(Continued)
This very important section describes the safety
systems 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) System
Dynamic Steering Torque (DST) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC) System
Hill Descent Control (HDC) System
Hill Start Assist (HSA) System
Panic Brake Assist (PBA) System
Traction Control System (TCS)
For system operation, 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)
S
YSTEM — IF 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.

DYNAMIC STEERING TORQUE (DST)
S
YSTEM
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 (e.g. braking on surfaces with
different grip conditions), the ESC system
influences 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 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
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 tire slipping 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
switches to AWD mode.

NOTE:

There may be a brief delay in shifting to AWD
mode after a tire slipping event occurs.
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)
S
YSTEM
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.
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 counter the vehicle’s oversteer or
understeer.
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.
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.

HILL DESCENT CONTROL (HDC)
S
YSTEM — IF EQUIPPED
The HDC function is an integral part of the
Electronic Stability Control (ESC) system, keeping
the vehicle at a constant speed while descending
a hill by actively controlling the brakes.
HDC aims to create vehicle stability and safer
driving in various situations, including poor grip
conditions and steep descents.
The system has three different modes:
Off: the system is deactivated
Enabled: the system is enabled and ready to
intervene when the activation conditions are
met
Active: the system actively controls the vehicle
speed Enabling The System
To enable the system, push the HDC switch
located on the steering wheel.
HDC Switch
The system is enabled if the car speed is below
20 mph (30 km/h). The system stays enabled
until the car speed reaches 37 mph (60 km/h),
the system is disabled at speeds above 37 mph
(60 km/h).
Activation of the HDC system is indicated by the
white icon appearing in the instrument cluster
display.
HDC Symbol Activation Of The System
Once enabled, the HDC system will activate
automatically if the vehicle is driven on a downhill
slope with sufficient gradient, greater than 8%.
The speed set for the HDC system can be
adjusted using the SET switch located on the
steering wheel.
HDC Speed SET Switch
Once the desired speed has been reached,
release the SET switch and the HDC system will
maintain the set speed. After set speed is
established, the HDC system will automatically
brake to keep the vehicle at the set speed if the
accelerator pedal is released and the vehicle gets
close to the set speed.
It is possible to reduce the set speed with the
brake pedal. When the pedal is released, the
system will adjust the set speed to the new
current speed.
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.

(Continued)
Rear Cross Path Detection (RCP) System
The Rear Cross Path Detection (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 approximately 1 mph
(1 km/h) and 2 mph (3 km/h) and objects moving
at a maximum speed of 21 mph (35 km/h), in
areas such as parking lots.

The system activation is signaled to the driver by
an audible warning.

NOTE:

If the sensors are covered by objects or
vehicles, the system may not work as intended.
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. “Driving Assistance”
2. “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.
“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

Ú

ACTIVE BLIND SPOT ASSIST (ABSA)
S
YSTEM — IF EQUIPPED
The ABSA system is to help avoid/limit lateral
collisions with cars coming from adjacent lanes
changing the vehicle’s trajectory in order to try 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 and by means of 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 then “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
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 park -
ing 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 pedestri -
ans, animals, other vehicles, obstructions, and
blind spots before backing up. Failure to do so
can result in serious injury or death.
WARNING!
The accident risk persists despite the
application of torque to the steering wheel by
the ABSA system.
22_GU_OM_EN_USC_t.book Page 141

SAFETY

142

Sensors
The system uses radar sensors, located in the
rear fascia/bumper, 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 meters).This area begins from the door mirror and
extends for about 20 ft (6 meters) 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.
Rear Sensor Location
While driving, the system monitors the 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;
to check if it is necessary to intervene in order to
keep the vehicle inside the lane on both sides.

NOTE:
The system does not signal the presence of fixed
object (e.g. safety barriers, poles, walls, etc.).
However, in some circumstances, the system
may activate in the presence of these
objects.This is normal and does not indicate a
system malfunction. The system does not warn the driver about the
presence of cars coming from the opposite direc
-
tion, in the adjacent lanes.
Activation/Deactivation
The system can be activated/deactivated using
the “Driver Assistance” menu in the radio system.
Select signal type, strength levels and sensitivity.

NOTE:
Vehicles with an active system will display the
following screen, on the radio system.
ABSA Menu Screen
System Intervention
The system intervenes in the following
conditions:
the turn signals have been activated;
there is a vehicle in the adjacent lane on the
same side of the turn signal (blind spot area);
lane lines are not correctly detected;
the driver tries to change lanes intentionally.
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 any time by
turning the steering wheel in the opposite
direction.
WARNING!
22_GU_OM_EN_USC_t.book Page 142

143

If the system detects the presence of a vehicle in
the rear side blind spots of the car, it applies a
torque on the steering wheel (if it has been set
through the “Settings” menu of the radio system),
in order to warn the driver of the need to keep the
car inside the lane and thus avoid collisions with
other vehicles.
The application of torque and vibration is
however only available with car speed between
37 mph (60 km/h) and 110 mph (180 km/h).
The application of torque, as well as of the
vibration, is suppressed/inhibited if:
The torque given by the driver of the steering
wheel is high
Lateral acceleration is high
The trailer is connected to the correct control
module
At least one hand is not detected on the
steering wheel for longer than a specific time
The turn signal is turned off

NOTE:
The steering wheel torque is not applied if the
system is unable to detect a lane and if the turn
signal for the appropriate side has not been
switched on.
The steering wheel detects the presence of the
driver’s hands by a capacitive sensor installed in
the steering wheel and by the applied torque
measured on the steering column.System Availability
Aggressive driving of the car, or driving on the
median lines, will prevent the correct operation of
the system.
In case of intervention of the stability and braking
systems (FCW, ESC, ABS) they will prevent the
system from operating.
Lane change will disable the system for a certain
period of time.
The road must also comply with some specific
characteristics, such as:
Maximum/minimum lane width.
Clearly identified and defined double yellow
lines and, for a limited period of time, a lane
with a single demarcation line.

NOTE:
In some cases, for a limited period of time, the
system may be activated by a lane with a single
median line.
In cases of good road surface conditions, the
system could correctly recognize other types of
valid lane markings (e.g. road edges, sidewalks,
etc.).
Hand Presence On The Steering Wheel Detection
The system is able to detect the presence of the
driver’s hands on the steering wheel.
When the system does not detect the presence of
hands on the steering wheel for 0 to 6 seconds,
the following screen will be displayed on the
instrument cluster display. No acoustic warning
will be emitted in this case.
Hand Presence On The Steering Wheel Not
Detected Display (Up To 6 Seconds)
When the system does not detect the presence of
hands on the steering wheel from 6 to 15 sec-
onds, the following screen will be displayed on
the instrument cluster display. A short acoustic
signal will sound if hands are not detected on the
steering wheel for 6 to 12 seconds. A continuous
signal will sound if hands are not detected on the
steering wheel for 12 to 15 seconds.
Hand Presence On The Steering Wheel Not Detected Display (6 To 15 Seconds)
22_GU_OM_EN_USC_t.book Page 143

SAFETY

144

After 15 seconds with the hands removed from
the steering wheel, the LKA system will be
deactivated and a dedicated message will be
shown on the instrument cluster display. A short
acoustic signal will sound in this case.
In any of the situations above where the hands
are removed from the steering wheel for more
than 6 seconds, it is necessary to reposition the
hands on the steering wheel.
Changing The System Sensitivity
The system's sensitivity can be set through the
radio system. Select the “Driver Assistance”
menu and then select “Comfort”. Sensitivity
“High” or “Low” can be selected.
Rear Cross Path Detection (RCP) System
The Rear Cross Path Detection (RCP) system
assists the driver during reverse maneuvers in
the case of reduced visibility.

When the ABSA system is active, the RCP system
monitors the rear detection areas on both sides of
the vehicle to detect objects moving towards the
sides of the vehicle at a minimum speed between
0.6 mph and 2 mph (1 km/h and 3km/h) from
objects moving at a maximum speed of 22 mph
(35 km/h).

These are generally occurrences that happen in
parking areas.
The system activation is signaled to the driver by
means of a visual and audible warning.

NOTE:
If the sensors are covered by objects or vehicles,
the system may not work as intended.Changing The System Sensitivity
To change the sensitivity and the strength of the
torque intervention on the steering wheel, refer to
“Settings” of the radio system

DRIVER ATTENTION ASSIST (DAA)
S
YSTEM — IF EQUIPPED
The Driver Attention Assist (DAA) system detects
when the driver is feeling fatigued and warns the
driver to pull over and take a break.
To Activate/Deactivate
The DAA system can be activated and
deactivated through the radio system by
selecting the following in order:
1. “Driver Assistance”
2. “Driver Attention Assist”
System Intervention
Using information from the front camera, the
system implements two operating logics:
The first operating logic takes the driving style
into account, observing the road and detecting
to what extent the driver can continue driving
with few lane crossing events.
The second operating logic measures the time
spent behind the wheel with the vehicle speed
above 40 mph (60 km/h) and below 110 mph
(180 km/h). If the “Standard” option is
selected, in these conditions, the “Dozy Driver”
message may appear after three hours of
driving. If the “Early” option is selected and
these conditions occur, the “Dozy Driver”
message will be displayed after two hours of
driving.

NOTE:
If the conditions described above are not
detected continuously during the entire driving
period, the “Dozy Driver” message may be
displayed later than two or three hours. If the
driving style indicates that the driver is unable to
follow the road trajectory and respect the hori-
zontal lane markings, the red symbol will appear
on the instrument cluster display to suggest that
the driver should stop for a break. An audible
signal will also sound.
If the driver accepts the suggestion provided by
the system by pushing the MENU button on the
multifunction lever, the message will disappear
from the display and the symbol will be displayed
in the dedicated area of the instrument cluster
display until the next engine shutdown. WARNING!
The DAA System is an aid for driving and does
not relieve the driver of the responsibility of
driving the vehicle. If you experience fatigue
while driving, pull over safely for a break
without waiting for the DAA to intervene. Only
return to the road when you are in the right
physical and mental condition to prevent
endangering yourself and other drivers.
22_GU_OM_EN_USC_t.book Page 144

SAFETY

146

Pedestrian Brake Screen
The audible and visual signals warn the driver
before the system activates, depending on the
vehicle speed.

NOTE:
No warning signals are generated at speeds
below 20 mph (30 km/h).
The system may lightly brake to warn the driver if
a possible frontal accident is detected (limited
braking). Signals and limited braking are
intended to allow the driver to react promptly, in
order to prevent or reduce the effects of a
potential accident.
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 frontal 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,
therefore 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.
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 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 the braking stage,
where the driver does not brake sufficiently in
the event of a potential frontal impact.
Only Warning : the system (if active), does not
provide limited braking, but guarantees
automatic braking or additional assistance in
the braking stage, where the driver does not
brake at all or not sufficiently in the event of a
potential frontal impact.
Disabled : the system does not provide visual
and audible warnings, limited braking,
automatic braking or additional assistance in
the 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 a
preceding vehicle, regardless of the setting
selected in 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.
This function is not active at a speed lower than
4 mph (7 km/h) or higher than 124 mph
(200 km/h).
The system is active:
Each time the engine is started
When feature is selected within 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)
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.
22_GU_OM_EN_USC_t.book Page 146

SAFETY

148

Frontal Collision Alarm With Active Braking — If
Equipped
If this function is selected, the brakes are
operated to reduce the speed of the vehicle in the
event of potential frontal impact.
This function applies an additional braking
pressure if the braking pressure applied by the
driver does not suffice to prevent potential frontal
impact.
The function is active with speed above 2 mph
(4 km/h).

NOTE:
When using an automatic car wash it is recom-
mended to deactivate the system through the
settings of the radio system. The system may
detect the presence of a car, a wall or another
obstacle and activate.
Driving In Special Conditions
In certain driving conditions, system intervention
might be unexpected or delayed. The driver must
therefore be very careful, keeping control of the
vehicle to drive in complete safety.
Driving close to a bend.
The vehicle ahead is leaving a roundabout.
Vehicles with small dimensions and/or not
aligned in the driving lane.
Lane change by other vehicles.
Vehicles traveling at right angles to the vehicle.

NOTE:

In particularly complex traffic conditions, the
driver can deactivate the system manually
through the Information and Entertainment
system.
If the driver presses the brake pedal fully or
makes an excessive steering maneuver during
system operation, the automatic braking
function may deactivate (e.g. to allow a
possible maneuver to avoid the obstacle).
The FCW system is automatically deactivated
when operating in race mode and a warning
message will be displayed on the instrument
cluster.
Driving Close To A Bend
When entering or leaving a wide bend, the system
may detect a vehicle in front of you, but not
driving in the same driving lane. In cases such as
these, the system may intervene.
Driving Around Wide Curves The Vehicle Ahead Is Leaving A Roundabout
On a roundabout, the system could intervene
when it detects a vehicle ahead that is leaving the
roundabout.
Driving In Roundabouts
Vehicles With Small Dimensions And/Or Not
Aligned In The Driving Lane
The system cannot detect vehicles in front of the
vehicle if they are outside the range of the radar
sensor and may not react to small vehicles, such
as bicycles or motorcycles.
Driving Near Small Vehicles

150

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
TPMS 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 Warning Light. Driving the
vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the TPMS
Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires
are inflated to the vehicle’s recommended cold
placard pressure value.
Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the 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 TPMS
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 TPMS 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 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.
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
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.
