Behavior in curves Driver interventions and your responsibility Anytime the driver presses down on the accelerator pedal, any automatic braking action by the system is interrupted and the distance indicator turns off until the pedal is fully released. As soon as you fully release the accelerator, the system will once again control your cruising speed and distance setting. While driving with the system activated, resting your foot on the accelerator pedal will cause the system not to brake even if necessary. Be certain that floormats or other objects on the vehicle floor do not interfere with movement of the accelerator pedal.< While active cruise control is capable of braking your vehicle automatically when you approach a slower vehicle ahead, it is important to be aware that the ability of the system to apply the brakes is also limited, e.g. when you reduce your desired speed sharply. It uses only a portion of braking system capacity and does not utilize the full capacity of the vehicle braking system. Therefore, the system cannot decrease your speed due to large differences in speed between your vehicle and the vehicle ahead. Example: when you approach a vehicle traveling at a much lower speed than your own speed such as approaching a toll booth or when a much slower vehicle cuts in front of you at close range.< In approaching a curve, it is possible that active cruise control might react briefly to a vehicle in the adjacent lane. In addition, the system can sense if your vehicle is in a curve and may not accelerate. If your vehicle decelerates in either case, you can choose to overcome the deceleration by briefly pressing the accelerator pedal. 73 Online Edition for Part no. 01 41 0 014 242 - © 08/07 BMW AG Reference Mobility Communications Entertainment Navigation Because of the limited range of the system, it is possible that in curves or on the peaks and valleys of hilly roads, a vehicle ahead may be recognized late, or not at all. Therefore, it is up to the driver to select a speed that is prudent in view of the curves and terrain of the roadway. Driving tips If the selected desired speed for a curve is too high, the system reduces the speed within a curve. However, it cannot detect curves in advance. Therefore, select a suitable speed at the start of a curve. Controls At a glance
