WARNING!
other vehicles, obstructions, and blind
spots before backing up. Failure to do so
can result in serious injury or death.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
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 de-
tected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and
audible alerts when a detected object is pres-
ent. Whenever an audible alert is requested,
the radio is muted.
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 mirrorbased 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. When-
ever a turn signal and detected object are
present on the same side at the same time,
both the visual and audible alerts will be
issued. In addition to the audible alert the
radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
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 is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
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 oper-
ating 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) With
Mitigation — If Equipped
Forward Collision Warning (FCW) With Miti-
gation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with au-
dible warnings, visual warnings (within the
instrument cluster display), and may apply a
brake jerk to warn the driver when it detects a
potential frontal collision. The warnings and
limited braking are intended to provide the
driver with enough time to react, avoid or
mitigate the potential collision.
NOTE:
FCW monitors the information from the for-
ward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the prob-
ability of a forward collision. When the sys-

The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will
turn off once the system receives the updated
tire pressures. The vehicle may need to be
driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TPMS to receive
this information.
For example, your vehicle may have a recom-
mended 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 approxi-
mately 24 psi (165 kPa). This tire pressure is
low enough to turn ON the “Tire Pressure
Monitoring Telltale Light.” Driving the vehicle
may cause the tire pressure to rise to approxi-
mately 28 psi (193 kPa), but the “Tire Pres-
sure Monitoring Telltale Light” will still be on.
In this situation, the “Tire Pressure Monitor-
ing Telltale Light” will turn off only after the
tires are inflated to the vehicle’s recom-
mended cold placard pressure value.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 plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
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 opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. The
TPM sensor is not designed for use on
aftermarket wheels, and may contribute
to a poor overall system performance.
Customers are encouraged to use OEM
wheels to assure TPMS feature operation.
• Using aftermarket tire sealants may
cause the Tire Pressure Monitoring Sys-
tem (TPMS) sensor to become inoper-
able. After using an aftermarket tire
sealant it is recommended that you take
CAUTION!
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.
NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation 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
maintenance, and it is the driver’s respon-
sibility 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 Telltale Light.”
95

• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Premium System
The Tire Pressure Monitor 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 compo-
nents:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system
messages, which display in the instrument
cluster
• Tire Pressure Monitoring System Warning
LightTire Pressure Monitoring Low Pressure Warn-
ings
The “Tire Pressure Monitoring
Telltale Light” will illuminate in
the instrument cluster and a
chime will sound when tire pres-
sure is low in one or more of the
four active road tires. In addition, the instru-
ment cluster will display a "Tire Low" mes-
sage for a minimum of five seconds and a
graphic showing the pressure values of each
tire with the low tire pressure values in a
different color.
Should this occur, you should stop as soon as
possible and inflate the tires with low pres-
sure (those in a different color in the instru-
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure value. Once
the system receives the updated tire pres-
sures, the system will automatically update,
the pressure values in the graphic display in
the instrument cluster will return to their
original color, and the “Tire Pressure Monitor-
ing Telltale Light” will turn off. The vehicle

may need to be driven for up to 10 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 plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Telltale 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 TPM SYSTEM" mes-
sage for a minimum of five seconds and then
display dashes (- -) in place of the pressure
value to indicate which sensor is not being
received.
If the ignition key is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists, the
“Tire Pressure Monitoring Telltale Light” will
no longer flash, and the “SERVICE TPM SYS-
TEM” message will no longer display, and apressure value will display in place of the
dashes. A system fault can occur due to any
of the following:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
• Lots 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 or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching
full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the com-
pact 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 TelltaleLight” will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a dif-
ferent color pressure value.
3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the “TPMS
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will dis-
play 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 Telltale
Light” will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment cluster will display a “SERVICE TPM
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
Telltale Light” will turn off and the
97

graphic in the instrument cluster will dis-
play 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
10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this
information.
TPMS Deactivation — If Equipped
The 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 Moni-
toring (TPM) Sensors. Then, drive the vehicle
for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the "TPM Telltale Light"
will flash on and off for 75 seconds and thenremain on. The instrument cluster will dis-
play the “SERVICE TPM 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 TPM 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 TPM sensors. Then, drive
the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the
"TPM Telltale Light" will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TPM SYS-
TEM” message and then display pressure
values in place of the dashes. On the next
ignition cycle the "SERVICE TPM SYSTEM"
message will no longer be displayed as long
as no system fault exists.OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air
Bags
• Child Restraints
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.
Important Safety Precautions
Please pay close attention to the information

How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward 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 disen-
gage the Automatic Locking Mode and acti-
vate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced
if the switchable Automatic Locking Re-
tractor (ALR) feature or any other seat
belt function is not working properly
when checked according to the proce-
dures in the Service Manual.
WARNING!
• 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 har-
ness for restraining the child.
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 cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. 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
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever 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.
109

Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has mul-
tistage driver and front passenger air bags.
This system provides output appropriate to
the severity and type of collision as deter-
mined 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 immedi-
ately during an impact that requires air bag
deployment. A low energy output is used in
less severe collisions. A higher energy output
is used for more severe collisions.
This vehicle may be equipped with a driver
and/or front passenger seat belt buckle
switch that detects whether the driver or front
passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of
the Advanced Front Air Bags.
This vehicle may be equipped with driver
and/or front passenger seat track position
sensors that may adjust the inflation rate of
the Advanced Front Air Bags based upon seat
position.
WARNING!
• No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air
bag to inflate.
• Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cush-
ions are designed to open only when the
air bags are inflating.
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
air bags won’t deploy at all. Always wear
your seat belts even though you have air
bags.
Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional 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 indica-
tors 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.
SAFETY
112

WARNING!
dows where the SABIC and its deploy-
ment path are located should remain
free from any obstructions.
• In order for the SABICs to work as in-
tended, do not install any accessory
items in your vehicle which could alter
the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof
racks that require permanent attach-
ments (bolts or screws) for installation
on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the de-
ployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the ap-
propriate response to impact events. The sys-
tem is calibrated to deploy the Side Air Bags
on the impact side of the vehicle during
impacts that require Side Air Bag occupantprotection. In side impacts, the Side Air Bags
deploy independently; a left side impact de-
ploys the left Side Air Bags only and a right-
side impact deploys the right Side Air Bags
only. Vehicle damage by itself is not a good
indicator of whether or not Side Air Bags
should have deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at cer-
tain angles, or some side collisions that do
not impact the area of the passenger com-
partment. The Side Air Bags may deploy
during angled or offset frontal collisions
where the front air bags deploy.
Side Air Bags are a supplement to the seat
belt restraint system. Side Air Bags deploy in
less time than it takes to blink your eyes.
WARNING!
• Occupants, including children, who are
up against or very close to Side Air Bags
can be seriously injured or killed. Occu-
pants, including children, should never
lean on or sleep against the door, side
windows, or area where the side air bags
WARNING!
inflate, even if they are in an infant or
child restraint.
• Seat belts (and child restraints where
appropriate) are necessary for your pro-
tection in all collisions. They also help
keep you in position, away from an in-
flating Side Air Bag. To get the best
protection from the Side Air Bags, occu-
pants must wear their seat belts properly
and sit upright with their backs against
the seats. Children must be properly
restrained in a child restraint or booster
seat that is appropriate for the size of the
child.
WARNING!
• Side Air Bags need room to inflate. Do
not lean against the door or window. Sit
upright in the center of the seat.
• Being too close to the Side Air Bags
during deployment could cause you to
be severely injured or killed.
• Relying on the Side Air Bags alone could
lead to more severe injuries in a colli-
115

WARNING!
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.
Rollover Events (If Equipped With Rollover
Sensing)
Side Air Bags are designed to activate in
certain rollover events (if equipped with roll-
over sensing). The ORC determines whether
the deployment of the Side Air Bags in a
particular rollover event is appropriate, based
on the severity and type of collision. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing system
determines if a rollover event may be inprogress and whether deployment is appro-
priate. In the event the vehicle experiences a
rollover or near rollover event, and deploy-
ment of the Side Air Bags is appropriate, the
rollover sensing system will also deploy the
seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu-
pants through side windows in certain roll-
over or side impact events.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting wiring associated with electrical Air
Bag System Components listed below:
• 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
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
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 oc-
cupants 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.
