Rear Cross-traffic Collision-Avoidance Assist (RCCA) is designed to warn the driver under certain conditions. It may activate the Electronic Stability Control (ESC) and temporarily apply braking if it detects cross traffic approaching the vehicle when the vehicle is in reverse. 

If the RCCA rear-corner radar sensors detect approaching vehicles from the rear left or rear right side of the vehicle , RCCA will sound a warning, the warning indicators on the outside rearview mirror will illuminate and a message will appear on the Instrument Cluster and the Infotainment System screen. If RCCA detects that the collision risk has increased, RCCA automatically applies the brakes to reduce your speed, potentially helping to minimize the effects of a possible collision. 

RCCA is designed to operate under the following conditions:

• When the gear shift is in Reverse
• When the vehicle is moving slower than 5 mph

• To turn RCCA on: Press the SETUP key on the Infotainment System. Press VEHICLE to enter VEHICLE SETTINGS. Select DRIVER ASSISTANCE, PARKING SAFETY, and then REAR CROSS TRAFFIC SAFETY 
• Warning Methods: To adjust the Warning Volume settings, go to VEHICLE SETTINGS, DRIVER ASSISTANCE and under WARNING METHODS, you can adjust the Warning Volume, activate Haptic Warning
