POWER DEPLOYABLE RUNNING BOARDS (IF EQUIPPED)
WARNING: In extreme climates, excessive ice buildup may
occur, causing the running boards not to deploy. Be sure that the
running boards have deployed, and have finished moving before
attempting to step on them. The running boards will resume normal
function once the blockage is cleared.
WARNING: Turn off the running boards before jacking or placing
any object under the vehicle. Never place your hand between the
extended running board and the vehicle. A moving running board may
cause injury.
Note: Do not use the running boards, front and rear hinge assemblies,
running board motors, or the running board under body mounts to lift
the vehicle when jacking. Always use proper jacking points.
Note: The running boards may operate slower in cooler temperatures.
Debris such as mud, dirt and salt may become trapped in the running
board mechanism, possibly leading to unwanted noise. If this occurs,
manually set the running boards to the deployed position and flush the
system (in particular the front and rear hinge arms) with a high-pressure
car wash wand.

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 after a two second
delay when the doors are closed.
Load Carrying
The running boards automatically
move when the doors are opened to
assist entering and exiting the
vehicle.
