To replace the battery in a 2022 Subaru Crosstrek, first locate the battery in the engine compartment, then use a 10mm wrench to disconnect the negative (black) terminal, followed by the positive (red) terminal, and then remove the battery hold-down bracket. Install the new battery by reversing the steps, ensuring the positive terminal is connected first, and secure the hold-down bracket.
