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. Place the ignition in 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.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
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.
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 pedal is released. In order to
avoid rolling down an incline while resuming
acceleration, manually activate 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.

NOTE:
When a trailer with an electric brake is
connected to the vehicle, the instrument cluster
display will provide a menu to allow a selection
of the trailer type. There will be two options
provided: Conventional and Goose/Fifth Wheel.
Goose/Fifth Wheel Trailer is incompatible and
when selected, the BSM system will disable
until the trailer is disconnected. If the wrong
option is selected, the system can be reset by
either disconnecting and reconnecting the
trailer harness connector or disabling then
re-enabling the Blind Spot Monitoring System in
the customer settings in the Uconnect. This will
prompt the trailer selection menu again to allow
for the correct selection.
Trailer Merge Assist is a function of the Blind
Spot Monitoring (BSM) system that extends the
blind spot zone to work while pulling a trailer.
Trailer Merge Assist consists of three sub
functions:
Automatic Trailer Detection
Trailer Length Detection
Trailer Merge Warning
Blind Spot Zones With Trailer Merge Assist

Automatic Trailer Detection
There are two modes of operation for the
detection of the trailer length:
Automatic Mode — When “Auto Mode” is
selected, the system will use the blind spot
sensors to automatically determine the pres -
ence and length of a trailer. The presence of
a trailer will be detected using the blind spot
radar within 90 seconds of forward move -
ment of the vehicle. The vehicle must be
moving above 6 mph (10 km/h) to activate the feature. Once the trailer has been
detected, the system will default to the maximum blind spot zone until the length has
been verified. You will see “Auto” in the
instrument panel cluster .
Max Mode
— When “Max Mode” is selected,
the system will default to the maximum blind
spot zone regardless of what size trailer is
attached .
NOTE:
Selected setting is stored when the ignition is
placed in the OFF position. To change this
setting, it must be selected through the Ucon -
nect Settings. Refer to “Uconnect Settings” in
“Multimedia” for further information.
Trailer Length Detection
Once the trailer presence has been established,
the trailer length will be established (by making
a 90 degree turn) and then the trailer length
category (e.g. 10-20 ft (3 m to 6 m)) will be
displayed. This can take up to 30 seconds after
completing the turn.
NOTE:
During the same ignition cycle, if the vehicle is
at a standstill for a minimum of 90 seconds, a
new “trailer detection request” is enabled by
the system once the vehicle resumes motion.

FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
The Forward Collision Warning (FCW) system
provides the driver with audible, visual warnings
(within the instrument cluster display), and may
apply a haptic warning in the form of a brake
jerk, to warn the driver when it detects a
potential frontal collision. The warnings 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 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 as well as a possible haptic warning in the
form of a brake jerk.
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 warn -
ings by braking and the system determines that
the driver intends to avoid the collision by
WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.

If the hazard lamps do not come on while inflating
the tire, the TPM sensor may be in a inoperative
position, preventing the TPM 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
over filled 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 under-inflated and will continue to
chirp every five seconds if the user continues
to deflate the tire. Selectable Tire Fill Alert (STFA)
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow the customer to select a
pressure to inflate or deflate the vehicle's front
and rear axle tires to and to provide feedback to
the customer while inflating or deflating the
vehicle's tires.
In the Selectable Tire Fill Alert application,
which is located in the apps menu of the
Uconnect System, the customer 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.
The customer may also store the pressure
values chosen for each axle in the radio as a
preset pressure. The customer will be allowed
to store up to two sets of preset values in the
radio for the front and rear axle pressure values. Once the customer selects the tire pressures for
the front and rear axles that they want to inflate
or deflate to, they 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 TPM
receiver module detects a change in tire
pressure. The ignition must be in the RUN
mode, with the transmission in PARK (P).
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 or deflating the tire, the TPM sensor
may be in a inoperative position, preventing the
TPM 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.

Enhanced Accident Response System
Reset Procedure
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.
Maintaining Your Air Bag System Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is
to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less. The EDR in this vehicle is designed to
record such data as:
How various systems in your vehicle were
operating;
Whether or not the driver and passenger
safety belts were buckled/fastened;
How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
WARNING!
Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag system
is not there to protect you. Do not modify
the components or wiring, including adding
any kind of badges or stickers to the
steering wheel hub trim cover or the upper
passenger side of the instrument panel. Do
not modify the front bumper, vehicle body
structure, or add aftermarket side steps or
running boards.
It is dangerous to try to repair any part of
the air bag system yourself. Be sure to tell
anyone who works on your vehicle that it
has an air bag system.
Do not attempt to modify any part of your
air bag system. The air bag may inflate acci -
dentally or may not function properly if
modifications are made. Take your vehicle
to an authorized dealer for any air bag
system service. If your seat, including your
trim cover and cushion, needs to be
serviced in any way (including removal or
loosening/tightening of seat attachment
bolts), take the vehicle to an authorized
dealer. Only manufacturer approved seat
accessories may be used. If it is necessary
to modify the air bag system for persons
with disabilities, contact an authorized
dealer.

The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each time
the vehicle is raised for lubrication or oil
change. Replace as required.
SAFETY CHECKS YOU SHOULD MAKE
I
NSIDE THE VEHICLE
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning light will turn on for four
to eight seconds as a bulb check when the
ignition switch is first turned to ON/RUN. If the
light is either not on during starting, stays on, or
turns on while driving, have the system
inspected at an authorized dealer as soon as
possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air Bag System has been detected. It will
stay on until the fault is removed. If the light
comes on intermittently or remains on while
driving, have an authorized dealer service the
vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed. You
should be able to feel the air directed against
the windshield. See an authorized dealer for
service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelerator,
brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat
fasteners so it cannot slip out of position and
interfere with the accelerator, brake or clutch
pedals or impair safe operation of your vehicle
in other ways.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.
