SummaryWhen the power windows are operated many times without being fully closed, small errors of the window position sensor may accumulate and cause improper operation of the jam-safe function. To reduce the risk of this occurrence, the AUTO function is disabled if the power window is operated 10 consecutive times without being fully closed (turning the ignition OFF and then ON does not reset the counting). If the power window is fully closed before the 10th time, the counting restarts and the AUTO function is not deactivated.
