While in Sentry Mode, Model Y may shift through three
states as a response to its surroundings-Standby, Alert,
and Alarm:
Standby. Model Y is automatically "on standby" when
you activate Sentry Mode. The cameras constantly
monitor the surrounding area for possible security
threats.
Alert.
When you finish driving, simply exit the vehicle. When
you leave Model Y with your phone key and key fob, it
powers off automatically, turning off the instrument
panel and touchscreen.
Model Y also powers off automatically after being in
Park for 30 minutes, even if you are sitting in the drive
