fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.
Transmission control indicator light (TCIL)
Illuminates when the Transmission
Control Switch (TCS), refer to
Overdrive control in the Controls
and Features chapter, has been

The light may also flash steadily if a transmission malfunction is
detected. If the light does not come on when the Transmission Control
Switch is depressed or if the light flashes steadily, have your vehicle
serviced as soon as possible, damage to the transmission could occur.

system should be inspected immediately.
