The approach warning may not turn on even if the
vehicle drives closer to the vehicle ahead in the
following conditions:
♦ Your vehicle and the vehicle ahead are cruising at
almost the same speed.
♦ The vehicle ahead is cruising at a faster speed than
yours. (The distance between the vehicles will
become longer.)
♦ Pay special attention to the very slow vehicle at the
end of the line in heavy traffic or at the tollgate.
♦ Immediately after the speed setting.
♦ The accelerator pedal is depressed or immediately
after the release of the accelerator pedal.
