From FSM:

"SYSTEM DESCRIPTION
Refer to Owner's Manual for SynchroRev Match mode (S-MODE) operating instructions.
SynchroRev Match mode (S-MODE) controls engine speed at a suitable level from the present to the next
gear position. This control is switched by S-MODE switch (Refer to EC-531, "
Description"). When clutch pedal
is depressed and shift lever is shifted while S-MODE is being operated, gear position signal is sent to ECM.
ECM calculates target engine speed by gear position signal and vehicle speed signal, and then controls throttle
opening angle and ignition
timing. When downshift
is performed,
even if
accelerator
pedal is not depressed,
ECM
automatically controls throttle
opening angle and
increases engine
speed. When upshift
is
performed,
ECM
controls engine speed so
that it does
not drop lower
than the necessary level that is required
after
upshifting.
Engine
speed is controlled
according
to shifting
operation above
and
driver can perform shifting
operation
quickly,
smoothly,
and without shifting
shock.
When S-MODE
malfunction is
detected, S-MODE
warning
on information display illuminates
and S-MODE is automatically
cancelled.
At this
time, S-MODE indicator
turns OFF."
