Car explodes instantly

Hi I am having trouble with a thing happening with me on eu4. I have made a exploding car using M5 VFX Vol2 Fire and flames pack but every time I press play the car explodes instantly. is there a way for me to set a trigger box so the event happens when I get close to it?

More info needed. What is the setup for your explosion? Is it a particle component system? Some screenshots to better understand.

how do I take a screenshot?

press ‘‘print sreen’’ than open paint and press ‘‘ctrl v’’
