Kia Sorento: Limitations of the system

• The Kia Sorento Digital Key 2 interface may experience functional failures under the following operational conditions:

  • The internal battery level of your smartphone or the main Kia Sorento vehicle battery is completely discharged.

  • The NFC or Bluetooth radio modules are turned off within your smartphone system settings menu.

  • The mobile device is enclosed in a thick metallic protective case, or physical credit cards and RFID shielding materials sit directly against the rear antenna of the smartphone.

  • The dedicated NFC card key (if equipped) is held alongside other contactless smart cards, stored in a shielded leather wallet, or placed in a metallic card holder.

  • Strong electromagnetic interference or high-frequency radio signals are emitted by nearby vehicle transmitters or heavy industrial equipment.

  • A wireless communication error occurs due to metallic smartphone covers or attached third-party magnetic accessories interfering with the Digital Key 2 NFC transceiver module. If a key communication fault occurs, remove the protective smartphone cover and retry the authentication process.

• Your mobile phone may fail to execute remote vehicle management commands under these scenario conditions:

  • Essential system communication routines or high-priority phone tasks are running concurrently (such as an active cellular phone call, an emergency call dispatch, continuous audio streaming, or background contactless mobile payment processing).

  • The mobile device is actively connected to wireless earphones or Bluetooth headsets handling live call audio or system notifications.

  • Background execution of the Digital Key 2 application is restricted by OS power-saving features, custom battery optimization profiles, or mobile manufacturer application launch priority policies.

This device complies with Part 15 of the FCC rules.

System operation remains subject to the following two legal and operational conditions:
