ONBOARD DIAGNOSTIC
SYSTEM
Operation
The OBD (Onboard Diagnostic system)
carries out a continuous diagnosis of the
components of the vehicle related to
emissions.
It also alerts the driver of when these
components are no longer in peak
condition by switching on the
warning
light on the instrument panel (see
“Warning Lights And Messages”
paragraph in this chapter).
The aim of the OBD system (Onboard
Diagnostic) 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 your authorized dealer.
Note: After eliminating a fault, to check
the system completely, your 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 an
Onboard Diagnostic system (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 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 information.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal
requirement 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 notbe ready if
your vehicle was recently serviced,
recently had a dead 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
position, but do not crank or start the
engine.
Note: If you crank or start the engine,
you will have to start this test over.
101

2. As soon as you cycle the ignition
switch to the ON position, you will see the
“Malfunction 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 ten
seconds and then return to being fully
illuminated until you turn OFF the ignition
or start the engine. This means that your
vehicle's OBD II system is not readyand
you should notproceed 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 readyand 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.

GETTING TO KNOW YOUR INSTRUMENT PANEL

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 (P).
The detection area of the system covers
approximately a lane on both sides of the
vehicle which is around 9 feet (3 m).
This area begins from the door mirror and
extends for approximately 19 feet (6 m)
toward 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 an alert needs to be sent to the
driver. The system can detect the
presence of a vehicle in one of these
three areas.
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 activate 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.
Warning!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the
BSM system, always check your vehicle’s
mirrors, glance over your shoulder, and use
your turn signal before changing lanes.
Failure to do so can result in serious injury or
death.
Note:
For the system to operate properly,
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 you wish to install a rear tow eye
after purchasing the vehicle, you will
need to deactivate the system via the
Information and Entertainment System.
To access the function, select the
following items in sequence on the main
menu:
1. “Settings.”
2. “Safety.”
3. “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 31 mph
(50 km/h) in relation to your vehicle.0434132127USBSM Indicator Light

SAFETY

Overtaking Vehicles
If another vehicle is overtaken slowly,
with a difference in speed of less than
approximately 15 mph (25 km/h) and the
vehicle stays in the blind spot for
approximately 1.5 seconds, the warning
light on the door mirror of the
corresponding side illuminates.
If the difference in speed between the
two vehicles is greater than
approximately 15 mph (25 km/h), the
warning light does not illuminate.
Rear Cross Path Detection (RCP)
System
This system assists the driver during
reverse maneuvers in the case of reduced
visibility.
The RCP system monitors the rear
detection areas on both sides of the
vehicle to detect objects moving toward
the sides of the vehicle, with a minimum
speed between approximately 1 mph
(1 km/h) and 2 mph (3 km/h) and objects
moving at a maximum speed of 21 mph
(35 km/h), in areas such as parking lots.
The system activation is signaled to the
driver by an audible warning.
Note:If the sensors are covered by
objects or vehicles, the system may not
work as intended.
Warning!
Rear Cross Path Detection (RCP) is not a
back up aid system. It is intended to be used
to help a driver detect an oncoming vehicle in
a parking lot situation. Drivers must be
careful when backing up, even when using
RCP. Always check carefully behind your
vehicle, look behind you, and be sure to check
for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing
up. Failure to do so can result in serious
injury or death.
Operating Mode
The system may be activated/
deactivated via the Information and
Entertainment System. To access the
function, select the following items on
the main menu in sequence:
1. “Settings.”
2. “Safety.”
3. “Blind Spot Alert.”
"Blind Spot Alert", "Visual" Mode
When the system is enabled, the warning
light within the door mirror on the side of
the detected object illuminates.
The visual warning on the mirror will blink
if the driver activates the turn signals,
thus indicating the intention to change
lane. The warning light will be constant if the
driver stays in the same lane.
"Blind Spot Alert" Function
Deactivation
When the system is deactivated ("Blind
Spot Alert" mode off), the BSM or RCP
systems will not emit neither an acoustic
nor visual warning.
The BSM system will store the operating
mode that was active when the engine
was stopped. Each time the engine is
started, the operating mode last set will
be recalled and used.

Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC
position, the air bag system is not on and
the air bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag
system even if the battery loses power or
it becomes disconnected prior to
deployment.
The ORC turns on the Air Bag Warning
Light in the instrument panel for
approximately four to eight seconds for a
self-check when the ignition switch is
first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will
turn off. If the ORC detects a malfunction
in any part of the system, it turns on the
Air Bag Warning Light, either
momentarily or continuously. A single
chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that
will illuminate the instrument panel Air
Bag Warning Light if a malfunction is
detected that could affect the air bag
system. The diagnostics also record the
nature of the malfunction. While the air
bag system is designed to be
maintenance free, if any of the followingoccurs, have an authorized dealer service
the air bag system immediately.
The Air Bag Warning Light does not
come on during the four to eight seconds
when the ignition switch is first in the
ON/RUN position.
The Air Bag Warning Light remains on
after the four to eight-second interval.
The Air Bag Warning Light comes on
intermittently or remains on while
driving.
Note: If the speedometer, tachometer,
or any engine related gauges are not
working, the Occupant Restraint
Controller (ORC) may also be disabled. In
this condition the air bags may not be
ready to inflate for your protection. Have
an authorized dealer service the air bag
system immediately.
Warning!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if
it comes on as you drive, have an authorized
dealer service the air bag system
immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The
Redundant Air Bag Warning Light will
stay on until the fault is cleared. In
addition, a single chime will sound to alert
you that the Redundant Air Bag Warning
Light has come on and a fault has been
detected. If the Redundant Air Bag
Warning Light comes on intermittently or
remains on while driving have an
authorized dealer service the vehicle
immediately. For additional information
regarding the Redundant Air Bag Warning
Light refer to “Getting To Know Your
Instrument Panel” section of this manual.
Front Air Bags
This vehicle has front air bags and
lap/shoulder belts for both the driver and
front passenger. The front air bags are a
supplement to the seat belt restraint
systems. The driver front air bag is
mounted in the center of the steering
wheel. The passenger front air bag is
mounted in the instrument panel, above
the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on
the air bag covers.
123

Warning!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as
well.
Note:
Air bag covers may not be obvious in
the interior trim, but they will open
during air bag deployment.
After any collision, the vehicle should
be taken to an authorized dealer
immediately.
Enhanced Accident Response
System
In the event of an impact, if the
communication network remains intact,
and the power remains intact, depending
on the nature of the event, the ORC will
determine whether to have the Enhanced
Accident Response System perform the
following functions:
Cut off fuel to the engine (If Equipped)
Cut off battery power to the electric
motor (If Equipped)
Flash hazard lights as long as the
battery has power
Turn on the interior lights, which
remain on as long as the battery has
power or for 15 minutes from the
intervention of the Enhanced Accident
Response System.
Unlock the power door locks.
Your vehicle may also be designed to
perform any of these other functions in
response to the Enhanced Accident
Response System:
Turn off the Fuel Filter Heater, Turn off
the HVAC Blower Motor, Close the HVAC
Circulation Door
Cut off battery power to the:
– Engine
– Electric Motor (if equipped)

cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition switch to avoid draining
the battery. Carefully check the vehicle
for fuel leaks in the engine compartment
and on the ground near the engine
compartment and fuel tank before
resetting the system and starting the
engine. If there are no fuel leaks or
damage to the vehicle electrical devices
(e.g. headlights) after an accident, reset
the system by following the procedure
described below.
Enhanced Accident Response
System Reset Procedure
After the event occurs, when the system
is active, a message regarding fuel cutoff
is displayed. Turn the ignition switch from
ignition AVV/START or MAR/ACC/ON/
RUN to ignition STOP/OFF/LOCK.
Carefully check the vehicle for fuel leaks
in the engine compartment and on the
ground near the engine compartment and
fuel tank before resetting the system and
starting the engine.
Depending on the nature of the event the
left and right turn signal lights, located in
the instrument panel, may both be
blinking and will continue to blink. In order
to move your vehicle to the side of the
road, you must follow the system reset
procedure.
129

If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the climate
control BLOWER switch is set at high speed.
DO NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your heating
or cooling controls to force outside air into
the vehicle. Set the blower at high speed.
The best protection against carbon
monoxide entry into the vehicle body is a
properly maintained engine exhaust
system.
Whenever a change is noticed in the
sound of the exhaust system, when
exhaust fumes can be detected inside the
vehicle, or when the underside or rear of
the vehicle is damaged, have a competent
mechanic inspect the complete exhaust
system and adjacent body areas for
broken, damaged, deteriorated, or
mispositioned parts. Open seams or
loose connections could permit exhaust
fumes to seep into the passenger
compartment. In addition, inspect the
exhaust system each time the vehicle is
raised for lubrication or oil change.
Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced
immediately. Do not disassemble or
modify the system.
Front seat belt assemblies must be
replaced after a collision. Rear seat belt
assemblies must be replaced after a
collision if they have been damaged (i.e.,
bent retractor, torn webbing, etc.). If
there is any question regarding seat belt
or retractor condition, replace the seat
belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on
for four to eight seconds as a bulb check
when the ignition switch is first turned to
ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at
your authorized dealer as soon as
possible. After the bulb check, this light
will illuminate with a single chime when a
fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on
intermittently or remains on while
driving, have your authorized dealer
service the vehicle immediately. Refer to
“Occupant Restraint Systems” in “Safety”
for further information.

5. Start the compressor by placing the
power switch in the on position (I).
6. Inflate the tire to a pressure of at
least 32 psi (2.2 bar). Refer to “Tires” in
“Servicing And Maintenance” for more
information. In order to obtain a more
precise reading, check the pressure value
on pressure gauge with the compressor
off.
7. If the pressure is not at least 26 psi
(1.8 bar) after 15 minutes, disengage the
compressor from the valve and power
outlet. Then, move the vehicle forwards
approximately five tire turns in order to
distribute the sealing fluid inside the tire
evenly, and then repeat the inflation
operation.8. Drive the vehicle for about 5 miles
(8 km), stop, engage the electric park
brake, and recheck the tire pressure.
9. If the pressure is less than 19 psi
(1.3 bar),
DO NOTdrive the vehicle, and
see an authorized dealer.

to the padded area on the steering wheel.
Adhering the speed restriction sticker to the
padded area on the steering wheel is
dangerous because the air bag may not
operate (deploy) normally resulting in
serious injury. In addition, do not adhere the
sticker to areas where warning lights or the
speedometer cannot be viewed.
Note: Only use original sealant
cartridges, which can be purchased at an
authorized dealer.
Checking And Restoring Tire Pressure
The compressor can also be used to
check and, if necessary, restore the tire
pressure.
Proceed as follows:
1. Make sure that the power switch is in
the O (off) position.
2. Connect the hose directly to the valve
on the tire to be inflated.
3. Insert the plug into the socket in the
passenger compartment or in the cargo
