Delay Timer
Important
Make sure not to install the delay timer
incorrectly (ON/OFF).
Off Delay Timer
(Seat safety switch timer)
The off delay timer is located under the left
side of the seat, and is linked to the seat
switch.
The signal continues to be output even if the
driver is away from the seat for 0.9 seconds
while driving, to prevent the engine from
turning off if the driver leaves the seat
instantaneously due to vibrations or similar
while driving.
