Solution

1. Preparation

Gather necessary tools and parts for the service.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety if required.

2. Oil Change

Drain Old Oil
- Position a drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench.
- Allow the old oil to fully drain into the pan.
- Replace the drain plug and torque it to the manufacturer's specifications (typically 20-25 Nm).
Replace Oil Filter
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a small amount of new oil to the rubber gasket of the new filter.
- Install the new oil filter and hand-tighten it.
Add New Oil
- Refill the engine with the appropriate type and amount of new oil as specified in the owner's manual.
- Use a funnel to avoid spills.
- Start the engine and let it run for a minute, then check the oil level with the dipstick and add oil if necessary.

3. Fluid Levels Check

Inspect and Top Off Fluids
- Check coolant level in the reservoir and add coolant if needed.
- Inspect brake fluid and add if below the minimum level.
- Check power steering fluid and windshield washer fluid levels and top off as necessary.

4. Tire Inspection

Check Tire Condition
- Inspect each tire for tread wear and damage.
- Measure tire pressure with a gauge and inflate to the recommended PSI.

5. Reset Maintenance Light

Reset the Service Indicator
- Use the vehicle’s dashboard controls to navigate to the settings menu.
- Find the option to reset the service light and follow the prompts.
- Alternatively, use an OBD-II scanner to reset the service reminder.
