heavy traffic, and complex driving situations (i.e., in
highway construction zones).
• When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy, snow-
covered, slippery, or have steep uphill or downhill
slopes.

ACC Operation At Stop
If the ACC system brings your vehicle to a standstill while
following a target vehicle, if the target vehicle starts
moving within two seconds of your vehicle coming to a
standstill, your vehicle will resume motion without the
need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the ACC
with Stop system will cancel and the brakes will release. A
cancel message will display on the instrument cluster
display and produce a warning chime. Driver intervention
will be required at this moment.
While ACC with Stop is holding your vehicle at a stand-
still, if the driver seatbelt is unbuckled or the driver door is
opened, the ACC with Stop system will cancel and the
brakes will release. A cancel message will display on the
instrument cluster display and produce a warning chime.
Driver intervention will be required at this moment.

WARNING!(Continued)
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.

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.

WARNING!(Continued)
continue to pay attention to your surroundings. Fail-
ure to do so can result in serious injury or death.
•
Before using the ParkSense Active 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
obstacles because the hitch ball will be much closer to
the obstacle than the rear fascia when the loudspeaker
sounds the continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly, depend-
ing on its size and shape, giving a false indication that
an obstacle is behind the vehicle.

WARNING!
Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles, obstruc-
tions, or blind spots before backing up. You are re-
sponsible for the safety of your surroundings and must
continue to pay attention while backing up. Failure to
do so can result in serious injury or death.
