Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Tires (if needed)

Sub-steps:
1. Remove the wheel covers or hubcaps, if applicable.
2. Use a lug wrench to loosen and remove the lug nuts, then take off the wheel.
3. Inspect the tire for any signs of damage, bulges, or uneven wear.
4. If replacement is needed, install new tires according to manufacturer specifications, ensuring proper tire pressure.
5. Reinstall the wheel and torque the lug nuts to the specified value (typically 80-100 ft-lbs for Tesla).

3. Inspect and Replace Brake Components (if needed)

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads for wear; they should be at least 3mm thick.
3. Check brake rotors for warping or discoloration.
4. If replacement is required, remove the caliper by unbolting it and replacing the pads and rotors as necessary.
5. Reassemble and torque bolts to manufacturer specifications (typically 25-35 ft-lbs for caliper bolts).

4. Inspect and Replace Drive Belt (if needed)

Sub-steps:
1. Open the front trunk to access the drive belt area.
2. Visually inspect the drive belt for cracks, fraying, or glazing.
3. If damaged, use a belt tool to release tension and remove the old belt.
4. Install the new belt according to the routing diagram typically found in the engine compartment.

5. Check Electrical Components

Sub-steps:
1. Inspect wiring harnesses and connectors in the battery compartment for signs of melting or burn marks.
2. Replace any damaged wiring or connectors as necessary to prevent overheating.
