Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Check Engine Oil and Filter

Remove the oil dipstick and wipe it clean.
Insert it back and remove again to check the oil level; top off if low using the manufacturer-recommended oil type.
If the oil is dirty, proceed to change the oil filter and oil:
- Remove the old oil filter using an oil filter wrench.
- Install the new oil filter, applying a small amount of oil to the gasket.
- Drain old oil from the oil pan using a socket set and replace with new oil.

3. Inspect Tires

Check tire pressure with a tire pressure gauge and inflate to the recommended PSI.
Inspect tire tread for wear; replace tires if tread depth is below 2/32 of an inch.

4. Replace Air Filter

Open the hood and locate the air filter housing.
Remove the clips or screws securing the air filter cover.
Take out the old air filter and replace it with a new one, ensuring it fits securely.

5. Reconnect Battery

Once all maintenance tasks are completed, reconnect the negative battery terminal.

6. Clear Error Codes

Use the OBD-II scanner to clear any stored error codes after maintenance is completed.
