2007 JEEP GRAND CHEROKEE warning

after several ignition cycles, and the vehicle has been
driven several miles at speeds greater than 30 mph (48
km/h), see your authorized dealer as soon as possible to
have the problem diagnosed and corrected.
NOTE:
²9The9ESP/TCS Indicator Light9and the9ESP/BAS
Warning Lamp9come on momentarily each time the
ignition switch is turned ON.
²Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
²The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
REAR PARK ASSIST SYSTEMÐ IF EQUIPPED
The Rear Park Assist System provides visual and audible
indications of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist System will remember the last
system state (enabled or disabled) from the last ignition
cycle when the ignition is changed to the RUN/ON
position.
The Rear Park Assist System can be active only when the
shifter is in R (Reverse). If the Rear Park Assist System is
enabled at this shifter position, the system will be active
until the vehicle speed is increased to approximately 11
mph (18 km/h) or above. The system will be active again
if the vehicle speed is decreased to speeds less than
approximately 10 mph (16 km/h).

Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors' field of view. The monitored area seems oval
in shape.
The sensors can detect obstacles from approximately 11.8
inches (30 cm) up to 59 inches (150 cm) from the rear
fascia in the horizontal direction, depending on the
location and orientation of the obstacle and the type of
obstacle.
Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visual and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.Rear Park Assist Display
138 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the ignition is changed to the RUN/ON position,
the warning display will turn ON all of its LEDs for
about 1 second. Each side of the warning display has 6
yellow and 2 red LEDs. The vehicle is close to the obstacle
when the red LED is ON.
When the obstacle is detected at a distance of about 59
inches (150 cm) from the rear fascia, the outermost LEDs
of the warning display will be ON with increased bright-
ness. Along with the LED, a half second tone will occur.
As the distance of the detected obstacle to the rear fascia
decreases, more LEDs are illuminated. When the warning
display has the first 5 yellow LEDs ON, the warning
display will actuate an intermittent tone for about 10
seconds. The radio will be muted while the tone is
actuated. The intermittent tone will increase in frequency
as each additional LED is lit.When the detected obstacle is about 11.8 inches (30 cm)
from the rear fascia, the warning display will actuate a
continuous tone for about 10 seconds, and it will turn ON
all 8 LEDs, including both RED LEDs, on the correspond-
ing side of the display. The radio will be muted while the
tone is actuated.
When the obstacle is less than 11.8 inches (30 cm) from
the rear fascia, the warning display will either have all 8
LEDs ON (obstacle detected) or it will have only the
outermost LEDs ON with decreased brightness (obstacle
not detected), depending on the location of the obstacle.

WARNING!
²Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before back-
ing up. You are responsible for safety and must
continue to pay attention to your surroundings. Fail-
ure to do so can result in serious injury or death.
²Before using the Rear 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 vehicles or ob-
stacles because the hitch ball will be much closer to
the obstacle than the rear fascia when the warning
display turns the red LEDs ON. Also, the sensors
could detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
NOTE:Clean all four Rear Park Assist 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 system might not detect an ob-
stacle behind the fascia or it could provide a false
indication that an obstacle is behind the fascia.
Assure objects are not within 11.8 inches (30 cm) from the
rear fascia while driving the vehicle. Failure to do so can
result in the system misinterpreting a close object as a
sensor problem, causing the9SERVICE PARK ASSIST
SYSTEM9message to be displayed in the instrument
cluster.
Ultrasonic noise from airbrakes of nearby trucks, air
powered jackhammers and air powered shop tools, to
name a few, will cause the Rear Park Assist System to be
disabled until the ultrasonic noise is no longer present.

REAR CAMERA Ð IF EQUIPPED
Vehicles with a Navigation radio may be equipped with
a rear view camera (located on the rear liftgate) that
allows you to see an on-screen image (on the navigation
radio screen) of the rear of your vehicle whenever the
vehicle is put into R (Reverse).
WARNING!
Drivers must be careful when backing up even when
using the rear camera system. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. Failure to do so can
result in serious injury or death.
If snow, ice, mud, or anything else builds up on the
camera lens. Clean the lens, rinse with water, and dry
with a soft cloth.

2. Select ªONº at the ªRear Cameraº screen. Highlight
ªDONEº and press ENTER. The rear camera is now
enabled.
3. When the vehicle is shifted into R (Reverse), the
CAUTION screen will appear, followed by an image of
the rear of the vehicle.
4. When the vehicle is shifted out of R (Reverse), the rear
camera mode is exited and the Navigation or Audio
screen appears again.
