Tesla S Owner's Manual page 49

1. If you turn on DOME lights, all interior dome (map) lights turn on when you unlock Model S,
open a door upon exiting, or shift into P (Park). They turn off after 60 seconds, when you lock
Model S, or when you shift into a driving gear. If set to AUTO, dome lights turn on only when
little or no light is detected.
You can also manually turn an individual dome light on or off by pressing its lens. If you
manually turn a dome light on, it turns off when Model S powers off. If Model S was already
powered off when you manually turned the light on, it turns off after 60 minutes.
2. If you turn on AMBIENT lights, the lights on the door armrests turn on whenever the
headlights are on.
3. If you turn on AUTO HIGH BEAM, high beam headlights turn on and off automatically based
on whether or not light is detected in front of Model S (see
51). This feature is available only if Model S is equipped with the optional Autopilot Tech
Package.
4. DRL (Daytime Running Lights) operate only when driving with the headlights off. In
jurisdictions where required by law (Canada), daytime running lights can not be turned off.
5. If Model S is equipped with optional front fog lights, touch to turn them on or off.
The fog lights operate only when low beam headlights are on. Whenever headlights are
turned off, fog lights also turn off.
