To assist with directional control of the vehicle, always leave the system on. Stability control can be turned off however, by using the TC button. See Traction Control System (TCS) on page 5‑9. The STABILITY SYS OFF message will be displayed on the DIC. See DIC Warnings and Messages on page 4‑76. If there is a problem detected with Enhanced StabiliTrak, the SERVICE STABILITY SYS message will be displayed on the DIC. See DIC Warnings and Messages on page 4‑76. When this message is displayed, the system is not operating. Driving should be adjusted accordingly. When certain faults or vehicle conditions are detected, the Stability control will automatically go into a secure mode and the STABILITY SECURE MODE message will be displayed on the DIC. When the Stability Secure Mode is activated, the stability control system will not respond to driver requests to change the stability mode until the next ignition cycle or until the vehicle condition or fault is returned to normal. When the Stability Secure Mode is activated, other messages may be displayed, such as SERVICE STEERING SYS, SERVICE SUSPENSION SYS or CHECK TIRE PRESSURE on the DIC. When the Stability Secure Mode is activated, a larger degree of steering wheel input at low vehicle speeds and a smaller degree of steering wheel input at high vehicle speeds may be required. Stability Secure Mode will be activated if a compact spare tire is being used. See DIC Warnings and Messages on page 4‑76 and Compact Spare Tire on page 6‑107. Persistent operation of the vehicle in the STABILITY SECURE MODE may be an indication that the vehicle needs to be serviced by your dealer/retailer. When certain faults are present, the vehicle's speed may be limited and the SPEED LIMITED TO XXX message will be displayed on the DIC. See DIC Warnings and Messages on page 4‑76. When the vehicle's speed is limited, other messages may be displayed, such as SERVICE STABILITY SYS, SERVICE STEERING SYS or SERVICE SUSPENSION SYS on the DIC. Have the vehicle serviced by your dealer/retailer. 5-8
