Electronic Stability Control (Esc); Switching Off Advancetrac - Ford Fusion Hybrid Owner's Manual

Driving
If TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, TCS will use only engine power
reduction or transfer to help control the wheels from over-spinning.
When the brakes have cooled down, the system will regain all features.
Anti-lock braking and Electronic stability control (ESC) will continue to
function during the cool-down period.
The engine traction control and brake traction control systems may be
deactivated in certain situations. See the Switching off AdvanceTrac
section below.

Electronic stability control (ESC)

Electronic stability control (ESC) may enhance your vehicle's directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During ESC events, the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate ESC, which include but
are not limited to:
• Taking a turn too fast
• Maneuvering quickly to avoid an accident, pedestrian or obstacle
• Driving over a patch of ice or other slippery surfaces
• Changing lanes on a snow-rutted road
• Entering a snow-free road from a snow-covered side street, or vice
versa
• Entering a paved road from a gravel road, or vice versa

Switching off AdvanceTrac

If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac system may be
beneficial because the wheels are allowed to spin. This will restore full
engine power and will enhance momentum through the obstacle.
To switch off the traction control
system, press the stability control
switch. Full features of the
AdvanceTrac system can be
restored by pressing the stability control switch again or by turning off
and restarting the engine.
