After every few km, the IMA indicator lights up. What does it mean?

What is your question?

When I drive my car, after around 3 - 5 km, its front panel starts indicating IMA (the indicator IMA lights up). It does not extinguish till I stop and turn off the engine. When I restart, IMA sign is gone, but reappears after 3-5 km again.

What makes this problem better or worse?

Actually nothing. It keeps running without any issue

How long has your 2007 Honda Civic had this problem?

a couple of weeks
