Check that all doors activate the Power Step and the LED Lights work when doors open and
close. Reinstall any remaining trim panels. Due to Variances in the sheet metal a shim
kit is provided if Steps do not retract properly. See Step 3 for shim placement.
CORRECT OPERATION OF LIGHTS: All four lamps will illuminate upon opening any door of vehicle. Lamps
will stay on until restowing of both Power Steps or until 5 minutes has expired with the doors open. When the
lights timeout after 5 minutes, they can be reillumintated by closing and opening any door of vehicle.
FINAL SYSTEM CHECK
Check that all doors activate the PowerStep and the LED lights work when doors open and close.
NORMAL OPERATION: When the doors open, PowerStep automatically deploys from under the vehicle.
When the doors are closed, PowerStep will automatically return to the stowed/retracted position. Note that
there is a 2-second delay before the PowerStep returns to the stowed/retracted position.

Automatic power deploy:
The running boards will extend down and out when the doors are opened.
Automatic power stow:
The running boards will return to the stowed position when the doors are closed. There will be a 2-second
delay before the running boards move to the stowed position.
Automatic stop:
If an object is in the way of the moving running board, the running board will automatically stop.
To reset, clear any obstruction, then simply open and close the door to resume normal operation.
Manually set in the deployed (OUT) position for access to the roof:
your foot while at the same time closing the door. To resume normal operation, open and close the door.
Maintenance: In adverse conditions, debris such as mud, dirt, and salt may become trappedin the running
board mechanism, possibly leading to unwanted noise. If this occurs, manually set the running boards to
Avoid spraying the motors directly. After washing, apply silicone spray lubricant to the hinge pivot pins.
