REV indicator light

The REV alarm system has the following
functions.
. When the engine speed reaches the
level that was previously set, the REV
indicator light illuminates to inform you. At
this time, a buzzer also sounds if the
buzzer setting is activated.
. Whenever the engine speed enters the
red zone of the tachometer, the REV
indicator light flashes.

NOTE
Even if the REV alarm system is not set,
the REV indicator light will flash when-

ever the engine speed enters the red
zone of the tachometer.
To change the REV indicator settings,
perform the procedures described in “REV
settings (STI)” F3-44.
