06 SIENNA_U (L/O 0603) 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. If "E1" appears on the display, the system cannot easily measure the vehicle- tovehicle distance because of a dirty laser radar sensor glass while the dynamic laser cruise control is on. If this code appears, clean the sensor glass with a soft cloth and try setting the preset speed again. If the dirt is removed without cleaning, the system will automatically enter the ready mode. If the system does not enter the ready mode even after cleaning or the code remains on the display, the system might be malfunctioning. Although there is no problem to continue driving, please contact your Toyota dealer. 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. VEHICLE- TO- VEHICLE DISTANCE CONTROL MODE FAILURE WARNING If there is trouble somewhere in the dynamic laser cruise control while the vehicle- to- vehicle distance control mode is on, the master warning light comes on and the alarm sounds, and one of the warning codes "E1", "E2" or "E3" will appear on the display. Dynamic laser cruise control is automatically cancelled. If "E3" appears on the display, the "CRUISE" indicator light in the instrument cluster also flashes. CAUTION Always keep the sensor glass and never allow it to be covered with icicle or any substance, so it can detect the vehicle in front. 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. 227 2006 SIENNA from March '06 Prod. (OM45443U)
