Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while servicing.

2. Perform Scheduled Maintenance

Oil Change:
- Remove the oil drain plug using a socket set, allowing old oil to drain completely.
- Replace the oil filter using an oil filter wrench.
- Install a new oil filter and tighten it to manufacturer specifications.
- Reinstall the drain plug and torque it to the specified value (typically 25-30 Nm).
- Fill the engine with the appropriate grade of oil (check owner’s manual for specifications).
Fluid Checks:
- Inspect and top off brake fluid, coolant, and transmission fluid as necessary. Use the manufacturer-recommended fluids.
Tire Maintenance:
- Check tire pressures and inflate to the recommended PSI.
- Inspect tire tread for wear; replace if below safety standards.

3. Reset Service Light

Use the OBD-II scanner to reset the service light after maintenance is completed.
Alternatively, refer to the vehicle's manual for the manual reset procedure if no scanner is available.
