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.
