Audible Warning Device: Description and Operation

CHIME WARNING/REMINDER SYSTEM

GENERAL DESCRIPTION

IGNITION KEY REMINDER TONE ALARM FUNCTION
When the driver's door is opened (driver's door switch ON) without removing the ignition key [ignition switch to "LOCK" (OFF) or "ACC" position], the tone alarm will sound intermittently to remind the driver that the ignition key has not been removed.

LIGHT REMINDER TONE ALARM FUNCTION
When the driver's door is opened (driver's door switch ON) with lighting switch (taillight switch or headlight switch) in the ON position and ignition switch in the "LOCK" (OFF) or "ACC" position, the tone alarm will sound continuously to remind the driver that the lights (taillights or headlights) are ON. This function does not work if the taillights or headlights are switched off through the headlight automatic shutdown function. In addition, the ignition key reminder tone alarm function has a priority over this function.

DOOR AJAR TONE ALARM FUNCTION
If any of the doors are open, with ignition switch "ON" and with vehicle running at the speed of 8 km/h (5 mph) or more, ETACS-ECU makes buzzer sound.

LOW WASHER FLUID LEVEL TONE ALARM FUNCTION
If 10 seconds have passed after ignition switch has been turned "ON," and then, washer fluid level switch remains at the position "ON" (alarms for washer fluid level getting low) for two seconds or more, ETACS-ECU makes buzzer sound. Buzzer sounds just once after setting ignition switch to the position "ON."

SEAT BELT TONE ALARM FUNCTION
If the seat belt is unfastened (the seat belt switch: ON) for ten seconds after the ignition switch has been turned on for 60 seconds or more, or the vehicle speed reaches 8 km/h (5 mph) or more while the seat belt is unfastened (the seat belt switch: ON), the ETACS-ECU will sound the tone alarm (the tone alarm will sound for five seconds every three seconds 12 times). If the seat belt is fastened or the ignition switch is turned off while the tone alarm is sounding, the tone alarm will stop sounding.

LOW FUEL LEVEL TONE ALARM FUNCTION
If seven seconds have passed after ignition switch has been set to the position "ON," and then, low fuel level signal (low fuel level alarm light) from ECM or PCM, is turned "ON," ETACS-ECU makes buzzer sound. Buzzer sounds just once after setting ignition switch to the position "ON."
