I went on a drive today to another town, ~120km away. I had considerable difficulty getting SCC to engage; I kept getting a warning chime and a circle with a line through it icon displaying when trying to turn cruise on. The message displayed was "Smart Cruise Ctrl Conditions Not Met". I was going 95km/h+, would press "Cruise", then the down button for "Set" and this would happen, over and over. Roads were bare and dry, relatively flat, lane lines clearly visible (and acknowledged by the car - ALKA worked fine). Sometimes a car was in front of me when trying, sometimes not. I tried again about 10 minutes later and it worked right away. Then on the trip back the same problem occurred. I looked in the manual quickly and didn't see this error mentioned in the smart cruise control section. Anyone else encounter this? Any thoughts on the problem?
