ONBOARD DIAGNOSTIC
SYSTEM
Operation
The Onboard Diagnostic system (OBD) carries
out a continuous diagnosis of the components
of the vehicle related to emissions.
It also alerts the driver of when these compo-
nents are no longer in peak condition by
switching on the warning light on the instru -
ment panel
Ú
page 73.
The aim of the OBD system (Onboard Diag -
nostic) is to:
Monitor the efficiency of the system
Indicate an increase in emissions
Indicate the need to replace damaged
components The vehicle also has a connector, which can
interface with appropriate tools, that 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 be carried out
by an authorized dealer.

NOTE:

After eliminating a fault, to check the system
completely, an authorized dealer is obliged to
run tests and, if necessary certain road tests.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may
need to access this information to assist with
the diagnosis and service of your vehicle and
emissions system.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
• Be possible that vehicle systems,
including safety related systems,
could be impaired or a loss of vehicle
control could occur that may result in an accident involving serious injury or
death.
• Access, or allow others to access,
information stored in your vehicle
systems, including personal informa-
tion.

EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal require-
ment to pass an inspection of your vehicle's
emissions control system. Failure to pass
could prevent vehicle registration.
For states that require an Inspection
and Maintenance (I/M), this check
verifies the Malfunction Indicator
Light (MIL) is functioning and is not
on when the engine is running, and that the
OBD II system is ready for testing.
Normally, the OBD II system will be ready. The
OBD II system may not be ready if your vehicle
was recently serviced, recently had a depleted
battery or a battery replacement. If the OBD II
system should be determined not ready for the
I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated
test, which you can use prior to going to the
test station. To check if your vehicle's OBD II
system is ready, you must do the following:
1. Cycle the ignition switch to the ON posi -
tion, but do not crank or start the engine.

NOTE:

If you crank or start the engine, you will have to
start this test over. 2. As soon as you cycle the ignition switch to
the ON position, you will see the Malfunc -
tion Indicator Light (MIL) symbol come on
as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds
and then return to being fully illumi-
nated until you turn OFF the ignition or
start the engine. This means that your
vehicle's OBD II system is not ready and
you should not proceed to the I/M
station.
• The MIL will not flash at all and will
remain fully illuminated until you place the ignition in the off position or start
the engine. This means that your
vehicle's OBD II system is ready and you
can proceed to the I/M station. If your

OBD II system is
not ready, you should
see an authorized dealer or repair facility. If
your vehicle was recently serviced or had a
battery failure or replacement, you may need
to do nothing more than drive your vehicle as
you normally would in order for your OBD II
system to update. A recheck with the above
test routine may then indicate that the system
is now ready .
Regardless of whether your vehicle's OBD II
system is ready or not, if the MIL is illuminated
during normal vehicle operation you should
have your vehicle serviced before going to the
I/M station. The I/M station can fail your
vehicle because the MIL is on with the engine
running.

TRAILER TOWING
Trailer towing is not recommended for this
vehicle.
SUGGESTIONS FOR DRIVING
Saving Fuel
Below are some suggestions which may help
you save fuel and lower the amount of harmful
emissions released into the atmosphere.
Vehicle Maintenance
Checks and operations should be carried out
in accordance with the Maintenance Plan

Ú
page 204.
Tires
Check the tire pressures at least once every
four weeks: if the pressure is too low,
consumption levels increase as resistance to
rolling is higher.
Unnecessary Loads
Do not travel with an overloaded trunk. The
weight of the vehicle and its arrangement
greatly affect fuel consumption and stability.
Electric Devices
Use electrical systems only for the amount of
time needed. The rear window defroster, addi -
tional headlights, windshield wipers and
heater blower fan require a considerable
amount of energy; increasing the current
uptake increases fuel consumption (by up to
+25% when city driving). Climate Control System
Using the climate control system will increase
consumption: use standard ventilation when
the temperature outside permits.
Devices for Aerodynamic Control
The use of non-certified devices for aerody
-
namic control may adversely affect air drag
and consumption levels.
Driving Style
Starting
Do not warm up the engine at low or high revs
when the vehicle is stationary; this causes the
engine to warm up more slowly, thereby
increasing fuel consumption and emissions. It
is therefore advisable to drive off immediately,
slowly, avoiding high speeds: by doing this the
engine will warm up more quickly.
Unnecessary Actions
Avoid revving up when starting at traffic lights
or before stopping the engine. This action is
unnecessary and causes increased fuel
consumption and pollution.
Gear Selection
Use a high gear when traffic and road condi -
tions allow it. Using a low gear for faster accel -
eration will increase fuel consumption.
Improper use of a high gear increases
consumption, emissions and engine wear. Max. Speed
Fuel consumption considerably increases as
speed increases. Maintain a constant speed,
avoiding unnecessary braking and accelera
-
tion, which cost in terms of both fuel consump -
tion and emissions.
Acceleration

Accelerating violently severely affects consump -
tion and emissions: acceleration should be
gradual and should not exceed the maximum
torque.

Conditions Of Use
Cold Starting
Short trips and frequent cold starts will not
allow the engine to reach optimum operating
temperature. This results in a significant
increase in consumption levels (from +15 to
+30% in city driving) and emissions.
Traffic And Road Conditions
High fuel consumption is caused by heavy
traffic, for instance when traveling in traffic
with frequent use of low gears or in cities with
many traffic lights. Winding mountain roads
and rough road surfaces also adversely affect
consumption.
Stops In Traffic
During prolonged stops (e.g. railway cross -
ings), turn off the engine.

Blind Spot Monitoring (BSM) System — If
Equipped
The BSM system uses two radar sensors,
located in the rear fascia/bumper (one on
each side), to detect the presence of other
vehicles in the rear side blind spots of your
vehicle.Rear Sensor Location
The system warns the driver about the pres -
ence of other vehicles in the detection area by
illuminating the BSM Warning Light located
within the door mirror on the side in which the
other vehicle was detected. If equipped, an
audible chime will also be heard to alert the
driver (if option is selected within the radio
system). BSM Indicator Light
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active.
Sensors
The sensors are activated when any forward
gear is engaged at a speed higher than
approximately 6 mph (10 km/h) or when
REVERSE is engaged.
The sensors are temporarily deactivated when
the vehicle is stationary or the vehicle is in
PARK.
The detection area of the system covers
approximately one lane on both sides of the
vehicle.
This area begins from the door mirror and
extends for approximately 19 ft (6 m) towards
the rear part of the vehicle. When the sensors are active, the system moni
-
tors 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 detec -
tion zone to check whether it is necessary to
send a signal to the driver on both sides. The
system monitors this detection zone in three
different situations:
When you are being overtaken by a vehicle.
When you are overtaking a vehicle.
When a vehicle approaches from the side.

NOTE:

The system does not alert the driver of the
presence of fixed objects (e.g. safety
barriers, poles, walls, etc.). However, in
some circumstances, the system may acti -
vate in the presence of these objects. This is
normal and does not indicate a system
malfunction.
The system does not alert the driver about
the presence of vehicles coming from the
opposite direction, in the adjacent lanes.
If a trailer is hitched to the car, the system
automatically deactivates.

NOTE:

If the safety belts of the front seats are not
correctly fastened, the system will not inter-
vene on the braking system (only audible and
visual signals will be provided).
Changing The System Sensitivity
The sensitivity of the system can be changed
through the radio system menu, choosing from
one of the following three options: "Near",
"Medium" or "Far". Refer to the description in
the Information and Entertainment System
Owner’s Manual Supplement for how to
change the settings.
The default setting is "Medium". With this
setting, the system warns the driver of a
possible collision with the vehicle in front
when that vehicle is at a standard distance,
between that of the other two settings.
With the system sensitivity set to "Far", the
system will warn the driver of a possible colli -
sion with the vehicle in front 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 driver
with the maximum possible reaction time to
prevent a potential collision.
With the option set to "Near", the system will
alert the driver of a possible collision with the
vehicle in front when that vehicle is close. This
setting offers the driver a lower reaction time
compared to the "Medium" and "Far" settings,
in the event of a potential collision, but
permits more dynamic driving of the vehicle. The system sensitivity setting is kept in the
memory when the engine is turned off.
System Limited Operation Warning
If a dedicated message is displayed, a condi
-
tion limiting the system operation may have
occurred. The possible reasons of this limita -
tion are if something is blocking the camera
view, or a fault is present.
If an obstruction is signaled, clean the area of
the windshield.
Although the vehicle can still be driven in
normal conditions, the system may be not
completely available.
When the conditions limiting the system func -
tions end, this will go back to normal and
complete operation. Should the fault persist,
contact an authorized dealer.
System Failure Signaling
If the system turns off and a dedicated
message is shown on the display, it means
that there is a fault with the system.
In this case, it is still possible to drive the
vehicle, but you are advised to contact an
authorized dealer as soon as possible.
Radar Indication Not Available
If conditions are such that the radar cannot
detect obstacles correctly, the system is deac -
tivated 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 function of this system can also be tempo
-
rarily reduced due to obstructions such as
mud, dirt or ice on the fascia/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 condi -
tions of high reflectivity (e.g. tunnels with
reflective tiles or ice or snow). When the condi -
tions limiting the system functions end, it will
go back to normal and complete operation.
In certain 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 reason
behind this message, check if the sensor is
dirty. It could be necessary to clean or remove
any obstructions in the area.

If the message appears frequently, even in the
absence of atmospheric conditions such as
snow, rain, mud or other obstructions, contact an
authorized dealer for a sensor alignment check.

In the absence of visible obstructions, manu -
ally removing the decorative cover trim and
cleaning the radar surface could be required.
Have this operation performed at an autho -
rized dealer.

NOTE:

It is recommended that you do not install
devices, accessories, or aerodynamic attach -
ments in front of the sensor or darken it in any
way, as this can compromise the correct func -
tioning of the system.
