KNOWING YOUR CAR

Move the stalk upwards (unstable
position) to activate the MIST function:
operation is limited to the time for which
the stalk is held in this position. When
released, the stalk will return to its
default position and the windscreen
wiper will be automatically stopped. This
function is useful to remove small
deposits of dust from the windscreen, or
morning dew.
IMPORTANT This function does not
activate the windscreen washer;
windscreen washer fluid will not
therefore be sprayed onto the
windscreen. To spray windscreen washer
fluid onto the windscreen, the washing
function must be used.
With ring nut in position
or, the
windscreen wiper will automatically
adapt its operating speed to the speed of
the vehicle.“Smart washing” function
Pull the stalk towards the steering wheel
(unstable position) to operate the
windscreen washer.
Keep the stalk pulled to activate both the
windscreen washer jet and the
windscreen wiper with a single
movement; the latter turns on
automatically.
The windscreen wiper stops working
three strokes after the stalk is released.
A further stroke after approx. 6 seconds
completes the wiping cycle.
RAIN SENSOR
This is located behind the interior rear
view mirror, in contact with the
windscreen and can detect the presence
of rain and, consequently, manage the
cleaning of the windscreen in accordance
with the amount of water on the screen.
Activation/deactivation
9) 10)
Rotating the ring nut fig. 34 to position
oractivates the rain sensor.
The activation of the sensor is signalled
by a flick of the wiper (indicating that the
command has been acquired).
To deactivate the system, use ring nut
fig. 34 or turn the ignition device to STOP.
If the ignition device is moved to STOP
position, leaving the ring nut fig. 34 in
or, when the vehicle is next
started (ignition device at ON), no wiping
cycle occurs even if it rains.
19)
WARNING
19)Make sure the device is switched off
whenever the windscreen must be cleaned.
IMPORTANT
7)Never use the windscreen wipers to
remove layers of snow or ice from the
windscreen. In such conditions, the
windscreen wiper may be subjected to
excessive stress and the motor cut-out
switch, which prevents operation for a few
seconds, may intervene. If operation is not
subsequently restored, even after restarting
the engine, contact an Alfa Romeo
Dealership.
8)Do not operate the windscreen wiper with
the blades lifted from the windscreen.
9)Do not activate the rain sensor when
washing the car in an automatic car wash.
10)Make sure the device is switched off if
there is ice on the windscreen.

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.

Contact an Alfa Romeo Dealership to have the system checked.
POSSIBLE ICE ON ROAD
The symbol turns on when the outside temperature falls to or below 37°F (3°C).
ENGINE OIL DETERIORATED
(where provided)
The symbol is displayed only for a limited time.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on as described above
until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is now necessary to
change the oil as a result of regular use of the vehicle. The deterioration of engine oil is accelerated by using the vehicle for short
drives, preventing the engine from reaching operating temperature.
Contact an Alfa Romeo Dealership as soon as possible.
17)
IMPORTANT
17)Deteriorated engine oil should be replaced as soon as possible after the symbol is switched on, and never more than 500 km after it first
switches on. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. When this symbol comes on, it
does not mean that the level of engine oil is low, so if it flashes you do not need to top up the engine oil.

KNOWING THE INSTRUMENT PANEL

ACTIVE SAFETYSYSTEMS
The vehicle may be equipped with the
following active safety devices:
ABS (Anti-Lock Brakes);
DTC (Drive Train Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
AST (Alfa™ Steering Torque);
ATV (Alfa™ Active Torque Vectoring).
For the operation of the systems, see the
following pages.
ABS (Anti-lock Braking System)
This system, which is an integral part of
the braking system, prevents one or more
wheels from locking and slipping in all
road surface conditions, irrespective of
the intensity of the braking action,
ensuring that the vehicle can be
controlled even during emergency
braking and optimising stopping
distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may be
more frequent.
The system also improves control and
stability of the vehicle when braking on a
surface where the grip of the left and
right wheels varies, or on corners.The Electronic Braking Force Distribution
(EBD) system completes the system
allowing the brake force to be distributed
between the front and rear wheels.
System intervention
The ABS equipped on this vehicle is
provided with the "Brake by wire"
(Integrated Brake System - IBS) function.
With this system, the brake pedal command
given by pressing the brake pedal is not
transmitted hydraulically but electronically,
therefore, the light pulsation that could be
felt on the pedal with the traditional system
is no longer perceptible.
30) 31) 32) 33) 34) 35)
DTC (Drive Train Control)SYSTEM(where provided)
Some versions of this vehicle are
equipped with a four-wheel drive system
(AWD), activated on request, which offers
an optimal drive for countless driving
conditions and road surfaces. The system
reduces the slipping of the tyres to a
minimum, automatically redistributing
the torque to the front and rear wheels,
as needed.
To maximize fuel savings, the vehicle with
AWD automatically passes to rear
four-wheel drive (RWD) when the road
and environmental conditions are such
that they wouldn't cause the tyres to slip.
When the road and environmentalconditions require better traction, the
vehicle automatically goes to AWD mode.
36)
The driving mode, RWD or AWD, is shown
on the instrument panel display.
IMPORTANT If the system failure symbol
switches on, after starting the engine or
while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently, it
is recommended to carry out the
maintenance operations.
37)
ESC (Electronic Stability Control)
SYSTEM
The ESC system improves the directional
control and stability of the car in various
driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
vehicle’s understeer or oversteer.
66
SAFETY

47)The capability of the TC must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
48)The PBA system cannot overrule the
natural laws of physics, and cannot increase
the grip available according to the condition
of the road.
49)The PBA system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
50)The capability of the PBA system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
the safety of the driver, the other occupants
of the vehicle or any other road user.
51)The HSA system is not a parking brake;
therefore, never leave the vehicle without
having engaged the electric parking brake,
turned the engine off and engaged first gear,
so that it is parked in safe conditions.
52)There may be situations on small
gradients (less than 8%), with vehicle laden,
in which the Hill Start Assist system may not
activate, causing a slight reversing motion
and increasing the risk of collision with
another vehicle or object. The driver is, in any
case, responsible for safe driving.
53)The AST system is an aid for driving and
does not relieve the driver of responsibility
for driving the vehicle.DRIVING ASSISTANCE
SYSTEMS
The vehicle can feature the following
driving assistance systems:
BSM (Blind Spot Monitoring);
FCW (Forward Collision Warning);
TPMS (Tyre Pressure Monitoring
System).
For the operation of the systems, see the
following pages.
BSM (Blind Spot Monitoring)SYSTEM
The BSM (Blind Spot Monitoring) system
uses two radar sensors, located in the
rear bumper (one for each side - see
fig. 66 ), to detect the presence of
vehicles (vehicles, trucks, motorbikes,
etc.) in the rear side blind spots of your
vehicle.
The system warns the driver about the
presence of vehicles in the detectionarea by lighting up, on the relevant side,
the warning light located on the door
mirror fig. 67.
When the engine is started the warning
light turns on to signal the driver that the
system is active.
Sensors
54)
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 vehicle is stationary and the P
(Park) mode active.
The detection area of the system covers
about a lane on both sides of the vehicle
(around 10 ft (3 m)).
This area begins from the door mirror and
6606016S0001EM
6706016S0002EM
69

extends for about 20 ft (6 m) towards the
rear part of the vehicle.
When the sensors are active the system
monitors the detection areas on both
sides of the vehicle and warns the driver
about the possible presence of vehicles
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 radarsensors 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 vehicles coming from
the rear part of your vehicle on both sides
and entering the rear detection area with
a difference in speed of less than 30 mph
(50 km/h) with respect to your vehicle.
Overtaking vehicles
If another vehicle is overtaken slowly
(with a difference in speed of less than
about 15 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 mph (25 km/h), the warning light does
not light up.RCP (Rear Cross Path detection) system
This system helps the driver during
reverse manoeuvres in the case of
reduced visibility.
The RCP system monitors the rear
detection areas on both sides of the
vehicle, to detect objects moving
towards the sides of the vehicle at a
minimum speed between about 0.6 mph
(1 km/h) and 2 mph (3 km/h) and objects
moving at a maximum speed of 22 mph
(35 km/h), as generally happens in
parking areas.
The system activation is signalled to the
driver by means of a visual and acoustic
warning.
IMPORTANT If the sensors are covered
by objects or vehicles, the system will not
warn the driver.
Operating mode
The system may be activated/
deactivated via the Connect system. To
access the function, on the main menu
select the following items in sequence:
"Settings", "Safety" and "Blind Spot
Alert".
"Blind spot alert", "Visual" mode
When the system is enabled, a visual
warning is sent to the door mirror on the
side of the detected object.
The visual warning on the mirror will blink
if the driver switches on the direction
70
SAFETY

Radar indication 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. 68.
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.
Frontal collision alarm with active
braking
(where provided)
If this function is selected, the brakes are
operated to reduce the speed of the
vehicle in the event of potential frontal
impact.
This function applies an additional
braking pressure if the braking pressure
applied by the driver does not suffice to
prevent potential frontal impact.
The function is active with speed above
4 mph (7 km/h).
Driving in special conditions
In certain driving conditions, such as, for
example:
driving close to a bend;
the vehicle ahead is leaving a
roundabout;
vehicles with small dimensions and/or
not aligned in the driving lane;
lane change by other vehicles;
vehicles travelling at right angles to
the vehicle.
system intervention might be
unexpected or delayed. The driver must
therefore be very careful, keeping
control of the vehicle to drive in complete
safety.
IMPORTANT In particularly complex
traffic conditions, the driver can
deactivate the system manually through
the Connect system.
Driving close to a bend
When entering or leaving a wide bend, the
system may detect a vehicle that is in
front of you, but that is not driving in the
same lane fig. 70. In cases such as these,
the system may intervene.
