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.
125

SABICs may help reduce the risk of head
and other injuries to front and rear seat
outboard occupants in certain side
impacts, in addition to the injury
reduction potential provided by the seat
belts and body structure.
The SABIC deploys downward, covering
the side windows. An inflating SABIC
pushes the outside edge of the headliner
out of the way and covers the window.
The SABICs inflate with enough force to
injure occupants if they are not belted
and seated properly, or if items are
positioned in the area where the SABICs
inflate. Children are at an even greater
risk of injury from a deploying air bag.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle
occupants through side windows in
certain side impact events.
Warning!
Do not mount equipment, or stack
luggage or other cargo up high enough to
block the deployment of the SABICs. The
trim covering above the side windows where
the SABIC and its deployment path are
located should remain free from any
obstructions.
In order for the SABICs to work as
intended, do not install any accessory items
in your vehicle which could alter the roof. Do
not add an aftermarket sunroof to your
vehicle. Do not add roof racks that require
permanent attachments (bolts or screws) for installation on the vehicle roof. Do not
drill into the roof of the vehicle for any
reason.
Side Impacts
The Side Air Bags are designed to
activate in certain side impacts. The
Occupant Restraint Controller (ORC)
determines whether the deployment of
the Side Air Bags in a particular impact
event is appropriate, based on the
severity and type of collision. The side
impact sensors aid the ORC in
determining the appropriate response to
impact events. The system is calibrated
to deploy the Side Air Bags on the impact
side of the vehicle during impacts that
require Side Air Bag occupant protection.
In side impacts, the Side Air Bags deploy
independently; a left side impact deploys
the left Side Air Bags only and a
right-side impact deploys the right Side
Air Bags only. Vehicle damage by itself is
not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all
side collisions, including some collisions
at certain angles, or some side collisions
that do not impact the area of the
passenger compartment. The Side Air
Bags may deploy during angled or offset
frontal collisions where the front air bags
deploy.
Side Air Bags are a supplement to the
seat belt restraint system. Side Air Bags
deploy in less time than it takes to blink
your eyes.
Warning!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even if
they are in an infant or child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your
protection in all collisions. They also help
keep you in position, away from an inflating
Side Air Bag. To get the best protection
from the Side Air Bags, occupants must
wear their seat belts properly and sit
upright with their backs against the seats.
Children must be properly restrained in a
child restraint or booster seat that is
appropriate for the size of the child.
Warning!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit upright
in the center of the seat.
Being too close to the Side Air Bags
during deployment could cause you to be
severely injured or killed.
127

Relying on the Side Air Bags alone could
lead to more severe injuries in a collision.
The Side Air Bags work with your seat belt
to restrain you properly. In some collisions,
Side Air Bags won’t deploy at all. Always
wear your seat belt even though you have
Side Air Bags.
Note: Air bag covers may not be obvious
in the interior trim, but they will open
during air bag deployment.
Rollover Events
Side Air Bags are designed to activate in
certain rollover events. The ORC
determines whether the deployment of
the Side Air Bags in a particular rollover
event is appropriate, based on the
severity and type of collision. Vehicle
damage by itself is not a good indicator
of whether or not Side Air Bags should
have deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing
system determines if a rollover event
may be in progress and whether
deployment is appropriate. In the event
the vehicle experiences a rollover or near
rollover event, and deployment of the
Side Air Bags is appropriate, the rollover
sensing system will also deploy the seat
belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle
occupants through side windows in
certain rollover or side impact events.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
Note: Front and/or side air bags will not
deploy in all collisions. This does not
mean something is wrong with the air bag
system. If you do have a collision which deploys
the air bags, any or all of the following
may occur:
The air bag material may sometimes
cause abrasions and/or skin reddening to
the occupants as the air bags deploy and
unfold. The abrasions are similar to
friction rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with
chemicals. They are not permanent and
normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see
your doctor immediately.
As the air bags deflate, you may see
some smoke-like particles. The particles
are a normal by-product of the process
that generates the non-toxic gas used for
air bag inflation. These airborne particles
may irritate the skin, eyes, nose, or
throat. If you have skin or eye irritation,
rinse the area with cool water. For nose
or throat irritation, move to fresh air. If
the irritation continues, see your doctor.
If these particles settle on your clothing,
follow the garment manufacturer’s
instructions for cleaning.
Do not drive your vehicle after the air
bags have deployed. If you are involved in
another collision, the air bags will not be
in place to protect you.

Remote Start Comfort Systems — If
Equipped
When Remote Start is activated, the
heated steering wheel and driver heated
seat features will automatically turn on in
cold weather.
These features will stay on through the
duration of remote start until the ignition
is cycled to the ON/RUN mode.
Remote Start Windshield Wiper De–Icer
Activation — 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 operation, except if the
Windshield Wiper De-Icer is active.
The Windshield Wiper De-Icer timer and
operation 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
your 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.
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
conditions.
Extended Park Starting
If the vehicle has not been started or
driven for at least 90 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 your
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 partially flat
battery. In this case, refer to "Jump
Starting" in "In Case Of Emergency".
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.
In this case, follow the instructions
outlined in "Starting With A Discharged
Key Fob Battery" in the "Getting To Know
Your Vehicle" chapter, and start the
engine normally.
147

System Activation
The activation of the system is indicated
by the
symbol lighting up on the
display. In this condition, the light on the
button is off.
System Deactivation
A message will appear on the display
when the system is deactivated. In this
condition, the light on the button is on.
Note: Each time the engine is started,
the system is activated regardless of
where was when it was previously
switched off.
Possible Reasons The Engine Does Not
Autostop
For higher comfort and increased safety,
and to reduce emissions, there are
certain conditions where the engine will
not autostop despite the system being
active, such as:
Engine still cold.
Especially cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
Reverse gear engaged (e.g. for parking
maneuvers).
With the automatic climate control
active, an adequate cabin heating or
cooling comfort has not been reached or
with MAX-DEF function active.
During the first period of use, to
initialize the system.
Steering angle beyond threshold.
Engine Restarting Conditions
Due to comfort, emission control, and
safety reasons, the engine can restart
automatically without any action by the
driver, under special conditions, such as:
Battery not sufficiently charged.
Reduced braking system vacuum (e.g.
if the brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on
roads with a grade).
Engine stopping by the Stop/Start
system for more than approx. three
minutes.
With the automatic climate control
active, an adjustment in cabin heating or
cooling is made or with MAX-DEF
function active.
Safety Functions
When the engine is stopped through the
Stop/Start system, if the driver releases
their seat belt, opens the driver's or
passenger's door, or opens the hood from
inside the vehicle, the engine can be
restarted only by using the ignition.
This condition is indicated to the driver
both through a buzzer and a message on
the instrument cluster display.
Energy Saving Function
If the driver does not carry out any action
for more than three minutes after the
automatic engine restart, the Start/Stop
system will switch off the engine in order
to prevent fuel consumption.
In this situation, the engine can only be
restarted using the ignition device.
Note: It is possible to keep the engine
running by deactivating the system.
Irregular Operation
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, refer to "Warning
Lights and Messages" paragraph in
"Getting To Know Your Instrument Panel".
Vehicle Inactivity
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of the
battery power supply.
Proceed as follows:
Remove connector from socket to
disconnect sensor (battery status
monitoring) installed on the negative pole
of the battery. This sensor should never
be disconnected from the pole except if
the battery is replaced.
162
STARTING AND OPERATING

Note:After setting the ignition to STOP
and having closed the driver side door,
wait at least one minute before
disconnecting the electrical supply from
the battery. When reconnecting the
electrical supply to the battery, make
sure that the ignition is in the STOP mode
and the driver side door is closed.
SPEED LIMITER
Description
This feature allows the speed of the
vehicle to be limited to speeds, which can
be set by the driver.
The maximum speed can be set with the
vehicle stationary or in motion. The
minimum speed that can be set is 18 mph
(30mk/h).
When this feature is active, the vehicle
speed depends on the pressing of the
accelerator pedal until the programmed
speed limit is reached (see "Speed Limit
Programming" paragraph).
Activation
The feature can be activated/
deactivated through the Information and
Entertainment System.
Activating The Device
To access this feature on the main menu,
select the following items in sequence:
"Settings", "Safety", “Speed Limiter” and
“ON”.
The activation of this feature is signaled
by the displaying of the green symbol
along with the last speed set. The Speed
Limiter feature can remain active
concurrently with the Speed Control
system. If a speed limit below the one
indicated in the Speed Control is
selected, the Speed Control speed will be
lowered to that of the Speed Limiter. This
function remains available in RACE mode.
Speed Limit Programming
The speed limit can be programmed
through the Information and
Entertainment System.
To access the function on the main menu,
select the following items in sequence:
"Settings", "Safety" and "Speed Limiter
Set Speed".
By turning the Rotary Pad, the speed
increases by 5 mph (5 km/h), from a
minimum of 18 mph (30 km/h) to a
maximum of 112 mph (180 km/h).
Exceeding The Programmed Speed
By fully pressing the accelerator pedal,
the programmed speed can be exceeded
even with the device active (e.g. in the
event of overtaking).
The device is disabled until the speed
drops below the set limit, after which it
reactivates automatically.

you should accelerate until you are close
to that speed. Then, push and release the
RES button.
To Deactivate
Lightly pressing the brake pedal
deactivates the speed control without
deleting the set speed.
The speed control may also be
deactivated by applying the electric park
brake or when the braking system is
operated (e.g. operation of the ESC
system).
The set speed is deleted in the following
cases:
Pushing the on/off button twice
The ignition is cycled to the STOP
position
There is a malfunction with the Speed
Control.
ADAPTIVE CRUISE CONTROL
(ACC) — IF EQUIPPED
System Description
Adaptive Cruise Control (ACC) is a driver
assist system that combines the speed
control functions with maintaining the
distance from the vehicle ahead.
The system allows to set and hold the
vehicle at the desired speed without
needing to press the accelerator. It also
allows to set and hold a distance from the
vehicle ahead (these settings are set by
the driver).
The Adaptive Cruise Control (ACC)
system uses a radar sensor located
behind the front bumper and a camera
located in the center/upper part of the
windshield, to detect the presence of a
vehicle close ahead. This system enhances driving comfort
while on the highway or out of town with
light traffic.
If the sensor does not detect a vehicle
ahead, the system will maintain a fixed
set speed.
If the sensor detects a vehicle ahead, the
system automatically intervenes by
braking (or accelerating) slightly in order
keep the set distance while not
exceeding the original set speed, seeking
to adapt to the speed of the vehicle
ahead.
Note:
Adaptive Cruise Control
performance is not guaranteed under the
following circumstances, and it is

STARTING AND OPERATING

Setting a speed activates the system.
The display shows the icon in green with
the set speed.
Note:The system cannot be enabled
when RACE mode is active.
Warning!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it
to go faster than you want. You could lose
control and have a collision. Always leave
the system off when you are not using it.
Pausing / Deactivating
With the system enabled (speed not set),
push the
(on/off) button to disable.
With the system active (speed set), push
the
(on/off) button to pause. The
display will show the icon in white with
the speed in brackets. To then deactivate
the system, push the
(on/off) button
again.
Setting The Desired Speed
The speed can be set from a minimum of
20 mph (30 km/h) to a maximum of
110 mph (180 km/h).
When the vehicle reaches the desired
speed, push the SET switch upward or
downward and release it to activate the
system. When the accelerator is released,
the vehicle will maintain the set speed
automatically. While the accelerator pedal is pressed,
the system will not be able to control the
distance between the vehicle and the one
ahead. In this case, the speed will be
determined only by the position of the
accelerator pedal.
The system will return to normal
operation as soon as the accelerator
pedal is released.
The system
cannotbe set:
When pressing the brake pedal.
When the brakes are overheated.
When the electric park brake has been
operated.
When either PARK (P), REVERSE (R) or
NEUTRAL (N) is engaged.
When the engine rpm is above a
maximum threshold.
When the vehicle speed is not within
the operational speed range.
When the ESC (or ABS or other
stability control systems) are operating
or have just operated.
When the ESC system is off.
When the Forward Collision Warning
system (if equipped) is braking
automatically.
In the event of system failure.
When the engine is OFF.
In case of obstruction of the radar
sensor (in this case the bumper area
where it is located must be cleaned).
If the system is set, the conditions
described above also cause a
cancellation or deactivation of the
system. These situations may vary
according to the conditions.
Note: The system will not be deactivated
when speeds higher than those set are
reached by pressing the accelerator
pedal above 110 mph (180 km/h). In
these situations, the system may not
work correctly and it is recommended to
deactivate it.
To Vary The Speed Setting
Increasing Speed
Once the system has been activated, you
can increase the speed by lifting the SET
switch. Each time it is operated, the
speed increases by 1 mph.
By holding the button up, the set speed
will increase in increments of 5 mph until

168
STARTING AND OPERATING

Warning!
The Resume function should only be used if
traffic and road conditions permit. Resuming
a set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to
follow these warnings can result in a collision
and death or serious personal injury.
Setting The Distance Between Vehicles
The distance between your vehicle and
the vehicle ahead may be set to one bar
(short), two bars (medium), three bars
(long), or four bars (maximum).
The distances from the vehicle ahead are
proportional to speed.
The interval of time with relation to the
vehicle ahead remains constant and
varies from one second (for the shortdistance one-bar setting) to two seconds
(for the maximum distance four-bar
setting).
The set distance is shown on the display
by a dedicated icon.
The setting is four (maximum) the first
time the system is used. After the
distance has been modified by the driver,
the new distance will be stored also after
the system is deactivated and
reactivated.
To Decrease The Distance
Push and release the distance button to
decrease the distance setting. The
distance setting decreases by one bar
(shorter) every time the button is pushed.
The set speed is held if there are no
vehicles ahead. Once the shortest
distance has been selected, the next push
of the button will set the maximum
distance.
If a slower vehicle is detected in the same
lane, the vehicle icon on the displayilluminates from grey to white. The
system automatically adjusts the
vehicle’s speed to keep the set distance,
independently of the set speed.
The vehicle holds the set distance until:
The vehicle ahead accelerates to a
speed higher than the set speed.
The vehicle ahead leaves the lane or
the detection field of the Adaptive Cruise
Control system sensor.
The distance setting is changed.
The Adaptive Cruise Control system is
deactivated/paused.
Warning!
The maximum breaking applied by the
system is limited. The driver may apply the
brakes in all cases if needed.
If the system predicts that the braking
level is insufficient to hold the set distance,
either “BRAKE!” or a dedicated message is
displayed to warn the driver of approaching
the vehicle ahead. An acoustic signal is also
emitted. In this case, it is advised to brake
immediately as necessary to hold a safe
distance from the vehicle ahead.
The driver is responsible for ensuring that
there are no pedestrians, other vehicles or
objectives along the direction of the vehicle.
Failure to comply with these precautions
may cause serious accidents and injuries.
