On highways or expressways, Dynamic Radar Cruise Control (9) functions similar to conventional “constant speed” cruise control in that it helps vehicles travel at a consistent speed set by the driver, but this system adds a vehicle-to-vehicle distance control mode, which assists the driver by adjusting vehicle speed (within a set range) to help maintain a preset distance to a preceding vehicle when the preceding vehicle is traveling at a lower speed.

Once a vehicle speed is set by the driver, Dynamic Radar Cruise Control (9) uses a grille-mounted millimeter-wave radar and an in-vehicle camera to detect a preceding vehicle and help determine its distance. If the vehicle ahead is detected traveling at a speed slower than your set speed or within your distance range setting, the system is designed to automatically decelerate your vehicle without having to cancel the cruise control. When a greater reduction in vehicle speed is necessary, the system may apply the brakes and operate your vehicle brake lights. The system will then respond to changes in the speed of the vehicle ahead in order to help maintain the vehicle-to-vehicle distance set by the driver. When there is no longer a preceding vehicle driving slower than your vehicle’s set speed, the system accelerates until the set speed is reached and returns to constant speed cruising.

As there is a limit to the degree of recognition accuracy and distance/deceleration control performance that this system can provide, do not overly rely on this system. This system will not operate in every situation. In some situations, such as when driving in inclement weather such as heavy rain, fog, snow or a sandstorm, or while driving on a curve and for a few seconds after driving on a curve, a preceding vehicle may not be detected by the camera/radar sensors, preventing the system from operating or engaging properly.

Dynamic Radar Cruise Control (9) is designed to function at speeds of approximately 25 to 110 MPH. However, vehicle speed must be above approximately 28 MPH to initiate Dynamic Radar Cruise Control (9) as that is the lowest set speed.

The following setting(s) can be adjusted:

• Vehicle-to-vehicle distance settings, or distance between your vehicle and the preceding vehicle: Long – Medium (default) – Short.

Refer to a Lexus Owner’s Manual for additional information on Dynamic Radar Cruise Control (9) operation, setting adjustments,limitations and precautions.
