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
Keep people and objects clear of both boards before operating the switch or a door.
- 02
Leave the running-board switch in neutral for automatic mode; the board on that side deploys when a door opens and retracts after it closes.
- 03
Use the deploy or stow switch position when both boards need to be commanded directly, then return it to neutral for automatic operation.
- 04
Turn the system off before cleaning the boards, jacking the vehicle or placing anything underneath it.
Important limits
- The boards automatically stow at approximately 3 mph and will not deploy again until speed drops below that threshold.
- Jam protection cannot prevent every injury; wait until a board is fully deployed before stepping on it.
Quick checks.
- ✓If a board stops after contacting an obstacle three times, clear the obstruction and open and close the same-side door or operate the switch again.
- ✓Remove snow, mud or ice if a board will not deploy or retract; a persistent malfunction message requires Lexus dealer inspection.
