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)
Dynamic Steering Torque (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 Electronic Brake Force Distribution (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 ABS before
the front axle.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel
lift by monitoring the driver’s steering wheel
input and the speed of the vehicle. When
Electronic Roll Mitigation (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)
This system enhances directional control and
stability of the vehicle under various driving
conditions. Electronic Stability Control (ESC)
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to assist in counteracting the oversteer
or understeer condition. Engine power may also
be reduced to help the vehicle maintain the
desired path. 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.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel posi
-
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi -
tion.
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 Traction
Control System (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 roll
overs, 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 conditions. Only a safe, atten -
tive, and skillful driver can prevent acci -
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck -
less or dangerous manner which could
jeopardize the user’s safety or the safety of
others.

NOTE:
The “ESC Activation/Malfunction Indicator
Light” and the “ESC OFF Indicator Light”
come on momentarily each time the ignition
is turned to the ON/RUN mode.
Each time the ignition is turned to ON/RUN
mode, 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.
The “ESC OFF Indicator Light”
indicates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) system 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). For vehicles equipped with a manual
transmission, if the clutch is pressed, HSA
will remain active.
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.

SAFETY129
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using your instrument cluster
display, refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
for further information.
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multimedia”
for further information.
For vehicles not equipped with an instrument
cluster display, perform the following steps:

1. Center the steering wheel (front wheels pointing straight forward).

2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left. 6. Push the “ESC OFF” switch located in the
lower switch bank below the climate control
four times within 20 seconds. The “ESC Off
Indicator Light” should turn on and turn off
two times.
7. Rotate the steering wheel back to center and then an additional slightly more than
one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to the ON/RUN mode. If the sequence
was completed properly, the “ESC OFF
Indicator Light” will blink several times to
confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Towing With HSA
HSA will also provide assistance to Mitigate roll
back while towing a trailer.
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 pres -
sure 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 acti -
vate 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 trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.

Traction Control System (TCS)
The Traction Control System (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 engine power to provide
enhanced acceleration and stability. A feature
of the TCS, Brake Limited Differential (BLD),
functions similar 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
engine power to be applied to the wheel that is
not spinning. BLD may remain enabled even if
TCS and ESC are in reduced modes.
Rain Brake Support (RBS)
Rain Brake Support (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 Rain Brake Support is active, there is no
notification to the driver and no driver
interaction is required.
Ready Alert Braking (RAB)
Ready Alert Braking (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 EBC will prepare the brake
system for a panic stop.
Trailer Sway Control (TSC)
Trailer Sway Control (TSC) uses sensors in the
vehicle to recognize an excessively swaying
trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become
active automatically once an excessively
swaying trailer is recognized. Note that TSC
cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations.
Refer to “Trailer Towing” in “Starting And
Operating” for more information. 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.
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.

FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
The Forward Collision Warning (FCW) with
Mitigation system 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 warn-
ings 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 Forward Collision Warning with Mitigation
event begins at a speed below 26 mph
(42 km/h), the system may provide the
maximum or partial braking 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 a 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.
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 guard rails 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 an ignition cycle,
the Active Braking portion of FCW will be
deactivated until the next ignition 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
unnecessary warnings to the surroundings. If
the vehicle enters 4L range, the FCW system
will be automatically deactivated.

20_WD_OM_EN_USC_t.book Page 136

SAFETY137
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status
are programmable through the Uconnect
System. Refer to “Uconnect Settings” in
“Multimedia” for further information.
The default sensitivity of FCW is the “Medium”
setting and the system status is “Warning &
Braking”. This allows the system to warn the
driver of a possible collision with the vehicle in
front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to the “Far” setting
allows the system to warn the driver of a
possible collision with the vehicle in front using
audible/visual warning when the latter is at a
farther distance than the “Medium” setting. This provides the most reaction time to avoid a
possible collision.
Changing the FCW status to the “Near” setting,
allows the system to warn the driver of a
possible collision with the vehicle in front when
the distance between the vehicle in the front is
much closer. This setting provides less reaction
time than the “Far” and “Medium” settings,
which allows for a more dynamic driving
experience.
NOTE:
Changing the FCW status to “Only Warning”
prevents the system from providing limited
active braking, or additional brake support if
the driver is not braking adequately in the
event of a potential frontal collision, but
maintains the audible and visual warnings.
Changing the FCW status to “Off” 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.
The system will retain the last setting
selected by the driver after ignition shut
down.
FCW may not react to irrelevant objects such
as overhead objects, ground reflections,
objects not in the path of the vehicle,
stationary objects that are far away,
oncoming traffic, or leading vehicles with the
same or higher rate of speed.
FCW will be disabled like ACC, with the
unavailable screens.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is
still drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance
is no longer present, the system will return to its
full performance state. If the problem persists,
see an authorized dealer.
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.

following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on
as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform
any of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circula -
tion Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump
NOTE:
After an accident, remember to cycle the igni -
tion to the STOP (OFF/LOCK) position and
remove the key from the ignition switch to avoid
draining the battery. Carefully check the vehicle
for fuel leaks in the engine compartment and on
the ground near the engine compartment and
fuel tank before resetting the system and
starting the engine. If there are no fuel leaks or
damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system
by following the procedure described below. If you have any doubt, contact an authorized
dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident
