If the power tonneau does not operate, recalibrate the top by pressing the open/close buttons together for 10 seconds. Refer to Pickup Box Cover Package Installation, Calibration Procedure section in SI. If the top fails to calibrate then crawl inside the bed to the front and push in the release lever on the Tonneau motor unit. (Passenger side of vehicle white color -glow in the dark.) Top can then be opened manually. Once open, pull the lever back out to re-engage the motor. from: https://static.nhtsa.gov/odi/tsbs/2022/MC-10210894-0001.pdf
