2005 Lexus RX 330 Owners Manual - Page 453

STARTING AND DRIVING D Deceleration cruising function and approach warning do not operate when the vehicle ahead is at a stop or driving very slowly. D If the vehicle ahead of you decelerates abruptly or if another vehicle cuts in ahead of you, your vehicle may collide with the vehicle ahead unless you manually depress the brake pedal to slow down your vehicle. D Depending on the road configuration (curved, left and right continuous curved, the start or end of a curve, or narrow driving lanes due to road construction) or your vehicle condition (steering wheel maneuvering, position in the lane, or unstable driving because of an accident or breakdown), vehicles in other lanes or surrounding objects may be detected, resulting in a control failure or the approach warning activation. This may also result in a very close distance between vehicles due to a failure to detect the vehicle ahead. 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. 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. 422
