Active Park Assist Troubleshooting Possible Cause
Symptom
The system is unable to detect a vehicle, curb or object
to park next to, or in-between. This could occur because
of sensors not operating correctly, not enough room
for your vehicle, or the traction control is off.
The system does not correctly
operate.
You may have switched traction control off.
The system does not search for
a parking space.
The transmission is in reverse (R). Your vehicle must
be moving forward to be able to detect a parking space.
There could be blockage on the sensors. For example,
snow, ice or large accumulations of dirt. Blocked
sensors can affect how the system functions.
The system does not offer a
parking space.
The sensors in the front or rear bumper could be
damaged.
There is not enough room in the parking space for your
vehicle to safely park.
There is not enough space for the parking maneuver on
the opposite side of the parking space.
The parking space is more than 5 ft (1.5 m) or less than
2 ft (0.5 m) away.

HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to adjust
the speed of your vehicle to maintain a set
gap from the vehicle in front of you in the
same lane while following it to a complete
stop. You can also engage the system to
follow a vehicle in front of you and adjust
set speed while stopped.
WHAT IS ADAPTIVE CRUISE
CONTROL WITH LANE
CENTERING
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the lane by applying
continuous assistance steering torque
input toward the lane center on highways.
Note:
The adaptive cruise control gap
setting operates normally.
WHAT IS INTELLIGENT
ADAPTIVE CRUISE CONTROL
Intelligent adaptive cruise control
combines speed sign recognition with
adaptive cruise control to adjust the cruise
set speed to the speed limit detected by
the speed sign recognition system. For
example, if the speed sign recognition
system detects a 50 mph (80 km/h)
speed limit, the cruise set speed is updated
to
50 mph (80 km/h).
Note: The adaptive cruise control gap
setting operates normally. ADAPTIVE CRUISE CONTROL
