## NHTSA's summary

TT: A very small percentage of customers experience operational difficulties with some telematics features which they cannot resolve on their own. These resources, in conjunction with the Repair Manual, are for dealership personnel to assist those customers with user issues, user errors, and compatibility issues with other vehicle systems and external applications encountered while operating telematics features. Toyota has developed and provided the following Telematics Diagnostic Guide to assist dealer technicians.
