Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turned off.
Gather necessary tools and parts for any potential repairs.

2. Software Update

Connect the vehicle to Wi-Fi.
Navigate to the Software menu on the display.
Check for and install any available updates to ensure the vehicle operates with the latest software enhancements.

3. Inspect Battery and Connections

Open the frunk (front trunk) and visually inspect the battery connections for any loose or corroded terminals.
Tighten any loose connections with a socket wrench (typically a 10mm socket).
If corrosion is present, clean the terminals with a battery terminal cleaner or a mixture of baking soda and water.

4. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires as needed to match the manufacturer’s recommended pressure, which can be found on the driver’s door jamb sticker.

5. Reset System

Power cycle the vehicle by holding down both scroll wheels on the steering wheel until the screen turns off and then back on.
Monitor the display for any changes to the warning light after the reset.
