Order of inspection
P2096 Post Catalyst Fuel Trim System Too Lean (Bank 1) Medium
The P2096 code means the oxygen sensor located after the catalytic converter reports a mixture that is too lean, and the fine correction the computer applies has run out of range. The most frequent cause is not an actually lean mixture but an exhaust leak that lets air in between the engine and that sensor. You can drive with caution, but an exhaust leak can let fumes into the cabin.
