ENGINE IMMOBILIZER
Engine Immobilizer Operation
The Engine Immobilizer system prevents
unauthorized use of the vehicle by
disabling engine starting.
The system does not need to be enabled
or activated. Operation of the
immobilizer is automatic whether the
vehicle's doors are locked or unlocked.
When the ignition is set to ON, the Engine
Immobilizer system identifies the code
transmitted by the key. If the code is
recognized as valid, the Engine
Immobilizer system enables engine
starting.
When the ignition is brought back to
STOP, the Engine Immobilizer system
deactivates the engine control unit,
disabling engine starting.
For the correct engine starting
procedures, refer to “Starting The
Engine” in “Starting And Operating.”

GETTING TO KNOW YOUR VEHICLE

Irregular Operation
If the key code is not recognized during
starting, the Engine Immobilizer
Failure/Break-in Attempt
icon is
displayed on the instrument panel (refer
to "Warning Lights And Messages" in
"Getting To Know Your Instrument
Panel"). This condition leads to the engine
turning off after two seconds. In this
case, switch the ignition to STOP and
then to ON; if it is still blocked, try with
the other keys provided. If it is still not
possible to start the engine, contact an
authorized dealer.
If the Engine Immobilizer Failure/
Break-in Attempt
icon is displayed
while driving, this means that the system
is running a self-diagnosis (e.g. due to a
voltage drop). If the display persists,
contact an authorized dealer. Note:
Do not tamper with the Engine
Immobilizer system. Any modifications
or alterations could cause the protection
function to be deactivated.
The Engine Immobilizer system is not
compatible with certain aftermarket
remote starting systems. The use of
these devices could cause problems
when starting, as well as the
deactivation of the protection function.
All keys provided with the vehicle
have been programmed in accordance
with the electronics on the vehicle itself.
Each key has its own code which must
be stored by the system's control unit.
Contact an authorized dealer to have
new keys (up to eight) stored with a
code.
SECURITY ALARM SYSTEM —
IF EQUIPPED
Alarm Activation
The vehicle security alarm monitors the
vehicle doors and ignition for
unauthorized operation. When the vehicle
security alarm is activated, interior
switches for door locks are disabled. The
system provides both audible and visible
signals.
While armed, the alarm will sound in the
following scenarios:
Opening of doors/hood/liftgate
(perimeter protection)
Operation of ignition with a key which
is not validated
Cutting of the battery cables
Movement inside the passenger
compartment (volumetric protection — if
equipped)
Unexpected lifting/tilting of the
vehicle (anti-lift protection — if
equipped)
Activation of the alarm triggers the
acoustic warning and the turn signals.
Note: The alarm system is activated by
the Engine Immobilizer system, which is
automatically activated when you get out
of the vehicle with the key fob and lock
the doors.

GETTING TO KNOW YOUR INSTRUMENT PANEL

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.

Panic Brake Assist (PBA) System
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The system detects emergency braking
by monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the PBA system therefore
complements the ABS.
Maximum assistance from the PBA
system is obtained by pressing the brake
pedal very quickly. In addition, the brake
pedal should be pressed continuously
during braking, avoiding intermittent
presses, to get the most out of the
system. Do not reduce pressure on the
brake pedal until braking is no longer
necessary.
The PBA system is deactivated when the
brake pedal is released.Warning!
The Panic Brake Assist (PBA) cannot prevent
the natural laws of physics from acting on
the vehicle, nor can it increase the traction
afforded by prevailing road conditions. PBA
cannot prevent collisions, including those
resulting from excessive speed in turns,
driving on very slippery surfaces, or
hydroplaning. The capabilities of a
PBA-equipped vehicle must never be
exploited in a reckless or dangerous manner,
which could jeopardize the user's safety or
the safety of others.
Hill Start Assist (HSA) System
This is an integral part of the ESC system
that facilitates starting on slopes,
activating automatically in the following
cases:
Uphill: the vehicle is stationary on a
road with a gradient higher than 5%, the
engine is running, the brake is pressed,
and the transmission is in NEUTRAL (N)
or a gear other than REVERSE (R) is
engaged.
Downhill: the vehicle is stationary on a
road with a gradient higher than 5%, the
engine is running, the brake is pressed,
and the transmission is in REVERSE (R). When starting from a stop, the ESC
system control unit maintains the braking
pressure on the wheels until the engine
torque necessary for starting is reached,
or in any case for a maximum of two
seconds, allowing your right foot to be
moved easily from the brake pedal to the
accelerator.
The system will automatically deactivate
after two seconds without starting,
gradually releasing the braking pressure.
During this release stage, it is possible to
hear a typical mechanical brake release
noise, indicating the imminent movement
of the vehicle.
Warning!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight
rolling may occur, such as on minor hills or
with a loaded vehicle, or while pulling a
trailer. HSA is not a substitute for active
driving involvement. It is always the driver’s
responsibility to be attentive to distance to
other vehicles, people, and objects, and most
importantly brake operation to ensure safe
operation of the vehicle under all road
conditions. Your complete attention is
always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision or
serious personal injury.
106
SAFETY

The system has been designed for road
use only. If the vehicle is driven on a track,
the system must be deactivated to avoid
unnecessary warnings. Automatic
deactivation is signaled by the dedicated
warning light/symbol switching on in the
instrument panel (refer to the instructions in
the "Warning Lights And Messages On The
Instrument Panel" in "Getting To Know Your
Instrument Panel" for further information).
General Information
This vehicle has systems that operate on
radio frequency that comply with Part
15 of the Federal Communications
Commission (FCC) rules and with
Industry Canada Standards RSS-
GEN/210/220/310.
Operation is subject to the following two
conditions:
1. The device may not cause harmful
interference.
2. The device must accept any
interference received, including
interference that may cause undesired
operation of the device.
Changes or modifications to any of these
systems by other than an authorized
service facility could void authorization
to use this equipment.
Tire Pressure Monitoring System
(TPMS)
The vehicle is equipped with a Tire
Pressure Monitoring System (TPMS) that
sends the inflation pressure information
of each tire to the control unit, and will
signal the driver in the event of
insufficient tire pressure.
Tire pressure will vary with temperature
by approximately 1 psi (7 kPa) for every
12°F (6.5°C). This means that when the
outside temperature decreases, the tire
pressure will also decrease. Tire pressure
should always be set based on cold
inflation tire pressure. This is defined as
the tire pressure after the vehicle has not
been driven for at least three hours, or
driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire
sidewall. Refer to “Tires” in “Servicing
And Maintenance” for information on
how to properly inflate the vehicle’s tires.
The tire pressure will also increase as the
vehicle is driven. This is normal, and there
should be no adjustment for this
increased pressure.
The TPMS will signal the driver if
pressure falls below the warning limit for
any reason, including the effects of low
temperature and normal loss of pressure
from the tire.
The TPMS will stop indicating insufficient
tire pressure when pressure is equal to or
greater than the prescribed cold inflation level. Therefore, if insufficient tire
pressure is indicated by the (
) warning
light displaying in the instrument cluster,
increase the inflation pressure up to the
prescribed cold inflation value.
The system will automatically update,
and the “Tire Pressure Monitoring
Warning Light” will turn off once the
system receives the updated tire
pressures. The vehicle may need to be
driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS
to receive this information.
Operating Example
For example, your vehicle may have a
recommended cold (parked for more than
three hours) placard pressure of 33 psi
(227 kPa). If the ambient temperature is
68°F (20°C), and the measured tire
pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will
decrease the tire pressure to
approximately 24 psi (165 kPa). This tire
pressure is low enough to turn on the
“Tire Pressure Monitoring Warning Light.”
Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the “Tire Pressure
Monitoring Warning Light” will still be on.
In this situation, the “Tire Pressure
Monitoring Warning Light” will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard
pressure value.

SAFETY

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has
multistage driver and front passenger air
bags. This system provides output
appropriate to the severity and type of
collision as determined by the Occupant
Restraint Controller (ORC), which may
receive information from the front
impact sensors (if equipped) or other
system components.
The first stage inflator is triggered
immediately during an impact that
requires air bag deployment. A low
energy output is used in less severe
collisions. A higher energy output is used
for more severe collisions.
This vehicle may be equipped with a
driver and/or front passenger seat belt
buckle switch that detects whether the
driver or front passenger seat belt is
buckled. The seat belt buckle switch may
adjust the inflation rate of the Advanced
Front Air Bags.
This vehicle may be equipped with driver
and/or front passenger seat track
position sensors that may adjust the
inflation rate of the Advanced Front Air
Bags based upon seat position.
Warning!
No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air bag
to inflate.
Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags and
you could be injured because the air bags
may no longer be functional. The protective
covers for the air bag cushions are designed
to open only when the air bags are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, air bags
won’t deploy at all. Always wear your seat
belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide
additional protection by supplementing
the seat belts. Front air bags are not
expected to reduce the risk of injury in
rear, side, or rollover collisions. The front
air bags will not deploy in all frontal
collisions, including some that may
produce substantial vehicle damage —
for example, some pole collisions, truck
underrides, and angle offset collisions.
On the other hand, depending on the type and location of impact, front air bags may
deploy in crashes with little vehicle
front-end damage but that produce a
severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good
indicators of whether or not an air bag
should have deployed.
Seat belts are necessary for your
protection in all collisions, and also are
needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision
requiring the front air bags, it signals the
inflator units. A large quantity of
non-toxic gas is generated to inflate the
front air bags.
The steering wheel hub trim cover and
the upper passenger side of the
instrument panel separate and fold out of
the way as the air bags inflate to their full
size. The front air bags fully inflate in less
time than it takes to blink your eyes. The
front air bags then quickly deflate while
helping to restrain the driver and front
passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect
the knees of the driver and front
passenger, and position the front
occupants for improved interaction with
the front air bags.

The automatic activation of PARK (P)
when the engine is stopped can also be
deactivated on the Information and
Entertainment system by selecting the
following functions on the main menu:
"Settings", "Driver Assistance" and
"Automatic Parking Brake".
Important Notes
Failure to comply with what is reported
below may damage the transmission:
Shift into PARK (P) mode only with the
vehicle at a standstill.
Select REVERSE (R) mode, or pass
from REVERSE to another mode only
with the vehicle at a standstill and engine
idling.
Do not change between PARK (P),
REVERSE (R), NEUTRAL (N) or DRIVE (D)
modes with engine running at a speed
above idling.
Before activating any transmission
operating mode, fully depress the brake
pedal.
Note: The unexpected movement of the
vehicle can injure the occupants or
people nearby. Do not leave the vehicle
with engine running: before getting out of
the passenger compartment always
engage the electric park brake, select the
PARK (P) mode, stop the engine.
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.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always apply the park brake, shift
the transmission into PARK, and turn the
ignition STOP/OFF. When the ignition is in
the STOP/OFF mode, the transmission is
locked in PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always make
sure the ignition is in the STOP/OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allowing
children to be in a vehicle unattended 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
children), and do not leave the ignition in the
AVV or ON mode. A child could operate
power windows, other controls, or move the
vehicle.
Caution!
Only engage the gear with engine at idling
while fully depressing the brake pedal. If the
transmission temperature exceeds the
normal operating limits, the transmission
control unit may change the gear
engagement order and reduce the drive
torque. If the transmission overheats, it
could operate incorrectly until it cools down.
When using the vehicle with extremely
low external temperatures, the
transmission operation may change
depending on the engine and transmission
temperature, as well as vehicle speed.
Activation of the torque converter clutch
and of the eighth gear is inhibited until the
transmission oil is correctly warmed up.
Complete operation of the transmission will
be enabled as soon as the fluid temperature
reaches the predefined value.
