Ignition key reminder tone alarm function
When the driver's door is opened with the ignition key inserted in the ignition key cylinder (ignition switch is in the OFF position,) the tone alarm sounds intermittently (horning sound) to indicate that the ignition key has not been removed.
Light reminder tone alarm function
When the taillight or headlight is ON, if the ignition key is removed and the driver's door is opened, a tone alarm will sound continuously to warn that the light is illuminated. However, if the taillight or headlight has been turned off by the headlight automatic-shutdown function, the tone alarm will not sound.
Seat belt tone alarm function
The ETACS-ECU sounds the tone alarm for six seconds if the ignition switch is turned "ON" or "ST" while the seat belt buckle switch (driver's side) is on (the driver's seat belt is not fastened).
If any of the following conditions is met with the ignition switch at "ON" or "ST," the ETACS-ECU sounds the tone alarm by using the seat belt buckle switch (driver's side) signal and the vehicle speed signal.
- Sounds the tone alarm for six seconds when the ignition switch is turned "ON" with the seat belt buckle switch (driver's side) on (the driver's seat belt is not fastened) (timer operation).
- Sounds the tone alarm 12 cycles (after 0.5 seconds) if any of the following conditions is met when sixty seconds or more have elapsed since the ignition switch is turned "ON." One cycle consists of five-second "on" and then three-second "off."
NOTE: Once the tone alarm has sounded 12 cycles, it does not sound again until the vehicle speed reduces to 3 km/h (2 mph) or less even if any of the following conditions is met.
a. The vehicle speed has reached 8 km/h (5 mph) while the seat belt buckle switch (driver's side) is turned on (driver's seat belt is not fastened) with the ignition switch "ON.
b. The seat belt buckle switch (driver's side) has been turned on (driver's seat belt has not been fastened) for at least ten seconds while the ignition switch has been turned "ON" and the vehicle speed has been 8 km/h (5 mph) or more.
The tone alarm stops sounding if the ignition switch or the seat belt buckle switch (driver's side) is turned off (the driver's seat belt is fastened) while the timer operation is active.
