WARNING: This page is about a different car, the 2002 Lexus GS 430 and 2002 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
When the vehicle speed is within the low speed limit (approximately 25 mph) if the cruise control is cancelled, use of the RES/ACC switch accelerates the vehicle to the speed level used before canceling the cruise control.
