Nudge mode (or Nudging Service) is an elevator mode which when the door is held past a certain time, usually 30 seconds, and "nudges" closed while a buzzer, tone, or voice sounds, signaling to stand clear of the door.
Nudge mode actions prefix[]
Different elevator companies (with proprietary controllers) and even non-proprietary elevator component companies' controllers have different nudge mode prefix. During nudge mode, the call button on the floor where the elevator is nudging is disabled (simplex) or assign the other available elevators (in a group), and will not open up the doors. On some elevators holding the door open button from the elevator will bypass nudge mode.
- Buzzing and the doors force to close.
- Same method with floor indicators flashing.
- Same method works when the car call or hall call registered.
- Same method with door close buttons light up.
- Just plays a sound, and does not force close the doors[1].
- Same method with door close buttons light up.
- Same method but door close buttons does not light up.
- Mute when the doors are closing and resound when the doors reopen.
- All the registered car calls and hall calls cancelled (Can register after cancellation).
- Put the elevator out of service.
- Plays the chime repeatedly and door does not force close.
- Plays the announcement repeatedly when the door sensors triggered in a specific time and door does not force close.

Trivia[]
- Nudge mode cannot bypass the loading sensor, which means it doesn't work when the elevator is overloaded.
- Many people get nudge mode confused with a door malfunction. The difference though is that a door malfunction is:
- when the elevator car starts moving with the doors open (also known as unintended car movement).
- when the doors behave improperly (fail to close or open)
- Nudge mode activates frequently if a crowded shopping mall or metro stations with a lot of people using the one and only passenger elevator.
- Elevators in parking garages/car parks tend to have a faster nudge timer.
- The timing of nudging service may be reduced automatically depends on the loading of the lift car.
