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, see Ú page 98 for further information.
If disabling HSA using Uconnect Settings, see
Úpage 204 for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Rain Brake Support (RBS)
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)
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)
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 accel -
eration, 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 transmission in
PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.

262SAFETY
If a Forward Collision Warning with Mitigation event
begins at a speed below 39 mph (62 km/h), the
system may provide maximum braking to mitigate
the potential forward collision. If the Forward
Collision Warning with Mitigation event stops the
vehicle completely, the system will hold the vehicle
at a 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 Ú page 408.
NOTE:
The minimum speed for FCW activation is
3 mph (5 km/h).
The FCW alerts may be triggered on objects
other than vehicles, such as guardrails 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 deacti -
vated 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 unnec -
essary warnings to the surroundings. If the
vehicle enters 4WD Low, the FCW system will be
automatically deactivated.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Ú page 204.
NOTE:
The default sensitivity of FCW is the “Medium”
setting and the system status is “Warning &
Braking”. This allows the system to warn the
driver of a possible collision with the vehicle in
front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to the “Far” setting
allows the system to warn the driver of a
possible collision with the vehicle in front using
an audible/visual warning when the latter is at a
farther distance than the “Medium” setting. This
provides the most reaction time to avoid a
possible collision.
The “Far” setting may result in a greater number
of FCW possible collision warnings experienced.
Changing the FCW status to the “Near” setting
allows the system to warn the driver of a
possible collision with the vehicle in front when
the distance between the vehicle in the front is
much closer. This setting provides less reaction
time than the “Far” and “Medium” settings,
which allows for a more dynamic driving experi -
ence.
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.

SAFETY269
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 ≥15 psi to XX 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 user is required to
wait until the hazard lights STOP flashing or 26-30
seconds after the desired pressure is achieved in
one wheel before switching to another.
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 overinflated or over-deflated.
3. The horn will chirp once again when enough air is added or removed to reach proper selected
pressure level.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others. If
you are not sure, ask an authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in
the appropriate child restraint or
belt-positioning booster seat in a rear seating
position Ú page 289.

IN CASE OF EMERGENCY327
NOTE:
You must ensure that the Auto Park Brake
Úpage 123 feature is disabled before towing
this vehicle to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the customer
programmable features in the Uconnect
Settings.
Vehicles with a discharged battery, or total elec -
trical failure when the Electric Park Brake (EPB)
is engaged, will need a wheel dolly or jack to
raise the rear wheels off the ground when
moving the vehicle onto a flatbed.
The Safehold feature will engage the Electric
Park Brake whenever the driver's door is
opened (if the battery is connected, ignition is
ON, transmission is not in PARK, and brake
pedal is released). If you are towing this vehicle
with the ignition in the ON/RUN mode, you must
manually disable the Electric Park Brake each
time the driver's door is opened by pressing the
brake pedal and then releasing the EPB. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of PARK
(P) in order to move the vehicle Ú
page 323.
REAR-WHEEL DRIVE MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be towed
(with rear wheels off the ground) under the
following conditions:
The transmission must be in NEUTRAL (N). For
instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú page 323.
The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed 30 miles
(48 km).
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension
components. If vehicle is equipped with
Quadra-lift air suspension, secure vehicle only
with tire/wheel straps (no suspension compo -
nents or body) to prevent air suspension from
adjusting during towing against securement
straps and causing damage. Damage to your
vehicle may result from improper towing.
CAUTION!
Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe trans -
mission damage. Damage from improper
towing is not covered under the New Vehicle
Limited Warranty.

392SERVICING AND MAINTENANCE
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
TEMPERATURE GRADES
The Temperature grades are A (the
highest), B, and C, representing the tire's
resistance to the generation of heat and
its ability to dissipate heat, when tested
under controlled conditions on a
specified indoor laboratory test wheel. Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance, which all
passenger vehicle tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel, than the
minimum required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than three
weeks, we recommend that you take the following
steps to minimize the drain on your vehicle's
battery:
Disconnect the negative cable from battery.
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
Vehicle body care requirements vary according to
geographic locations and usage. Chemicals that
make roads passable in snow and ice and those
that are sprayed on trees and road surfaces during
other seasons are highly corrosive to the metal in
your vehicle. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on
which the vehicle is operated, extreme hot or cold
weather and other extreme conditions will have an
adverse effect on paint, metal trim, and underbody
protection.
WARNING!
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated and
not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
