1. Remove the dipstick and wipe it clean.
2. Insert it back into the tube and remove it again to check the oil level and condition.
3. If the oil is low or burnt, change the oil and filter.

5. Inspect Belts and Hoses

Sub-steps:
1. Visually check all drive belts for cracks, fraying, or glazing.
2. Squeeze hoses to check for softness or leaks.
3. Replace any damaged belts or hoses.

6. Brake System Inspection

Sub-steps:
