by the flashing of the symbol
.
Notes
If the clutch is not pressed, about 3 minutes after the engine stops, the
engine can be restarted only using the ignition key.
In cases when the engine stops and this is not desired, due for example
to the clutch pedal being released sharply with a gear engaged, if the
Start&Stop system is activated, the engine can be restarted by fully
depressing the clutch pedal or by placing the gear lever in neutral.

SAFETY FUNCTIONS
When the engine is stopped by the Start&Stop system, if the driver
releases his/her seat belt and opens the driver's or passenger's door,
the engine can be restarted only using the ignition key.
The driver is informed by a buzzer and by the flashing of the symbol
on the display; on some versions, a message is displayed as well.
"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
warning light switching
on in the instrument panel and, for versions/markets where provided,
a message and symbol on the display.
In this case, contact Alfa Romeo Authorized Services.
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.
The procedure must be carried out as follows: press button A fig. 82 to
detach connector B from battery status monitoring sensor C (this is
located on the negative pole of the battery itself).
In case of battery replacement, always contact Alfa
Romeo Authorized Services. Replace the battery with
one of the same type (HEAVY DUTY) and with the same
specifications.
IMPORTANT After turning the ignition key to STOP, wait at least 1
minute before disconnecting the electrical supply to the battery.

JUMP STARTING
When jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A fig. 83 of the car battery, but
rather to an engine/gearbox earth point.
Before opening the bonnet, make sure the engine is off and
the ignition key is in the STOP position. Follow the
indications on the plate underneath the bonnet fig. 84. It is
advisable to extract the key when there are other people in the car.
Leave the car only after having removed the ignition key or having
turned it to STOP. During refuelling, make sure that the engine is off
and that the ignition key is in the STOP position.
DYNAMIC SUSPENSION
(active shock absorber system)
(for versions/markets, where provided)
This system interacts with the “Alfa DNA” system (see paragraph “Alfa
DNA”).
The “Alfa DNA” system lever allows you to choose three different
driving settings depending on the route type and on the road surface:
❒d = Dynamic (sports driving mode);
❒n = Natural (mode for driving in normal conditions);
❒a = All Weather (mode for driving in poor grip conditions, such as
rain and snow).

In “Natural” and “All Weather” operating mode, the active shock
absorbers adjust the car suspension to suit the route type and
the driving stresses, thus considerably improving driving comfort in
particular on rough terrain.
The "Dynamic" operating mode produces a sports driving setting
characterised by more responsive acceleration and greater effort on
the steering wheel to give a sporty feeling. The shock absorber
damping action is also adjusted and divided, to guarantee higher
precision and reactivity of the car, while maintaining a good comfort
level.
The car is more precise when entering bends and quicker in changing
direction.EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD system (European On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace damaged components.
The car also has a diagnostic connector that can be interfaced with
appropriate tools, which makes it possible to read the error codes
stored in the electronic control units together with a series of specific
parameters for engine operation and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.

ELECTRIC POWER STEERING
This only operates with the key turned to MAR-ON and the engine
started. Power steering allows the force required at the steering wheel
to be adapted to driving conditions.
The different power assistance modes can be selected via the "d,n,a"
positions of the “Alfa DNA System” lever (see “Alfa DNA System”
paragraph).
It is absolutely forbidden to carry out any after-market
operation involving steering system or steering column
modifications (e.g.: installation of anti-theft device)
that could badly affect performance and safety, invalidate the
warranty and also result in non-compliance of the car with
type-approval requirements.
Before performing any maintenance operations,
always turn off the engine and remove the key from
the ignition to lock the steering column, especially
when the car’s wheels are not touching the ground.
INSTALLING ELECTRICAL/
ELECTRONIC DEVICES
Electrical and electronic devices installed after buying the car in the
context of after-sales service must carry the following label: fig. 85
Fiat Group Automobiles S.p.A. authorises the installation of transceiver
devices on condition that such installations are carried out in a
workmanlike fashion, following the manufacturer’s instructions, at a
specialised centre.
IMPORTANT Traffic police may not allow the car on the road if devices
have been installed which modify the features of the car. This may
also cause invalidation of warranty in relation to faults caused by the
change either directly or indirectly related to it.
Fiat Group Automobiles S.p.A. shall not be liable for damage caused
by the installation of accessories either not supplied or recommended
by Fiat Group Automobiles S.p.A. and/or not installed in compliance
with the provided instructions.

RADIO TRANSMITTERS AND MOBILE
PHONES
Radio transmitter equipment (vehicle mobile phones, CB radios,
amateur radio, etc.) cannot be used inside the car unless a separate
aerial is mounted externally.
IMPORTANT The use of similar devices inside the passenger
compartment (without separate aerial) produces radio-frequency
electromagnetic fields which, amplified by the resonance effects inside
the passenger compartment, may cause electrical systems equipping
the car to malfunction. This could compromise safety in addition to
constituting a potential hazard for the passengers.
In addition, transmission and reception of these devices may be
affected by the shielding effect of the car body.
As far as the use of EC-approved mobile phones is concerned (GSM,
GPRS, UMTS), follow the usage instructions provided by the mobile
phone manufacturer.
PARKING SENSORS
(for versions/markets, where provided)
The parking sensors are located in the car's rear bumper fig. 86 and
their function is to inform the driver, through an intermittent acoustic
signal, about the presence of obstacles behind the car.
ACTIVATION
The sensors are activated by engaging reverse gear. As the obstacle
behind the vehicle gets closer to the car, the acoustic signal becomes
more frequent.

INDICATIONS ON DISPLAY
(for versions/markets, where provided)
When the sensor is activated, the "Reconfigurable multifunction
display" (for versions/markets, where provided) shows the screen
illustrated in fig. 87.
Obstacle presence and distance information is therefore provided both
by the buzzer and the instrument panel display.
If there are several obstacles the closest one is indicated.
ACOUSTIC SIGNAL
When reverse gear is engaged an acoustic signal is automatically
activated if there is an obstacle within the range of operation.
The acoustic signal:
❒increases as the distance between the car and the obstacle
decreases;
❒becomes continuous when the distance between the car and the
obstacle is less than 30 cm and stops immediately if the distance
increases;
❒remains constant if the distance remains unchanged; if this situation
concerns the side sensors, the buzzer will stop after about 3 seconds
to avoid, for example, warning indications in the event of
manoeuvres along walls.
IMPORTANT The volume of the acoustic signal can be adjusted through
the option "Warning volume" of the "Set-Up menu".
Detection distances
❒Central operating range: 140 cm
❒Side operating range: 60 cm
If several obstacles are detected by the sensors, only the nearest one is
considered.

OPERATION WITH TRAILER
Parking sensor operation is deactivated automatically when the trailer
electric cable plug is fitted into the car tow hook socket. The sensors
are automatically enabled again when the trailer's cable plug is
removed.
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 should 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.
When repainting the bumpers or touching up paint in
the sensor area, contact Alfa Romeo Authorized
Services only. Incorrect paint application could affect
the operation of the parking sensors.
Parking manoeuvres however are always the driver’s
responsibility. When carrying out such manoeuvres,
always ensure that the manoeuvring area is free of
people (particularly children) and animals. The parking sensor is
designed to assist drivers, who must still never allow their
attention to lapse during potentially dangerous manoeuvres even
if performed at low speed.
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.
