Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Wear safety goggles and gloves as needed.

2. Perform Scheduled Maintenance

a. Oil Change

Drain Old Oil:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow old 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 oil filter.
3. Install the new oil filter by hand until snug.
Add New Oil:
1. Replace the drain plug and torque it to the manufacturer's specification (typically around 30 ft-lbs).
2. Using a funnel, add the appropriate type and amount of new oil (typically 0W-20 or 5W-20 depending on climate) as specified in the owner’s manual.

b. Replace Air Filter

Remove Air Filter Housing:
1. Open the hood and locate the air filter housing.
2. Unsnap or unbolt the housing cover and remove it.
Install New Air Filter:
1. Take out the old air filter and inspect the housing for debris.
2. Place the new air filter into the housing ensuring a proper fit.
3. Reattach the housing cover securely.

c. Check and Adjust Tire Pressure

Tire Inspection:
1. Use a tire pressure gauge to check the pressure of all four tires.
2. Inflate tires to the recommended PSI (found on the driver’s door jamb).
Tread Depth Check:
1. Use a tread depth gauge to measure the tread on each tire.
2. Replace tires that do not meet the minimum tread depth specifications.

3. Reset Maintenance Light

Turn the ignition switch to the "ON" position without starting the engine.
Press the gas pedal three times quickly within five seconds.
The maintenance light should turn off.
