- Checks if the mobile phone is placed on the wireless charging unit.
- Alert message for contact with mobile phone is displayed on the instrument panel (for about 4 - 5 seconds).
- Activation method
- Overheating prevention
- Activation method
- If the thermistor temperature inside the wireless charging module rises above a certain level (158°F (70°C)), charging will stop to protect the mobile phone battery.
Information
- The amber LED of the charging display lamp blinks 10 times for 10 seconds, and then it is turned off for 50 seconds (total 60 seconds).
- The process is repeated for every 60 seconds.
- If the thermistor temperature falls below a certain level (149°F (65°C)), charging will restart.
- If the thermistor temperature inside the wireless charging module rises above a certain level (158°F (70°C)), charging will stop to protect the mobile phone battery.
Information
When the charging function is restarted, the orange LED of the charging indicator lamp is normally lit.
- Activation method
- Foreign matter detection
- Charging will be stopped if there is a coin or other metallic object between the wireless charging unit and the mobile phone.
[Foreign matter]
Information
- Foreign matter: All metallic objects such as coins, clips, and precious metals
- The amber LED of the charging display lamp blinks 10 times for 10 seconds, and then it is turned off for 50 seconds (total 60 seconds).
- The process is repeated for every 60 seconds.
CAUTION: Be careful as touching the foreign matter by hand may cause burns. - After the system has detected foreign matter and stopped charging the mobile phone, the charging will resume in about 60 seconds once the foreign matter has been removed.
Information
When the charging function is restarted, the amber LED of the charging display lamp will be turned on.
- Charging will be stopped if there is a coin or other metallic object between the wireless charging unit and the mobile phone.
- SMK unit LF frequency interference prevention
This function prevents interference between the wireless charging frequency and smart key unit frequency band.
- Wireless charging is stopped when the door is open or the SMK unit is in LF mode (searching for smart key). e.g. Wireless charging function is stopped if the driver carries the smart key out of the vehicle during IG ON.
Information
Charging will stop and the amber LED of the charging display lamp will turn off.
- It will return to normal operating status when the LF mode of the SMK unit is completed.
- Wireless charging is stopped when the door is open or the SMK unit is in LF mode (searching for smart key). e.g. Wireless charging function is stopped if the driver carries the smart key out of the vehicle during IG ON.
- Turn the wireless charging function ON/OFF with USM.
