STARTING AND DRIVING The vehicle−to−vehicle distance is always set to "Long" when the engine switch is turned on. (e) Braking control Dynamic radar cruise control is not a collision avoidance system. If an approach warning is activated, depress the brake pedal to decelerate to ensure an appropriate vehicle−to−vehicle distance. CAUTION D Select the vehicle−to−vehicle distance considering traffic conditions. The approximate vehicle−to−vehicle distance based on time interval when driving at 80 km/h (50 mph) is shown below : "Long" ...about 50 m (about 164 ft.) "Middle" ...about 40 m (about 132 ft.) "Short" ...about 30 m (about 100 ft.) If the vehicle speed is slower than 80 km/h (50 mph), the distance will be shorter than the above. D During long downhill driving, the vehicle−to−vehicle distance will be shorter than the selected distance. G31017 " 1 Under the vehicle−to−vehicle distance control 2 Braking activated Braking control is operating only when the vehicle−to−vehicle distance control mode is selected and your vehicle speed exceeds about 40 km/h (25 mph). If you are getting closer to the vehicle ahead at relatively higher speed than those of the vehicle ahead or if engine braking cannot be applied properly, braking control is automatically activated. At this time, "BRAKE" flashes on the multi−information display, indicating that the brakes are being used. 413
