1)

REV indicator light and buzzer (STI)

Normal operating range

The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON” position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.

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.
If you press the trip knob, the odometer/
trip meter will show the engine speed that
has already been set.
