- Check the number of charge cycles and overall battery capacity.
- If battery degradation is significant, consult a Tesla service center for evaluation.
Tools Required: Tesla app.

3. Energy Consumption Review

Sub-steps:
- Navigate to the energy consumption section in the vehicle’s display.
- Analyze recent driving habits and patterns that may contribute to high energy usage.
- Adjust driving style to promote energy efficiency (e.g., gentle acceleration and braking).
Tools Required: Vehicle dashboard/display.

4. Software Update Check

Sub-steps:
- Connect the car to Wi-Fi and check for software updates in the settings menu.
- Follow prompts to download and install the latest firmware if available.
Tools Required: Wi-Fi connection.
