Solution

1. Software Update

Access the vehicle's touchscreen settings.
Navigate to "Software" and check for updates.
If an update is available, connect to Wi-Fi and download the update.
Follow prompts to install the update and restart the vehicle.

2. Battery Calibration

Fully charge the battery to 100% using a Supercharger or home charger.
Drive the vehicle until the battery level drops to 10%.
Charge the vehicle back to 100% again without interruptions.
This process recalibrates the battery management system for accurate range estimations.

3. Tire Inspection

Inspect all four tires for proper inflation using a tire pressure gauge.
Adjust tire pressure to the manufacturer's specifications (usually found on the driver's door jamb).
Check for any visible damage or excessive wear on the tires.
Rotate or replace tires if necessary, as they can impact range.

4. Energy Settings Adjustment

Access the "Driving" settings in the touchscreen menu.
Adjust settings such as "Chill Mode" to optimize energy consumption.
Disable unnecessary features like "Sentry Mode" or "Cabin Overheat Protection" when not needed.
Review and limit background apps that may be consuming battery power.
