04 SIENNA_U (L/O 0408) 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. Before driving in the vehicle- to- vehicle distance control mode, make sure the radar sensor glass is clean. This product is a class I laser product complied with 21 C.F.R part 1040.10 and 1040.11. 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 206.) However, if the glass sensor is covered with icicle or any substance, dirt may not be detected. CAUTION To ensure that dynamic laser cruise control will function properly while driving, observe the following: D Always keep the laser radar sensor glass clean. When cleaning, use a soft cloth and be careful not to damage the sensor. D Avoid strong impacts around the laser radar sensor. An incorrect laser radar sensor alignment will result in system malfunction. A special device is required to adjust the laser radar sensor alignment. Be sure to have the sensor adjusted by your Toyota dealer. D Do not affix a sticker (including a transparent sticker) or attach an accessory around the laser radar sensor. 205 2004 SIENNA from Aug.
