When you set the ISO to 400, it will stay at 400 whether indoor or outdoors.
To let the camera to change the ISO, you need to set the ISO to Auto.

Hi,

You can try to use P mode (is full auto also, but you can modify ISO settings). Auto ISO, on Canon, keep iso settings to 400 on 400D and 40D without any custom function modifications. Check your manual to see what custom function must be activated to use 100-400 ISO on Auto ISO setting.
