will sound intermittently for approximately 6 seconds. If,however, the driver’s lap belt is fastened during that time, the
buzzer will be switched

Note that the warning light when the ignition switch isactivated will also illuminate when the ignition switch is turned
from the “LOCK” or “ACC” position to the “ON” position.

tions occur simultaneously: the key is in the key cylinder
(key-reminder switch A is switched ON), and the ignition
switch is at the “LOCK” or “ACC” position, and the driver’s
door is open (the door latch switch “open” is switched ON).
