STARTING AND DRIVING If no vehicle is running ahead of you: 1 Cruising at a fixed speed: If there is no vehicle detected ahead, your cruising speed is maintained at the preset speed from about 45 km/h (28 mph) to about 135 km/h (85 mph). The preset speed is displayed in the multi−information display. For the vehicle speed setting, see "Setting operation " on page 341. Deceleration cruising function: If a slower moving vehicle is detected ahead of you, your vehicle cruising speed decreases within the range of about 40 km/h (25 mph) to about 135 km/h (85 mph). The multi−information display shows the preset speed, the detected vehicle ahead and selected vehicle−to−vehicle distance. If your vehicle gets closer to the vehicle ahead because of insufficient automatic deceleration, then the warning tone warns you to also manually apply brakes. Follow−up cruising function: After deceleration, your vehicle cruising speed changes in proportion to the speed of the vehicle ahead to maintain an appropriate distance from your vehicle to the vehicle ahead. The vehicle−to−vehicle distance can be changed. For details, see "Changing vehicle−to−vehicle distance setting" on page 347. Acceleration cruising function: If the vehicle ahead changes lanes, your vehicle cruising speed will be gradually increased up to the preset speed, and your vehicle resumes fixed−speed cruising. CAUTION Under certain conditions where the vehicle in front slows drastically, or is stopped, the dynamic radar/laser cruise control will neither warn you nor decelerate. The driver must depress the brake pedal to slow down, ensuring collision avoidance or that sufficient vehicle−to−vehicle distance is maintained. When vehicle−to−vehicle distance control mode is activated, you must still be attentive to road and traffic conditions. Should your vehicle speed decrease below about 40 km/h (25 mph), the dynamic radar/laser cruise control will shut off, requiring you to apply the brakes to slow. When a vehicle ahead slows suddenly, stops or a vehicle cuts in front, the system may slow your vehicle abruptly, but the automatic braking will cease if the speed decreases below about 40 km/h (25 mph) requiring the driver's manual application of brakes.
