JEEP GRAND CHEROKEE 2015 WK2 / 4.G SRT Owners Manual

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There may not be
sufficient distance to the vehicle ahead.
Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and
the vehicle ahead is stopped in your lane. Always be
attentive and ready to apply the brakes if necessary.

Normal (Fixed Speed) Electronic Speed Control
Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Electronic Speed Control mode is available
for cruising at fixed speeds. The Normal (Fixed Speed)
Electronic Speed Control mode is designed to maintain a
set cruising speed without requiring the driver to operate
the accelerator. Electronic Speed Control can only be
operated if the vehicle speed is above 20 mph (32 km/h).
To change between the different control modes, push the
ADAPTIVE CRUISE CONTROL (ACC) ON/OFF button
which turns the ACC and the NORMAL (Fixed Speed)
ELECTRONIC SPEED CONTROL OFF. Pushing of the
NORMAL (Fixed Speed) ELECTRONIC SPEED CON-
TROL ON/OFF button will result in turning ON (chang-
ing to) the Normal (Fixed Speed) Electronic Speed Con-
trol mode.

WARNING!
In the normal Cruise Control mode, the system will
not react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound
even if you are too close to the vehicle ahead since
neither the presence of the vehicle ahead nor the
vehicle-to vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and
the vehicle ahead. Always be aware which mode is
selected.
To Set A Desired Speed
Turn the Normal (Fixed Speed) Electronic
Speed Control ON. When the vehicle has
reached the desired speed, push the SET (+) or
SET (-) button and release. Release the accel-
erator and the vehicle will operate at the selected speed.
Once a speed has been set a message (CRUISE CON-
TROL SET TO MPH/KM) will appear indicating what
speed was set. This light will turn on when the electronic
speed control is SET.
To Vary The Speed Setting
To Increase Speed
When the Normal (Fixed Speed) Electronic Speed Con-
trol is set, you can increase speed by pushing the SET+

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 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.
214 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 progres-
sive 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
braking but has not applied sufficient brake force, the
system will compensate and provide additional brake
force as required.When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.
FCW Message
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 215

NOTE:
•The minimum speed for FCW activation is 5 mph
(8 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.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 on the switch
panel below the Uconnect® display.
To turn the FCW system OFF, push the forward collision
button once to turn the system OFF (led turns on).
216 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To turn the FCW system back ON, push the forward
collision button again to turn the system ON (led turns
off).
Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
Changing the Active Braking status to “Off” prevents the
system from providing limited autonomous braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision.
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 Instru-
ment Panel” for further information.
The default status of FCW is the “Far” setting and the
Active Braking is the “On” setting, this allows the system
to warn you of a possible collision with the vehicle in
front of you when you are farther away and it applies
limited braking. This gives you the most reaction time to
avoid a possible collision.
Changing the FCW status to the “Near” setting, allows
the system to warn you of a possible collision with the
vehicle in front of you when you are much closer. This
setting provides less reaction time than the “Far” setting,
which allows for a more dynamic driving experience.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 217

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 car, 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.
FCW Limited Warning
If the DID displays “ACC/FCW Limited Functionality”
or “ACC/FCW Limited Functionality Clean Front Wind-
shield” momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still drivable
under normal conditions, the active braking may not befully available. Once the condition that limited the sys-
tem performance is no longer present, the system will
return to its full performance state. If the problem per-
sists, see your authorized dealer.
Service FCW Warning
If the system turns off, and the DID displays:
•ACC/FCW Unavailable Service Required
•Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
PARKSENSE® REAR PARK ASSIST — IF
EQUIPPED
The ParkSense® Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
