CAUTION!
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the PARK position. If the
windshield wiper switch is turned off, and
the blades cannot return to the PARK
position, damage to the wiper motor may
occur.
Rain Sensor
This feature senses moisture on the wind-
shield and automatically activates the wipers
for the driver. The feature is especially useful
for road splash or overspray from the wind-
shield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of
four settings to activate this feature.
Automatic Wiping
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay po-
sition one is the least sensitive, and wiper
delay position four is the most sensitive.
Setting three should be used for normal rain
conditions. Settings one and two can be used
if the driver desires less wiper sensitivity.Setting four can be used if the driver desires
more sensitivity. Place the wiper switch in the
OFF position when not using the system.
NOTE:
• The Rain Sensing feature will not operate
when the wiper switch is in the low or
high-speed position.
• The Rain Sensing feature may not function properly when ice, or dried salt water is
present on the windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing per-
formance.
• The Rain Sensing feature can be turned on and off using the Uconnect System, refer
to “Uconnect Settings” in “Multimedia”
in the Owners Manual at
www.jeep.com/en/owners/manuals/ for
further information.
The Rain Sensing system has protection fea-
tures for the wiper blades and arms, and will
not operate under the following conditions: •
Low Ambient Temperature — When the ig-
nition is first turned ON, the Rain Sensing
system will not operate until the wiper
switch is moved, vehicle speed is greater
than 0 mph (0 km/h), or the outside tem-
perature is greater than 32°F (0°C).
• Transmission In NEUTRAL Position — When
the ignition is ON, and the automatic
transmission is in the NEUTRAL position,
the Rain Sensing system will not operate
until the wiper switch is moved, vehicle
speed is greater than 3 mph (5 km/h), or
the gear selector is moved out of the NEU-
TRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with Remote Starting system, Rain
Sensing wipers are not operational when the
vehicle is in the remote start mode. Once the
operator is in the vehicle and has placed the
ignition switch in the RUN position, rain
sensing wiper operation can resume, if it has
been selected, and no other inhibit condi-
tions (mentioned previously) exist.

When the liftgate button on the key fob is
pushed two times, the turn signals will flash
twice to signal that the liftgate is opening or
closing (if Flash Lamps with Lock is enabled in
the Uconnect settings), and the liftgate chime
will be audible. Refer to "Uconnect Settings" in
"Multimedia” for further information.
NOTE:
• In the event of a power malfunction to theliftgate, an emergency liftgate latch re-
lease can be used to open the liftgate. The
emergency liftgate latch release can be
accessed through a snap-in cover located
on the liftgate trim panel.
• If liftgate is left open for an extended period of time, the liftgate may need to be
closed manually to reset power liftgate
functionality.
WARNING!
During power operation, personal injury or
cargo damage may occur. Ensure the lift-
gate travel path is clear. Make sure the
liftgate is closed and latched before driv-
ing away. NOTE:
• The power liftgate buttons will not operate
if the vehicle is in gear or the vehicle
speed is above 0 MPH (0 km/h).
• The power liftgate will not operate in tem- peratures below −22°F (−30°C) or tem-
peratures above 150° F (65° C). Be sure to
remove any buildup of snow or ice from the
liftgate before pushing any of the power
liftgate switches.
• If anything obstructs the power liftgate while it is closing or opening, the liftgate
will automatically reverse to the closed or
open position, provided it meets sufficient
resistance.
• There are also pinch sensors attached to the side of the liftgate. Light pressure
anywhere along these strips will cause the
liftgate to return to the open position.
• If the liftgate is not fully open, push the liftgate button on the key fob twice to
operate the liftgate.
• If the electronic liftgate release is pushed while the power liftgate is closing, the
liftgate will reverse to the full open posi-
tion. • If the electronic liftgate release is pushed
while the power liftgate is opening, the
liftgate motor will disengage to allow
manual operation.
• If the power liftgate encounters multiple obstructions within the same cycle, the
system will automatically stop and the
liftgate must be opened or closed
manually.
WARNING!
• Driving with the liftgate open can allowpoisonous exhaust gases into your ve-
hicle. You and your passengers could be
injured by these fumes. Keep the liftgate
closed when you are operating the ve-
hicle.
• If you are required to drive with the
liftgate open, make sure that all win-
dows are closed, and the climate control
blower switch is set at high speed. Do
not use the recirculation mode.

Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tiresor wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealer to have your sensor
function checked.

ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
• Oversteer - when the vehicle is turningmore than appropriate for the steering
wheel position.
• Understeer - when the vehicle is turning less than appropriate for the steering
wheel position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.WARNING!
• Electronic Stability Control (ESC) can- not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents re-
sulting from loss of vehicle control due
to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skill-
ful driver can prevent accidents. The
capabilities of an ESC equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopar-
dize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
WARNING!
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.
ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating modes.
ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode

occurring during severe or evasive driving
maneuvers; it cannot prevent wheel lift due to
other factors, such as road conditions, leav-
ing the roadway, or striking objects or other
vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading,
road conditions and driving conditions,
influence the chance that wheel lift or
rollover may occur. ERM cannot prevent all
wheel lift or roll overs, especially those
that involve leaving the roadway or striking
objects or other vehicles. The capabilities
of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user's
safety or the safety of others.
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 that TSC cannot stop all trailers
from swaying. Always use caution when tow-
ing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer
Towing” in “Starting And Operating” for fur-
ther 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.
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.
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.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the
ESC and EPS modules that provides torque at
the steering wheel for certain driving condi-
tions in which the ESC module is detecting
vehicle instability. The torque that the steer-
ing wheel receives is only meant to help the

• Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of
the following conditions occur:
• The driver pushes the SSC switch.
• The driveline is shifted out of 4WD LowRange.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h) for greater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and
the SSC switch has an LED which offer feed-
back to the driver about the state SSC is in.
• The cluster icon and switch lamp 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 lamp will flash
for several seconds then extinguish when
the driver pushes the SSC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash for several seconds then extinguish when
SSC disables due to excess speed.
• The cluster icon and switch lamp will flash then extinguish when SSC deactivates due
to overheated brakes.
WARNING!
SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off road conditions. The driver must re-
main attentive to the driving conditions
and is responsible for maintaining a safe
vehicle speed.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring
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.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear
bumper of the vehicle. The BSM system
monitors the detection zones on both sides of
the vehicle when the vehicle speed reaches
approximately 6 mph (10 km/h) or higher and
will alert the driver of vehicles in these areas.
103

When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side rear view mirrors to let the driver know
that the system is operational. The BSM
system sensors operate when the vehicle is in
any forward gear or REVERSE and enters
stand by mode when the vehicle is in PARK.
The BSM warning light, located in the out-
side mirrors, will illuminate if a vehicle
moves into a blind spot zone.The BSM system can also be configured to
sound an audible (chime) alert and mute the
radio to notify you of objects that have en-
tered the detection zones.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where the vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the rear end of the vehicle is exposed. The RCP
system will then have a clear view of the cross
traffic and if an oncoming vehicle is de-
tected, will alert the driver. When RCP is on
and the vehicle is in REVERSE, the driver is
alerted using both the visual and audible
alarms, including reducing the radio volume.
Refer to “Blind Spot Monitoring” in “Safety”
in the Owner's Manual at
www.jeep.com/en/owners/manuals/ for more
information.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings/Customer Programmable
Features” in “Multimedia” for further infor-
mation.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the
BSM system will provide a visual alert in the
appropriate side view mirror based on a de-
tected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
Rear Detection Zones
Blind Spot Warning Light

104

system will respond with both visual and
audible alerts when a detected object is pres-
ent. Whenever an audible alert is requested,
the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, the BSM system will provide a
visual alert in the appropriate side view mirror
based on a detected object. If the turn signal
is then activated, and it corresponds to an
alert present on that side of the vehicle, an
audible chime will also be sounded. When-
ever a turn signal and detected object are
present on the same side at the same time,
both the visual and audible alerts will be
issued. In addition to the audible alert the
radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Wheneveran audible alert is requested, the radio is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will
be no visual or audible alerts from either the
BSM or RCP systems.
NOTE:
The BSM system will store the current oper-
ating mode when the vehicle is shut off. Each
time the vehicle is started the previously
stored mode will be recalled and used.
Forward Collision Warning (FCW)
The Forward Collision Warning (FCW) system
provides the driver with audible and visual
warnings within the instrument cluster dis-
play 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 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.
Turning FCW ON Or OFF
The forward collision button is located in the
Uconnect display in the controls settings.
• To turn the FCW system OFF, press the
forward collision button once to turn the
system OFF.
• To turn the FCW system back ON, press the forward collision button again to turn
the system ON.
NOTE:
• The default status of FCW is “On”, this allows the system to warn you of a possible
collision with the vehicle in front of you.
105

Monitoring Telltale Light will turn OFF only
after the tires have been inflated to the vehi-
cle’s recommended cold tire pressure value.
CAUTION!
• The TPMS has been optimized for theoriginal equipment tires and wheels.
TPMS pressures and warnings have
been established for the tire size
equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equip-
ment that is not of the same size, type,
and/or style. Aftermarket wheels can
cause sensor damage. Using aftermar-
ket tire sealants may cause the Tire Pres-
sure Monitoring System (TPMS) sensor
to become inoperable. After using an
aftermarket tire sealant it is recom-
mended that you take your vehicle to an
authorized dealership to have your sen-
sor function checked.
• After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
CAUTION!
could damage the Tire Pressure Monitor-
ing Sensor.
NOTE:
• The TPMS is not intended to replace nor- mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• The TPMS should not be used as a tire pressure gauge while adjusting your tire
pressure.
• Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pres-
sure using an accurate tire gauge, even if
under-inflation has not reached the level
to trigger illumination of the Tire Pressure
Monitoring Telltale Light. • Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Premium System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.
