54B-417

If any of the following conditions is met with the igni-
tion switch at "ON" or "ST", the ETACS-ECU illumi-
nates, flashes or extinguishes the seat belt indicator 
by using the driver's seat belt switch signal and the 
vehicle speed signal sent from the combination 
meter.

• Illuminates when the ignition switch is at "ON" 

and the seat belt switch is turned on (the driver's 
seat belt is unfastened).

• Flashes and illuminates the indicator 12 cycles 

(after 0.5 seconds) if any of the following condi-
tions is met when sixty seconds or more have 
elapsed since the ignition switch is turned "ON". 
One cycle consists of five-second "flashing" and 
then three-second "illumination".

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 this timer operation has been acti-

vated, it will not be activated again until the 
vehicle speed reduces to 3 km/h (2 mph) or 
less even if any of the following conditions is 
met.

• The indicator stops illuminating 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.
