BONNET
OPENING
22) 23)
Proceed as follows:
inside the passenger compartment
pull the release lever, fig. 40 or fig. 41;
go to the outside of the car and
position yourself in front of the grille;
lift the bonnet slightly from right to
left as indicated on the unhooking
device's arrow, fig. 42;
raise the bonnet completely: the
operation is facilitated by the presence
of a gas shock absorber which holds it the
all open position.
Do not tamper with the shock absorber
and accompany the bonnet while lifting it.
CLOSING
22) 24)
To close, lower the bonnet to
approximately 16 in (40 centimetres)
from the engine compartment then let it
drop. Make sure that the bonnet is
completely closed and not only fastened
by the locking device by trying to open it.
If it is not perfectly closed, do not try to
press the bonnet down but open it and
repeat the procedure.
IMPORTANT Always check that the
bonnet is closed correctly to prevent it
from opening while the vehicle is
travelling. Since the bonnet is equipped
with a double locking system, one for
each side, you must check that it is closed
on both its side ends.
WARNING
22)Perform these operations only when the
car is stationary.
23)Use both hands to lift the bonnet. Before
lifting, check that the windscreen wiper arms
are not raised from the windscreen or in
operation, that the vehicle is stationary and
that the electric parking brake is engaged.
24)For safety reasons, the bonnet must
always be properly closed while the car is
travelling. Therefore, make sure that the
bonnet is properly closed and that the lock is
engaged. If you discover that the bonnet is
not perfectly closed during travel, stop
immediately and close the bonnet in the
correct manner.

Red warning lights
Warning
lightWhat it means
INSUFFICIENT BRAKE FLUID / ELECTRIC PARKING BRAKE ON
The warning light switches on when the ignition device is brought to ON, but it should switch off after a few seconds.
Low brake fluid level
The warning light turns on when the level of the brake fluid in the reservoir falls below the minimum level, possibly due to a leak in
the circuit.
Go to an Alfa Romeo Dealership to have the system checked as soon as possible.
Electric parking brake on
The warning light switches on when the electric parking brake is engaged.
Release the electric parking brake, then check that the warning light has switched off.
If the warning light stays on, contact an Alfa Romeo Dealership.
IMPORTANT If the car is parked on a gradient of more than 30% and/or the temperature of the brakes is greater than 662 °F
(350 °C), when the parking brake is engaged, the warning light will flash to indicate a potentially unsafe condition.
EBD FAILURE
The simultaneous switching on of the
(red) and(amber) warning lights with the engine on indicates either a failure of the
EBD system or that the system is not available. In this case, the rear wheels may suddenly lock and the vehicle may swerve when
braking sharply.
Drive very carefully to the nearest Alfa Romeo Dealership to have the system inspected immediately.

KNOWING THE INSTRUMENT PANEL

Warning
lightWhat it means
AIRBAG FAILURE
The warning light switches on when the ignition device is brought to ON, but it should switch off after a few seconds. If the warning
light switches on constantly, this indicates a failure in the airbag system.
28) 29)
FRONT SEAT BELTS NOT FASTENED
The warning light switches on constantly if the car is stationary and the driver side or passenger side seat belt, with the passenger
seated, is not fastened. The warning light flashes and a buzzer will sound if the vehicle is in motion and the driver side or passenger
side seat belt, with the passenger seated, is not correctly fastened.
EXCESSIVE ENGINE OIL TEMPERATURE
The warning light switches on in the case of engine oil overheating.
If the problem persists, contact an Alfa Romeo Dealership.
15)
WARNING
28)The fault of thewarning light is signalled by the switching on of theicon on the instrument panel. In this case, the warning light may not
indicate any faults with the restraint systems. Before proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.
29)If the
warning light does not switch on when the ignition device is moved to ON or if it stays on when driving (together with the message on
the display), there might be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked
immediately.
IMPORTANT
15)If the symbol switches on when driving, stop the vehicle and the engine immediately.

Warning
lightWhat it means
FUEL RESERVE / LIMITED RANGE
The warning light (or the icon on the display) turns on when there are about 1.8 UK gal (8 litres) of fuel left in the tank, for Diesel
versions, and about 2 UK gal (9 litres) of fuel for petrol versions.
30)
INJECTION / EOBD SYSTEM FAILURE
In normal conditions, when the ignition device is brought to ON, the warning light switches on, but it should switch off as soon as the
engine is started.
The operation of the warning light may be checked by the traffic police using specific devices. Comply with the laws and
regulations of the country where you are driving.
16)
Injection system failure
If the warning light remains on, or it switches on whilst driving, the injection system is not working properly. The warning light on
constantly signals a malfunction in the supply/ignition system which could cause high exhaust emissions, a possible loss of
performance, poor driveability and high consumption.
The warning light switches off if the malfunction disappears, but is still stored by the system.
Under these conditions, the vehicle can continue travelling at moderate speed but without demanding excessive effort from the
engine or high speed. Prolonged use of the car with the warning light on constantly may cause damage. Contact an Alfa Romeo
Dealership as soon as possible.
Catalytic converter damaged
If the warning light flashes, it means that the catalytic converter may be damaged.
Release the accelerator pedal to lower the speed of the engine until the warning light stops flashing. Continue the journey at
moderate speed, trying to avoid driving conditions that may cause further flashing and contact an Alfa Romeo Dealership as soon
as possible.

KNOWING THE INSTRUMENT PANEL

area by lighting up, on the relevant side,
the warning light located on the door
mirror fig. 59 and, where provided, by
means of an acoustic signal (if the
respective item is programmed on the
Connect system). The default setting is
“Sound and Display”.
When the engine is started the warning
light turns on to signal the driver that the
system is active.
Sensors
57)
The sensors are activated when any
forward gear is engaged at a speed
higher than about 6 mph (10 km/h), or
when reverse is engaged.
The sensors are temporarily deactivated
when the car is stationary and the P
(Park) mode active.
The detection area of the system coversabout a lane on both sides of the car
(around 10 ft (3 metres)).
This area begins from the door mirror and
extends for about 20 ft (6 metres)
towards the rear part of the car.
When the sensors are active the system
monitors the detection areas on both
sides of the car and warns the driver
about the possible presence of cars in
these areas.
While driving the system monitors the
detection area from three different input
points (side, rear and front) to check
whether a signal needs to be sent to the
driver. The system can detect the
presence of a vehicle in one of these
three areas.
IMPORTANT The system does not signal
the presence of fixed object (e.g. safety
barriers, poles, walls, etc.). However, in
some circumstances, the system may
activate in the presence of these objects.
This is normal and does not indicate a
system malfunction.
IMPORTANT The system does not warn
the driver about the presence of vehicles
coming from the opposite direction, in
the adjacent lanes.
Important notes
If a trailer is hitched to the vehicle, the
system automatically deactivates.For the system to operate correctly, the
rear bumper area where the radar
sensors are located must stay free from
snow, ice and dirt gathered from the road
surface.
Do not cover the rear bumper area where
the radar sensors are located with any
object (e.g. adhesives, bike rack, etc.).
If, after purchasing the vehicle, you wish
to install the tow hook, you need to
deactivate the system via the Connect
system. To access the function, on the
main menu select the following items in
sequence: "Settings", "Safety" and "Blind
Spot Alert".
Rear view
The system detects cars coming from the
rear part of your car on both sides and
entering the rear detection area with a
difference in speed of less than 31 mph
(50 km/h) with respect to your car.
Overtaking vehicles
If another vehicle is overtaken slowly
(with a difference in speed of less than
about 15.5 mph (25 km/h) and this stays
in the blind spot for about 1.5 seconds,
the warning light on the door mirror of
the corresponding side lights up.
If the difference in speed between the
two vehicles is greater than about
15.5 mph (25 km/h), the warning light
does not light up.

SAFETY

when that vehicle is at a greater distance,
thus providing the possibility of acting on
the brakes more lightly and gradually.
This setting provides the drivers with the
maximum possible reaction time to
prevent a potential accident.
With the option set to "Near", the system
will warn the driver of a possible accident
with the vehicle in front when that vehicle
is close. This setting offers the driver a
lower reaction time compared to the
"Med" and "Far" settings, in the event of a
potential accident, but permits more
dynamic driving of the car.
The system sensitivity setting is kept in
the memory when the engine is switched
off.
System limited operation warning
If the dedicated message is displayed, a
condition limiting the system operation
may have occurred. The possible reasons
of this limitation are something blocking
the camera view or a fault.
In this condition it will still be possible to
drive the car normally, but automatic
braking will not be available in the event
of an impending collision.
If an obstruction is signalled, clean the
area of the windscreen indicated in
fig. 61.
When the conditions limiting the system
functions end, this will go back to normaland complete operation. Should the fault
persist, contact an Alfa Romeo
Dealership.
System failure warning
If the system switches off and a
dedicated message is shown on the
display, it means that there is a fault on
the system.
In this case, it is still possible to drive the
car, but you are advised to contact an
Alfa Romeo Dealership as soon as
possible.
Radar warning not available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message appears on the display. This
generally occurs in the event of poor
visibility, such as when it is snowing or
raining heavily.
The system can also be temporarily
dimmed due to obstructions such as mud,
dirt or ice on the bumper. In such cases, a
dedicated message will be shown on the
display and the system will be
deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflective
tiles or ice or snow). When the conditions
limiting the system functions end, this
will go back to normal and complete
operation.In certain particular cases, this dedicated
message could be displayed when the
radar is not detecting any vehicles or
objects within its view range.
If atmospheric conditions are not the real
reason behind this message, check if the
sensor is dirty. It could be necessary to
clean or remove any obstructions in the
area shown in fig. 60.
If the message appears often, even in the
absence of atmospheric conditions such
as snow, rain, mud or other obstructions,
contact an Alfa Romeo Dealership for a
sensor alignment check.
In the absence of visible obstructions,
cleaning the radar surface, by manually
removing the decorative cover trim,
could be required. Have this operation
performed at an Alfa Romeo Dealership.
IMPORTANT It is recommended that you
do not install devices, accessories or
aerodynamic attachments in front of the
sensor or darken it in any way, as this can
compromise the correct functioning of
the system.
