Solution

1. Preparation

Tools Required: Tesla mobile app or onboard diagnostic screen
Verify the vehicle is parked in a garage or a controlled environment to mitigate cold exposure if possible.

2. Battery Management

Ensure that the battery is preconditioned before driving:
- Use the Tesla app to initiate pre-conditioning while the vehicle is still plugged in.
- Set the cabin temperature to a comfortable level to facilitate heating while the vehicle is charging.

3. Tire Maintenance

Inspect tire pressure:
- Use a tire pressure gauge to measure the current pressure.
- Inflate tires to the manufacturer-recommended PSI, which can be found on the door jamb sticker.

4. Cabin Heating Optimization

Adjust cabin heating settings:
- Use seat heaters instead of cabin heat to conserve battery.
- Utilize scheduled departure settings to heat the cabin while the vehicle is still charging.

5. Software and Updates

Check for software updates:
- Navigate to the software section in the vehicle’s settings and ensure it's updated to the latest version.
- If updates are available, download and install them.
