Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Gather safety equipment, including gloves and safety glasses.

2. Change Engine Oil and Filter

Tools Required: Oil filter wrench, socket set, oil catch pan, funnel.
Sub-steps:
- Place the oil catch pan under the engine.
- Remove the drain plug using a socket wrench and let the old oil drain completely.
- Replace the drain plug and tighten it to the manufacturer’s specifications (typically around 30 ft-lbs).
- Use the oil filter wrench to remove the old oil filter.
- Apply a small amount of new oil to the rubber gasket of the new oil filter.
- Install the new oil filter by hand until snug, then tighten slightly more (do not over-tighten).
- Refill the engine with new oil through the oil filler cap, using the recommended oil type (usually 0W-20 for Honda).
- Start the engine and let it run for a minute, then check the oil level with the dipstick and add oil if necessary.

3. Tire Rotation

Tools Required: Jack stands, lug wrench, torque wrench.
Sub-steps:
- Use the jack to lift the vehicle and secure it on jack stands.
- Loosen the lug nuts on all four tires with the lug wrench.
- Remove the tires and rotate them according to the recommended pattern (front to rear and vice versa).
- Reinstall the tires and hand-tighten the lug nuts.
- Lower the vehicle and use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically around 80 ft-lbs).

4. Inspect Brake Fluid

Tools Required: Clean cloth, brake fluid tester (optional).
Sub-steps:
- Locate the brake fluid reservoir under the hood.
- Check the fluid level; if low, add the recommended brake fluid (DOT 3 or 4).
- Inspect the fluid condition; if it appears dark or contaminated, consider a brake fluid flush.
