Key Reminder System

When the driver door is opened when the ignition SW off but the ignition key is still in the key cylinder (Unlock warning SW on), a signal is input from the unlock warning SW to TERMINAL 7 of the combination meter, and from the door courtesy SW (Driver's side) to TERMINAL 8 of the combination meter. As a result, the buzzer in the combination meter sounds, warning the driver that the key is still in the key cylinder.
