GMC Terrain: Driver Assistance Systems / Rear Cross Traffic Alert (RCTA)

If equipped, when the vehicle is shifted into R (Reverse), RCTA displays a red warning triangle with a left or right pointing arrow to warn of traffic coming from the left or right. This system detects objects coming from up to 20m (65 ft) from the left or right side of the vehicle.
