WARNING: This page is about a different car, the 2002 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
Resetting To A Faster Speed
Push the lever up in the "RES/ACC" direction and hold it. See Figure. Release the lever when the desired speed is attained. while the lever is held upward, the vehicle will gradually gain speed.
However, a faster way to reset is to accelerate the vehicle then push the lever down in the "SET/COAST" direction. See Figure.
Resuming The Preset Speed
If the preset speed is cancelled by pulling the control lever, by depressing the brake pedal, or by pushing the lever up in the "RES/ACC" direction will restore the speed set prior to cancellation. See Figure.
However, once the vehicle speed falls below about 25 mph (40 km/h), the preset speed will not be resumed.
