Ford 2011 F-250 Automobile User Manual


 
The AdvanceTrac with RSC
system includes a stability control
button located on the instrument
panel to the right of the climate
control system, a stability control
light and a stability control off light
in the instrument cluster. Both
lights will illuminate temporarily during start-up as part of a normal
system self-check. The stability control light may illuminate (flash)
during certain driving situations which cause the AdvanceTrac with
RSC system to operate. If the stability control light and stability control
off light illuminate steadily, have the system serviced by an authorized
dealer immediately. The message center will also indicate a failure with
the AdvanceTrac with RSC system.
Note: If the system cannot be turned off, refer to MyKey™ in the Locks
and Security chapter for more information.
When AdvanceTrac with RSC performs a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac with RSC you may
experience the following:
A slight deceleration of the vehicle
The stability control light will flash.
A vibration in the pedal when your foot is on the brake pedal
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 system (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.
