These instructions apply to the Subaru XV Mk1 (GP) 2012-2017.

The 12-volt battery on the first-generation Subaru XV (GP, 2012–2017) sits in the engine compartment. Disconnecting it is straightforward, but the boxer-engined XV relearns several settings afterwards, so note your audio security code first and be ready to re-initialise the windows and sunroof.
How to disconnect and reconnect the XV battery
- Note the radio/navigation security code and your preset stations, and have them to hand for later.
- Switch off the ignition and all electrical loads, and close the doors and tailgate.
- Open the bonnet and locate the battery in the engine compartment.
- Slacken and remove the negative (−) terminal first, then the positive (+) terminal. Tuck the leads aside so they cannot spring back onto the posts.
- Carry out your work. When refitting, connect the positive (+) terminal first, then the negative (−), and tighten both clamps securely.
- Switch the ignition on and re-enter the audio code, then reset the clock and preset stations.
- Re-initialise the power windows so the one-touch/auto function works again, and re-initialise the electric sunroof if one is fitted.
- Drive the car so the indirect tyre-pressure monitor relearns its reference.
Always remove the negative lead first and reconnect it last — it keeps the spanner from shorting a live terminal to the bodywork.
Frequently Asked Questions
Where is the battery on a Subaru XV (GP)?
In the engine compartment, accessed by opening the bonnet. The GP does not carry its 12-volt battery in the boot.
What do I lose when I disconnect the battery?
The clock, radio presets and any stored audio code, plus the learned settings for the power windows, the sunroof and the indirect tyre-pressure monitor. All of these are restored with the quick re-initialisation steps above.
Do I need to reset anything after reconnecting?
Yes — re-enter the audio code, reset the windows and sunroof, and drive the car to relearn the tyre-pressure reference. The engine will also smooth out its idle again over the first few minutes of running.
If a warning light stays on after reconnecting, read the stored code on autodtcs.com before clearing it.
