Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, or striking
objects or other vehicles.
Electronic Stability Control (ESC)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to counteract the above conditions.
Engine power may also be reduced to help the
vehicle maintain the desired path.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC
applies the brake of the appropriate wheel to
assist in counteracting the oversteer or understeer
condition. The ESC Activation/Malfunction Indicator Light
located in the instrument cluster will start to flash
as soon as the ESC system becomes active. The
ESC Activation/Malfunction Indicator Light also
flashes when the TCS is active. If the ESC
Activation/Malfunction Indicator Light begins to
flash during acceleration, ease up on the
accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the
prevailing road conditions.
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence
the chance that wheel lift or rollover may occur.
ERM cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
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 condi
-
tions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydro -
planing. 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.

ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC.
Whenever the vehicle is started, the ESC system
will be in this mode. This mode should be used for
most driving conditions. Alternate ESC modes
should only be used for specific reasons as noted
in the following paragraphs.Partial Off
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button, located below the radio. The
ESC OFF Indicator Light will illuminate. To turn the
ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:
When driving with snow chains, or when starting off
in deep snow, sand, or gravel, it may be desirable to
allow more wheel spin. This can be accomplished by
momentarily pushing the ESC OFF button to enter
“Partial Off” mode. Once the situation requiring
“Partial Off” mode is overcome, turn ESC back on by
momentarily pushing the ESC OFF button. This may
be done while the vehicle is in motion.

Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-road
use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions.
This mode is entered by pushing and holding the
ESC OFF button for five seconds when the vehicle
is stopped and the engine is running. After five
seconds, the ESC OFF Indicator Light will illuminate
and the “ESC OFF” message will appear in the
instrument cluster display.
In this mode, ESC and TCS, except for the “limited
slip” feature described in the TCS section, are
turned off until the vehicle reaches a speed of
40 mph (64 km/h). At 40 mph (64 km/h), the
system returns to “Partial Off” mode, as described
above. TCS remains off. When the vehicle speed
drops below 30 mph (48 km/h), the ESC system
shuts off. ESC is deactivated at low vehicle speeds
so that it will not interfere with off-road driving.
However, ESC function returns to provide the
stability feature at speeds above 40 mph
(64 km/h). The ESC OFF Indicator Light will always
be illuminated when ESC is off.
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 perfor
-
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
WARNING!
When in “Partial Off” mode, the TCS function -
ality of ESC, except for the limited slip feature
described in the TCS section, has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.
WARNING!

SAFETY195
The BSM detection zone covers approximately
one lane width, 12 ft (3.8 m), on both sides of the
vehicle. The zone length starts at the outside
mirror and extends approximately 10 ft (3 m)
beyond the rear fascia/bumper of the vehicle. The
BSM system monitors the detection zones on both
sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher
and will alert the driver of vehicles in these areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system will automatically disable when
a trailer is detected. If the attached trailer is not
detected, the system detection zone DOES NOT
change. Therefore, visually verify the adjacent
lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or
other object (i.e., bicycle, sports equipment)
extends beyond the side of your vehicle, this
may result in the BSM warning light remaining
illuminated the entire time the vehicle is in a
forward gear. It may be necessary to deactivate
the BSM system manually to avoid misdetection
Ú page 165.
The BSM system can become blocked if snow, ice,
mud, or other road contaminations accumulate on
the rear fascia/bumper where the radar sensors
are located. The system may also detect blockage if the vehicle is operated in areas with extremely
low radar returns such as a desert or parallel to a
large elevation drop. If blockage is detected, a
“Blind Spot Temporarily Unavailable, Sensor
Blocked” message will display in the cluster, both
mirror lights will illuminate, and BSM and RCP
alerts will not occur. This is normal operation. The
system will automatically recover and resume
function when the condition clears or when an
ignition cycle occurs. To minimize system
blockage, do not block the area of the rear fascia/
bumper where the radar sensors are located with
foreign objects (bumper stickers, bicycle racks,
etc.) and keep it clear of road contaminations.

Radar Sensor Location (Driver Side Shown)

The BSM system will provide a visual alert in the
appropriate side view mirror based on a detected
object when enabled. 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 chimes are enabled. In addition
to the audible alert the radio (if on) will also be
muted during the chime event Ú
page 198.

Warning Light Location

As part of the Active Lane Management system, if
the vehicle begins to drift into an adjacent lane
that has an active LED indication, the LED will flash
if steering torque is provided to guide the vehicle
back to the center of the lane Ú page 145.
The BSM system monitors the detection zone from
three different entry points (side, rear, front) while
driving to see if an alert is necessary. The BSM
system will issue an alert during these types of
zone entries.

SAFETY199
If a Forward Collision Warning with Mitigation event
begins at a speed below 39 mph (62 km/h), the
system may provide the maximum braking
possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will
hold the vehicle at standstill for two seconds and
then release the brakes.

FCW Message

When the system determines a collision with the
vehicle in front of you is no longer probable, the
warning message will be deactivated Úpage 328.
NOTE:
The minimum speed for FCW activation is
1 mph (2 km/h).
The FCW alerts may be triggered on objects
other than vehicles such as guardrails or sign
posts based on the course prediction. This is
expected and is a part of normal FCW activation
and functionality.
It is unsafe to test the FCW system. To prevent
such misuse of the system, after four Active
Braking events within a key cycle, the Active
Braking portion of FCW will be deactivated until
the next key cycle.
The FCW system is intended for on-road use
only. If the vehicle is taken off-road, the FCW
system should be deactivated to prevent unnec -
essary warnings to the surroundings.
FCW Settings
The Forward Collision menu setting is located in
the Uconnect Settings Ú page 165.
NOTE:The default status of FCW is “Full On,” this allows
the system to provide warning and autonomous
braking in the event of a potential frontal collision.
Changing the FCW status to “Only Warning”
prevents the system from providing autonomous
braking, or additional brake support if the driver is
not braking adequately in the event of a potential
frontal collision.
Changing the FCW status to “Off” deactivates the
system, so no warning or autonomous braking will
be available in case of a possible collision.
NOTE:The FCW system state is kept in memory from one
ignition cycle to the next. If the system is turned off,
it will remain off when the vehicle is restarted.
Changing FCW Sensitivity And Operating
Status
The FCW Sensitivity and Operation settings are
programmable through the Uconnect system
Úpage 165.
The default status of FCW is the “Medium” setting
and the FCW is in the “Full On” setting. This allows
the system to warn the driver of a possible collision
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.

Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the Controls settings Ú page 165.
To turn the PEB system off, push the Pedestrian
Emergency Braking OFF button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected
by the driver after ignition shut down. The system
will not reset to the default setting when the
vehicle is restarted.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure
based on the vehicle recommended cold placard
pressure.
The 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 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.
For more information on how to properly inflate the
vehicle’s tires, see Ú page 298.
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.
NOTE:
Once the low tire pressure warning (Tire Pressure
Monitoring System Warning Light) illuminates, you
must increase the tire pressure to the recommended
cold placard pressure in order for the Tire Pressure
Monitoring System Warning Light to turn off.

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.
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
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. 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.

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 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
Occupant Classification System
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,
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 igni
-
tion 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 intermit -
tently or remains on while driving.
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.

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 Ú
page 89.
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 Bag/Knee 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.
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.

2 — Driver Knee Impact Bolster/Supplemental
Driver Knee Air Bag
3 — Passenger Knee Impact Bolster
WARNING!
Being too close to the steering wheel or instru -
ment panel during front air bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfort -
ably 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.

SAFETY215
(Continued)
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.
This vehicle is equipped with a right front
passenger Occupant Classification System (OCS)
that is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s
seated weight input, as determined by the OCS.
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.
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 collisions, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.
