08 SIENNA_U (L/O 0801) Dynamic laser cruise control should not be used in circumstances which are inappropriate for any cruise control, such as entering free way on−ramps or off −ramps. D If other vehicles are driving outside of the laser radar detection range, a delay in the detection of the vehicle cutting in at short range or failure to detect a motorcycle running on the side of the same lane will occur. In this case, the dynamic laser cruise control system will not function properly. TURNING THE SYSTEM ON AND OFF To turn the dynamic laser cruise control on, turn the "ON−OFF" button on. The "CRUISE" and "READY" indicator lights on the instrument panel will come on to indicate that the vehicle−to−vehicle distance control mode is operational. Pressing the "ON−OFF" button again turns the system off. When the system is turned off, cruising speed and vehicle−to−vehicle distance must be reset when the vehicle−to−vehicle distance control mode is turned on again. CAUTION D Do not use dynamic laser cruise control when exiting from or when entering or merging onto a freeway. When you are following a slower moving vehicle and exiting, the sensor does not detect the vehicle and will accelerate to the preset speed. D When a slower vehicle in front of you leaves the lane, the dynamic laser cruise control will no longer detect a vehicle ahead and will attempt to accelerate the vehicle to the faster preset speed. 230 2008 SIENNA from Aug.
