FORD 2013 Flex v.4 - Manual (Page 221)

PRINCIPLES OF OPERATION
WARNING: Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and wheel or tire size may change the handling
characteristics of your vehicle and may adversely affect the performance
of the AdvanceTrac® system. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac®
system. Install any aftermarket stereo loudspeaker as far as possible from
the front center console, the tunnel, and the front seats in order to
minimize the risk of interfering with the AdvanceTrac® sensors. Reducing
the effectiveness of the AdvanceTrac® system could lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING: Remember that even advanced technology cannot
defy the laws of physics. It is always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTrac® system is an indication that at least
some of the tires have exceeded their ability to grip the road; this could
reduce the operator’s ability to control the vehicle potentially resulting
in a loss of vehicle control, vehicle rollover, personal injury and death.
If your AdvanceTrac® system activates, SLOW DOWN.
The AdvanceTrac® system helps you keep control of your vehicle when
on a slippery surface. The electronic stability control portion of the
system helps avoid skids and lateral slides and the traction control
system helps avoid drive wheel spin and loss of traction. See the
Traction Control chapter for details on traction control system
operation.
