Power Assist Steps - GMC 2009 Yukon XL Owner's Manual

Power Assist Steps

Your vehicle may have power assist steps.
The power assist steps automatically extend from
beneath the vehicle on the side in which the door has
been opened. Once the door is closed, the assist steps
automatically move back under the vehicle after a
brief delay. The vehicle must not be moving for the
assist steps to extend or retract.
The assist steps cannot be disabled in the extended
position.
The switch used to disable
the power assist steps is
located on the center
console below the climate
control system.
