REV indicator light and buzzer (STI)

Normal opera ting 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 issues a warning
using the REV indicator light (and a
buzzer if additionally selected) when the
engine speed reaches a level previously
set using the trip knob.
If you press the trip knob, the odometer/
trip meter will show the engine speed that
has already been set.
