04

General

Adaptive Cruise Control (ACC) is designed to

assist the driver with support on long straight

roads in steady traffic, for example on motor-

ways and main roads.

Maintenance of cruise control components

must only be performed by an authorised

Volvo workshop

.

Controls

Radar sensor

Adaptive cruise control consists of the cruise

control system and coordinated spacing

system.

The distance to the vehicle ahead is meas-

ured by a radar sensor. The speed is regu-

lated by acceleration and braking. It is normal

for the brakes to emit a low sound when they

are being used by cruise control.

The cruise control objective is to follow the

vehicle ahead but in the same lane and at a

set distance. If the radar sensor has not

detected a vehicle ahead then the only

objective is the set speed. This is also the

WARNING

Adaptive cruise control cannot cover all

driving situations and traffic, weather and

road conditions.

The Function section on page 132 and after

informs about limitations that the driver

must be aware of before using the adaptive

cruise control.

When driving you are responsible for main-

taining the correct distance and speed,

even when adaptive cruise control is used.

You must always pay attention to the traffic

conditions and intervene when adaptive

cruise control is not maintaining a suitable

speed or suitable distance.

WARNING

Adaptive cruise control is not a collision

avoidance system. The driver must inter-

vene if the system does not detect a vehicle

in front.

Adaptive cruise control does not brake for

slow or stationary vehicles.

Do not use the adaptive cruise control, for

example, in city traffic, in dense traffic, at

junctions, on slippery surfaces, with a lot of

water or slush on the road, in heavy rain/

snow, in poor visibility, on winding roads or

on slip roads.

WARNING

The brake pedal moves when the cruise

control brakes. Do not rest your foot under

the brake pedal as it could become

trapped.
