Resuming a Set Speed
If cruise control is set at a desired speed and the brakes are applied, this shuts off the cruise control.
However, it does not need to be reset.
Once your vehicle reaches a speed of about 40 km/h (25 mph) or more, press the +RES button on the steering wheel. The vehicle goes back to the previously selected speed and stays there.
