    Another question: my friend is trying to reset the maintenence light on her 2014 after she changed the oil. I've tried what the book says, but it doesn't work. I've also tried online, and 2 different things didn't work either.

    Not sure which battery maintainer you bought, but if it is the Noco Genius, the battery will recharge automatically, on and off every few days, as long as it is connected.

    Ask it on the Gen 3 forum.

    Back to my question about the odometer and temperature reading not changing since the dead battery. Is there something I need to do?

    But it says to not use the trikle charge inside the car. I was hoping to put it next to the battery in the car and plug the charger into a backup battery. That sounds like it won't be safe. Do I have to remove the battery from the car?

    Do I have to take it back to the dealer to reset them or will it happen eventually?

    Again, if it is the Noco Genius, it could be left powered on and connected to the car indefinitely. No idea what you bought.

    Those things never need a reset and shouldn’t be affected by a 12-V battery disconnect. If there is really a malfunction, no idea what the problem is.

    Don’t keep the hatch open, though, as the light bulb will burn out. Those miniature tungsten bulbs have a life of only a few hundred hours. Use the 12 V service connector under the hood instead.

    tungsten? lol. This is a Gen5!

    I have a NOCO1 in the trunk, attached to the battery, just in case, or did I say that already?
    My plan is to hook it up to a thin, flat extension cord. I do believe the weatherstripping will be okay when the hatch is closed.
    The battery has a vent tube to the outside.

    Giant leap in technology with the trunk light having been updated from tungsten to LED from Gen 4 to Gen 5! ;)
