SAFETY167
NOTE:In a parking lot situation, oncoming vehicles can be
blocked by vehicles parked on either side. If the sensors
are blocked by other structures or vehicles, the system will
not be able to alert the driver.
Modes Of Operation
Blind Spot has three selectable modes of operation that
are available in the Uconnect system.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM system
will provide a visual alert in the appropriate side view
mirror based on a detected object. However, when the
system is operating in RCP mode, the system will respond
with both visual and audible alerts when a detected object
is present. Whenever an audible alert is requested, the
radio volume is reduced so that the alert can be better
heard. Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the
appropriate side view mirror based on a detected object.
If the turn signal is then activated, and it corresponds to
an alert present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn signal and
detected object are present on the same side at the same
time, both the visual and audio alerts will be issued. In
addition to the audible alert the radio (if on) volume will be
reduced so that the alert can be better heard.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio
volume is reduced so that the alert can be better heard.
Blind Spot Alert Off
When the BSM system is turned off there will be no visual
or audible alerts from either the BSM or RCP systems.NOTE:The BSM system will store the current operating mode
when the vehicle is shut off. Each time the vehicle is
started the previously stored mode will be recalled and
used.
FORWARD COLLISION WARNING (FCW)
O
PERATION — IF EQUIPPED
FCW with Mitigation provides the driver with audible
warnings and visual warnings (within the instrument
cluster display) to warn the driver when it detects a
potential frontal collision. The warnings are intended to
provide the driver with enough time to react, avoid or
mitigate the potential collision.
NOTE:FCW monitors the information from the forward looking
sensors as well as the Electronic Stability Control (ESC)
system, to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings.

FCW Message

WARNING!
Rear Cross Path Detection (RCP) is not a backup 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.

(Continued)
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
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
Úpage 253 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(TPMS Warning Light) illuminates, you must increase the
tire pressure to the recommended cold placard pressure
in order for the TPMS Warning Light to turn off. 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:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 23 psi
(158 kPa). This tire pressure is sufficiently low enough to
turn on the TPMS Warning Light. Driving the vehicle may
cause the tire pressure to rise to approximately 27 psi
(186 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
Úpage 284.
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 pressure gauge
while adjusting your tire pressure, unless your vehicle
is equipped with a Tire Fill Alert (TFA) system.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
CAUTION!
 The TPMS has been optimized for the original equip -
ment 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 equip -
ment 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 encouraged to use Original Equipment Manufac -
turer (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 mois -
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
CAUTION!

Premium System
The Tire Pressure Monitoring System (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.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
 Four Tire Pressure Monitoring System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
 Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. In addition, the
instrument cluster will display an “Inflate to XX” message
and a graphic showing the pressure values of each tire
with the low tire pressure values shown in a different color.

Tire Pressure Monitoring System Display

Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
shown in a different color in the instrument cluster
graphic) to the vehicle’s recommended cold placard
pressure inflation value as shown in the “Inflate to XX”
message. Once the system receives the updated tire
pressures, the system will automatically update, the
graphic display in the instrument cluster will change color
back to the original color, and the TPMS Warning Light will
turn off. 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:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.

Low Tire Pressure Monitoring System Display

Service Tire Pressure System Warning
If a system fault is detected, the Tire Pressure Monitoring
System (TPMS) Warning Light will flash on and off for
75 seconds and then remain on solid. The system fault will
also sound a chime. In addition, the instrument cluster will
display a "Service Tire Pressure System" message for a
minimum of five seconds and then display dashes (- -) in
place of the pressure value to indicate which sensor is not
being received.

23_LA_OM_EN_USC_t.book Page 170

SAFETY171
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the TPMS Warning Light will no longer flash,
and the "Service Tire Pressure System" message will no
longer display, and a pressure value will display in place of
the dashes. A system fault can occur due to any of the
following:
Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies
as the TPMS sensors
 Accumulation of snow or ice around the wheels or
wheel housings
 Using tire chains on the vehicle
 Using wheels/tires not equipped with TPMS sensors
Vehicles With Compact Spare

1. The compact spare tire or non-matching full size does not have a Tire Pressure Monitoring System
sensor. Therefore, the TPMS will not monitor the
pressure in the compact or non-matching full size
spare tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key cycle, the TPMS Warning Light will remain
on and a chime will sound. In addition, the graphic in
the instrument cluster will still display a different
color pressure value and an "Inflate to XX" message. 3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the TPMS Warning Light will flash
on and off for 75 seconds and then remain on solid.
In addition, the instrument cluster will display a
“Service Tire Pressure System” message for five
seconds and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “Service Tire
Pressure System” message for five seconds and then
display dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact
spare or non-matching full size, the TPMS will update
automatically. In addition, the TPMS Warning Light
will turn off and the graphic in the instrument cluster
will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires. 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.TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can be
deactivated if 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 (TPMS) 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 Tire Pressure
System” message and then display dashes (--) in place of
the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “Service Tire Pressure System”
message in the instrument cluster but 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
Tire Pressure System” message and then display pressure
values in place of the dashes. On the next ignition cycle
the "Service Tire Pressure System" message will no longer
be displayed as long as no system fault exists.

If the passenger seating position is equipped with an ALR
and is being used for normal usage, only pull the seat belt
webbing out far enough to comfortably wrap around the
occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the
occupant’s mid-section. Slide the latch plate into the
buckle until you hear a "click."
In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still retract to
remove any slack in the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is installed in a
seating position that has a seat belt with this feature.
Children 12 years old and under should always be properly
restrained in the rear seat of a vehicle with a rear seat. How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.

2. Grab the shoulder portion and pull downward until
the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode.
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)
All passenger occupants within the vehicle must be in a
seat equipped with a Seat Belt System and Head Restraint
for the safety of the passenger.
If the front passenger and/or rear seats have been
removed do not ride in those areas.
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 System Components
 Occupant Restraint Controller (ORC)
 Air Bag Warning Light
 Steering Wheel and Column
 Instrument Panel
 Knee Impact Bolsters
 Driver and Front Passenger Air Bags
 Seat Belt Buckle Switch
 Supplemental Side Air Bags
 Front and Side Impact Sensors
 Seat Belt Pretensioners
 Seat Track Position Sensors
WARNING!
Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
 Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.
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 collisions.
 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.

SAFETY179
NOTE:Vehicles with the front passenger seat deleted will not be
equipped with the Seat Belt Buckle Switch, Seat Belt
Pretensioner, Supplemental Seat Mounted Side Airbag,
and Seat Track Position Sensors for the front passenger.
All passenger occupants within the vehicle must be in a
seat equipped with a Seat Belt System and Head Restraint
for the safety of the passenger.
If the front passenger and/or rear seats have been
removed do not ride in those areas.
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
position, 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 illuminate 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 maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.

The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
 The Air Bag Warning Light remains on after the four to
eight-second interval.
 The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine related
gauges are not working, the Occupant Restraint Controller
(ORC) may also be disabled. In this condition the air bags
may not be ready to inflate for your protection. Have an
authorized dealer service the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag Warning
Light has come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on intermittently
or remains on while driving have an authorized dealer
service the vehicle immediately
Úpage 63.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.

Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are
a supplement to the seat belt restraint systems. The driver
front air bag is mounted in the center of the steering
wheel. The passenger front air bag is mounted in the
instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on the air
bag covers.

Front Air Bags/Knee Impact Bolster Locations

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.

2 — Driver Knee Impact Bolster
3 — Passenger Knee Impact Bolster
WARNING!
 Being too close to the steering wheel or instrument
panel during front air bag deployment could cause
serious injury, including death. Air bags need room to
inflate. Sit back, comfortably extending your arms to
reach the steering wheel or instrument panel.
 Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
 Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.
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 colli -
sions, air bags won’t deploy at all. Always wear your
seat belts even though you have air bags.

23_LA_OM_EN_USC_t.book Page 180

SAFETY181
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 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 Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs
are marked with “SRS AIRBAG” or “AIRBAG” on a label or
on the seat trim on the outboard side of the seats.
The SABs may help to reduce the risk of occupant injury
during certain side impacts, in addition to the injury
reduction potential provided by the seat belts and body
structure.

Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB
deploys through the seat seam into the space between the
occupant and the door. The SAB moves at a very high
speed and with such a high force that it could injure
occupants if they are not seated properly, or if items are
positioned in the area where the SAB inflates. Children are
at an even greater risk of injury from a deploying 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.
WARNING!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the performance
could be adversely affected and/or objects could be
pushed into you, causing serious injury.
