PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. If your vehicle is equipped with an Automatic Transmission, the vehicle brakes may be auto-
matically applied and released when performing a reverse
parking maneuver if the system 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 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 may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
6
STARTING AND OPERATING 319

•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.

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

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.
