Buzzer Cancel Setting

The buzzer cancel setting, which is a setting of the buzzer function of the combination meter, can disable the driver's seat belt buzzer, front passenger's seat belt buzzer and back-up warning buzzer (A/T reverse buzzer).

NOTE: Basically, these buzzers should be set on for safety driving. However, only if it is necessary to set the buzzer off for some reason, perform the following procedures.
