1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the 12V battery if working on electrical components.

2. Inspect Battery and Charging System

Sub-steps:
1. Access the battery compartment.
2. Inspect battery connections for corrosion or loose terminals.
3. Use a multimeter to check the battery voltage (should be around 12.6V when fully charged).
4. If the battery is faulty, replace it with a compatible Tesla battery.

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if thickness is below 3mm.
3. Check brake fluid level and condition, replacing fluid if it is dark or contaminated.
4. Reassemble the wheel and torque lug nuts to manufacturer specifications.

4. Tire Inspection and Maintenance

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to recommended PSI.
2. Inspect tread depth using a depth gauge; replace tires if tread is below 2/32 of an inch.
3. Rotate tires if necessary, following the manufacturer's recommended rotation pattern.

5. Software Update

Sub-steps:
1. Connect the vehicle to a Wi-Fi network.
2. Navigate to the software update section in the settings menu.
