Solution

1. Preparation

Gather tools and parts needed for the service.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Oil Change

Sub-steps:
1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug with a socket wrench and let the oil drain completely.
3. Replace the oil drain plug and torque it to the manufacturer’s specifications (typically around 25-30 ft-lbs).
4. Remove the old oil filter using an oil filter wrench.
5. Apply a small amount of new oil to the rubber gasket of the new oil filter and install it, tightening by hand.
6. Refill the engine with the recommended oil type (typically 0W-20) and capacity as specified in the owner’s manual.

3. Fluid Check and Replacement

Sub-steps:
1. Check the transmission fluid level using the dipstick; add fluid if low or replace if dirty.
2. Inspect coolant levels in the reservoir and top off if necessary.
3. Check brake fluid level and replace if it's below the minimum line.

4. Filter Replacement

Sub-steps:
1. Remove the air filter housing cover to access the engine air filter; replace with a new filter.
2. Remove the cabin air filter cover and replace the cabin air filter if it is dirty or clogged.

5. Tire Inspection

Sub-steps:
1. Use a tire pressure gauge to check all tire pressures; inflate to recommended levels if necessary.
2. Inspect tires for tread wear and replace tires if tread is below 2/32 of an inch.
