brake JEEP GRAND CHEROKEE LIMITED 2019 Repair Manual

CAUTION!
•ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
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. If your
vehicle is equipped with an automatic transmission, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the sys-
tem detects a possible collision with an obstacle. NOTE:
•
The driver can override the automatic braking function
by pressing the gas pedal, turning ParkSense off via
ParkSense switch, or changing the gear while the auto-
matic brakes are being applied.
• Automatic brakes are not available if the vehicle is in
4LO.
• Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
• The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
• The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
• The automatic braking function can be enabled/
disabled from the Customer Programmable Features
section of the Uconnect System.
• ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles.

PARKSENSE ACTIVE PARK ASSIST SYSTEM — IF
EQUIPPED
The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space, provid-
ing audible/visual instructions, and controlling the steer-
ing wheel. The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver maintains control of the accelerator, gear selector and brakes. De-
pending on the driver’s parking maneuver selection, the
ParkSense Active Park Assist system is capable of maneu-
vering a vehicle into a parallel or a perpendicular parking
space on either side (i.e., driver side or passenger side).
NOTE:
•
The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
• The system is provided to assist the driver and not to
substitute the driver.
• During a semi-automatic maneuver, if the driver touches
the steering wheel after being instructed to remove their
hands from the steering wheel, the system will cancel,
and the driver will be required to manually complete the
parking maneuver.
• The system may not work in all conditions (e.g. envi-
ronmental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that will
absorb the ultrasonic sensor waves).
332 STARTING AND OPERATING

When the driver places the gear selector into the REVERSE
position, the system may instruct the driver to wait for
steering to complete.The system will then instruct the driver to check their
surroundings and move backward.
NOTE:
•
It is the driver ’s responsibility to use the brake and
accelerator during the semi-automatic parking maneu-
ver.
• When the system instructs the driver to remove their
hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.

STARTING AND OPERATING 337

•The ParkSense Active Park Assist system will allow a
maximum of six shifts between DRIVE and REVERSE. If
the maneuver cannot be completed within six shifts, the
system will cancel and the instrument cluster display
will instruct the driver to complete the maneuver manu-
ally.
• The system will cancel the maneuver if the vehicle speed
exceeds 5 mph (7 km/h) during active steering guidance
into the parking space. The system will provide a
warning to the driver at 3 mph (5 km/h) that tells them
to slow down. The driver is then responsible for com-
pleting the maneuver if the system is canceled.
• If the system is canceled during the maneuver for any
reason, the driver must take control of the vehicle.
When the vehicle has reached the end of its backward
movement, the system will instruct the driver to check
their surroundings and stop the vehicle’s movement. NOTE:
It is the driver’s responsibility to use the brake and
stop the vehicle. The driver should check their surround-
ings and be prepared to stop the vehicle either when
instructed to, or when driver intervention is required.

The system will then instruct the driver to check their
surroundings and move forward.When the vehicle has reached the end of its forward
movement, the system will instruct the driver to check
their surroundings and stop the vehicle’s movement.

Changing LaneSense Status
The LaneSense system has settings to adjust the intensity of
the torque warning and the warning zone sensitivity
(early/late) that you can configure through the Uconnect
system screen. Refer to “Uconnect Settings” in “Multime-
dia” for further information.
NOTE:
•When enabled the system operates above 37 mph
(60 km/h) and below 112 mph (180 km/h).
• Use of the turn signal suppresses the warnings.
• The system will not apply torque to the steering wheel
whenever a safety system engages (anti-lock brakes,
traction control system, electronic stability control, for-
ward collision warning, etc.).
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to see an
on-screen image of the rear surroundings of your vehicle
whenever the gear selector is put into REVERSE. The
image will be displayed on the Navigation/Multimedia
radio display screen along with a caution note to “check
entire surroundings” across the top of the screen. After five seconds this note will disappear. The ParkView camera is
located on the rear of the vehicle above the rear license
plate.
When the vehicle is shifted out of REVERSE (with camera
delay turned off), the rear camera mode is exited and the
navigation or audio screen appears again.
Manual Activation Of The Rear View Camera
