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.

SAFETY257
Feedback To The Driver:
The instrument cluster has an SSC icon and the
SSC switch has an LED which offer feedback to the
driver about the state SSC is in.
The cluster icon and switch light will illuminate
and remain on solid when SSC is enabled or
activated. This is the normal operating condition
for SSC.
The cluster icon and switch light will flash for
several seconds then extinguish when the driver
pushes the SSC switch but enable conditions
are not met.
The cluster icon and switch light will flash for
several seconds then extinguish when SSC
disables due to excess speed.
The cluster icon and switch light will flash then
extinguish when SSC deactivates due to over -
heated brakes.
Traction Control System (TCS)
The 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 power
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.
TSC will become active automatically once an
excessively swaying trailer is recognized.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations
Ú page 185.
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” mode.
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

278SAFETY
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
first in the ON/RUN position. After the self-check,
the Air Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system
is designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.
The Air Bag Warning Light does not come on
during the four to eight seconds when the igni -
tion switch is first in the ON/RUN position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be disabled. In
this condition the air bags may not be ready to
inflate for your protection. Have an authorized
dealer service the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The
Redundant Air Bag Warning Light will stay on until
the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag
Warning Light has come on and a fault has been
detected. If the Redundant Air Bag Warning Light
comes on intermittently or remains on while driving have an authorized dealer service the vehicle
immediately Ú
page 108.
Front Air Bags
This vehicle has front air bags and lap/shoulder
belts for both the driver and front passenger. The
front air bags are a supplement to the seat belt
restraint systems. The driver front air bag is
mounted in the center of the steering wheel. The
passenger front air bag is mounted in the
instrument panel, above the glove compartment.
The words “SRS AIRBAG” or “AIRBAG” are
embossed on the air bag covers.

Front Air Bag/Knee Bolster Locations

WARNING!

Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system to protect you in a collision.
If the light does not come on as a bulb check
when the ignition is first turned on, stays on
after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service
the air bag system immediately.

IN CASE OF EMERGENCY325
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then, shift
back and forth between DRIVE (D) and REVERSE
(R) while gently pressing the accelerator.
NOTE:Shifts between DRIVE (D) and REVERSE (R) can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE (D) or REVERSE (R).
Use the least amount of accelerator pedal
pressure that will maintain the rocking motion
without spinning the wheels or racing the engine.
NOTE:Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 251.
Once the vehicle has been freed, push the ESC OFF
button again to restore “ESC On” mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when
you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occur -
ring).

Belt broken (identify and correct problem before
new belt is installed)
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools, we recommend having your
vehicle serviced at an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points and
rollers, liftgate, tailgate, decklid, sliding doors and
hood hinges, should be lubricated periodically with
a lithium-based grease, such as Mopar® Spray
White Lube to ensure quiet, easy operation and to
protect against rust and wear. Prior to the
application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit;
after lubricating excess oil and grease should be
removed. Particular attention should also be given
to hood latching components to ensure proper
function. When performing other underhood
services, the hood latch, release mechanism and
safety catch should be cleaned and lubricated. The external lock cylinders should be lubricated
twice a year, preferably in the Autumn and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar® Lock Cylinder Lubricant directly
into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove
accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry windshield.
Avoid using the wiper blades to remove frost or ice
from the windshield. Keep the blade rubber out of
contact with petroleum products such as engine
oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor
performance of blades may be present with chat
-
tering, marks, water lines or wet spots. If any of
these conditions are present, clean the wiper
blades or replace as necessary. The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following points:
Wear or uneven edges
Foreign material
Hardening or cracking
Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace
the affected wiper arm or blade with a new unit. Do
not attempt to repair a wiper arm or blade that is
damaged.
Front Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade in
place or the glass may be damaged.

348SERVICING AND MAINTENANCE
Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT that meets the requirements of the
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of the
manufacturer Material Standard MS.90032
and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
−34°F (−37°C) are anticipated. Please contact
an authorized dealer for assistance.
Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant solution. The use of lower quality water
will reduce the amount of corrosion protection
in the engine cooling system.
NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in the
area where the vehicle is operated.
Use care when filling under hood fluids such as
engine oil, washer fluid, antifreeze, etc., to mini -
mize spillage onto the top of the engine. Any excess fluid that is spilled onto the top of the
engine should be removed using compressed
air or an absorbent cloth.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system, please contact a local authorized
dealer.
Mixing engine coolant types is not recom
-
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank (if
equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground,
clean up any ground spills immediately. If ingested
by a child or pet, seek emergency assistance
immediately.
Coolant Level
The coolant bottle provides a quick visual method
for determining that the coolant level is adequate.
With the engine off and cold, the level of the engine
WARNING!
Do not open a hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
