It consists of a cruise control system and a coor-
dinated spacing system.

Radar sensor (p. 219)
WARNING
Adaptive cruise control is not a collision avoid-
ance system. The driver must intervene if the
system does not detect a vehicle in front.
The adaptive cruise control does not brake for
humans or animals, and not for small vehicles
such as bicycles and motorcycles. Nor for low
trailers, oncoming, slow or stationary vehicles
and objects.
Do not use the adaptive cruise control, for
example, in city traffic, in dense traffic, at junc-
tions, 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.
Distance to the vehicle ahead (p. 211) is meas-
ured primarily by a radar sensor (p. 219). The
cruise control function regulates the speed with
acceleration and braking. It is normal for the
brakes to emit a low sound when they are being
used by the adaptive cruise control.
WARNING
The brake pedal moves when the adaptive
cruise control brakes. Do not rest your foot
beneath the brake pedal - it may then
become trapped.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane according to what
the driver set for time interval (p. 211). If the
radar sensor cannot see any vehicle in front then
the car will instead maintain the speed set and
stored by the driver. This also takes place if the
speed of the vehicle in front exceeds the stored
speed.
The adaptive cruise control aims to control the
speed in a smooth way. In situations that demand
sudden braking the driver must brake himself/
herself. This applies with large differences in
speed, or if the vehicle in front brakes heavily.
Due to limitations in the radar sensor (p. 219)
braking may come unexpectedly or not at all.
The adaptive cruise control can be activated to
follow another vehicle at speeds from 30 km/h
6
(20 mph) up to 200 km/h (125 mph). If the
speed falls below 30 km/h (20 mph) or if the
engine speed becomes too low, the cruise con-
trol is set in standby mode (p. 211) at which
automatic braking ceases - the driver must then
take over himself/herself to maintain a safe dis-
tance to the vehicle in front.

Queue Assist (p. 213) (in cars with automatic gearbox) can operate in the range 0-200 km/h (0-125 mph).
