Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and the
vehicle ahead is stopped in your lane. Always be attentive
and ready to apply the brakes if necessary.
General Information
This vehicle has systems that operate on radio frequency
that comply with Part 15 of the Federal Communications
Commission (FCC) rules and with Industry Canada Stan-
dards RSS- GEN/210/220/310.Operation is subject to the following two conditions:
1. The device may not cause harmful interference.
2. The device must accept any interference received, in-
cluding interference that may cause undesired operation
of the device.
Changes or modifications to any of these systems by other
than an authorized service facility could void authorization
to use this equipment.
Normal (Fixed Speed) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Cruise Control mode is available for cruising
at fixed speeds. The Normal (Fixed Speed) Cruise Control
mode is designed to maintain a set cruising speed without
requiring the driver to operate the accelerator. Cruise
Control can only be operated if the vehicle speed is above
20 mph (32 km/h).
To change between the different control modes, push the
Adaptive Cruise Control (ACC) on/off button which turns
the ACC and the Normal (Fixed Speed) Cruise Control off.
Pushing the Normal (Fixed Speed) Cruise Control on/off
button will result in turning on (changing to) the Normal
(Fixed Speed) Cruise Control mode.
Stationary Object And Stationary Vehicle Example
316 STARTING AND OPERATING

•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

When an available parking space has been found, and the
vehicle is not in position, you will be instructed to move
forward to position the vehicle for a parallel parking
sequence.Once the vehicle is in position, you will be instructed to
stop the vehicle’s movement and remove your hands from
the steering wheel.
Space Found — Keep Moving Forward

STARTING AND OPERATING 343

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. Once the vehicle is in a standstill condition, the driver will
be instructed to place the gear selector into the DRIVE
position.

352 STARTING AND OPERATING

•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

LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at speeds above
37 mph (60 km/h) and below 112 mph (180 km/h). The
LaneSense system uses a forward looking camera to detect
lane markings and measure vehicle position within the
lane boundaries.
When both lane markings are detected and the driver
unintentionally drifts out of the lane (no turn signal
applied), the LaneSense system provides a haptic warning
in the form of torque applied to the steering wheel to
prompt the driver to remain within the lane boundaries. If
the driver continues to unintentionally drift out of the lane,
