COMMUNICATION FUNCTION PAUSING
Before performing inspections or repairs which may cause warning messages to be displayed or DTCs to be stored, such as a simulation test or road test, it is necessary to enter communication function pausing mode so that unnecessary warning messages are not sent to the TOYOTA Connect Center.
Communication function pausing mode
Enter communication function pausing mode
Turn the ignition switch off.
Connect the GTS to the DLC3.
Start the hybrid control system.
Turn the GTS on.
Enter the following menus: Body Electrical / Telematics
After completing maintenance work, be sure to cancel the communication function pausing mode.

STRICT PROHIBITION OF MANUAL EMERGENCY CALL USING EMERGENCY CALL SERVICE
Do not make an emergency call when not in emergency situations. For inspections, use the manual maintenance check.
If the emergency call service is used to connect to the TOYOTA Connect Center when not in an emergency situation, an unnecessary workload will be generated at the TOYOTA Connect Center. This may cause a delayed response by the TOYOTA Connect Center to other emergency calls.
If emergency vehicles are dispatched due to an accidental operation of the emergency call switch, you may be charged or punished according to related laws.
If the emergency call switch is accidentally operated;
If the emergency call switch is accidentally operated, contact the TOYOTA Connect Center to tell them that the call was made by mistake.
An emergency call cannot be halted or finished from the vehicle. Only the TOYOTA Connect Center can halt or finish the call.
If the TOYOTA Connect Center cannot be informed that the call was made by mistake, the center will report to authorities, emergency facilities and dealerships in compliance with its agreements. As a result, emergency vehicles may be dispatched.
PRECAUTION FOR TOYOTA CONNECT
When replacing the telematics transceiver, make sure to replace it with a new one.
Before replacing the telematics transceiver, refer to Service Bulletin.
If any of the following parts are replaced, refer to Work Procedure of When Replacing or Removing/Installing Parts.
Telematics transceiver
Mobilephone battery
When replacing the telematics transceiver, it is not necessary to cancel the TOYOTA Connect contract. (If canceled a new TOYOTA Connect contract needs to be created after replacement.)
On this model, the telematics transceiver functions as the TOYOTA Connect device and has the ID.
INSPECTION PROCEDURE FOR TELEMATICS TRANSCEIVER
The telematics transceiver uses an LTE (Long Term Evolution) type radio wave signal. The radio wave signals and communication lines may occasionally be unstable depending on time or location factors. Therefore, network access errors may occur intermittently because of radio wave signal conditions. To determine if there is a problem, it may be necessary to make a judgment based on the frequency of the phenomenon or by making a comparison with a comparable type of cell phone.
Disassembly of the telematics transceiver is not permitted (the case cannot be opened). If the telematics transceiver malfunctions, replace it.
PRECAUTIONS FOR EMERGENCY CALL SERVICE
Depending on the troubleshooting method, a manual maintenance check may be performed.
Communication charges are not incurred for the manual maintenance check because the telematics transceiver is used for communication (the communication cost is included in the TOYOTA Connect cost).
AUTOMATIC MAINTENANCE CHECK FOR EMERGENCY CALL SERVICE
The emergency call system regularly performs an automatic maintenance check and communication test with the TOYOTA Connect Center so that the emergency call service can always function correctly. There are no operations required to initiate an automatic maintenance check. The automatic maintenance check is performed as follows:
The automatic maintenance check ends 1 to 2 minutes after it starts.
During the automatic maintenance check, a telephone call or network access is not possible using the telematics system. In this case, wait several minutes before trying again.
If communication is interrupted for some reason after the automatic maintenance check has started, the automatic maintenance check will resume the next time the ignition switch is turned to ON.
There are no communication charges incurred for the manual and automatic maintenance check because the telematics transceiver is used for communication (the communication cost is included in the TOYOTA Connect cost).
IF AN EMERGENCY CALL CANNOT BE MADE
The emergency call service may not be available, or its quality may deteriorate in the following cases. (For details, refer to the terms of service and operation manual for the device.)
| Cause | Details |
|---|---|
| Communication is interrupted due to malfunctions in the TOYOTA Connect device or any other related device. | The TOYOTA Connect device does not operate normally, such as when the device is damaged or malfunctioning due to an impact caused by a collision. |
| Communication is interrupted due to a TOYOTA Connect Center system error. | ·
The TOYOTA Connect Center system may need either periodic or urgent maintenance. ·
An extreme volume of emergency calls is made to the TOYOTA Connect Center due to a large-scale traffic accident or fire. ·
Malfunctions or problems with the TOYOTA Connect Center system. ·
The TOYOTA Connect Center system is damaged due to a fire. ·
The emergency call service is suspended or halted due to emergency call provider reasons. |
| Communication is interrupted due to the network used for the emergency call system.* | ·
The registered vehicle is located outside the cellular phone service area used for the emergency call system. ·
The vehicle is overseas. ·
The vehicle is in a cellular phone service area where communication is not possible, such as an indoor environment, a basement parking area, mountains, tunnels or beside a building. ·
Network availability or the time of use is limited, such as when cellular phone networks or public fixed networks (including junction networks) are extremely busy. ·
Network availability is limited by the communication service provider due to a large-scale disaster. ·
The cellular phone network or public fixed network (including junction networks) service used for the emergency call system is suspended or halted due to accidents, maintenance or construction. |
| The TOYOTA Connect Center system cannot determine the vehicle location. | ·
The vehicle is in an area where the Global Positioning System (GPS) radio waves cannot be received or where it is difficult for radio waves to penetrate, such as an indoor environment, a basement parking area, mountains, tunnels or beside a building. ·
The vehicle location cannot be determined normally or accurately because the vehicle is in the following areas: -
Areas that cause a large error of the location calculation using the GPS, such as in tunnels or a densely built-up area, or after getting off a ferry. -
Areas that cause a large error in map matching due to an old map database. ·
The GPS is malfunctioning. |
| Others | ·
Although a manual call is made, the situation cannot be confirmed because the user cannot respond to questions from the TOYOTA Connect Center. ·
The TOYOTA Connect contract has not been established, the user fell behind in payments or canceled the service. ·
The emergency call service start procedure has not been completed. |
*: Even when the vehicle is within the cellular phone service area, it may be difficult to make emergency or phone calls due to radio wave signal conditions or busy lines. In this case, it may not be possible to access the TOYOTA Connect Center. As a result, no calls can be made to ask for rescue in the event of a traffic accident. If emergency calls cannot be made, use a landline telephone or cellular phone.
ALARM NOTIFICATION FUNCTION
If the theft deterrent system is activated, the TOYOTA Connect Center makes a phone call to the customer.
When servicing the vehicle, make sure that the vehicle does not experience any conditions that could cause a telephone call to be made by a TOYOTA Connect operator.
Before performing inspections or repairs which may activate the alarm notification function, be sure to inform the customer that they may receive a telephone call from a TOYOTA Connect operator.
PRECAUTION FOR MOBILEPHONE BATTERY
The mobilephone battery is a Lithium-ion type battery and can be charged from the telematics transceiver.
When ACN (Automatic Collision Notification) is performed, the mobilephone battery provides power to the telematics transceiver.
The mobilephone battery must not be replaced while an ACN call is in progress.
When a Manual Emergency Call is made, the mobilephone battery is not used as the power source.
When it is time to replace the mobilephone battery, the emergency call switch red indicator will come on.
The telematics transceiver will also store a DTC or specific vehicle control history (RoB) code.
