ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
If applicable, refer to the “Hybrid Supplement” for
additional information.
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 Hill Descent
Control (HDC), Rain Brake Support (RBS), Ready Alert
Braking (RAB), and Trailer Sway Control (TSC).
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.
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.
Electronic Brake Force Distribution (EBD)
EBD 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)
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.
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!
The Brake Assist System (BAS) cannot prevent the natu -
ral laws of physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing road condi -
tions. 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.

248SAFETY
Each time the ignition is place in the ON position, the
ESC system will be on even if it was turned off previ -
ously.
 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 Descent Control (HDC) — If Equipped
HDC is intended for low speed off-road driving while in
4WD Low. HDC maintains vehicle speed while descending
hills during various driving situations. HDC controls vehicle
speed by actively controlling the brakes.
HDC has three states:

1. Off (feature is not enabled and will not activate).

2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
 The driveline is in 4WD Low.
 The vehicle speed is below 5 mph (8 km/h).
 The parking brake is released.
 The driver door is closed. (If doors are attached, then
door must be closed. If doors are detached, then driver
seat belt must be buckled.) Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by
using the gear shift +/-. The following summarizes the
HDC set speeds:
HDC Target Set Speeds

P = No set speed. HDC may be enabled but will not acti -
vate
 R = 0.6 mph (1 km/h)
 N = 1.2 mph (2 km/h)
 D = 0.6 mph (1 km/h)
 1st = 0.6 mph (1 km/h)
 2nd = 1.2 mph (2 km/h)
 3rd = 1.8 mph (3 km/h)
 4th = 2.5 mph (4 km/h)
 5th = 3.1 mph (5 km/h)
 6th = 3.7 mph (6 km/h)
 7th = 4.3 mph (7 km/h)
 8th = 5.0 mph (8 km/h)
 9th = 5.6 mph (9 km/h) – If Equipped
NOTE:During HDC the +/- shifter input is used for HDC target
speed selection, but will not affect the gear chosen by the
transmission. When actively controlling HDC the trans -
mission will shift appropriately for the driver-selected set
speed and corresponding driving conditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at any time. Deactivating HDC
HDC will be deactivated but remain available if any of the
following conditions occur:

Driver overrides HDC set speed with throttle or brake
application.
 Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h).
 Vehicle is on a downhill grade of insufficient magni-
tude, is on level ground, or is on an uphill grade.
 Vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
 The driver pushes the HDC switch.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens. (Driver door opens if doors are
attached or driver seat belt is unbuckled if doors are
detached.)
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(HDC exits immediately).
 HDC detects excessive brake temperature.

250SAFETY
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 Controller (EBC) will prepare the brake
system for a panic stop.
Selec-Speed Control (SSC) — If Equipped
SSC is intended for off-road driving in 4WD Low
only. SSC maintains vehicle speed by actively
controlling engine torque and brakes.
SSC has three states:

1. Off (feature is not enabled and will not activate)

2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is actively overriding
with brake or throttle application)
3. Active (feature is enabled and actively controlling vehicle speed)
Enabling SSC
SSC is enabled by pushing the SSC switch, but the
following conditions must also be met to enable SSC:
 The driveline is in 4WD Low.
 The vehicle speed is below 5 mph (8 km/h).
 The parking brake is released.
 The driver door is closed (If doors are attached, the
door must be closed. If doors are detached, the driver
seat belt must be buckled).
 The driver is not applying throttle. Activating SSC
Once SSC is enabled it will activate automatically once the
following conditions are met:

The driver releases the throttle.
 The driver releases the brake.
 The driver seat belt is buckled.
 The transmission is in any selection other than PARK.
 Your vehicle speed is below 20 mph (32 km/h).
 The driver door is closed. (If doors are attached, the
door must be closed. If doors are detached, the driver
seat belt must be buckled).
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade and
the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
 1st = 0.6 mph (1 km/h)
 2nd = 1.2 mph (2 km/h)
 3rd = 1.8 mph (3 km/h)
 4th = 2.5 mph (4 km/h)
 5th = 3.1 mph (5 km/h)
 6th = 3.7 mph (6 km/h)
 7th = 4.3 mph (7 km/h)
 8th = 5 mph (8 km/h)
 9th = 5.6 mph (9 km/h) — if equipped
 REVERSE = 0.6 mph (1 km/h)
 NEUTRAL = 1.2 mph (2 km/h)
 PARK = SSC remains enabled but not active SSC Target Set Speeds — If Equipped With Off Road+

1st = 0.6 mph (1 km/h)
 2nd = 0.9 mph (1.5 km/h)
 3rd = 1.2 mph (2 km/h)
 4th = 1.5 mph (2.5 km/h)
 5th = 1.8 mph (3 km/h)
 6th = 2.5 mph (4 km/h)
 7th = 3.7 mph (6 km/h)
 8th = 5 mph (8 km/h)
 REVERSE = 0.6 mph (1 km/h)
 NEUTRAL = 1.2 mph (2 km/h)
 PARK = SSC remains enabled but not active
NOTE:
During SSC, the +/- gear selector input is used for SSC
target speed selection but will not affect the gear
chosen by the transmission. While actively controlling
SSC, the transmission will shift appropriately for the
driver-selected set speed and corresponding driving
conditions.
 SSC operation is influenced by Off Road+ drive mode if
active. The differences may be notable to the driver as
a varying level of aggressiveness.
Driver Override
The driver may override SSC activation with throttle or
brake application at any time.

260SAFETY
The system will be activated when the system detects an
increase in tire pressure while filling the tire. The ignition
must be in the ON/RUN mode with the transmission in
PARK for vehicles equipped with an automatic
transmission. For vehicles equipped with a manual
transmission, the parking brake must be applied.
NOTE:It is not required to have the engine running to enter Tire
Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode. If the hazard lamps do not come on
while inflating the tire, the Tire Pressure Monitoring
System sensor may be in an inoperative position,
preventing the TPMS sensor signal from being received. In
this case, the vehicle may need to be moved slightly
forward or backward.
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
The horn will chirp once to let the user know when to
stop filling the tire, when it reaches recommended
pressure.
 The horn will chirp three times if the tire is overfilled
and will continue to chirp every five seconds if the user
continues to inflate the tire.
 The horn will chirp once again when enough air is let
out to reach proper inflation level.
 The horn will also chirp three times if the tire is then
underinflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
NOTE:The Tire Fill Alert feature is set to “Disabled” every time the
ignition is turned to “OFF”. To re-enable the Tire Fill Alert
feature at the next ignition “RUN” state, the customer
must re-enable the feature through use of the customer
settings in the radio.
SELECTABLE TIRE FILL ALERT (STFA) —
IF EQUIPPED
The STFA system is an optional feature that is included as
part of the normal Tire Fill Alert system. The system is
designed to allow you to select a pressure to inflate or
deflate the vehicle's front and rear axle tires to, and to
provide feedback while inflating or deflating the vehicle's
tires.
NOTE:To use the STFA feature, the Tire Fill Alert feature must be
enabled through use of the customer settings in the radio.
In the Selectable Tire Fill Alert application, which is located
in the apps menu of the Uconnect system, you will be able
to select a pressure setting for both the front and rear axle
tire pressures by scrolling through a pressure range from
XX to 15 psi in 1 psi increments for each axle setting.
XX = the vehicle's cold placard pressure values for the
front and rear axles as shown on the vehicle placard
pressure label.
You may also store pressure values chosen for each axle
in the Uconnect system application as preset pressure
values. Up to two sets of preset pressure values can be
stored in the Uconnect system for the front and rear axle. Once you select the tire pressures for the front and rear
axles that you want to inflate or deflate to, you can begin
inflating or deflating one tire at a time.
NOTE:The STFA system will only support inflating or deflating one
tire at a time.
The system will be activated when the TPMS receiver
module detects a change in tire pressure. The ignition
must be in the ON/RUN mode, with the transmission in
PARK in vehicles with an automatic transmission, and in
NEUTRAL with the parking brake engaged in vehicles with
a manual transmission. The hazard lamps will come on to
confirm the vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire pressure
screen will be displayed in the instrument cluster. If the
hazard lamps do not come on while inflating or deflating
the tire, the Tire Pressure Monitoring System sensor may
be in an inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle may
need to be moved slightly forward or backward.
Horn chirps will indicate STFA status as tires are inflated/
deflated. The horn will chirp under the following STFA
states:

1. The horn will chirp once when the selected pressure
is reached to let you know when to stop inflating or
deflating the tire.

2. The horn will chirp three times if the tire is overin -
flated or over-deflated.
3. The horn will chirp once again when enough air is added or removed to reach proper selected pressure
level.

276SAFETY
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 occupants 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. However, if you haven’t healed signifi -
cantly within a few days, or if you have any blistering,
see your doctor immediately.
 As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate the
skin, eyes, nose, or throat. If you have skin or eye irrita -
tion, rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc -
tions for cleaning.
Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will not
be in place to protect you.NOTE:
 Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
 After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the Occupant Restraint
Controller (ORC) will determine whether to have the
Enhanced Accident Response System perform the
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 inter -
vention 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 Circulation 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
NOTE:After an accident, remember to cycle the ignition to the
START or ON/OFF 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 elec -
trical 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
If applicable, refer to the “Hybrid Supplement” for
additional information.
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
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.
After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must be
towed to an authorized dealer to be inspected and to have
the Enhanced Accident Response System reset.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant Restraint
Controller System serviced as well.
