Head Unit Notifications:
Head unit notifications are electronic messages that are displayed in the vehicle’s audio system screen. Customers who receive head unit notification regarding this Special Service Campaign are requested to schedule an appointment with their authorized dealer to have this Special Service Campaign completed.
When these messages are received by the vehicle’s Data Communication Module, the head unit will display a pop-up prompt stating that the vehicle has a new Special Service Campaign. The prompt will contain options to ‘Remind Me’ or to ‘View’ the message. If a customer chooses ‘Remind Me’, the customer can then choose to be reminded again on next trip, in 7 days, or in 30 days. If a customer views and then closes the message, the message will be available in the Notification App if the customer chooses to review it again. If the vehicle’s completion status remains incomplete for a period of 90 days from the message being viewed, the head unit may display a renotification pop-up prompt as an additional reminder to the customer to have this Special Service Campaign completed.
The message will completely clear from the vehicle once the following conditions are met: The Special Service Campaign is completed, the dealer has filed a claim, and the claim is approved by Toyota. Then the message will be cleared at the next clearing cycle, which currently happens daily. Owners who receive a head unit notification after having this Special Service Campaign completed can be advised to ignore the message. Owners with additional concerns can be directed to the Toyota Brand Engagement Center at 1-888-270-9371 Monday through Friday, 8:00 am to 8:00 pm, Saturday 9:00 am to 7:00 pm Eastern Time.
