1. Preparation
  • Gather tools: mobile device for accessing the Tesla app, and a laptop with Tesla diagnostics software if needed.
  • Ensure the vehicle is parked in a safe location with ample space around it.
2. Software Update

  • Navigate to Software and check for available updates.
  • If an update is available, follow the prompts to install the latest software version, which may resolve software-related warning lights.
3. Tire Pressure Check
