system inspected by your dealer/retailer as soon as possible. See StabiliTrak® System on page 5‑6 or Enhanced StabiliTrak® on page 5‑7 for more information. For vehicles with the Active Steering with Enhanced StabiliTrak option, in some cases when the SERVICE STABILITY SYS message is displayed, a larger degree of steering wheel input at low vehicle speeds and a smaller degree of steering wheel input at higher vehicle speeds may be required. If the SERVICE STEERING SYS message appears because the Active Steering system needs service, normal power steering is still operational. However, compared to Active Steering, normal power steering requires a larger degree of steering wheel input at low vehicle speeds and a smaller degree of steering wheel input at high vehicle speeds. The center position of the steering wheel may be different. You may continue to drive your vehicle with normal power steering, but have the steering system inspected by your dealer/retailer as soon as possible. If the Active Steering system needs service, the system may be operating in the Stability Secure Mode and the STABILITY SECURE MODE message will display. See Enhanced StabiliTrak® on page 5‑7. When certain steering faults are present, the vehicle speed may be limited. If vehicle speed is limited, the SPEED LIMITED TO XXX message will display. See "Active Steering" under Steering on page 5‑11. SERVICE STEERING SYS (System) Your vehicle has a speed variable assist steering system. Your All-Wheel Drive (AWD) vehicle may have the Active Steering with Enhanced StabiliTrak option. See "Active Steering" under Steering on page 5‑11. This message displays if a problem is detected with the speed variable assist steering system or the Active Steering system. When this message is displayed, you may notice that the effort required to steer the vehicle increases or feels heavier, but you will still be able to steer the vehicle. See Steering on page 5‑11 for more information. Have the steering system inspected by your dealer/retailer as soon as possible. 4-87
