SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
If applicable, refer to the “Hybrid Supplement” for
additional information.
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically prevents wheel lock and enhances vehicle
control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.
The ABS is activated during braking when the system
detects one or more wheels are beginning to lock. Road
conditions such as ice, snow, gravel, bumps, railroad
tracks, loose debris, or panic stops may increase the
likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may continue
to hear for a short time after the stop)
 Brake pedal pulsations
 A slight drop of the brake pedal at the end of the stop The ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification may
result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the ignition
is placed in the ON/RUN mode and may stay on for as long
as four seconds.
If the ABS Warning Light remains on or comes on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock Brakes. If the ABS Warning Light does not come
on when the ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
WARNING!

The ABS contains sophisticated electronic equip -
ment that may be susceptible to interference caused
by improperly installed or high output radio transmit -
ting equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
 Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
 The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or the
traction afforded.
 The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user’s safety or the
safety of others.

ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control (EBC) system. This system includes
Anti-Lock Brake System (ABS), Brake Assist System (BAS),
Electronic Brake Force Distribution (EBD), Electronic Roll
Mitigation (ERM), Electronic Stability Control (ESC), Hill
Start Assist (HSA), and Traction Control System
(TCS).These systems work together to enhance both
vehicle stability and control in various driving conditions.
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Ready Alert Braking (RAB), Rain Brake
Support (RBS) and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the ESC and Electric Power Steering
(EPS) modules that provides torque at the steering wheel
for certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain vehicle stability. The only notification the driver receives
that the feature is active, is the torque applied to the
steering wheel.
NOTE:The DST feature is only meant to help the driver realize the
correct course of action through small torques on the
steering wheel, which means the effectiveness of the DST
feature is highly dependent on the driver’s sensitivity and
overall reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering the
vehicle.
Electronic Brake Force Distribution (EBD)
The EBD function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip
of the rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering the Anti-Lock Brake
System (ABS) before the front axle.
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, striking objects or other vehicles.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The
capabilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user's safety or the safety of
others.

23_RUP_OM_EN_USC_t.book Page 188

SAFETY189
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 assist in
counteracting these 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.
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 and 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 momen
-
tarily pushing the ESC OFF button to enter partial mode
“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.
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
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. 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.

 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is placed in the ON/RUN mode. It
should go out with the engine running. If the
ESC Activation/Malfunction Indicator Light comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as possible to have the problem diagnosed and corrected. The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction Indicator
Light also flashes when 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.
The ESC OFF Indicator Light indicates that the
Electronic Stability Control (ESC) is in a reduced
mode.
NOTE:
The ESC Activation/Malfunction Indicator Light and the
ESC OFF Indicator Light come on momentarily each
time the ignition is placed in the ON/RUN position.
 Each time the ignition is placed in the ON/RUN posi -
tion, the ESC system will be on even if it was turned off
previously.
 The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete stop
while on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not apply the
throttle before this time expires, the system will release
brake pressure and the vehicle will roll down the hill as
normal. The following conditions must be met in order for HSA to
activate:

The feature must be enabled.
 The vehicle must be stopped.
 The parking brake must be off.
 The driver door must be closed.
 The vehicle must be on a sufficient grade.
 The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE (R) gear).
 HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK (P) or NEUTRAL (N).
WARNING!
When in “Partial Off” mode, the TCS functionality 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!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active driving
involvement. It is always the driver’s responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.

(Continued)
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows: Úpage 157.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet conditions.
It will periodically apply a small amount of brake pressure
to remove any water buildup on the front brake rotors. It
functions when the windshield wipers are in LO or HI
speed. When RBS is active, there is no notification to the
driver and no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates when
an emergency braking situation may occur by monitoring
how fast the throttle is released by the driver. The
Electronic Brake Control (EBC) system will prepare the
brake system for a panic stop.
Rear Seat Reminder Alert (RSRA)
RSRA alerts you through a visual and auditory notification
of the possible presence of an object, passenger, or pet in
the rear seats if a rear door was opened up to 10 minutes
before the ignition was placed in the ON/RUN position.
RSRA does not directly detect objects, passengers, or pets
in the rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on the
instrument cluster display and sounds an auditory alert
upon the driver placing the ignition in the OFF position to
exit the vehicle.
To enable or disable RSRA, see
Úpage 157.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
vehicle power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more vehicle torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
the Electronic Stability Control (ESC) are in reduced
modes.
WARNING!
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
the brake pedal.
 HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
 Failure to follow these warnings can result in a colli -
sion or serious personal injury.
WARNING!
 Before exiting a vehicle, always come to a complete
stop, then shift the automatic transmission into
PARK and apply the parking brake.
 Always make sure the keyless ignition node is in the
OFF position, key fob is removed from the vehicle
and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector.
 Do not leave children or animals inside parked vehi -
cles in hot weather. Interior heat buildup may cause
serious injury or death.
WARNING!

Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway. Note that TSC cannot
stop all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations
Úpage 147.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
The BSM system uses two radar sensors, located inside
the rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.) that
enter the blind spot zones from the rear/front/side of the
vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear and enters standby mode when the vehicle is
in PARK (P).
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.7 m). The zone
length starts at the outside rearview 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 detection zone DOES NOT change if
your vehicle is towing a trailer. 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 false
detections. The BSM Warning Light may even remain
illuminated the entire time the vehicle is in a forward
gear.
 The Blind Spot Monitoring (BSM) system may experi -
ence dropouts (blinking on and off) of the side mirror
warning indicator lights when a motorcycle or any small
object remains at the side of the vehicle for extended
periods of time (more than a couple of seconds).
The area on the rear fascia/bumper where the radar
sensors are located must remain free of snow, ice, and
dirt/road contamination so that the BSM system can
function properly. Do not block the area of the rear fascia/
bumper where the radar sensors are located with foreign
objects (bumper stickers, bicycle racks, etc.).

Sensor Location

WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

23_RUP_OM_EN_USC_t.book Page 192

SAFETY195
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 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 operating mode
when the vehicle is shut off. Each time the vehicle is
started the previously stored mode will be recalled and
used.
 The BSM system can work in conjunction with the
KeySense function of the vehicle (if equipped)
Úpage 98.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with audible
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 forward looking
sensors as well as the Electronic Brake Controller (EBC), 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
and may provide a brake jerk warning.
If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver reacts
to the warnings by braking and the system determines
that the driver intends to avoid the collision by braking but
has not applied sufficient brake force, the system will
compensate and provide additional brake force as
required.
If a FCW with Mitigation event begins at a speed below
37 mph (60 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. If a pedestrian is encountered in the path at
the same speed threshold, the system will attempt to
bring the vehicle to a stop.

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 312.
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.
