JEEP GRAND CHEROKEE 2012 Owner handbook (in English)

ACC may occasionally provide braking and/or
a driver alert that you consider unnecessary.
This may be the systems response to signs,
guardrails, and other stationary objects in a
curve. This may also occur at the base of steep
hills. This is normal operation and your vehicle
does not require service.Using ACC On Hills
When driving on hills, ACC may not detect a
vehicle in your lane. Depending on the speed,
vehicle load, traffic conditions, and the steep-
ness of the hills, ACC performance may be
limited.
Lane Changing
ACC will not detect a vehicle until it is com-
pletely in the lane in which you are traveling. In
the illustration shown, ACC has not yet de-
tected the vehicle changing lanes and it may
not detect the vehicle until it’s too late for the
ACC system to take action. ACC will not detect
a vehicle until it is completely in the lane. There
will not be sufficient distance to the lane-
changing vehicle. Always be attentive and
ready to apply the brakes if necessary.
127

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 will 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) 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
normal Cruise Control mode is designed to
maintain a set cruising speed without requiring
the driver to operate the accelerator. Cruise
Control can only be operated if the vehicle
speed is above 18 mph (30 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 addi-
tion, 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
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.
128

To Vary The Speed Setting
There are two ways to change the set speed:
•Use the accelerator pedal to adjust the ve-
hicle to the desired speed and press the SET
-button.
• Tap the RES +or SET -button to increase or
decrease the set speed in 0.6 mph (1 km/h)
increments respectively. Hold the RES +or
SET -button for 6 mph (10 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 ON/OFF button.
• You turn off the ignition.
• You engage Four-Wheel Drive Low.
If the Cruise Control system is turned off and
reactivated, the system will return to the last
driver setting (ACC or Normal Cruise Control).
Forward Collision Warning — If
Equipped
Forward Collision Warning (FCW) warns the
driver of a potential collision with the vehicle in
front of you and prompts the driver to take
action in order to avoid the 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 ve- hicle in front of you is no longer probable, the
warning message will be deactivated.
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 prediction. This is ex-
pected and is a part of normal FCW activation
and functionality.
NOTE:
The minimum speed for FCW activation is
10 mph (16 km/h).
FCW Message
129

WARNING!
Forward Collision Warning (FCW) is not in-
tended 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.
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.
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
normal conditions, have the system checked
by an authorized dealer.
PARKSENSE 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.FCW Off Example
ACC/FCW Unavailable Warning
131

ParkSensewill 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 11 mph
(18 km/h) or above. The system will become
active again if the vehicle speed is decreased
to speeds less than approximately 10 mph
(16 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 ap-
proximately 12 in (30 cm) up to 79 in (200 cm)
from the rear fascia/bumper in the horizontal
direction, depending on the location, type and
orientation 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 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.
Park Assist Display
132

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:

When the ParkSense switch is
pressed to disable the system, the
instrument cluster will display the
“PARK ASSIST SYSTEM OFF”
message for approximately five
seconds. Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in- formation. When the shift lever is moved to
REVERSE or to DRIVE (at or below
11 mph/18 km/h) and the system is disabled,
the EVIC will display the “PARK ASSIST SYS-
TEM OFF” message for as long as the vehicle is
in REVERSE or for five seconds when the
vehicle is in DRIVE.
The ParkSense
switch LED will be ON when
ParkSense is disabled or defective. The Park-
Sense switch LED will be OFF when the
system is enabled.

Service The ParkSensePark Assist
System
When the ParkSense Park Assist System is
malfunctioning, the instrument cluster will actu-
ate a single chime, once per ignition cycle. The
instrument cluster will display the “CLEAN
PARK ASSIST SENSORS” message when any
of the rear or front sensor(s) is blocked by
snow, mud, or ice and the vehicle is shifted into
REVERSE or DRIVE.
The instrument cluster will display the “SER-
VICE PARK ASSIST SYSTEM” message when
any of the rear or front sensors are damaged
and require service. When the shift lever is
moved to REVERSE or DRIVE and the system
has detected a faulted condition, the EVIC will
display the “CLEAN PARK ASSIST SENSORS”
or the “SERVICE PARK ASSIST SYSTEM” mes-
sage for as long as the vehicle is in REVERSE
or DRIVE (at speeds less than
11 mph/18 km/h). Under this condition Park-
Sense will not operate. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in-
formation. If the “CLEAN PARK ASSIST SENSORS” mes-
sage appears in the Electronic Vehicle Informa-
tion Center (EVIC) make sure the rear fascia/
bumper and/or front fascia/bumper is clean
and clear of snow, ice, mud, dirt or other
obstruction, and then cycle the ignition. If the
message continues to appear, see an autho-
rized dealer.
Cleaning The ParkSense
SystemClean 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 sen-
sors. Otherwise, you could damage the sen-
sors.
ParkSense System Usage
Precautions
NOTE:
• Ensure that the front and rear bumper are
free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating
properly.
• Jackhammers, large trucks, and other vi-
brations could affect the performance of
ParkSense. •
When you turn ParkSense off, the instru-
ment cluster will display “PARK ASSIST
SYSTEM OFF.” Furthermore, once you
turn ParkSense off, it remains off until
you turn it on again, even if you cycle the
ignition key.
• When you move the shift lever to the
REVERSE or DRIVE position and Park-
Sense is turned off, the instrument clus-
ter will display “PARK ASSIST SYSTEM
OFF” message for as long as the vehicle
is in REVERSE and when the vehicle is in
DRIVE at or below 11 mph (18 km/h).
• ParkSense, when on, will MUTE 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 be-
hind or in front of the fascia/bumper, or it
could provide a false indication that an
obstacle is behind or in front of the fascia/
bumper.
135

•Objects such as bicycle carriers, trailer
hitches, etc., must not be placed within
12 in (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so
can result in the system misinterpreting a
close object as a sensor problem, caus-
ing the “SERVICE PARK ASSIST SYS-
TEM” message to be displayed in the
instrument cluster.
• On vehicles equipped with a tailgate,
ParkSense should be disabled when the
tailgate is in the lowered or open position.
A lowered tailgate could provide a false
indication that an obstacle is behind the
vehicle.
CAUTION!
• ParkSense is only a parking aid and it is
unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sen-
sors will not be detected when they are in
close proximity.
(Continued)
CAUTION!(Continued)
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is detected.
When backing up, it is recommended that
the driver looks over his/her shoulder when
using ParkSense.
WARNING!
• Drivers must be careful when backing up
even when using the ParkSense Park
Assist System. Always check carefully be-
hind your vehicle, look behind you, and be
sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. You are respon-
sible for safety and must continue to pay
attention to your surroundings. Failure to
do so can result in serious injury or death.
(Continued)
WARNING!(Continued)
• Before using the ParkSense Park Assist
System, it is strongly recommended that
the ball mount and hitch ball assembly is
disconnected from the vehicle when the
vehicle is not used for towing. Failure to do
so can result in injury or damage to ve-
hicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia when the warning display turns
on the single flashing arc and 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.
PARKVIEW REAR BACK UP
CAMERA — IF EQUIPPED
Your vehicle may be equipped with the Park-
View Rear Back Up Camera that allows you to
see an on-screen image of the rear surround-
ings of your vehicle whenever the shift lever is
put into REVERSE. The image will be displayed
