1. Preparation

Ensure the vehicle is in a safe location and parked.
Check that the vehicle's battery is sufficiently charged to avoid interruptions during troubleshooting.

Press and hold both scroll wheels on the steering wheel simultaneously until the touchscreen goes black and the Tesla logo appears.
Wait for the system to reboot, which may take a few minutes.

3. Reset Network Settings

Navigate to the "Settings" menu on the touchscreen.
Select “Wi-Fi” and locate the option to forget the current network.
Re-enter the Wi-Fi credentials (SSID and password) for the desired network.

Go to "Controls" > "Software" to check for any available software updates.
If an update is available, ensure the vehicle is connected to a Wi-Fi network and follow the prompts to update the software.
