Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery to prevent electrical hazards.

2. Inspect and Replace Fluids

Engine Oil

Check oil level using the dipstick; if low, top off with the manufacturer's recommended oil type.
If oil appears burnt, perform an oil change.
- Drain the old oil using a socket set and remove the oil drain plug.
- Replace the oil filter with a new one.
- Refill with new engine oil (5W-20 or as specified in the owner’s manual).

Transmission Fluid

Check fluid level with the dipstick; if low, add fluid as needed.
If the fluid is burnt, consider a transmission fluid flush.
- Locate the transmission fluid drain plug and remove it.
- Replace the fluid with the manufacturer-recommended transmission fluid.

3. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear.
If pads are worn down to the backing plate, replace with new pads and resurfaced or new rotors.
- Use a torque wrench to tighten bolts to the manufacturer’s specifications.

4. Wiring Inspection

Visually inspect wiring and harnesses around the engine bay for fraying or damage.
Repair or replace any damaged wiring using electrical tape or heat-shrink connectors as needed.
