warning FORD MUSTANG 2021 Workshop Manual

If it flashes, engine misfire may be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Drive in a moderate fashion (avoid heavy
acceleration and deceleration) and have
your vehicle immediately serviced.
It illuminates when you switch the ignition
on prior to engine start to check the bulb
and to indicate whether your vehicle is
ready for Inspection and Maintenance
(I/M) testing.
Normally, it illuminates until the engine is
cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.
See Catalytic Converter (page 161).
Shift Indicator
(If Equipped) Illuminates to inform you that
shifting to a higher gear as
indicated may give better fuel
economy and lower CO2
emissions. It will not illuminate during
periods of high acceleration, braking or
when you press the clutch pedal.
Stability Control and Traction
Control Indicator Flashes during operation.
If it does not illuminate when you
switch the ignition on, or remains
on when the engine is running, this
indicates a malfunction. Have your vehicle
checked as soon as possible.
Note: The system automatically turns off
if there is a malfunction.
See
Using Stability Control (page 176).
See Using Traction Control (page 174). Stability Control and Traction
Control Off Warning Lamp Illuminates when you switch the
system off.
Trunk Ajar Illuminates when the ignition is
on and the trunk is not
completely closed.
