Solution

1. Preparation

Ensure the vehicle is parked in a safe location.
Connect the vehicle to a charger to prevent total battery depletion during diagnostic procedures.

2. Update Software

Access the vehicle's touchscreen interface.
Navigate to 'Software' and check for any available updates.
If updates are available, download and install them, following the on-screen prompts.

3. Adjust Energy Settings

Go to 'Settings' on the touchscreen.
Disable or adjust settings for 'Sentry Mode', 'Cabin Overheat Protection', and 'Walk-Away Door Lock' if these features are not needed.
Consider turning off 'Always Connected' if not necessary for your usage.

4. Battery Health Check

From the Tesla app, review the 'Battery' section for health metrics.
If battery health is low (below 70%), consider scheduling a service appointment for a battery check.
