2016 JEEP GRAND CHEROKEE ignition

Warning with Mitigation event stops the vehicle com-
pletely, the system will hold the vehicle at a standstill for
two seconds and then release the brakes.
When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.NOTE:
•
The minimum speed for FCW activation is 1 mph
(2 km/h).
• The FCW alerts may be triggered on objects other than
vehicles such as guard rails 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 deactivated 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 unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low Range,
the FCW system will be automatically deactivated.
FCW Message
220 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
Turning FCW ON Or OFF
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.
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.
Changing the FCW status to “OFF” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
NOTE:
The FCW system state is kept in memory from
one ignition cycle to the next. If the system is turned OFF,
it will remain off when the vehicle is restarted.
Changing FCW And Active Braking Status
The FCW Sensitivity And Active Braking Settings are
programmable through the Uconnect System. Refer to
“Uconnect Settings” in “Understanding Your Instrument
Panel” for further information.
The default status of FCW is the “Medium” setting and
the Active Braking is in the “On” setting. This allows the
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 221

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 “Far” setting allows the
system to warn the driver of a possible collision with the
vehicle in front using audible/visual warning when the
latter is at a farther distance thanMediumsetting. This
provides the most reaction time to avoid a possible
collision.
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 experience. Changing the Active Braking status to “Off” prevents the
system from providing autonomous braking, or addi-
tional brake support if the driver is not braking ad-
equately in the event of a potential frontal collision.
NOTE:
•
The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects not in the
path of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
• FCW will be disabled like ACC, with the unavailable
screens.

•Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
• The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid collid-
ing with a detected obstacle.
• The automatic braking function may not be applied
fast enough for obstacles that move toward the rear of
the vehicle from the left and/or right sides.
• The automatic braking function can be enabled/
disabled from the Customer-Programmable Features
section of the Uconnect System.
• ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles. The automatic braking function is intended to assist the

stacles when backing up in REVERSE gear.
NOTE:
•
The driver is always responsible for controlling the
vehicle.
• The system is provided to assist the driver and not to
substitute the driver.
• The driver must stay in full control of the vehicle’s
acceleration and braking and is responsible for the
vehicle’s movements.
Refer to ParkSense System Usage Precautions for limita-
tions of this system and recommendations.

Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.
ParkSense System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense system operating
properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
• When you turn ParkSense OFF, the instrument cluster
will display “PARKSENSE OFF” Furthermore, once
you turn ParkSense off, it remains off until you turn it
on again, even if you cycle the ignition. •
When you move the gear selector to the REVERSE
position and ParkSense is turned OFF, the DID will
display “PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
• ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system
OFF if objects such as bicycle carriers, trailer hitches,
etc. are placed within 12 in (30 cm) from the rear
fascia/bumper. Failure to do so can result in the
