  4. CHECK CONNECTION TO "Wi-Fi" ACCESS POINT

    1. Check the conditions and procedure for establishing a "Wi-Fi" connection, and perform "Wi-Fi" connection again.

      Tip:

      • Considering the radio wave environment around the vehicle, move the vehicle and establish a "Wi-Fi" connection.

      • As there may be wave interference, disconnect other "Wi-Fi" compatible devices or "Bluetooth" compatible devices before establishing a "Wi-Fi" connection.

      • A "Wi-Fi" connection may not be able to be established in a region other than where the vehicle was sold.

      • Customer operation may be required when establishing a "Wi-Fi" connection.

      • A "Wi-Fi" connection can be established manually or automatically.

      • There are 3 ways to establish a manual connection: Connecting using simple setting, connecting by searching for a "Wi-Fi" access point and inputting a password, and connecting by inputting an SSID and password.

      • Even though an automatic connection is enabled, a connection can be established only when a "Wi-Fi" access point with the same SSID and password that were used for a previous connection exists.

      Result
