Great question! And you’re in luck, because all configurations of the 2012 Chevy Malibu come with Bluetooth connectivity.
To pair your phone with your Malibu’s Bluetooth, make sure your phone’s Bluetooth is enabled in “Settings”. Next, press and hold the speech button on the right-hand side of your steering wheel. Your system will say “ready,” after which you respond “pair”—follow the instructions on your screen from there, and you’ll be connected!
