Could I drain the battery if I leave on the dome light?

The Prius C will turn off the interior lights after 20 minutes if you have turned off the car.

My wife took our Prius C and left the main head lights on at night and I noticed in the morning that the switch was left on, but luckly the lights had turned off by them self. The car started up fine too. Now, you do get a biping sound if you turn off the car and leave the head light on, but she didn't noticed that

 

^^ Are you sure that it beeps if the headlights are left on? That would be a step backwards. It should be a silent Auto-Off somewhere between 0 and 90 seconds after shutdown, like my regular Prius and even my late 20th Century non-hybrid.

 

It absolutely beeps if you've left the headlights on when you open the door to leave the car. The lack of auto off/on headlights is one of the major nitpicks people have had with the c. But, according to rioe's story, they apparently do turn off after some amount of time? It must be mentioned in the manual somewhere.

Battery-saving function
In the following conditions, the remaining lights will go off automatically after
20 minutes in order to prevent the vehicle battery from being discharged:
●The headlights and/or tail lights are on.
●The engine switch is turned to the “ACC” or “LOCK” position (vehicles
without a smart key system) or the “POWER” switch is turned to ACCES-
SORY mode or turned off (vehicles with a smart key system).
This function will be canceled in any of the following situations:
●When the engine switch is turned to the “ON” position (vehicles without a
smart key system) or the “POWER” switch is turned to ON mode (vehi-
cles with a smart key system).
●When the light switch is operated.
●When the door is opened or closed.

 

Wonderful, thank you Glad to have peace of mind that I won't drain the battery if I leave the headlights on.

 

PC turns everything of either in 15 or 20 mins. I was doing something in the car sometime ago, and I was listening my radio in the meantime. I didn't notice the exact time frame (it felt like 15-20 mins), but the message popped up in the main information screen saying the the power is turned off in order to save the battery.
