FORD 2012 F-150 Raptor v.1 - Manual (Page 126)

To deploy the box side step, with your foot, push down on the button.
The step will automatically extend out from the stowed position.
Note: The box side steps may operate slower in cooler temperatures. In
adverse conditions, debris such as mud, dirt, snow, ice, and salt may
become trapped in the box side step mechanism, possibly causing the
box side step to not deploy automatically after pressing the button. If
this occurs, ensure that the button is pressed down, carefully manually
pull out the box side step, wash off the debris with a high-pressure car
wash wand, and re-stow the step.
To stow the box side step, with your foot, push the box side step under
the truck until fully latched. Do not push on the button while stowing
the box side step.
Note: Do not use the box side steps to lift the vehicle when jacking.
Utilize proper jacking points. Refer to Changing the tires in the
Roadside Emergencies chapter.
