04 Comfort and driving pleasure
Adaptive cruise control*
tive is the set speed. This is also the case if the
speed of the vehicle ahead exceeds the cruise
control set speed.
The adaptive cruise control aims to control the
speed in a smooth way. In situations that
demand sudden braking you must brake your-
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 158.
04
Adaptive cruise control can only be activated
above 30 km/h. If speed falls below 30 km/h or
if engine speed becomes too slow, then the
adaptive cruise control disengages and stops
braking. In which case the driver must imme-
diately take over and maintain the distance to
vehicles in front. The highest speed setting is
200 km/h.
Warning lamp, braking by driver required
Adaptive cruise control has a braking capacity
that is equivalent to approximately 30% of the
car's braking capacity.
If the car needs to brake 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 to alert the driver that immediate inter-
vention 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.

The car symbol is illuminated
on the left-hand side of the
display when the radar sensor
has detected another vehicle.
The distance to vehicles in
front is only regulated when
the symbol is illuminated.
NOTE
Cruise control cannot be engaged at
speeds below 30 km/h.
