STARTING AND DRIVING CAUTION Braking control will not ensure that your vehicle will reduce speed appropriately. You must depress the brake pedal to slow down, in order to avoid a collision or to maintain sufficient vehicle−to−vehicle distance. (j) Approach warning While you are cruising in the vehicle−to−vehicle distance control mode, if the vehicle ahead decelerates abruptly or if another vehicle cuts in ahead of you, your vehicle may come closer to the vehicle ahead. The display will flash and beep to alert you. CAUTION D If the display flashes and beeps, this indicates that you must depress the brake pedal in order to slow down sufficiently to avoid a collision or maintain appropriate vehicle−to−vehicle distance. D In the following conditions, the approach warning may not turn on even if the vehicle drives closer to the vehicle ahead, and an accident may occur: 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.) The vehicle ahead is at a stop or driving very slowly. Pay special attention to a very slow vehicle at the end of the line in heavy traffic or at a tollgate. The speed has just been set. The accelerator pedal is depressed or has just been released. 434
