54B-13

If any of the following conditions are met with the 
ignition switch at "ON" or "ST", the ETACS-ECU 
sounds the tone alarm by using the driver's seat belt 
switch signal and the vehicle speed signal from the 
combination meter.

Sounds the tone alarm for six seconds when the 
ignition switch is turned "ON" with the seat belt 
switch on (the driver's seat belt is not fas-
tened)(Timer function). 

Sounds the tone alarm 12 cycles (after 0.5 sec-
onds) if any of the following conditions are met 
when sixty seconds or more have elapsed since 
the ignition switch is turned "ON". One cycle con-
sists of five-seconds "on" and then three-seconds 
"off".

a. The vehicle speed has reached 8 km/h (5 

mph) while the seat belt switch is turned on 
(driver's seat belt is not fastened) with the 
ignition switch "ON".

b. The seat belt switch 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.

NOTE: Once the tone alarm has sounded 12 

cycles, it does not sound again until the vehi-
cle speed reduces to 3 km/h (2 mph) or less 
even if any of the following conditions is met.

The tone alarm stops sounding if the ignition 
switch or the seat belt switch is turned off (the 
driver's seat belt is fastened) while the timer 
operation is active.

Door ajar warning buzzer
The buzzer is sounded 4 times by the ETACS-ECU to warn the 
driver if any door is open when the ignition is switched ON and 
the vehicle speed reaches 8 km/h (5 mph) or faster. The buzzer 
will continue to sound for 4 times even if the ignition, door sta-
tus, or vehicle speed requirements are not maintained.
NOTE: The warning buzzer can be customized on vehicles 
equipped with a multi center display (middle grade type.) Refer 
to 

P.54B-28

.

.

Multi center display operation tone <vehicles with multi 
center display (middle grade type)>
The ETACS-ECU sounds the buzzer when the buzzer signal is 
sent from the center display.

.

Turn-signal light buzzer
The ETACS-ECU sounds the buzzer in sync with the turn sig-
nal lights or hazard warning lights.
NOTE: The turn-signal light buzzer can be customized on vehi-
cles equipped with a multi center display (middle grade type.)

CENTRAL DOOR LOCKING SYSTEM

.

Door unlocking by operating the driver’s door lock key cyl-
inder
When the ignition key is inserted in the driver’s door lock key 
cylinder and turned clockwise to unlock the driver’s door, the 
ETACS-ECU operates its door unlock relay and passes a cur-
rent through the door lock actuator of the driver’s door for 0.25 
seconds to unlock only the driver’s door.
When the ignition key is turned clockwise again, the 
ETACS-ECU operates its door unlock relay and passes a cur-
rent through the door lock actuators of all doors for 0.25 sec-
onds to unlock all doors.
NOTE: Vehicles with a multi center display (middle grade type) 
can be customized so that a single unlock operation will unlock 
all doors. (Refer to 

P.54B-28
