Solution
1. Preparation
  • Gather tools and equipment such as a tire pressure gauge and a mobile device for software updates.
  • Ensure the vehicle is parked on a level surface.
  • Disconnect any non-essential accessories or devices that draw power.
2. Tire Inspection and Adjustment
  • Check Tire Pressure:
    • Use a tire pressure gauge to measure the pressure of all four tires.
    • Inflate tires to the manufacturer's recommended PSI levels (found on the driver’s door jamb).
  • Inspect Tread Depth:
    • Use a tread depth gauge to measure the tread on all tires.
    • Replace tires if tread depth is below 2/32 inches.
3. Software Update
  • Access Software Settings:
    • Open the Tesla app or vehicle display settings.
    • Navigate to "Software" and check for available updates.
  • Install Updates:
    • Follow on-screen instructions to install any available software updates, ensuring the vehicle is connected to Wi-Fi.
4. Review and Adjust Regenerative Braking Settings
  • Access Regenerative Braking Settings:
    • Go to the "Driving" menu on the Tesla display.
    • Adjust regenerative braking to "Standard" for optimal energy recovery.
5. Battery Health Assessment
  • Check Battery Status:
    • Use the Tesla app to review battery health indicators.
    • If battery capacity is significantly reduced, consider consulting Tesla service for battery evaluation.
