•ParkSense should be disabled when the liftgate is in the
open position and the vehicle is in REVERSE. An open
liftgate could provide a false indication that an obstacle
is behind the vehicle.
WARNING!
• Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind
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.
• Before using ParkSense, 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 obstacles because the
hitch ball will be much closer to the obstacle than the
rear fascia when the loudspeaker sounds the con-
tinuous tone. 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.
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.
328 STARTING AND OPERATING

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 will not be available if ESC is not
available.
• 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 will not be available if
vehicle is in 4LO transfer case mode.
• 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.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected ob-
stacles when backing up in REVERSE gear.
NOTE:
• The driver is always responsible for controlling the
vehicle.
• The system is provided to assist the driver and not to
substitute the driver.
• The driver must stay in full control of the vehicle’s
acceleration and braking and is responsible for the
vehicle’s movements.
Refer to ParkSense System Usage Precautions for limita-
tions of this system and recommendations.
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 gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these

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
6
STARTING AND OPERATING 339

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).
• New vehicles from the dealership must have at least 30
miles accumulated before the ParkSense Active Park
Assist system is fully calibrated and performs accurately.
This is due to the system’s dynamic vehicle calibration to improve the performance of the feature. The system
will also continuously perform the dynamic vehicle
calibration to account for differences such as over or
under inflated tires and new tires.
Enabling And Disabling The ParkSense Active Park
Assist System
The ParkSense Active Park Assist system can be enabled
and disabled with the ParkSense Active Park Assist switch,
located on the switch panel below the Uconnect display.
To enable the ParkSense Active Park Assist system, push the
ParkSense Active Park Assist switch once (LED turns on).
ParkSense Active Park Assist Switch Location
340 STARTING AND OPERATING

When pushed, the LED on the ParkSense Active Park
Assist switch will blink momentarily, and then the LED
will turn off if any of the above conditions are not present.
Parallel Parking Space Assistance Operation/
Display
When the ParkSense Active Park Assist system is enabled
the “Active ParkSense Searching - Push OK to Switch to
Perpendicular” message will appear in the instrument
cluster display. You may switch to perpendicular parking if
you desire. Push the OK button on the left side steering
wheel switch to change your parking space setting.
NOTE:
•When searching for a parking space, use the turn signal
indicator to select which side of the vehicle you want to
perform the parking maneuver. The ParkSense Active
Park Assist system will automatically search for a park-
ing space on the passenger’s side of the vehicle if the
turn signal is not activated.
• The driver needs to make sure that the selected parking
space for the maneuver remains free and clear of any
obstructions (e.g. pedestrians, bicycles, etc.).
• The driver is responsible to ensure that the selected
parking space is suitable for the maneuver and free/ clear of anything that may be overhanging or protruding
into the parking space (e.g., ladders, tailgates, etc. from
surrounding objects/vehicles).
• When seeking for a parking space, the driver should
drive as parallel or perpendicular (depending on the
type of maneuver) to other vehicles as possible.
• The feature will only indicate the last detected parking
space (example: if passing multiple available parking
spaces, the system will only indicate the last detected
parking space for the maneuver).
Active ParkSense Searching
342 STARTING AND OPERATING

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. •
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.
