Enable/disable:
To enable/disable the power running board feature, refer to Message
center in the Instrument Cluster chapter.
• When this feature is disabled (OFF), the running boards will move to
the stowed position regardless of the position of the doors.
• When this feature is enabled (AUTO), the running boards will move
back to the correct positions based off of the door positions.
Bounce-back:
• If an object is in the way of the moving running board, the running
board will automatically bounce back in the reverse direction and
move to the end of travel.
Note: The running boards may operate slower in cooler temperatures. In
adverse conditions, 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.
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. Please utilize proper jacking points. Refer to
Changing the tires in the Roadside Emergencies chapter.
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. Note: 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.
