04 Comfort and driving pleasure Adaptive Cruise Control (ACC)* Introduction Adaptive Cruise Control (ACC) is an optional system designed to assist the driver by maintaining a set speed or a set time interval to the vehicle ahead. It is primarily intended for use on long straight roads in steady traffic, such as on highways and other main roads. When the driver has set the desired speed and the time interval to the vehicle ahead, ACC functions as follows: WARNING Function • Adaptive Cruise Control cannot cover all driving situations and traffic, weather and road conditions. The "Function" section provides information about limitations that the driver must be aware of before using this feature. This system is designed to be a supplementary driving aid. It is not, however, intended to replace the driver's attention and judgement. The driver is responsible for maintaining a safe distance and speed and must intervene if Adaptive Cruise Control does not maintain a suitable speed or suitable distance to the vehicle ahead. Maintenance of ACC components may only be performed by a trained and qualified Volvo technician. • • If there are no other vehicles in the lane ahead of you, your vehicle will travel at the set speed. Function overview • If ACC's radar sensor detects a slower moving vehicle in the lane ahead, the system will adapt your vehicle's speed to help maintain the set time interval to the vehicle ahead. When there are no longer slower moving vehicles ahead, your vehicle will accelerate to resume the set speed. If ACC is switched off completely or in standby mode and your vehicle comes too close to another vehicle ahead, the driver will be warned by the Distance Alert system (see page 170). Warning light, braking by driver required Controls in steering wheel Radar sensor in front grille Adaptive Cruise Control consists of: • • A cruise control system to maintain a set speed • A system to maintain a set distance to the vehicle ahead, which is expressed as a time interval. For example, you can choose to remain approximately 2 seconds behind the vehicle ahead. The actual distance required to maintain a 2-second interval will vary according the speed of the vehicles.
