Hello Nate, your auxiliary battery is on the left side underdash. You can unbolt the bracket by removing the left dash side cover where the fuse box may be at and then you access the battery from under the dash. They are plug and play so when you replace it the warning will subside. Let me know if you need more info. Lou P.
