SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The Anti-Lock Brake System (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.

ABS is activated during braking when the system
detects one or more wheels begin 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 when
ABS activates:
The ABS motor noise (it may continue to run
for a short time after the stop)
The clicking sound of solenoid valves
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stop
These are all normal characteristics of ABS.
ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires.
Modification may result in degraded ABS
performance.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to inter-
ference caused by improperly installed or
high output radio transmitting 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.

Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake 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 “Anti-Lock Brake 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 “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the
brake system should be serviced as soon as
possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning Light”
does not come on when the ignition is placed in
the ON/RUN mode, have the light repaired as
soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This
system includes Electronic Brake Force
Distribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Electronic
Roll Mitigation (ERM). These systems work
together to enhance both vehicle stability and
control in various driving conditions.
Your vehicle may also be equipped with Ready
Alert Braking (RAB), and Rain Brake Support
(RBS).
Brake Assist System (BAS)
The Brake Assist System (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.
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.

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” button 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 ON. 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.
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
RBS 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 Electronic Brake Controller (EBC)
will prepare the brake system for a panic stop.
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.

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
Stability Control (ESC) system, 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 miti -
gate 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
20 mph (32 km/h), the system may provide the
maximum or partial braking to mitigate the potential forward collision. If the Forward Colli
-
sion 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.
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.
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.

1. The transmission must be in PARK.

2. Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
WARNING!
When exiting the vehicle, always make sure
the ignition is in OFF mode, remove the key
fob from the vehicle and lock the vehicle.
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
transmission gear selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition (of a
vehicle equipped with Keyless Enter-N-Go)
in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
Shift into or out of PARK or REVERSE only
after the vehicle has come to a complete
stop.
WARNING! (Continued)
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is

IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be
in PARK before the ignition can be turned to the
OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without placing
the transmission in PARK. This system also
locks the transmission in PARK whenever the
ignition is in the OFF mode.
NOTE:
The transmission is NOT locked in PARK when
the ignition is in the ACC mode (even though the
engine will be off). Ensure that the transmission
is in PARK, and the ignition is OFF (not in ACC
mode) before exiting the vehicle.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK SYSTEM
This vehicle is equipped with a Brake
Transmission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must be
running and the brake pedal must be pressed.
The brake pedal must also be pressed to shift from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds.
EIGHT-SPEED AUTOMATIC
T
RANSMISSION
WARNING!
Never use the PARK position as a substi -
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
to guard against vehicle movement and
possible injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting to
PARK, and verify that the transmission gear
position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is
completely stopped, and the PARK position
is properly indicated, before exiting the
vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, and turn the igni -
tion OFF. When the ignition is in the OFF
mode, the transmission is locked in PARK,
securing the vehicle against unwanted
movement.
When exiting the vehicle, always make sure
the ignition is in the OFF mode, remove the
key fob from the vehicle, and lock the
vehicle.
