Introduction
Adaptive Cruise Control (ACC) is an optional system designed to assist the driver by main-taining a set speed or a set time interval tothe vehicle ahead. It is primarily intended foruse 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:
• If there are no other vehicles in the lane ahead of you, your vehicle will travel atthe set speed.
• If ACC's radar sensor detects a slowermoving vehicle in the lane ahead, the sys-tem will adapt your vehicle's speed tohelp maintain the set time interval to thevehicle ahead. When there are no longerslower moving vehicles ahead, your vehi-cle will accelerate to resume the setspeed.
If ACC is switched off completely or in standby mode and your vehicle comes tooclose to another vehicle ahead, the driver willbe warned by the Distance Alert system (seepage 161).WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic,weather and road conditions. The"Function" section provides informa-tion about limitations that the drivermust be aware of before using thisfeature.
• This system is designed to be a sup-plementary driving aid. It is not, how-ever, intended to replace the driver'sattention and judgement. The driver isresponsible for maintaining a safe dis-tance and speed and must intervene ifAdaptive Cruise Control does notmaintain a suitable speed or suitabledistance to the vehicle ahead.
• Maintenance of ACC components mayonly be performed by a trained andqualified Volvo technician.
