Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Stop the vehicle and make sure people, curbs and other objects are clear of both running-board paths.
- 02
In MBUX open Settings > Vehicle > Side Running Board.
- 03
Select Extend or Retract for manual positioning, such as before cleaning.
- 04
To make the board extend on the side of an opened door, activate Automatic Extension.
- 05
After a manual extension with the doors closed, drive above 2.5 mph (4 km/h) to restore automatic behavior.
Important limits
- The running boards move only while the vehicle is stationary.
- Extension increases vehicle width and retraction creates a pinch zone at the side skirt.
- The boards retract automatically for an off-road program, car wash mode, automatic mirror folding or speed above 2.5 mph.
Quick checks.
- ✓If a board does not move, stop the vehicle and check the path and instrument-cluster message.
- ✓If manual extension seems to disable automatic retraction, drive above 2.5 mph in a clear area to reactivate automatic mode.
- ✓Do not force a board obstructed by ice, mud or a curb; clear the obstruction first.
