STARTING AND DRIVING The dynamic laser cruise control function operates automatically and depending on whether a vehicle is detected ahead may change the speed of your vehicle as follows. If no vehicle is running ahead of you - 1 If a vehicle is detected ahead of you - 2 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 display. For the vehicle speed setting, see "(c) Setting the desired speed" on page 424. 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 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 alarm 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 "(h) Changing vehicle−to−vehicle distance" on page 427. 3 419
