Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical issues during maintenance (if applicable).
2. Change Engine Oil and Filter

  1. Drain Old Oil

    • Place an oil catch pan under the oil pan.
    • Remove the oil drain plug using a socket set and allow the oil to completely drain.
    • Replace the drain plug and torque to manufacturer's specifications.

  2. Replace Oil Filter

    • Locate the oil filter; use an oil filter wrench to remove it.
    • Lubricate the rubber O-ring on the new oil filter with clean oil.
    • Install the new oil filter by hand until snug, then tighten according to the manufacturer's instructions.

  3. Add New Oil

    • Pour the recommended type and amount of engine oil into the engine through the oil filler cap.
    • Start the engine and let it run for a minute, then check for leaks around the oil filter and drain plug.
3. Reset Maintenance Light
  1. Reset Procedure
    • Turn the ignition to the "ON" position without starting the engine.
    • Press the gas pedal three times within 10 seconds.
