2020 FORD F-350 warning

Powertrain Malfunction/Reduced
Power/Electronic Throttle Control
Illuminates when a powertrain
or a 4WD fault has been
detected. Have your vehicle
checked as soon as possible.
Service Engine Soon 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 Emission Law (page 188).
If it illuminates when the engine is running
this indicates a malfunction. The On Board
Diagnostics system has detected a
malfunction of the vehicle emission control
system.
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 checked immediately.
Stability Control Illuminates when the system is
active. If it remains illuminated
or does not illuminate when you
switch the ignition on, this indicates a
malfunction. During a malfunction, the
system switches off. Have the system
checked immediately. See
Using
Stability Control (page 223). Stability Control Off Illuminates when you switch the
system off. It goes out when you
switch the system back on or
when you switch the ignition off.
See Using Stability Control (page 223).
Tailgate Ajar Illuminates when the tailgate is
not completely closed or when
opened and then closed when
the transmission is in any gear other than
park (P).
Transmission Tow/Haul
(If Equipped) Illuminates when the tow/haul
feature is activated. If the light
flashes steadily, have the system
checked immediately as damage to the
transmission could occur.
Wait To Start
(If Equipped) Illuminates when you switch the
ignition on as part of the
pre-start system. Wait until the
wait to start indicator turns off before
attempting to start your vehicle. See
Starting a Diesel Engine
(page 171).
Water In Fuel
(If Equipped) WARNING:
Do not drain the
water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage.

During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator illuminates
when the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 179).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.
Four-Wheel Drive Indicators
