2015 JEEP CHEROKEE brake sensor

ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor and a forward facing camera designed to detect a
vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.
WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the vehicle
ahead; and, most importantly, brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.
•The ACC system:
•Does not react to pedestrians, oncoming vehicles,
and stationary objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).

To Turn Off
The system will turn off and erase the set speed in
memory if:
•The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pressed.
•The ignition is turned off.
•You engage Four-Wheel Drive Low.
•The Adaptive Cruise Control (ACC) On/Off button is
pressed.
FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC/DID), 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 forward
looking sensors as well as the 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 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 to help slow the vehicle
and mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system deter-
mines that the driver intends to avoid the collision by

•Before using ParkSense®, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is disconnected from the vehicle when the
vehicle is not used for towing. Failure to do so can
result in injury or damage to vehicles or obstacles
because the hitch ball will be much closer to the
obstacle than the rear fascia when the loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
PARKSENSE® FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense® Park Assist system provides visual and
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
If your vehicle is equipped with an Automatic Transmis-
sion, the vehicle brakes may be automatically applied
and released when performing a reverse parking maneu-
ver if the system detects a possible collision with an
obstacle.
NOTE:
•The driver can override the automatic braking func-
tion by pressing the gas pedal, turning ParkSense® off
via ParkSense® switch, or changing the gear while the
automatic brakes are being applied.
•Automatic brakes will not be available if ESC is not
available.
•Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense® Park
Assist system or the Braking System Module.

PARKSENSE® ACTIVE PARK ASSIST SYSTEM —
IF EQUIPPED
The ParkSense® Active Park Assist system is intended to
assist the driver during parallel and perpendicular park-
ing maneuvers by identifying a proper parking space,
providing audible/visual instructions, and controlling
the steering wheel. The ParkSense® Active Park Assist
system is defined as “semi-automatic” since the driver
maintains control of the accelerator, shift lever and
brakes. Depending on the driver’s parking maneuver
selection, the ParkSense® Active Park Assist system is
capable of maneuvering a vehicle into a parallel or a
perpendicular parking space on either side (i.e., driver
side or passenger side).
NOTE:
•The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
•The system is provided to assist the driver and not to
substitute the driver.
•During a semi-automatic maneuver, if the driver
touches the steering wheel after being instructed to

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 appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more 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” lo-
cated in the instrument cluster will start to flash as soon
as the tires lose traction and 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” begins 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!
The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent col-
lisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent collisions.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user ’s safety or the safety
of others.
534 STARTING AND OPERATING

when ESC becomes inactive following the maneuver
that caused the ESC activation.
The#ESC OFF Indicator Light#indicates the
Electronic Stability Control (ESC) is partially
off or full off.
Trailer Sway Control (TSC)
The TSC system uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the appro-
priate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the
appropriate wheel(s) to counteract the sway of the trailer.
TSC will become active automatically once an excessively
swaying trailer is recognized.
Always use caution when towing a trailer and follow the
trailer tongue weight recommendations. 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
only active in the default “ESC On” mode. TSC can be
disabled by pressing the “ESC Off” switch and entering
“ESC Partial Off” mode. It is not active in the “ESC
Partial Off” or “ESC Full Off” modes. Refer to the ESC
portion of this section for an explanation of the different
ESC operating modes.
NOTE:TSC cannot stop all trailers from swaying.
WARNING!
If the TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
