Hi there. The radio code for your car should be integrated with the instrument cluster, so you shouldn't need to enter the code when you disconnect the battery (only if you swap the cluster or the radio).

I prefer to plug the battery tender onto the battery leads themselves, but plugging it into the cigarette lighter shouldn't do any permanent harm.

The front trunk lamp should go off after about two hours of staying on (with the trunk open). There's a computer that times this and then shuts down the accessories so that your battery won't run out.

Hope this helps,

Wayne
