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
distance 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.
WARNING
Do not use the adaptive cruise control system in demanding driving conditions such as city traffic, winding roads,
at intersections, on slippery surfaces, in poor visibility, heavy rain, etc.
Maintenance of cruise control components must only be performed by an authorized Volvo workshop.
WARNING
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 the adaptive cruise
control.
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.
Function
Warning light, braking by driver required
Controls
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 (expressed as a time interval. For example, you can choose
to remain approximately 2 seconds behind the vehicle ahead).
