2-4. Using other driving systems Example of follow-up cruising When following a vehicle driving slower than the set speed The system continues follow-up cruising while adjusting for changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver. Example of acceleration When there are no longer any vehicles ahead driving slower than the set speed The system accelerates until the set speed is reached. The system then returns to constant speed cruising. 2 When driving Approach warning When your vehicle is too close to a vehicle ahead, and sufficient automatic deceleration via the cruise control is not possible, the display will flash and the buzzer will sound to alert the driver. An example of this would be if another driver cuts in front of you while you are following a vehicle. Apply the brakes to ensure an appropriate vehicle-to-vehicle distance. 211
