Reverse Parking Collision-Avoidance
Assist is a supplemental system that can
warn the driver or apply braking force
to reduce the possibility of collision
with pedestrians when the vehicle is
reversing.
WARNING
• Always look around your vehicle to
make sure there are no objects or
pedestrian before moving the vehicle
in any direction to prevent a collision.
• Do not solely rely on Reverse Parking
Collision-Avoidance Assist system.
The system might not assist the
driver leading to pedestrian injury or
vehicle damage.
• Be aware that some objects may
not be visible on the screen or be
detected by the rear ultrasonic
sensors, due to the objects’ distance,
size or material, all of which can limit
the effectiveness of the sensors.
