Solution

1. Preparation

Gather tools: Tesla mobile app, tire pressure gauge.
Ensure the vehicle is parked in a garage or warmer environment if possible.

2. Battery Preconditioning

Activate battery preconditioning through the Tesla app or vehicle settings before driving.
- Access the "Climate" section in the app.
- Turn on "Precondition Battery" to warm the battery for optimal performance.

3. Tire Maintenance

Check and adjust tire pressure.
- Remove valve stem caps and use a tire pressure gauge to verify pressure.
- Inflate tires to the manufacturer-recommended PSI for winter conditions (usually higher than summer settings).

4. Optimize Cabin Heating

Use seat heaters instead of cabin heating to reduce battery load.
Set the cabin temperature to a lower setting to conserve energy.

5. Software Update

Ensure the vehicle's software is up to date.
- Connect to Wi-Fi and check for updates in the vehicle’s settings menu under "Software".
