FORD 2009 Explorer Sport Trac v.2 - Manual (Page 237)

• If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
• The brake pedal may feel stiffer than usual.
Traction Control (TCS)
Traction Control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: Engine Traction Control and Brake Traction
Control. Engine Traction Control works to limit drive-wheel spin by
momentarily reducing engine power. Brake Traction Control works to
limit wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction Control is most active at low speeds.
During Traction Control events the “sliding car” icon in the
instrument cluster will flash.
If the Traction Control system 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, Traction
Control 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, RSC
௡, and ESC are not
affected by this condition and will continue to function during the
cool-down period.
The Engine Traction Control and Brake Traction Control system may be
deactivated in certain situations. See the Switching Off AdvanceTrac
௡
with RSC
௡ section following.
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 Electronic Stability Control events the “sliding car” icon in the
instrument cluster will flash.
