FORD 2011 Focus v.2 - Manual (Page 180)

The AdvanceTrac
௡ system includes
a stability control button on the
center of the instrument panel, and
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, verify that the AdvanceTrac
௡ system is not manually disabled by
pressing the stability control button located on the center stack of the
instrument panel. If the stability control light remains steadily
illuminated, have the system serviced by an authorized dealer
immediately. If equipped with a message center, the vehicle will also
indicate a failure with the AdvanceTrac
௡ system.
Note: If the system cannot be turned off, refer to MyKey™ in the Locks
and Security chapter for more information.
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.
