WARNING
For safety reasons, do not use the ACC under the following conditions.
When driving in turning lanes, motorway exits or construction sites, to
■
avoid an unwanted acceleration to the stored speed.
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
Driving in "sharp" corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
■
ings, railway tracks, etc.) can be found.
When driving through very divided and enclosed spaces (such as large-ca-
■
pacity garages, car ferries, tunnels and the like.).
Note
The ACC is designed primarily for use on motorways.
■
The ACC reduces the speed by automatically releasing the accelerator or by
■
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.
In case of failure of more than one brake light on the vehicle or on the con-
■
nected trailer, the ACC becomes unavailable.
The control automatically cancels the engagement of the brake supportive
■
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

Read and observe
on page 148 first.
The ACC allows you to set a speed of 30 - 160 or 210 km / h (depending on
equipment) and the distance to the vehicle ahead in the range of a very short
to a very long distance.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
The ACC can detect a vehicle that is up to approx. 150 m ahead using the radar
sensor.

Regulation is inactive (in the colour display the digits of speed limits is
shown in grey).
Regulation active - no vehicle detected (in the colour display the digits of
the speed limits are highlighted).
Regulation deactivated - no speed stored.
