Solution

1. Preparation

Tools Required: Tesla app for diagnostics, tire pressure gauge.
Ensure the vehicle is parked on a flat surface and the battery is charged to at least 20%.
Verify that the vehicle is in park mode.

2. Software Update

Access the vehicle’s settings and navigate to the software update section.
If an update is available, connect to Wi-Fi and follow on-screen prompts to install the update.

3. Battery Health Check

Review the battery health and usage statistics.
If the battery health is below 80%, consider scheduling a service appointment for battery inspection or replacement.

4. Tire Inspection

Use a tire pressure gauge to check all four tires.
Inflate tires to the recommended pressure as indicated on the driver’s door jamb.
Inspect tires for wear or damage; replace if necessary.

5. Climate Control Management

Set climate control to a moderate temperature, ideally between 68°F and 72°F (20°C - 22°C).
Turn off heated seats and steering wheel if not needed.
Disable any unnecessary accessories that may draw power.

6. Phantom Drain Mitigation

Ensure the vehicle is fully updated with the latest software.
Disable features such as Sentry Mode and Cabin Overheat Protection if not required during long periods of inactivity.
Regularly monitor battery drain when parked, and report significant issues to Tesla service.
