Warning lamp - braking by driver required
Steering wheel keypad (p. 202)
Radar sensor (p. 209)
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 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
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. 204) is
measured primarily by a radar sensor
(p. 209). 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. 204). 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. 209) 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

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. 205) at which automatic
braking ceases - the driver must then take
over himself/herself to maintain a safe dis-
tance to the vehicle ahead.

Queue Assist (p. 206) (in cars with automatic gearbox) can operate in the range 0-200 km/h.
