3. Examine Energy Settings

Access the “Energy” tab on the touchscreen.
Review the “Trip” and “Lifetime” energy consumption statistics.
Identify any abnormal energy usage patterns and note any high consumption periods.

4. Optimize Battery Usage

Disable unnecessary background applications (e.g., heated seats, climate control if not needed).
Use the “Range Mode” option, if available, to maximize efficiency.
Ensure regenerative braking settings are optimized for your driving style.

5. Tire Pressure and Condition

Use a tire pressure gauge to check each tire’s pressure; inflate to the manufacturer’s recommended PSI.
Inspect tires for uneven wear or damage and replace if necessary.

6. Battery Health Assessment

Connect the vehicle to the Tesla app and navigate to the “Battery” section.
Review the health status and capacity of the battery pack.
If the battery is significantly degraded, consider contacting Tesla for replacement options.
