FORD 2013 Fusion Hybrid v.1 - Manual (Page 184)

PRINCIPLE 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
In certain situations (e.g. 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 off the
traction control system through the
information display. See General
Information (page 84).

WARNING
If a failure has been detected within
the AdvanceTrac system, the
stability control light will illuminate
steadily. Verify that the AdvanceTrac
system was not manually disabled through
the information display. If the stability
control light still illuminates steadily, have
the system serviced by an authorized
dealer immediately. Operating your vehicle
with AdvanceTrac disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
