- If low, top up with the recommended engine oil.
Check coolant level:
- Inspect the reservoir and refill with the appropriate coolant if low.
Check brake fluid:
- Inspect the reservoir and add brake fluid to the correct level.

4. Battery Inspection

Visually inspect the battery for corrosion around terminals.
Clean any corrosion with a mixture of baking soda and water.
Tighten battery terminals securely.

5. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate tires to the manufacturer's recommended PSI if low.

6. Test Drive and Reset Codes

Reconnect the battery.
