General Motors Rear Park Assist Technology
Rear Park Assist is a General Motors active safety technology that helps the driver park their vehicle when in reverse and avoid crashing into nearby objects.
How It Works
Rear Park Assist is activated when the vehicle:
- Is in Reverse gear and
- Is traveling at speeds below 5 mph (8 km/h)
The system provides “distance-to-object” and object location alerts to help the driver park and avoid crashing into nearby objects during low-speed backing by using 4 ultrasonic sensors mounted on the rear bumper that have a range of up to 8 feet (2.4 meters). The sensors are capable of detecting objects within a zone of 10 inches (25 cm) off ground and below bumper level.
The vehicle’s instrument cluster shows locations for rear-detected objects close to the vehicle. As the vehicle gets closer to the object:
- More bars illuminate, with bar color changing from yellow to amber to red, and
- The interval between rear object detection beeps becomes shorter
When a vehicle is equipped with Rear Park Assist as well as with the Rear Vision Camera, a warning triangle on the camera screen shows where the nearest object has been detected. As the object gets closer, this triangle changes from amber to red and increases in size.
Turning The System On & Off
Rear Park Assist can be toggled on or off using:
- A hard switch (button) with an LED indicator, with a lit LED indicator indicating an ON setting, or
- An option in the vehicle setting menu
