Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked in a garage or warm place to avoid additional cold exposure.
Disconnect any aftermarket accessories that might drain the battery.

2. Update Software

Connect the Model Y to Wi-Fi.
Go to the settings menu on the touchscreen.
Check for and install any available software updates that could improve range performance.

3. Optimize Battery Management

Utilize "Precondition" settings: Schedule preconditioning of the battery and cabin while plugged in.
Activate "Range Mode" if available, which optimizes energy consumption.

4. Tire Maintenance

Check tire pressure with a tire gauge.
Inflate tires to the manufacturer's recommended PSI, as lower temperatures can decrease tire pressure.

5. Heating Strategy

Use seat heaters instead of cabin heat to conserve battery.
Set the cabin temperature to a lower setting while driving.
