{ WARNING: . WARNING: (Continued) . On winding roads, Adaptive Cruise Control may not detect a vehicle ahead. You could crash into a vehicle ahead of you. Do not use Adaptive Cruise Control on winding roads. Adaptive Cruise Control may not have time to slow your vehicle enough to avoid a crash when you are driving in conditions where vehicles may suddenly slow or stop ahead of you, enter your lane, or cross your vehicle's path. If you are driving in these conditions, do not use Adaptive Cruise Control. The warning beep and alert symbol may indicate that you are driving in conditions where Adaptive Cruise Control should not be used. See "Alerting the Driver" in this section. On slippery roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads. (Continued) . When weather limits visibility, such as when in fog, rain, or snow conditions, Adaptive Cruise Control performance is limited. There may not be enough distance to adapt to the changing traffic conditions. Do not use cruise control when visibility is low. . The ACCs are located on the steering wheel.
