JEEP GRAND CHEROKEE 2010 Owner handbook (in English)

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 installa-
tion of a hitch, such as reduced detection
range, please see your authorized dealer for
service.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel. There
will 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
In turns or bends, ACC may detect a vehicle
ahead too late or too early. This may cause your
vehicle to brake late or unexpectedly. Give
extra attention in curves and be ready to apply
the brakes if necessary. Be sure to select an
appropriate speed while driving in curves.
ACC may occasionally provide braking and/or
a driver alert that you consider unnecessary.
This may be the system’s 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.
127

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.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.
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.
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. CruiseControl can only be operated if the vehicle
speed is above 25 mph (40 km/h).
To change modes, press the MODE button
when the system is in either the OFF, READY, or
SET position. “Cruise Ready” will be displayed
if the system was in ACC READY or ACC SET
position. “Cruise Off” will be displayed if the
system was in the ACC OFF position. To switch
back to Adaptive Cruise Control mode, press
the MODE button a second time.
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 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.
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 1 mph (1 km/h)
increments respectively. Hold the RES +or
SET -button for 5 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.
129

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 and release the ON/OFF button.
• You turn off the ignition.
• You switch off ESC.
• 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 visual warning is displayed on the
EVIC, and an audible warning is also provided.
When the system determines a collision with
the vehicle in front of you is no longer probable,
the warning message will be deactivated.
WARNING!
Forward Collision Warning (FCW) is not in-
tended to avoid a collision on its own. The
driver has the responsibility to avoid a colli-
sion by controlling the vehicle via braking and
steering. Failure to follow this warning could
lead to serious injury or death.
FCW Message
130

Changing FCW status (Forward Alert Timing)The FCW feature can be set to Far, set to Near
or turned Off by changing the Forward Alert
Timing 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.
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.
Display Warnings and Maintenance
“Clean Radar Sensor In Front Of Vehicle”
Warning
The FCW “Clean Radar Sensor In Front Of
Vehicle” warning will display when conditions
temporarily limit system performance. This
most often occurs at times of poor visibility,
such as in snow or heavy rain. The FCW system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the EVIC will display “Clean Radar Sen-
sor In Front Of Vehicle” and the system will
deactivate.
Example Only
FCW Off Example
131

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.
PARKSENSEPARK 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 approxi-
mately 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).
ACC/FCW Unavailable Warning

ParkSenseSensorsThe 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.

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:

Enabling and Disabling ParkSense ParkSensecan be enabled and disabled with
a switch located in the switch bank of the
instrument panel or through the Customer-
Programmable Features section of the EVIC.
The available choices are: OFF, Sound Only, or
Sound and Display. Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Settings (Customer-Programmable Features)” in “Un-
derstanding Your Instrument Panel” for further
information.
When the Park Sense switch is
pressed to disable the system, the
instrument cluster will display the
“PARK ASSIST OFF” message for
approximately five seconds. Refer
to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instru-
ment Panel” for further information. 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 AS-
SIST 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.
The ParkSense system uses four sensors lo-
cated in the rear bumper fascia to scan for
obstacles up to 79 in (200 cm) away from the
rear bumper fascia. The ParkSense system
135

uses six sensors located in the front bumper
fascia to scan for obstacles up to 47 in
(120 cm) away from the front bumper fascia.
The warning display located above in the In-
strument Cluster’s EVIC provides both visible
and audible warnings to indicate the range of
the object.
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 “REAR SEN-
SOR BLINDED” message when any of the rear
sensor(s) is blocked by snow, mud, or ice and
the vehicle is shifted into REVERSE or DRIVE.
The instrument cluster will display the “CLEAN
PARK ASSIST SENSORS” message when any
of the 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
“SERVICE 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” message 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) and the rear fascia/bumper
or front fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction, see
your authorized dealer. If “SERVICE PARK AS-
SIST SYSTEM” appears in the EVIC, see your
authorized 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
OFF.” Furthermore, once you turn Park-
Sense 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 OFF” mes-
sage 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.
