Solution

1. Preparation

Gather tools and parts: socket set, torque wrench, oil filter wrench, fluid containers, gloves, rags, and maintenance parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working on electrical components.

2. Oil Change

Drain Old Oil:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug with a socket wrench (torque: 25 Nm).
3. Allow the oil to drain completely.
Replace Oil Filter:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a small amount of new oil to the rubber gasket of the new filter.
3. Install the new filter by hand until snug (do not overtighten).
Add New Oil:
1. Replace the oil drain plug and torque to specification.
2. Pour in new engine oil (refer to owner's manual for the correct specification and capacity).
3. Start the engine and let it run for a few minutes, then check for leaks.

3. Air Filter Replacement

Open the hood and locate the air filter housing.
Remove the clips or screws securing the housing cover.
Remove the old air filter and clean the housing.
Install the new air filter, ensuring it fits snugly.
Reattach the housing cover.

4. Brake Inspection and Replacement

Inspect Brake Pads and Rotors:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for thickness; replace if less than 3 mm.
3. Check rotors for scoring or warping.
Replace Brake Pads:
1. Remove caliper bolts and slide off the caliper.
2. Remove old brake pads and replace with new ones.
3. Reattach the caliper and torque bolts to specification.

5. Tire Maintenance

Check tire pressure using a gauge; inflate to the recommended PSI.
Inspect tread depth using a tread depth gauge; replace tires if below 2/32 inches.
Rotate tires if needed to promote even wear.
