2013 JEEP GRAND CHEROKEE warning

•Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to
the “Adaptive Cruise Control Off” state and will
resume function by simply reactivating it.
NOTE:
• If the “Clean Radar Sensor In Front Of
Vehicle” message occurs frequently
(e.g. more than once on every trip) with-
out any snow, rain, mud, or other obstruc-
tion, have the radar sensor realigned at
your authorized dealer.
•
Installing a snow plow, front-end protector,
an aftermarket grille or modifying the grille
is not recommended. Doing so may block
the sensor and inhibit ACC operation.
Removing ACC Sensor For Off-Roading
NOTE:
When off-roading, it may be advisable to
remove the ACC sensor. The sensor is lo-
cated behind the front lower grille in the
center of the vehicle. After removing the
lower fascia, you may remove the lower
sensor and bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two
tabs on the connector and pulling it out. Do not
pull by the wiring or use any tools to remove the
connector.
2. Remove the wiring christmas tree attach-
ment from the back of the bracket.
3. Remove the two M6 fasteners that connect
the bracket to the bumper.
NOTE:
Do not change the adjustment fasteners or
pull the sensor off of the bracket. Doing so
may misalign the sensor. Store the sensor and bracket assembly in a
safe location. The wiring and connector must be
stowed properly after the sensor and bracket
assembly is removed.
A connector plug is stowed on top of the bumper
beam. Insert the wiring connector into the con-
nector plug.
NOTE:
When the sensor is removed, Adaptive Cruise
Control, Normal Cruise Control, and Forward
Collision Warning will not be available. The
cluster will display the warning “ACC/FCW
Unavailable - Service Radar Sensor.”
To reinstall the sensor and bracket assembly
reverse the process above. The fastener torque
required to assembly the bracket back to the
beam is 6.6 ft lbs (9 N·m).

ACC Unavailable Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable, Vehicle System Error”,
there may be a temporary malfunction that
limits ACC functionality. Although the vehicle is
still drivable under normal conditions, ACC will
be temporarily unavailable. If this occurs, try
activating ACC again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable Service Radar Sen-
sor”, it indicates there is an internal system fault.
Although the vehicle is still drivable under nor-
mal conditions, have the system checked by an
authorized dealer.
Precautions While Driving With ACCIn certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.Adding A Trailer Hitch
The weight of a trailer/hitch may affect the
performance of ACC. If there is a noticeable
change in performance following the installation
of a trailer/hitch, or if the ACC performance does
not return to normal after removing the trailer/
hitch see your authorized dealer.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle detected. Once the vehicle is out of the
curve the system will resume your original Set
Speed. This is a part of normal ACC system
functionality.
NOTE:
On tight turns ACC performance may be
limited.
128

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.General Information

Normal (Fixed Speed) Cruise
Control Mode
In addition to Adaptive Cruise Control mode, a
normal (fixed speed) Cruise Control mode is
available for cruising at fixed speeds. The nor-
mal Cruise Control mode is designed to main-
tain a set cruising speed without requiring the
driver to operate the accelerator. Cruise Control
can only be operated if the vehicle speed is
above 20 mph (32 km/h).
To change between the different cruise modes,
press the MODE button when the system is in
either the OFF, READY or SET state. Pressing
of the MODE button in any state will result in
changing to the new Mode in the OFF state.
WARNING!
In the normal Cruise Control mode, the sys-
tem will not react to vehicles ahead. In
addition, the proximity warning does not ac-
tivate 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
When the vehicle reaches the speed desired,
press the SET -button and release. The EVIC
will display the set speed.
NOTE:
You must observe the display when setting
or changing speed, not the speedometer.
130

To Vary The Speed Setting
There are two ways to change the set speed:
•
Use the accelerator pedal to adjust the vehicle
to the desired speed and press the SET-
button.
•Tap the RES +or SET -button to increase or
decrease the set speed in 1 mph (1.6 km/h)
increments respectively. Hold the RES +or
SET -button for 5 mph (8 km/h) increments.
To Cancel
The system will disable normal Cruise Control
without erasing the memory if:
• You softly tap or depress the brake pedal.
• You press the CANCEL button.
• The Electronic Stability Control/Traction Con-
trol System (ESC/TCS) activates.
To Resume
Press the RES +button and then remove your
foot from the accelerator pedal. The EVIC will
display the last set speed. To Turn Off
The system will turn off and erase the set speed
in memory if:
•
You push the Normal Fixed Speed ON/OFF
button.
• You turn off the ignition.
• You engage Four-Wheel Drive Low.
Forward Collision Warning — If
Equipped
The Forward Collision Warning (FCW) system
provides the driver with audible and visual
warnings (within the EVIC) when it detects a
potential frontal collision. The warnings are in-
tended to provide the driver with enough time to
react and avoid the potential collision.
FCW monitors the information from the forward
looking sensor as well as the Electronic Brake
Controller (EBC), wheel speed sensors, i.e., to
calculate a probable rear-end collision. When the
system determines that a rear-end collision is
probable a warning message (both audible and
visual) will be displayed on the EVIC. 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
10 mph (16 km/h).
• When entering or driving in a curve, the
FCW alerts may be triggered on objects
other than vehicles such as guard rails or
sign posts based on the course predic-
tion. This is expected and is a part of
normal FCW activation and functionality.
FCW Message
131

WARNING!
Forward Collision Warning (FCW) is not in-
tended to avoid a collision on its own, nor
can FCW detect every type of potential col-
lision. 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.
Changing FCW Status
The FCW feature can be set to far, set to near or
turned off in the Electronic Vehicle Information
Center (EVIC) refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your
Instrument Panel” for further information. The
FCW Status Off, Near or Far will be displayed in
the EVIC.
FCW settings can only be changed when the
vehicle is in PARK. The default status of FCW is the “Far” setting,
this allows the system to warn you of a possible
collision with the vehicle in front of you when
you are farther away. This gives you the most
reaction time.
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 al-
lows for a more dynamic driving experience.

132

Changing the FCW status to “Off” prevents the
system from warning you of a possible collision
with the vehicle in front of you.
NOTE:
In the “Off” setting FCW OFF will be dis-
played in the EVIC.NOTE:
•
The system will retain the last setting
selected by the driver after ignition shut
down.
• FCW will not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the car,
stationary objects that are far away, on-
coming traffic, or leading vehicles with
the same or higher rate of speed.
• FCW will be disabled like ACC below with
the unavailable screens. FCW Unavailable Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable, Vehicle System Error”,
there may be a temporary malfunction that
limits FCW functionality. Although the vehicle is
still drivable under normal conditions, FCW will
be temporarily unavailable. If this occurs, try
activating FCW again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service FCW Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable Service Radar Sen-
sor”, it indicates there is an internal system fault.
Although the vehicle is still drivable under nor-
mal conditions, have the system checked by an
authorized dealer.

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. Refer
to ParkSense® System Usage Precautions for
limitations of this system and recommenda-
tions.
ParkSense® will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is changed to the ON/RUN
position.
ParkSense® can be active only when the shift
lever is in REVERSE or DRIVE. If ParkSense®
is enabled at one of these shift lever positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. The system will become
active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
ParkSense® SensorsThe four ParkSense® sensors, located in the
rear fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from approxi-
mately 12 in (30 cm) up to 59 in (150 cm) from
the rear fascia/bumper in the horizontal direc-
tion, depending on the location, type and orien-
tation of the obstacle.
The six ParkSense® sensors, located in the
front fascia/bumper, monitor the area in front of
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 in (30 cm) up to 47 in (120 cm)
from the front fascia/bumper in the horizontal
direction, depending on the location, type and
orientation of the obstacle.
ParkSense® Warning DisplayThe ParkSense® Warning screen will only be
displayed if Sound and Display is selected from
the Customer-Programmable Features section
of the Electronic Vehicle Information Center(EVIC). Refer to “Electronic Vehicle Information
Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding
Your Instrument Panel” for further information.
The ParkSense® Warning Display is located in
the Instrument cluster’s EVIC display. It pro-
vides both visual and audible warnings to indi-
cate the distance between the rear fascia/
bumper and/or front fascia/bumper and the
detected obstacle.
ParkSense® Warning Display

ParkSense® DisplayThe warning display will turn ON indicating the
system status when the vehicle is in REVERSE
or when the vehicle is in DRIVE and an obstacle
has been detected.
The system will indicate a detected obstacle by
showing three solid arcs and will produce a
one-half second tone. As the vehicle moves
closer to the object the EVIC display will show
fewer arcs and the sound tone will change from
slow, to fast, to continuous.The vehicle is close to the obstacle when the
EVIC display shows one flashing arc and
sounds a continuous tone. The following chart
shows the warning alert operation when the
system is detecting an obstacle:
