Driving and Operating Warning (Continued) speed backing maneuvers, or where there could be cross traffic. Failure to use proper care before backing may result in injury, death, or vehicle damage. Always check behind and around the vehicle before backing. 9-49 1. View Displayed by the Camera 2. Corners of the Rear Bumper Displayed images may be farther or closer than they appear. The area displayed is limited and objects that are close to either corner of the bumper or under the bumper do not display. A warning triangle may display on the RVC screen to show where the Ultrasonic Rear Parking Assist (URPA) has detected an object. This triangle changes from amber to red and increases in size the closer the object. On vehicles with the Rear Cross Traffic Alert (RCTA), a triangle with an arrow may also display on the RVC screen to warn of traffic coming from either direction when backing. This system detects objects coming from up to 20 m (66 ft) from the left or right side behind the vehicle. When an object is detected, either three beeps sound from the left or right side or three Safety Alert Seat pulses occur on the left or right side, depending on the direction of the detected vehicle. Use caution while backing up when towing a trailer, as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. With URPA, as the vehicle backs up at speeds of less than 8 km/h (5 mph), the sensors on the rear bumper detect objects up to 2.5 m (8 ft) behind the vehicle that are within a zone 25 cm (10 in) high off the ground and below bumper level. 1.
