STARTING AND DRIVING (k) Laser radar sensor 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 Lexus dealer. 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 message "CLEAN RADAR SENSOR" appears on the display. (See "(l) Vehicle−to−vehicle distance control mode failure warning" on page 436.) However, if the glass sensor is covered with ice or another transparent substance, dirt may not be detected. Before using the vehicle−to−vehicle distance control mode, make sure the laser 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 Do not affix a sticker (including a transparent sticker) or attach an accessory around the laser radar sensor. 435
