FORD 2001 F-550 v.1 - Manual (Page 12)

Transmission control indicator light (TCIL)
Illuminates when the Transmission
Control Switch (TCS), refer to
Overdrive control in the Controls
and Features chapter, has been
pushed turning the transmission
overdrive function OFF. When the TCIL (the word OFF on the gear shift)
light is on, the transmission does not operate in the overdrive mode, refer
to the Driving chapter for transmission function and operation.
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.
Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
the Seating and safety restraints chapter.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
to indicate a system check. Also
illuminates if the parking brake is
engaged. If the brake warning lamp
does not illuminate at these times, seek service immediately. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
to indicate a system check. If the
light remains on, continues to flash
or fails to illuminate, have the
system serviced immediately. With the ABS light on, the anti-lock brake
system is disabled and normal braking is still effective unless the brake
warning light also remains illuminated with the parking brake released.
