Tesla have widened their voice command capabilities and are trying to introduce natural language capabilities. As a result many variations of a phrase can execute the same command.
Before we list the typical commands, it's worth noting that the Tesla voice command system can be extremely temperamental. Some users report it not understanding them at all, some think it only responds to an American accent, some seem to think it is just hit and miss whether it understands what you are saying. More frustratingly is the car sometimes displays a perfectly valid command on the screen and then fails to understand it one time, but does another. Whether the voice commands are processed locally or remotely from the car and whether communication issues cause the problem, or just the version of software you are running in the car causes the difference, it is hard to tell, but variability in performance is common.
To initiate a voice command on a Model S and Model X, simply tap the voice button on the upper right side of the steering wheel. For Model 3 and Y owners, press the right scroll button on your steering wheel or access through the touch screen. One of the common mistakes is not waiting until you hear the tone before speaking your command.
While we have listed a lot of commands, there is a clear pattern with them and you just need to know the name Tesla want you to use for the object e.g. windscreen or windshield wipers. You are not going to remember all of the commands, but familiarising yourself with the style of command format will make things easier.
