Hi, 2 days ago when I'm about to go at work just seen a red light warning sign in my Daihatsu charade car.I was confused what does it means with the red light warning sign.can you help ?

I would check Oil and water first.

Red has always been STOP.
Your particular light could also be for the braking or charging system.
If it comes on again, you need to get this diagnosed.

I agree with the Brake Light:
