HINT:
*1: Some phones, cases or cover type wireless chargers may not cause the green
indicator to illuminate even though it is fully charged. Check the mobile device
to confirm charge status. Please refer to precaution for the details (See page

).
*2: If foreign matter is present between the mobile wireless charger cradle assembly and a compatible rechargeable device, such as a cellular phone, charging efficiency is lowered and the foreign matter may heat up. If the mobile wireless charger cradle assembly detects heat from the foreign matter, the indicator lights will blink.
(c) When charging of the wireless charger stops temporarily
(1) If any of the following operations are performed with the electrical key transmitter sub-assembly present, charging may stop temporarily:
- Locking/unlocking the doors by touching the door handle
- Opening/closing the doors
- Starting the engine
- Locking the doors by pressing the lock button on the electrical key transmitter sub-assembly
- When the electrical key transmitter sub-assembly is out of the detection area
(2) If the mobile wireless charger cradle assembly surface becomes too hot during charging operation, the indicator lights (green and amber) on the mobile wireless charger cradle assembly will blink and charging will be canceled. If the surface cools down, the indicator light (green) will be illuminated and charging will be resumed.
