FORD 2013 Expedition v.1 - Manual (Page 228)

PRINCIPLES OF OPERATION
WARNING: Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction or wheel/tire size may change the handling characteristics
of the 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’s 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
௡ with Roll Stability Control™ (RSC௡) system helps
you keep control of your vehicle when on a slippery surface. The
electronic stability control (ESC) portion of the system helps avoid skids
and lateral slides and roll stability control helps avoid a vehicle rollover.
The traction control system (TCS) helps avoid drive wheel spin and loss
of traction. For details on TCS operation, see the Traction Control
chapter.
