2-4. Using other driving systems Driving in vehicle-to-vehicle distance control mode This mode employs a laser radar sensor to detect the presence of vehicles within 400 ft. (120 m) ahead and to judge the distance between your vehicle and those vehicles. Note that vehicle-to-vehicle distance will close when traveling on long downhill slopes. 2 When driving Example of constant speed cruising (when there are no vehicles ahead): When set to 62 mph (100 km/h) The vehicle travels at the speed set by the driver. The desired vehicle-tovehicle distance can also be set by operating the vehicle-to-vehicle distance switch. Example of deceleration cruising (when the vehicle ahead is driving slower than the set speed): When fixed speed cruising is set at 62 mph (100 km/h) and the vehicle ahead is driving at 50 mph (80 km/h) When a vehicle is detected running ahead of you, in the same lane, the system automatically decelerates your vehicle. When a greater reduction in vehicle speed is necessary, the system applies the brakes. A warning tone warns you when the system cannot decelerate sufficiently to prevent your vehicle from closing on the vehicle ahead. 189
