Step 2: Perform Required Maintenance

If you have not yet performed the maintenance, use the following steps:

Oil Change:
- Lift the vehicle using jack stands.
- Remove the drain plug using a socket set and allow the old oil to drain into an oil pan.
- Replace the oil filter using an oil filter wrench.
- Install the new oil filter and tighten it according to specifications.
- Replace the drain plug and torque it to the manufacturer's specification.
- Add the new oil through the oil fill cap using a funnel, checking the level with the dipstick.
Air Filter Replacement (if necessary):
- Locate the air filter housing, usually near the engine cover.
- Release the clips or screws holding the housing.
- Remove the old air filter and replace it with a new one.
- Reassemble the housing.
Tire Check:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate or deflate tires as needed to match the recommended PSI (found in the owner’s manual or door jamb).
Fluid Checks:
- Check the coolant, brake fluid, transmission fluid, and power steering fluid levels and top off as necessary.
Brake Inspection (optional):
- Inspect brake pads and rotors for wear and replace if necessary.
