Step by step

10 steps
  1. Open the hood and locate the battery on the left side of the engine bay (driver's side).
  2. Disconnect the negative terminal (black, -): loosen the 10 mm nut, remove the terminal, and move the cable aside.
  3. Disconnect the positive terminal (red, +): loosen the 10 mm nut and remove the terminal.
  4. Remove the hold-down clamp (usually a plastic bracket on top) by unscrewing the 10 mm bolt.
  5. Lift the old battery straight up (it weighs about 15-18 kg, so hold it by the side handles).
  6. Lower the new battery into the tray and orient the terminals correctly (+ on the left, - on the right).
  7. Install the hold-down clamp and tighten the bolt.
  8. Connect the positive terminal and tighten the nut (do not overtighten: 5-7 N·m (3.7-5.2 lb-ft)).
  9. Connect the negative terminal and tighten the nut.
  10. Close the hood and wait 1-2 minutes for the vehicle's electrical system to stabilize.

Common mistakes and warnings

  • After installing the new battery, the infotainment display may ask you to re-enter the audio system PIN code (listed in the owner's documentation). If the car sat for a long time without a battery, reset the electronics: open the driver's door and press the START button 3-4 times without pressing the brake pedal (do not start the engine). Disposal: Take the old battery to a recycling center or an auto parts store. Many stores offer a core credit toward a new battery.
