Solution

1. Regular Oil Change

Sub-steps:
1. Gather the required materials: new oil filter, engine oil (SAE 0W-20), oil catch pan, and a wrench.
2. Warm up the engine slightly, then turn it off.
3. Place the oil catch pan under the oil pan and remove the drain plug to let the old oil drain completely.
4. Replace the drain plug and tighten it to the manufacturer’s torque specifications (usually around 30 ft-lbs).
5. Remove the old oil filter using an oil filter wrench and install the new filter.
6. Fill the engine with new oil using a funnel and check the oil level with the dipstick.

2. Tire Maintenance

Sub-steps:
1. Check tire pressure monthly using a tire pressure gauge and inflate to the recommended PSI.
2. Rotate tires every 5,000 to 7,500 miles to promote even wear.
3. Inspect tires for signs of damage or wear, replacing them when tread depth is below 2/32 of an inch.

3. Brake Inspection

Sub-steps:
1. Inspect brake pads and rotors for wear every 10,000 miles.
2. Replace brake pads when they are worn down to 3mm.
3. Check the brake fluid level and top up as necessary with DOT 3 or DOT 4 fluid.

4. Fluid Checks

Sub-steps:
1. Check engine coolant level and top up with Toyota-approved coolant if necessary.
2. Inspect transmission fluid every 30,000 miles; replace if it appears dirty or burnt.
3. Examine power steering fluid and brake fluid levels regularly, topping up as needed.

5. Battery Maintenance

Sub-steps:
1. Inspect battery terminals for corrosion and clean them with a mixture of baking soda and water.
2. Test battery voltage with a multimeter; replace the battery if voltage is below 12.4 volts.
3. Ensure the battery is securely mounted and check connections for tightness.
