FORD 2011 Fiesta v.2 - Manual (Page 241)

WARNING: If a failure has been detected within the
AdvanceTrac
௡ system, the stability control light will illuminate
steadily. Have the system serviced by an authorized dealer immediately.
The AdvanceTrac
௡ system automatically enables each time the engine is
started. All features of the AdvanceTrac
௡ system (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.
The AdvanceTrac
௡ system includes a stability control light in the
instrument cluster. The stability control light in the instrument cluster
will illuminate temporarily during start-up as part of a normal system
self-check, or during driving if a driving situation causes the
AdvanceTrac
௡ system to operate. If the stability control light illuminates
steadily, have the system serviced by an authorized dealer immediately.
When AdvanceTrac
௡ 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
௡, 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.
During TCS events, the stability control light in the instrument cluster
will flash.
