Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect Fluid Levels

Oil Level Check:
- Remove the dipstick, wipe it clean, reinsert, and remove again to check oil level.
- If oil is low, top off with the manufacturer-recommended oil. If burnt, consider an oil change.
Transmission Fluid Level Check:
- Remove the transmission dipstick, check the fluid level and condition.
- If burnt or low, replace the transmission fluid and filter according to the manufacturer's recommendations.

3. Brake Inspection

Remove Wheel:
- Use a jack to lift the vehicle and securely place it on jack stands.
- Remove the lug nuts and wheel to access brake components.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; if worn down, replace them.
- Inspect the rotors for scoring or overheating signs; replace if necessary.

4. Check Belts and Hoses

Visually inspect all engine belts and hoses for signs of wear, cracking, or burning.
Replace any damaged belts or hoses as needed.

5. Reassemble and Test

Reinstall the wheel and lug nuts, tightening them to the manufacturer's torque specifications.
Reconnect the battery, start the engine, and allow it to idle to check for any remaining smells or warning lights.
