Solution

1. Preparation

Tools Required: Tesla mobile app, OBD-II scanner (if applicable).
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Update Software

Access the vehicle’s touchscreen and navigate to the “Software” tab.
Check for updates and install any available software updates, as they may contain battery management optimizations.

3. Inspect Background Processes

Open the Tesla mobile app and review any active applications that may be running in the background.
Disable unnecessary features like “Sentry Mode” or “Always Connected” if not required.

4. Tire Maintenance

Check tire pressure using a tire gauge; ensure all tires are inflated to the recommended PSI (found on the driver’s side door jamb).
Rotate or replace tires if they are worn, as improper tires can lead to increased rolling resistance and energy consumption.

5. Battery Configuration

If the vehicle has a battery management system, access it through the settings menu and ensure it is configured for optimal efficiency.
Set charging limits to 80-90% for daily use to prolong battery life.
