Adaptive cruise control*

* Option/accessory, for more information, see Introduction.
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.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcycles.
Nor for oncoming, slow or stationary vehi-
cles 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.
The distance to the vehicle ahead is mainly
measured by a radar sensor. 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 cruise con-
trol.
WARNING
The brake pedal moves when the cruise
control brakes. Do not rest your foot under
the brake pedal as it could become trapped.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time interval
set by the driver. If the radar sensor cannot 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 cruise control aims to control the speed in
a smooth way. In situations that demand sud-
den braking the driver must brake himself/her-
self. This applies with large differences in
speed, or if the vehicle in front brakes heavily.
Due to limitations in the radar sensor, braking
may come unexpectedly or not at all, see
page 180.
The adaptive cruise control can be activated to
follow another vehicle at speeds from
30 km/h
3
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 at which automatic braking ceases - the
driver must then take over himself/herself to
maintain a safe distance to the vehicle ahead.
Warning lamp - braking by driver
required
Adaptive cruise control has a braking capacity
that is equivalent to more than 40% of the car's
braking capacity.
If the car needs to be braked more heavily than
cruise control capacity and the driver does not
brake, then the cruise control uses the collision
warning system's warning lamp and warning
sound (see page 193) to alert the driver that
immediate intervention is required.
NOTE
The warning lamp may be difficult to notice
in strong sunlight or when sunglasses are
being worn.
WARNING
Cruise control only warns of vehicles
detected by the radar sensor. Consequently
there may be no warning or it may be sub-
ject to a delay. Do not wait for a warning but
brake when it is necessary.
Steep roads and/or heavy load
Bear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The cruise control may have dif-
ficultly in keeping the correct distance from the
vehicle ahead when driving on steep roads,
with a heavy load or with a trailer - in which
case, be extra attentive and ready to slow
down.

Queue Assistant (in cars with automatic gearbox) can operate in the range of 0-200 km/h, see page 179.
