Solution

1. Preparation

Gather tools such as a tire pressure gauge and a charging cable if necessary.
Ensure the vehicle is parked on a flat surface and turn off the ignition.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to "Software" in the settings menu.
Check for updates and install any available updates.

3. Tire Pressure Adjustment

Remove the valve cap from each tire.
Use a tire pressure gauge to check the current PSI.
Inflate tires to the manufacturer's recommended pressure (usually found on the driver's side door jamb).
Replace valve caps securely after checking.

4. Energy Consumption Review

Access the “Energy” menu on the central display.
Monitor the last several drives for patterns in energy usage.
Adjust driving habits to reduce aggressive acceleration and increase regenerative braking.

5. Charging Equipment Inspection

Inspect the charging cable and connectors for damage or wear.
Test the charging station with another vehicle if possible to ensure it is functioning correctly.
If using a home charger, check circuit integrity and ensure it is rated for the vehicle's charging requirements.

6. Battery Health Check

Schedule an appointment through the Tesla app to have the battery evaluated at a service center if significant issues are detected.
Provide the service technician with detailed information on driving patterns and symptoms experienced.
