SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
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.
REAR SEAT REMINDER ALERT (RSRA) —
I
F EQUIPPED
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.
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
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.

246SAFETY
(Continued)
NOTE:ERM is disabled any time the ESC is in “Full Off” mode (if
equipped) Úpage 246.
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 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
“ESC On” 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.
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 capa-
bilities 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 oth
-
ers.
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 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 capabil -
ities 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.

SAFETY251
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
The driver overrides SSC set speed with throttle or
brake application.
The vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h).
The vehicle is shifted into PARK.
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
The driver pushes the SSC switch.
The driveline is shifted out of the 4WD Low.
The parking brake is applied.
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).
SSC will exist immediately.
The driver door opens. (Driver door opens if doors are
attached or driver seat belt is unbuckled if doors are
detached).
Feedback To The Driver
The instrument cluster has an SSC icon and the SSC
switch has a lamp that offers feedback to the driver about
the state SSC is in.
The cluster icon and switch lamp will illuminate and
remain on solid when SSC is enabled or activated.
These are the normal operating conditions for SSC.
The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enabled conditions are not met.
The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
The cluster icon and switch lamp will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
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 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 engine torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in reduced modes.
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:TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations
Úpage 170.
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” or
“Full Off” modes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off-road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
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.6
