A vehicle retractable step assembly includes a support member, a support arm, a step member and a restricting assembly. The support member is configured to attach to a vehicle body structure. The support arm has a first end and a second end. The first end is supported to the support member for pivoting movement with respect to the support member. The step member is attached to the second end of the support arm for pivotal movement relative to the second end of the support arm between a retracted orientation where the step member is located adjacent to the support member and an extended orientation where the step member is spaced apart from the support member. The restricting assembly is releasably attached to the support member and positioned to prevent pivoting movement of the support arm relative to the support member.
