lBattery positive voltage is continuously applied to the key-reminder switch.l
If the driver’s door is opened (door switch ON) with the key inserted in the ignition switch (key-reminderswitch ON), the buzzer sounds to warn that the key has been left in the switch.
&eat belt warning>
lWhen the ignition switch is turned on, the timer circuit and pulse circuit will flicker the seat belt warning
light for approx. 6 seconds with the buzzer intermittently sounding.
lIf the seat belt is fastened for the while, the seat belt switch will be turned off and the buzzer will
stop.

lTurn on the ignition switch, and the transistor Tr will be turned on by the timer circuit. This will turn
on the power window relay allowing the power window to be opened and closed.
lTurn the ignition switch from on to off, and the timer circuit will be activated to keep transistor Tr
on for 30 seconds allowing the power window to be opened and closed.
Moreover, if the front door is opened, the timer circuit will stop to turn off the transistor Tr. This
will prevent the window from being opened and closed.
