“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) System — 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 pres-
ence of other vehicles in the detection area by
illuminating 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 selecting "Safety" 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 meters).
This area begins from the door mirror and
extends for about 20 ft (6 meters) towards the
rear part of the car. 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 respon
-
sibility to steer, brake or accelerate, espe -
cially after the ABSA system warning or
after the steering wheel torque interven -
tion. The driver is responsible for ensuring
that there are no pedestrians, other vehi -
cles 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.

NOTE:

If the safety belts of the front seats are not
correctly fastened, the system will not inter-
vene 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 colli -
sion 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.
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. 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 condi
-
tion limiting the system operation may have
occurred. The possible reasons of this limita -
tion 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 func -
tions end, this will go back to normal and
complete operation. Should the fault persist,
contact an authorized dealer.
System Failure Signaling
If the system turns off and a dedicated
message is shown on the display, it means
that there is a fault with the system.
In this case, it is still possible to drive the
vehicle, but you are advised to contact an
authorized dealer as soon as possible.
Radar Indication Not Available
If conditions are such that the radar cannot
detect obstacles correctly, the system is deac -
tivated and a dedicated message appears on
the display. This generally occurs in the event
of poor visibility, such as when it is snowing or
raining heavily. The function of this system can also be tempo
-
rarily reduced due to obstructions such as
mud, dirt or ice on the fascia/bumper. In such
cases, a dedicated message will be shown on
the display and the system will be deactivated.
This message can sometimes appear in condi -
tions of high reflectivity (e.g. tunnels with
reflective tiles or ice or snow). When the condi -
tions limiting the system functions end, it will
go back to normal and complete operation.
In certain cases, this dedicated message
could be displayed when the radar is not
detecting any vehicles or objects within its
view range.
If atmospheric conditions are not the reason
behind this message, check if the sensor is
dirty. It could be necessary to clean or remove
any obstructions in the area.

If the message appears frequently, even in the
absence of atmospheric conditions such as
snow, rain, mud or other obstructions, contact an
authorized dealer for a sensor alignment check.

In the absence of visible obstructions, manu -
ally removing the decorative cover trim and
cleaning the radar surface could be required.
Have this operation performed at an autho -
rized dealer.

NOTE:

It is recommended that you do not install
devices, accessories, or aerodynamic attach -
ments in front of the sensor or darken it in any
way, as this can compromise the correct func -
tioning of the system.

Vehicles Traveling At Right Angles To The
Vehicle
The system may temporarily react to a vehicle
that is passing through the radar sensor’s
operating range at right angles.Other Vehicle Passing Through Radar RangeTire 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 pres -
sure 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 234 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.
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 conse -
quence 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
Ú
page 73.
WARNING! (Continued)
21_GA_OM_EN_USC_t.book Page 156

157

The TPMS will stop indicating insufficient tire
pressure when pressure is equal to or greater
than the prescribed cold inflation level. There-
fore, if insufficient tire pressure is indicated by
the ( ) warning light displaying in the instru -
ment 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 pres -
sure 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.

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 infla
-
tion pressure of each tire, and inflate the
necessary tire or tires to the correct cold infla -
tion pressure value, shown on the display or in
the dedicated TPMS menu.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished 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 after -
market wheels and may contribute to a
poor overall system performance or
sensor damage. Customers are encour -
aged to use Original Equipment Manufac -
turer (OEM) wheels to assure 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 pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.

TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the Tire Pres-
sure 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 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 Moni
-
toring System sensors. Then, drive the vehicle
for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS 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 pres -
sure 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 TPMS
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 igni
-
tion 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.

The TPMS should not be used as a tire pres -
sure gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire will
cause the tire to overheat, and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.

The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
underinflation has not reached the level to
trigger illumination of the Tire Pressure
Monitoring System Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire

How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal circuits
and interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:

Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC posi -
tion, the air bag system is not on and the air
bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.

The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch
is first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of
the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single
chime will sound to alert you if the light comes on
again after initial startup.

The ORC also includes diagnostics that will illu -
minate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While
the air bag system is designed to be mainte - WARNING!
The seat belt assembly must be replaced
if the switchable Automatic Locking
Retractor (ALR) feature or any other seat
belt function is not working properly when
checked according to the procedures in
the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in colli-
sions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.

Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or roll -
over 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 Occupant Restraint Controller (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.
Supplemental Driver And Front Passenger
Knee Air Bags
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column and a
Supplemental Passenger Knee Air Bag
mounted in the instrument panel below the
glove compartment. The Supplemental Knee
Air Bags provide enhanced protection during a
frontal impact by working together with the
seat belts, pretensioners, and front air bags.
Driver Knee Air Bag
Front Passenger Knee Air Bag
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights,
stereos, citizen band radios, etc.
21_GA_OM_EN_USC_t.book Page 168

The Side Air Bags and seat belt pretensioners
will not deploy in all rollover events. The roll-
over sensing system determines if a rollover
event may be in progress and whether deploy -
ment is appropriate. In the event the vehicle
experiences a rollover or near rollover event,
and deployment is appropriate, the rollover
sensing system will deploy the side air bags
and 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 irri -
tate 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 manufac -
turer’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.

NOTE:

Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
WARNING!

Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have
the air bags, seat belt pretensioners, and the
seat belt retractor assemblies replaced by an
authorized dealer immediately. Also, have the
Occupant Restraint Controller System
serviced as well.
