(Continued)
This very important section describes the safety
syst
e

ms that your vehicle may be equipped with,
and provides instructions on how to use them
correctly.
ACTIVE SAFETY SYSTEMS
The vehicle may be equipped with the following
active safety devices:
Anti-Lock Brake System (ABS)
Active Torque Vectoring (ATV)
Dynamic Steering Torque (DST)
Drive Train Control (DTC)
Electronic Stability Control (ESC)
Hill Start Assist (HSA)
Panic Brake Assist (PBA)
Traction Control System (TCS)
For the operation of the systems, see the
following pages.
ANTI-LOCK BRAKE SYSTEM (ABS)
An integral part of the braking system, the ABS
prevents one or more wheels from locking and
slipping in all road surface conditions, regardless
of the intensity of the braking action. The system
ensures that the vehicle can be controlled even
during emergency braking, allowing the driver to
optimize stopping distances.
The system intervenes during braking when the
wheels are about to lock, typically in emergency
braking or low-grip conditions where locking may
be more frequent. The system also improves control and stability of
the vehicle when braking on a surface where the
grip of the left and right wheels varies, such as in
a corner.
The Electronic Braking Force Distribution (EBD)
system works with the ABS, allowing the brake
force to be distributed between the front and rear
wheels.
System Intervention
The ABS equipped on this vehicle is provided with
the "Brake-by-wire" (Integrated Brake System —
IBS) function. With this system, the command
given by pressing the brake pedal is not
transmitted hydraulically, but electrically.
Therefore, the light pulsation that is felt on the
pedal with the traditional system is no longer
noticeable.
ACTIVE TORQUE VECTORING (ATV) —
I
F EQUIPPED
The dynamic drive control is used to optimize and
balance the drive torque between the wheels of
the same axles. The ATV system improves the grip
in turns, sending more drive torque to the
external wheel.
Given that, in a turn, the external wheels of the
car travel more than the internal ones and
therefore turn faster, sending a higher thrust to
the external rear wheel allows for the car to be
more stable and to not suffer an "understeer"
condition. Understeer occurs when the vehicle is
turning less than appropriate for the steering
wheel position.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to
interference caused by improperly installed
or high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead to
a collision. Pumping makes the stopping
distance longer. Just press firmly on your
brake pedal when you need to slow down or
stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.
WARNING!

130

DYNAMIC STEERING TORQUE (DST)
DST uses the integration of the Electronic
Stability Control (ESC) system with the electric
power steering to increase the safety level of the
whole vehicle.
In critical situations (braking on surfaces with
different grip conditions), the ESC system
controls the steering through the DST function to
implement an additional torque contribution on
the steering wheel in order to suggest the most
correct maneuver to the driver.
The coordinated action of the brakes and
steering increases the sensation of safety and
control of the vehicle.

NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly depen-
dent on the driver’s sensitivity and overall reac -
tion to the applied torque. It is very important to
realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.
DRIVE TRAIN CONTROL (DTC) SYSTEM —
I
F EQUIPPED
Some models of this vehicle are equipped with an
All-Wheel Drive (AWD) system, which offers an
optimal drive for countless driving conditions and
road surfaces. The system reduces the slipping of
the tires to a minimum, automatically
redistributing the torque to the front and rear
wheels as needed. To maximize fuel savings, the vehicle with AWD
automatically passes to Rear-Wheel Drive (RWD)
when the road and environmental conditions are
such that they wouldn't cause the tires to slip.
When the road and environmental conditions
require better traction, the vehicle automatically
goes to AWD mode.

NOTE:
If the system failure symbol switches on, after
starting the engine or while driving, it means that
the AWD system is not working properly. If the
warning message activates frequently, it is
recommended to carry out the maintenance
operations.
ELECTRONIC STABILITY CONTROL (ESC)
The ESC system improves the directional control
and stability of the vehicle in various driving
conditions.
The ESC system corrects the vehicle’s understeer
and oversteer, distributing the brake force on the
appropriate wheels. The torque supplied by the
engine can also be reduced in order to maintain
control of the vehicle.
Oversteer
occurs when the vehicle is turning
more than it should according to the angle of
the steering wheel.
Understeer occurs when the vehicle is turning
less than it should according to the angle of
the steering wheel.
The ESC system uses sensors installed on the
vehicle to determine the path that the driver
intends to follow and compares it with the
vehicle’s effective path. When the real path
deviates from the desired path, the ESC system
intervenes to counteract these conditions. System Intervention
The intervention of the system is indicated by the
flashing of the ESC Warning Light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
WARNING!

Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The
capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.

Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and
size or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade ESC
performance. Any vehicle modification or
poor vehicle maintenance that reduces the
effectiveness of the ESC system can
increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.

HILL START ASSIST (HSA)
This is an integral part of the ESC system and
facilitates starting on slopes, activating automat-
ically in the following cases:
Uphill: vehicle stationary on a road with a
gradient higher than 5%, engine running,
brake pressed and transmission in NEUTRAL
(N) or gear other than REVERSE (R) engaged.
Downhill: vehicle stationary on a road with a
gradient higher than 5%, engine running,
brake pressed and REVERSE gear engaged.
When starting to move forward from a complete
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.
PANIC BRAKE ASSIST (PBA)
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.
TRACTION CONTROL SYSTEM (TCS)
The TCS automatically operates in the event of
slipping, loss of grip on wet roads (hydroplaning),
and acceleration on one or both drive wheels on
roads that are slippery, snowy, icy, etc. Depending
on the slipping conditions, two different control
systems are activated:
If the slipping involves both drive wheels, the
system intervenes, reducing the power
transmitted by the engine.
If the slipping only involves one of the drive
wheels, the Brake Limited Differential (BLD)
function is activated, automatically braking the
wheel which is slipping (the behavior of a
self-locking differential is simulated). This will
increase the engine torque transferred to the
wheel which isn't slipping.
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. 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.

System Intervention
The intervention of the system is indicated by the
flashing of the ESC Warning Light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
AUXILIARY DRIVING
SYSTEMS
The following auxiliary driving systems are
available in this vehicle:
Forward Collision Warning (FCW)
Tire Pressure Monitoring System (TPMS)
Driver Attention Assist (DAA)
The vehicle may also be fitted with the following
driving assistance systems:
Blind Spot Monitoring (BSM)
Active Blind Spot Assist (ABSA)
Lane Departure Warning (LDW)
Lane Keeping Assist (LKA)
Highway Assist System (HAS)
Traffic Jam Assist (TJA)
Adaptive Cruise Control (ACC)
Intelligent Speed Control (ISC)
Traffic Sign Recognition (TSR)
For the operation of the LDW, LKA, HAS, TJA, ACC,
ISC, or TSR systems, see

Ú
page 81.

NOTE:
When driving on two-way roads where there is no
lane dividing center line (e.g. on unpaved roads),
the use of the Active Blind Spot Assist (ABSA), HAS, TJA, and LKA systems is strongly discour
-
aged as the system could detect the entire road
as single-lane dividing lines.

NOTE:
The driving assistance systems are designed to
aid in driving the car. The driver must always
maintain a sufficient level of attention to the
traffic and road conditions and control the trajec -
tory of the car.
BLIND SPOT MONITORING (BSM)
S
YSTEM — 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 presence
of other vehicles in the detection area by illumi -
nating 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). The sensors are temporarily deactivated when
the vehicle is stationary or the vehicle is in PARK.
The detection area of the system covers approxi -
mately 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
monitors the detection areas on both sides of the
vehicle and warns the driver about the possible
presence of vehicles in these areas.
23_GA_OM_EN_USC_t.book Page 132

133

While driving, the system monitors the detection
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 circum-
stances, 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.
If a trailer is hitched to the car, the system
automatically deactivates.
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 25 mph (40 km/h) in relation to your
vehicle.
Overtaking Vehicles

If another vehicle is overtaken slowly, with a
difference in speed of less than 15 mph (25 km/h)
and the vehicle stays in the blind spot for approxi
-
mately 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 15 mph (25 km/h), the
warning light does not illuminate

Ú
page 239.
Rear Cross Path Detection (RCP) System
The RCP 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 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.
For the system to operate correctly, the rear
fascia/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 fascia/bumper area
where the radar sensors are located with any
object (e.g. adhesives, bike rack, etc.). Operating Mode
The system may be activated/deactivated via the
radio system. To access the function, select the
following items on the main menu in sequence:
1. “Settings”
2. “Passive 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, indicating a lane
change.
The warning light will be constant if the driver
stays in the same lane.
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.
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.

134

(Continued)
“Blind Spot Alert” Function Deactivation
When the system is deactivated (“Blind Spot
Alert” mode off), the BSM or RCP systems will not
emit an audible or a 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 stored previously will be recalled and used.
ACTIVE BLIND SPOT ASSIST (ABSA)
S
YSTEM — IF EQUIPPED
The Active Blind Spot Assist (ABSA) system
function is to help avoid/limit lateral collisions
with cars located in the blind spot zones, even
changing the vehicle’s trajectory in order to keep
it in the detected lane.
The system warns the driver about the presence
of other vehicles in the detection area by illumi -
nating the warning light located within the door
mirror on the side in which the other vehicle was
detected. The system will also provide an
acoustic signal and/or vibration on the steering
wheel and/or counter-steering torque on the
steering wheel (if the respective item on the
“Driver Assistance” menu is set up and “Safety”
is selected on the radio system).
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active (the warning light comes on even
if the system is activated through the radio
system menu). ABSA Indicator Light
Sensors
The system uses two radar sensors, located in
the rear fascia/bumper (one for each side) to
detect the presence of vehicles (cars, trucks,
motorbikes, etc.) in the rear side blind spots of
the car.
The sensors are activated when any forward gear
is engaged at a speed higher than about 6 mph
(10 km/h), or when REVERSE (R) is engaged.
The sensors are temporarily deactivated when
the car is stationary and in PARK (P).
The detection area of the system covers about a
lane on both sides of the car around 10 ft (3 m).
This area begins from the door mirror and
extends for about 20 ft (6 m) towards the rear
part of the car.
When the sensors are active the system monitors
the detection areas on both sides of the car and
warns the driver about the possible presence of
cars in these areas.
WARNING!
The accident risk persists despite the
application of torque to the steering wheel by
the ABSA system.
Applying a torque that corrects the steering
wheel alignment does not always prevent an
accident. It is always the driver's responsi
-
bility to steer, brake or accelerate, especially
after the ABSA system warning or after the
steering wheel torque intervention. The
driver is responsible for ensuring that there
are no pedestrians, other vehicles or objects
along the direction of the vehicle. Failure to
comply with these precautions may cause
serious accidents and injuries. The driver is
fully responsible for holding a safe distance
from the vehicle ahead respecting the
highway code in force in the respective
country.
In some cases, the system could apply an
improper torque to the steering wheel. This
application can be interrupted at anytime
turning the steering wheel in the opposite
direction.

FORWARD COLLISION WARNING PLUS
(FCW+) S
YSTEM — IF EQUIPPED
This is a driving assistance system composed of
a radar located behind the front fascia/bumper
and a camera located in the center of the
windshield.
Front Fascia/Bumper Radar Location
Windshield Camera Location In the event of an imminent collision, the system
intervenes by automatically applying the vehicle’s
brakes to prevent a the collision or reduce its
effects.
The system provides the driver with audible and
visual signals through specific messages on the
instrument cluster display.
Vehicle Brake Screen
Pedestrian Brake Screen The system may lightly brake to warn the driver if
a potential front end collision is detected (limited
braking). Signals and limited braking are
intended to allow the driver time to intervene.
In situations with the risk of collision, if the
system detects no intervention by the driver, it
provides automatic braking to help slow the
vehicle and mitigate the potential front end
collision (automatic braking). If intervention by
the driver on the brake pedal is detected, but not
deemed sufficient, the system may intervene in
order to improve the reaction of the braking
system by reducing vehicle speed further
(additional assistance in braking stage).

The system will intervene automatically in case of
imminent collision or impact against a pedestrian
crossing the road (speed under 31 mph (50 km/h)).

NOTE:
For safety reasons, when the vehicle has
stopped, the brake calipers may remain blocked
for about two seconds. Make sure to press the
brake pedal if the vehicle moves slightly forward.
WARNING!
Forward Collision Warning (FCW) is not
intended to avoid a collision on its own, nor
can FCW detect every type of potential
collision. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.
23_GA_OM_EN_USC_t.book Page 138

139

Engagement/Disengagement
The system may be disengaged (and engaged
again) in the “Driver Assistance” menu of the
Information and Entertainment System.
The system can be deactivated even with the
ignition device in the ON position.

NOTE:
The system status can be changed with car at a
standstill only.
Select from among three operating modes:
Warning And Braking: the system (if active), in
addition to the visual and audible warnings,
provides limited braking, automatic braking,
and additional assistance in braking stage
where the driver does not brake sufficiently in
the event of a potential front-end collision.
Only Warning : the system (if active), does not
provide limited braking, but guarantees
automatic braking or additional assistance in
braking stage where the driver does not brake
at all or not sufficiently enough in the event of
a potential front-end collision.
Disabled : the system does not provide visual
and audible warnings, limited braking,
automatic braking, or additional assistance in
braking stage. The system will therefore
provide no indication of a possible collision.
Activation/Deactivation
The Forward Collision Warning system is
activated whenever the engine is started
regardless of what is shown on the radio system.
Following a deactivation, the system will not warn
the driver about the possible collision with the
preceding vehicle, regardless of the setting
selected with the radio system.

NOTE:
Each time the engine is started, the system is
activated regardless of what setting was selected
when the engine was turned off.
The system is active:
Each time the engine is started
In the radio system
When the ignition is in the ON position
When the vehicle speed is between 2 mph
(4 km/h) and 124 mph (200 km/h)
When the front seat belts are fastened

NOTE:
If the seat belts of the front seats are not correctly
fastened, the system will not intervene 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 collision
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.

NOTE:
The “Far” setting may result in a greater number
of FCW possible collision warnings experienced.
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.

NOTE:
The “Near” setting may result in a lesser number
of FCW possible collision warnings experienced.
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 condition
limiting the system operation may have occurred.
The possible reasons of this limitation 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
functions end, this will go back to normal and
complete operation. Should the fault persist,
contact an authorized dealer.

SAFETY

142

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The vehicle is equipped with a 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. The TPMS uses wireless technology with wheel
rim mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure
readings to the receiver module.
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. The tire pressure will also
increase as the vehicle is driven. This is normal,
and there should be no adjustment for this
increased pressure. See

Ú
page 206 for
information on how to properly inflate the
vehicle’s tires.
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 System 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.

NOTE:
The TPMS cannot indicate sudden tire pressure
drops (e.g. if a tire bursts). In this case, proceed
with caution and avoid abrupt steering.
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 System Warning
Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring
System Warning Light will still be on. In this
situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold
placard pressure value.
WARNING!
The system has not been designed to
prevent impacts and cannot detect possible
conditions leading to an accident in
advance. Failure to take into account this
warning may lead to serious or fatal injuries.
The system may activate, assessing the
trajectory of the vehicle, for the presence of
reflecting metal objects different from other
vehicles, such as safety barriers, road signs,
barriers before parking lots, tollgates, level
crossings, gates, railways, objects near road
constructions sites or higher than the vehicle
(e.g. a fly-over). In the same way, the system
may intervene inside multi-story parking lots
or tunnels, or due to a glare on the road
surface. These possible activations are a
consequence of the real driving scenario
coverage by the system and must not be
regarded as faults.
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 deacti
-
vation is signaled by the dedicated warning
light/symbol switching on in the instrument
panel

143

Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the Tire Pressure Monitoring
System Warning Light in the instrument cluster
will display alongside the dedicated messages,
the system will highlight the tire or tires with
insufficient pressure graphically, and an acoustic
signal will be emitted.In this case, stop the vehicle, check the inflation
pressure of each tire, and inflate the necessary
tire or tires to the correct cold inflation pressure
value, shown on the display or in the dedicated
TPMS menu.
TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds, and then remain
on solid. The system fault will also sound a chime.
If the ignition is cycled, this sequence will repeat,
provided that the system fault still exists. The Tire
Pressure Monitoring System Warning Light will
turn off when the fault condition no longer exists.
A system fault can occur due to any of the
following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Packed snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
After the punctured tire has been repaired with
the original tire sealant contained in the tire kit,
the previous condition must be restored so that
the Tire Pressure Monitoring System Warning
Light is off during normal driving.
TPMS Deactivation
The TPMS can be deactivated by replacing all four
wheel and tire assemblies (road tires) with wheel and tire assemblies that do not have TPMS
sensors, such as when installing winter wheel
and tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
System sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds
and then remain on. The instrument cluster will
display the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the
pressure values.
Beginning with the next ignition switch cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster. Instead, dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPMS sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then turn off.
The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display
pressure values in place of the dashes. On the
next ignition switch cycle the "SERVICE TPM
SYSTEM" message will no longer be displayed, as
long as no system fault exists.

NOTE:

The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the
tire size equipped on your vehicle.
Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type,
and/or style. The TPMS sensor is not
designed for use on aftermarket wheels and
may contribute to a poor overall system
performance or sensor damage. Customers
are encouraged to use Original Equipment
Manufacturer (OEM) wheels to ensure proper
TPMS feature operation.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
