Overdrive Off Indicator Light
This light illuminates when the OVERDRIVE OFF/ON button on
the gearshift selector lever has been pushed. When the light is
on, the transmission does not shift into overdrive. Depressing the
button on the shifter once more allows the vehicle to shift into
overdrive mode. This light also briefly illuminates when the key is
turned to the ON position.

If the light flashes for about 8 seconds when the ignition is turned
to ON, it means the transaxle control module received an
improper signal the last time the vehicle was operated. It may be
necessary to have your dealer check the transaxle.
