Why does the clock stay on after you turn the engine off in your rav 4?

The clock in your RAV4 stays on after turning off the engine because it is powered by a constant electrical source from the vehicle's battery. This allows the clock to maintain the correct time even when the ignition is off. Additionally, it ensures that other settings, like the radio or interior lights, can also remain functional for a short period after the engine is turned off. This feature is designed for user convenience.
