Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the cruise
control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or more,
press the +RES button on your steering wheel.
The vehicle will go back to the previous set speed
and stay there.
