FORD 2013 E-450 v.2 - Manual (Page 142)

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL (IF EQUIPPED)
In certain situations (for example, stuck in snow or mud), turning the
traction control off may be beneficial as this allows the wheels to spin
with full engine power. Turn the traction control system off using the
TCS OFF button located on the instrument panel .
System indicator lights and messages
WARNING: If a failure has been detected within the Traction
Control System, the stability control light will illuminate steadily.
Verify that the Traction Control System was not manually disabled. If
the stability control light still illuminates steadily, have the system
serviced by an authorized dealer immediately. Operating your vehicle
with Traction Control disabled could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury and death.
The stability control light temporarily illuminates on engine
start-up and flashes when a driving condition activates the
stability system.
The stability control off light temporarily illuminates on engine
start-up and stays on when the traction control system is
turned off or if a problem occurs in the stability system.
When the traction control system is turned off or on, a message appears
in the information display showing system status.
