3. Battery Management

If the battery level is low, charge the vehicle to at least 20%.
Inspect the high-voltage battery connections for any signs of damage or corrosion.

4. Resolve Error Codes

If error codes are present, take note of them and refer to Tesla's service documentation for specific troubleshooting steps.
Clear any non-critical error codes and test if the issue persists.

5. Temperature Management

If battery or motor temperatures are too high, allow the vehicle to cool down before operating.
Check for any thermal management system faults using the diagnostic tool.

6. Brake System Inspection

Visually inspect brake pads and rotors for wear.
Test the brake pedal for firmness and listen for unusual noises when applying.
