Why does the check engine light in my SC400 turn on when I start my car?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your SC400 firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Is it okay to put water in my Lexus SC400 radiator?

However, if you need to continue driving your SC400 when you’re out of coolant, having water in the coolant reservoir is better than nothing.
