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.

2. Fully press the brake pedal without touching the accelerator.
3. Briefly push the ignition button.
4. If the engine doesn't start within a few seconds, you need to repeat the proce -
dure.
If the problem persists, contact an authorized
dealer.
Remote Starting System
This system uses the key fob to start the
engine conveniently from outside the vehicle
while still maintaining security. The system
has a range of at least 300 feet (91 meters).
The remote starting system also activates the
climate control, the heated seats (if
equipped), and the heated steering wheel (if
equipped), depending on temperatures
outside and inside of the vehicle.

NOTE:

Obstructions between the vehicle and key fob
may reduce this range.
WARNING!
When leaving the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.

Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be warned
not to touch the parking brake, brake pedal
or the transmission gear selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil -
dren. A child could operate power windows,
other controls, or move the vehicle.

Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in
an attempt to start the vehicle. This could
result in flash fire causing serious
personal injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine
has started, ignite and damage the
converter and vehicle.

If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle

Ú
page 199. This type of
start can be dangerous if done improperly.

tion of remote start also until the ignition is
placed in the ON/RUN mode. Remote Start Windshield Wiper De–Icer Acti
-
vation — If Equipped
When remote start is active and the outside
ambient temperature is less than 39°F (4°C),
the Windshield Wiper De-Icer will be enabled.
Exiting remote start will resume previous oper -
ation, except if the Windshield Wiper De-Icer is
active.
The Windshield Wiper De-Icer timer and oper -
ation will continue.
Cold Weather Operation
To prevent possible engine damage while
starting at low temperatures, this vehicle will
inhibit engine cranking when the ambient
temperature is less than –22°F (–30°C) and
the oil temperature sensor reading indicates
an engine block heater has not been used. An
externally-powered electric engine block
heater is available as optional equipment or
from an authorized dealer.
The message “plug in engine heater” will be
displayed in the instrument cluster when the
ambient temperature is below 5°F (–15°C) at
the time the engine is shut off as a reminder to
avoid possible crank delays at the next cold
start.
Extended Park Starting
If the vehicle has not been started or driven for
at least 30 days, it is advisable to follow the
indications below.
To start the engine, proceed as follows:
1. Briefly push the ignition button
2. If the engine does not start, wait five seconds and let the starter cool down and
then repeat the starting procedure
3. If the engine does not start after eight attempts, let the starter cool down for at
least 10 seconds, and then repeat the
starting procedure
If the problem persists, contact an authorized
dealer.

NOTE:

After prolonged vehicle inactivity, very difficult
starting, that can be noticed through rapid
fatigue of the starter, might also be due to a
discharged battery. In this case you may jump
start the vehicle
Ú
page 199.
CAUTION!
Use of the recommended oil and adhering
to the prescribed oil change intervals is
important to prevent engine damage and
ensure satisfactory starting in cold

If Engine Fails To Start
Starting the Engine with Key Fob Battery Run
Down or Drained
If the ignition does not respond when the
button is pushed, the key fob battery might be
run down or drained. Therefore, the system
does not detect the presence of the key fob in
the vehicle, and will display a dedicated
message.
For more information on starting with a
discharged key fob battery
Ú
page 19.
After Starting — Warming Up The Engine
Proceed as follows:

Travel slowly, letting the engine run at a
reduced RPM, without accelerating suddenly.

It is recommended to wait until the digital
engine coolant temperature indicator starts
to rise for maximum performance.
Stopping The Engine
To stop the engine, proceed as follows:
1. Park the vehicle in a position that is not
dangerous for oncoming traffic.
2. Engage the PARK (P) mode.
3. With engine idling, push the ENGINE START/STOP button on the steering wheel
to STOP the engine.

NOTE:

Do not leave the ignition in ACC mode when
the engine is off.
To shut off the engine with vehicle speed
greater than 5 mph (8 km/h), you must push
and hold the ignition or push the ENGINE
START/STOP button three times consecutively within a few seconds. The engine will shut
down, and the ignition will be placed in the
ACC mode
With the keyless ignition system, it is possible
to leave the vehicle taking the key fob with you
without the engine switching off. The vehicle
will inform the absence of the key on board,
only if the doors are closed.
Stopping the engine (cycling from the ACC to
the OFF position), the accessories are still
powered for about three minutes, or until a
door is opened.
When the ignition is in the OFF mode, the
window switches remain active for three
minutes. Opening a front door will cancel this
function.
After severe driving, idle the engine to allow
the temperature inside the engine compart
-
ment to cool before shutting off the engine.
Turbocharger Cool Down
It is recommended before switching the
vehicle off, to keep the engine idling for a few
minutes so that the turbocharger can be suit -
ably lubricated. This procedure is particularly
recommended after severe driving.

After a full load operation, keep the engine idling
for three to five minutes before switching it off.

This time allows the lubricating oil and the
engine coolant to eliminate the excessive heat
from combustion chamber, bearings, inner
components and turbocharger.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in
an attempt to start the vehicle. This could
result in flash fire causing serious
personal injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine
has started, ignite and damage the
converter and vehicle.

If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle

Ú
page 199. This type of
start can be dangerous if done improperly.

CAUTION!

To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds before
trying again.

installed option. If your vehicle is not
equipped, heater cords are available from
an authorized dealer.

The engine block heater will require 110 Volts
AC and 6.5 Amps to activate the heater
element.

The engine block heater must be plugged in
at least one hour to have a warming effect
on the engine and at least four hours to
have a warming effect when ambient
temperatures are below -20°F (-29°C).
ENGINE BREAK-IN
RECOMMENDATIONS
Engine Break-In
For both engines, use the following engine
break-in recommendations:

NOTE:

A new engine may consume some oil during its
first few thousand miles (kilometers) of opera
-
tion. This should be considered a normal part
of the break-in period and not interpreted as
an indication of a problem. Please monitor
your oil level during the break-in period and
add oil as required.
It is recommended for the operator to observe
the following driving behaviors during the new
vehicle break-in period:
0 to 100 miles (0 to 160 km):
Do not allow the engine to operate at idle for
an extended period of time.

Press the accelerator pedal slowly and not
more than halfway to avoid rapid acceleration.

Avoid aggressive braking.

Drive with the engine speed less than
3,500 RPM.

Maintain vehicle speed below 55 mph
(88 km/h) and observe local speed limits.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

100 to 300 miles (160 to 483 km):
Press the accelerator pedal slowly and not
more than halfway to avoid rapid accelera-
tion in lower gears (FIRST to THIRD gears).
Avoid aggressive braking.

Drive with the engine speed less than
5,000 RPM.

Maintain vehicle speed below 70 mph
(112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
Exercise the full engine RPM range, shifting
manually (paddles or gear shift) at higher
RPM when possible.
Do not perform sustained operation with
the accelerator pedal at wide open throttle.
Maintain vehicle speed below 85 mph
(136 km/h) and observe local speed limits.
For the first 1,500 miles (2,414 km):
Do not participate in track events, sport
driving schools, or similar activities during
the first 1,500 miles (2,414 km).

NOTE:

Monitor engine oil with every refueling and add
if necessary. Oil and fuel consumption may be
higher through the first oil change interval.
ELECTRIC PARK BRAKE (EPB)
The EPB features a switch located on the
center console, a caliper with motor for each
rear wheel, and an electronic control module.
Electric Park Brake Switch
The EPB can be engaged in two ways:
Manually, by pulling the switch on the
center console.
Automatically, in “Safe Hold” or “Auto Park
Brake” conditions.

NOTE:

Normally, the EPB is engaged automatically
when the engine is stopped. This function can
be deactivated/activated on the Information
and Entertainment system by selecting the
following items in sequence on the main
menu: “Settings”, “Driver Assistance” and
“Automatic Parking Brake”. In addition to engaging the EPB, along with
steering and positioning chocks in front of the
wheels (when on a steep slope), you must
always place the vehicle in the PARK (P) mode
before leaving.

Should the vehicle battery be faulty, the battery
must be replaced in order to unlock the EPB.

Engaging The EPB Manually
Briefly pull the switch located on the center
console to manually engage the EPB when the
vehicle is stationary.
Noise may be heard from the rear of the
vehicle when engaging the EPB.
A slight movement of the brake pedal may be
detected when engaging the EPB with the
brake pedal pressed.
With the EPB engaged, the BRAKE warning
light on the instrument panel and the switch
will illuminate. CAUTION!
With the EPB failure warning light on, some
functions of the EPB are deactivated. In this
case the driver is responsible for brake
activation and vehicle parking in complete
safety conditions.

(Continued)
Electric Park Brake (EPB) Operating Modes
The EPB may operate as follows:
“Dynamic Operating Mode”: this mode is
activated by pulling the switch repeatedly
while driving.
“Static Engagement and Release Mode”:
with the vehicle stationary, the EPB can be
activated by pulling the switch on the center
console once. Push the switch and the
brake pedal at the same time to disengage
the brake.
“Drive Away Release”: the EPB will automat-
ically disengage with the driver side seat
belt fastened and the detection of an action
performed by the driver to move the vehicle
(forward gear or reverse gear). This feature
can be turned on or off in the Information
and Entertainment System.

NOTE:

If the car is equipped with carbon-ceramic
brake discs, it is necessary to fasten the seat
belts or turn off the EPB before starting to
avoid damages to the ceramic brake discs.
“Safe Hold”: if the vehicle speed is lower
than 1.9 mph (3 km/h), the gear selector is
not in PARK (P) position and the driver's
intention of leaving the vehicle is detected,
the EPB will automatically engage to hold
the vehicle in safety conditions.
“Auto Park Brake”: if the vehicle speed is
below 1.9 mph (3 km/h), the EPB will auto -
matically engage when the gear selector is
in PARK (P) position. The light on the switch
located on the center console switches on
together with the BRAKE warning light on
the instrument panel when the parking
brake is engaged and applied to the wheels.
Each automatic parking brake engagement
can be canceled by pressing the switch on
the center console and at the same time
moving the gear selector for the transmis -
sion to position PARK (P).
Safe Hold
Safe Hold is a safety function that automati -
cally engages the Electric Park Brake in the
event of a dangerous condition for the vehicle.
The Electric Park Brake engages automatically
to prevent vehicle movement if:
The vehicle speed is below 2 mph (3 km/h).
A transmission operating mode different
from PARK (P) is activated.
The driver's seat belt is not fastened.
The driver side door is open.
No attempts to apply pressure on the brake
pedal have been detected.
The vehicle is parked on roads with a slope
of more than 4%. The “Safe Hold” function can be temporarily
disabled by pushing the switch located on the
center console and the brake pedal at the
same time, with the vehicle stationary and the
driver side door open.
Once disabled, the function will activate again
when the vehicle speed reaches 12 mph
(20 km/h) or the ignition is cycled to OFF and
then to ACC.
AUTOMATIC TRANSMISSION
The vehicle is equipped with an electronically
controlled 8-speed automatic transmission
where gear shifting automatically takes place,
depending on the vehicle usage instanta
-
neous parameters (vehicle speed, grade, and
accelerator pedal position).
Manual gear shifting can still occur thanks to
the “sequential mode” position for the gear
selector.
WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
