SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to en-
sure 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.
WARNING!
• The ABS contains sophisticated elec-
tronic equipment that may be suscep-
tible to interference caused by improp-
erly installed or high output radio
transmitting equipment. This interfer-
ence 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
WARNING!
condition of the vehicle brakes and tires
or the traction afforded.
• The ABS cannot prevent collisions, in-
cluding 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.
ABS is designed to function with the OEM
tires. Modification may result in degraded
ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light”
will turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long as
four seconds.
If the “Anti-Lock Brake Warning Light” re-
mains on or comes on while driving, it indi-
cates that the anti-lock portion of the brake
system is not functioning and that service is
SAFETY

required. However, the conventional brake
system will continue to operate normally if
the “Brake System Warning Light” is not 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
turned to the ON/RUN mode, have the light
repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force Dis-
tribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Elec-
tronic Roll Mitigation (ERM). These systems
work together to enhance both vehicle stabil-
ity and control in various driving conditions.
Your vehicle may also be equipped with
Ready Alert Braking (RAB), Rain Brake Sup-
port (RBS), Trailer Sway Control (TSC), and
Dynamic Steering Torque (DST).
Traction Control System (TCS)
This system 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 re-
duce vehicle power to provide enhanced ac-
celeration and stability. A feature of the TCS,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols 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 ESC are in a reduced
mode.
Brake Assist System (BAS) — If Equipped
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emer-
gency 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 re-
sults in the best BAS assistance. To receive
the benefit of the system, you must apply
continuous braking pressure during the stop-
ping 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.
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 man-
ner, 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 igni-
tion is turned ON.
• Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.
• The ESC system will make buzzing or click-
ing 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 re-
duced mode.Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driv-
ing while in 4WD Low Range. HDC maintains
vehicle speed while descending hills during
various driving situations. HDC controls ve-
hicle 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:
• Driveline is in 4WD Low Range.
• Vehicle speed is below 7.5 mph (12 km/h).
• Electric Park Brake (EPB) is released.
• Driver’s door is closed.
Hill Descent Control (Trailhawk)
SAFETY
82

The following conditions must be met in
order for HSA to activate:
• The feature must be enabled.
• The vehicle must be stopped.
• Park brake must be off.
• Driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle up-
hill direction (i.e., vehicle facing uphill is in
forward gear; vehicle backing uphill is in
REVERSE gear).
• HSA will work in REVERSE gear and all
forward gears. The system will not activate
if the transmission is in PARK or NEU-
TRAL. 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 op-
eration 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 warn-
ings can result in a collision or serious
personal injury.
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 pressure to hold both the vehicle
and the trailer on a hill when the brake
WARNING!
pedal is released. In order to avoid roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure 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 re-
sult in a collision or serious personal
injury.
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 Uconnect Settings,
refer to “Uconnect Settings” in “Multime-
dia” for further information.

Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency 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)
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 recog-
nized.NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further 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” or “Full
Off” modes.
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.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, to detect highway
licensable vehicles (automobiles, trucks, mo-
torcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle.
Rear Detection Zones

Forward Collision Warning (FCW) With
Mitigation — If Equipped
Forward Collision Warning (FCW) With Miti-
gation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with au-
dible 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 for-
ward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the prob-
ability of a forward collision. When the sys-
tem 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 tohelp slow the vehicle and mitigate the poten-
tial forward collision. If the driver reacts to
the warnings by braking and the system de-
termines that the driver intends to avoid the
collision by braking but has not applied suf-
ficient brake force, the system will compen-
sate 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 maxi-
mum braking possible to mitigate the poten-
tial forward collision. If the Forward Collision
Warning with Mitigation event stops the ve-
hicle completely, the system will hold the
vehicle at standstill for two seconds and then
release the brakes.
When the system determines a collision with
the vehicle in front of you is no longer prob-
able, the warning message will be deacti-
vated.
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 a key
cycle, the Active Braking portion of FCW
will be deactivated until the next key 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 pre-
vent 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 ve-
hicle via braking and steering. Failure to
follow this warning could lead to serious
injury or death.

STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.
WARNING!
• When exiting the vehicle, always remove
the key fob from the vehicle and lock
your vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously 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
children, 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.
WARNING!
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
Start the engine with the gear selector in the
NEUTRAL or PARK position. Apply the brake
before shifting to any driving range.
Normal Starting — Gasoline Engine
