2007 JEEP GRAND CHEROKEE display

In this mode, ESP and TCS, except for the “limited slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At 40
mph (64 km/h) the system returns to “Partial Off” mode,
described above. When the vehicle speed drops below 35
mph (56 km/h) the ESP system shuts off. ESP is off at low
vehicle speeds so that it will not interfere with off-road
driving but ESP function returns to provide the stability
feature at speeds above 40 mph (64 km/h). The “ESP/
TCS Indicator Light” will always be illuminated when
ESP is off. To turn ESP on again, momentarily depress the
“ESP Control Switch”. This will restore the normal “ESP
On” mode of operation.
NOTE:The “ESP OFF” message will display and the
audible chime will sound when the gear selector is
placed into the “P” (Park) position from any position
other than “P” (Park), and then moved out of the “P”
(Park) position. This will occur even if the message was
previously cleared.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The “Full Off” ESP mode is intended for
off-highway or off-road use only.
4WD Low Range
Full Off
This is the normal operating mode for ESP in 4WD low
range. Whenever the vehicle is started in 4WD low range,
or the transfer case (if equipped) is shifted from 4WD
high range or neutral to 4WD low range, the ESP system
will be in this mode. In 4WD low range, ESP and TCS,
except for the “limited slip” feature described in the TCS
section, are turned off until the vehicle reaches a speed of

40 mph (64 km/h). At 40 mph (64 km/h), the normal ESP
stability function returns but TCS remains off. When the
vehicle speed drops below 35 mph (56 km/h), the ESP
system shuts off. ESP is off at low vehicle speeds in 4WD
low range so that it will not interfere with off-road
driving but ESP function returns to provide the stability
feature at speeds above 40 mph (64 km/h). TheESP/

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.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.Rear Park Assist Display

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.
Enable/Disable the Rear Park Assist System
The Rear Park Assist System can be enabled and disabled
with a switch located in the switch bank of the instru-
ment panel.

When the switch is pressed to disable the system, the
instrument cluster will display thePARK ASSIST DIS-
ABLEDmessage. Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in Section 4 of this manual. When the
shifter is changed to R (Reverse) and the system isdisabled, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
message.
The Rear Park Assist Switch LED will be ON when the
Rear Park Assist System is disabled or defective. The
Rear Park Assist Switch LED will be OFF when the
system is enabled.
Service the Rear Park Assist System
When the Rear Park Assist System is defective, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display theSERVICE PARK
ASSIST SYSTEMmessage. Refer to “Electronic Vehicle
Information Center (EVIC)” in Section 4 of this manual.

WARNING!
•Drivers 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.
•Before 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 theSERVICE PARK ASSIST
SYSTEMmessage 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.
