Operating conditions
Reverse Parking Collision-Avoidance
Assist system enters the ready status,
when ‘Active Assist’ or ‘Warning Only’ is
selected in the AVN system screen and
the following conditions are satisfied:
• The trunk is closed
• The shift lever is in R (Reverse)
• Vehicle speed is below 6 mph (10
km/h)
• System components such as the rear
view camera and the rear ultrasonic

Reverse Parking Distance Warning
system assists the driver during reverse
movement of the vehicle by chiming if an
object is sensed within the distance of 48
in (120 cm) behind the vehicle.
This system is a supplemental system
that senses objects within the range and
location of the sensors, it cannot detect
objects in other areas where sensors are
not installed.
WARNING
• ALWAYS look around your vehicle to
make sure there are not any objects
or obstacles before moving the
vehicle in any direction to prevent a
collision.
• Always pay close attention when the
vehicle is driven close to objects,
particularly pedestrians, and
especially children.
• Be aware that some objects may
not be visible on the screen or be
detected by the sensors, due to the
objects distance, size or material, all
of which can limit the effectiveness
of the sensor.
Operation of Reverse Parking
Distance Warning System
Operating condition
• This system will activate when
backing up with the ignition switch in
the ON position. However, if vehicle
speed exceeds 3 mph (5 km/h), the
system may not detect objects.
• If vehicle speed exceeds 6 mph (10
km/h), the system will not warn you
even though objects are detected.
• When more than two objects are
sensed at the same time, the closest

Reverse Parking Distance
Warning System Precautions
• Reverse Parking Distance Warning
system may not sound consistently
depending on the speed and shapes
of the objects detected.
• Reverse Parking Distance Warning
system may malfunction if the vehicle
bumper height or sensor installation
has been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
• The sensor may not recognize objects
less than 12 in (30 cm) from the
sensor, or it may sense an incorrect
distance. Use caution.
• When the sensor is frozen or stained
with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
• Do not push, scratch or strike the
sensor with any hard objects that
could damage the surface of the
sensor. Sensor damage could occur.
• Do not spray the sensors or its
surrounding area directly with a high
pressure washer. Shock applied from
