Adaptive cruise control* - function

The adaptive cruise control (ACC – Adaptive
Cruise Control) helps the driver to maintain an
even speed and a safe distance from the vehi-
cle ahead. It consists of a cruise control sys-
tem and a coordinated spacing system.

WARNING
Adaptive cruise control is not a collision
avoidance system. The driver must inter-
vene if the system does not detect a vehi-
cle in front.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcy-
cles. Nor for oncoming, slow or stationary
vehicles and objects.
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.
Distance to the vehicle ahead (p. 187) is
measured primarily by a radar sensor (p.
192). Cruise control 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 Cruise Con-
trol brakes. Do not rest your foot beneath
the brake pedal as it may become trapped.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time inter-
val set by the driver. If the radar sensor can-
not see any vehicle in front then the car will
instead maintain the cruise control's set
speed. This also happens if the speed of the
vehicle in front exceeds the cruise control's
set 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. 192) braking may come unexpect-
edly or not at all.
The adaptive cruise control can be activated
to follow another vehicle at speeds from
30 km/h 7 up to 200 km/h. If the speed falls
below 30 km/h or if the engine speed
becomes too low, the cruise control is set in
standby mode (p. 188) at which automatic
braking ceases - the driver must then take
over himself/herself to maintain a safe dis-
tance to the vehicle ahead.

required
Adaptive cruise control has a braking
capacity that is equivalent to more than 40%
of the car's braking capacity.
