"Stability/Traction Control Switch
The stability/traction control switch can be used by the driver to disable and enable the traction control, ESC and RSC® systems. When the ignition key is turned to the RUN position, all 3 systems are enabled and the sliding-car icon in the IC will illuminate momentarily as a test. Momentarily pressing the switch will only disable the traction control system. Pressing and holding the switch for more than 5 seconds (with a vehicle speed less than 56 km/h [35 mph]) will disable all 3 systems. When all 3 systems are disabled, the sliding car OFF icon in the IC will extinguish for 3 seconds before illuminating solidly.
There are 2 separate sliding car icons; the sliding car OFF icon and the sliding car icon. The sliding car OFF icon is used to alert the driver that the traction control portion of the AdvanceTrac® system has been disabled by the driver. This icon will only illuminate solidly and does not flash. The sliding car icon is used to alert the driver that a stability/traction event is taking place (flashes twice per second) and to alert the driver of potential concerns in the AdvanceTrac® system (illuminates solidly).
On vehicles equipped with Four-Wheel Drive (4WD), the sliding car OFF icon will turn on and all 3 systems will be disabled when the 4WD Low Locked transfer case mode is selected. Additionally, if one or more of the vehicle dynamic systems has been disabled through the use of the switch and the driver shifts the transfer case into 4WD HI or 2-Wheel Drive (2WD), all disabled systems will be enabled.
If all 3 systems have been disabled by the driver through the use of the switch as described above and the vehicle exceeds 56 km/h (35 mph), the AdvanceTrac® system will enable the ESC and RSC® systems, but the traction control system will remain disabled and the sliding car icon will remain illuminated until the switch is pressed again, or the ignition key is cycled to the OFF position and back to the RUN position.
The conventional ABS system cannot be disabled through the use of the stability/traction control switch."
