05 SIENNA_U (L/O 0409) Braking control is operating only when the vehicle−to−vehicle distance control mode is selected and your vehicle speed exceeds about 40 km/h (25 mph). If the speed decreases below about 40 km/h (25 mph), braking control will cease, requiring the manual application of brakes. CAUTION D If the display flashes and beeps, you must depress the brake pedal to slow down to avoid a collision or maintain sufficient vehicle−to−vehicle distance. CAUTION Braking control will not ensure that your vehicle will reduce speed appropriately. You must depress the brake pedal to slow down, ensuring collision avoidance or that sufficient vehicle−to−vehicle distance is maintained. 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, inadequate braking will make your vehicle become closer to the vehicle ahead of you and the display will flash and beep. 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. LASER RADAR SENSOR The laser radar sensor is used for vehicle−to−vehicle distance control cruising. If dirt is on the sensor glass, the dynamic laser cruise control function is automatically cancelled and a warning code appears on the display. (See "VEHICLE−TO−VEHICLE DISTANCE CONTROL MODE FAILURE WARNING" on page 214.) However, if the glass sensor is covered with icicle or any substance, dirt may not be detected. 213 2005 SIENNA from Sep.
