1. Tire Maintenance

Check Tire Pressure:
- Use a tire pressure gauge to measure each tire's pressure.
- Inflate tires to the manufacturer's recommended PSI (found on the driver’s door jamb).
Inspect Tires:
- Look for uneven wear, which may indicate misalignment or imbalance.
- Replace tires if tread depth is below 2/32 inches.

2. Air Filter Replacement

Locate the Air Filter:
- Open the hood and find the air intake box; it is typically located near the engine.
Remove the Air Filter:
- Unclip or unscrew the air intake box cover and remove the old air filter.
Install New Air Filter:
- Place a new air filter in the box, ensuring it fits snugly.
- Reattach the cover and secure it properly.

3. Engine Maintenance

Oil Change:
- Use the manufacturer's recommended oil grade and change the oil filter.
Spark Plug Inspection:
- Remove spark plugs and check for wear; replace if worn or fouled.

4. Fuel System Cleaning

Add Fuel System Cleaner:
- Choose a quality fuel system cleaner and follow the instructions for mixing with fuel.
Consider Professional Cleaning:
- If performance issues persist, have a professional clean the fuel injectors.

5. Driving Habits Adjustment

Smooth Acceleration:
- Accelerate gently and maintain steady speeds.
Limit Idling:
- Turn off the engine if parked for more than a minute.
Reduce Load:
- Remove unnecessary weight from the vehicle, such as heavy cargo and roof racks when not in use.
