Purpose
KEY warning light (red)
The KEY warning indicator light (red) notifies the user that the engine cannot be started, the remote transmitter is outside of the vehicle, or that there is a malfunction in the system.
KEY indicator light (green)
The KEY indicator light (green) notifies the user that the engine starting conditions have been met or that the remote transmitter battery voltage is depleted.
Function
KEY warning indicator light (red)
When a malfunction is detected in the system, the KEY warning indicator light (red) illuminates..
The KEY warning indicator light (red) flashes if the engine cannot be started and when the ignition is switched to ACC or ON (engine off or on) and the transmitter is taken outside of the vehicle..
KEY indicator light (green)
When the engine-starting conditions have been met, the KEY indicator light (green) illuminates..
If the remote transmitter battery voltage is depleted, the KEY indicator light (green) flashes..
Construction
The KEY warning indicator light (red)/KEY indicator light (green) are built into the instrument cluster.

Operation
Warning indicator light (red)
If a malfunction is detected in the system, the engine cannot be started, or the remote transmitter is outside of the vehicle, the start stop unit sends a warning request signal via CAN transmission to the instrument cluster.
KEY indicator light (green)
If the engine starting conditions have been met, the start stop unit sends a KEY indicator light (green) illumination request signal via CAN transmission to the instrument cluster.
If the remote transmitter battery voltage has been depleted, the start stop unit sends a battery voltage depletion display request signal via CAN transmission to the instrument cluster.

Instrument Cluster Disassembly/Assembly
CAUTION:
If the instrument cluster is hit forcefully during disassembly such as by
being dropped, it could get damaged and the system may not operate normally.
When disassembling the instrument cluster, perform the procedure on a workbench
on clean clothes being careful not to drop ...
