Resume Control
WARNING: This page is about a different car, the 2008 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
After the cruise control mode is cancelled by any of the cancel switches, the mode can be resumed and controlled at the set speed by operating the cruise control switch in the + RES direction, providing that the vehicle speed has not dropped below the low speed limit [Approx. 40 km/h (25 mph)].
The mode cannot be resumed if the vehicle speed once drops below the low speed limit, because the speed in the memory is cleared.
