Cruise control system
Introduction to the topic
The cruise control system helps to maintain
a speed set by the driver.
Speed range
The CCS is available when driving forwards at speeds
from around 20 km/h (15 mph).
Driving with the cruise control system
You can exceed the stored speed at any time, e.g. to
overtake. Control is interrupted for the duration of
the acceleration manoeuvre and is then resumed
with the stored speed.
Displays
When the CCS is switched on, the instrument cluster
display shows the stored speed and the status of the
CCS.
Depending on the situation and the instrument clus-
ter version, the following warning lamps light up:
CCS switched on.
CCS switched on, system control ac-
tive.
The indicator lamps are displayed small or grey
when the CCS is not active.
If no speed is stored, the instrument cluster display
shows
instead of the speed.
Changing gear
Cruise control is interrupted as soon as you depress
the clutch pedal and is resumed automatically after
the gear change.
Driving downhill
Driving downhill may cause the set speed to be ex-
ceeded.
Apply the foot brake to slow the vehicle down, and
change down a gear as required.
WARNING
The use of the CCS can lead to accidents and seri-
ous injuries if traffic does not allow you to drive at
a safe distance from the vehicle in front at a con-
stant speed.

x
Never use the CCS in heavy traffic, if the dis-
tance to the vehicles in front is insufficient, on
steep or winding roads, on slippery road surfa-
ces, e.g. due to snow, ice, wet roads, loose chip-
pings, or on flooded roads.
x
Never use the CCS when driving offroad or on
unpaved road surfaces.
x
Adapt your speed and distance from the vehi-
cles ahead to suit visibility, weather, road and
traffic conditions.
x
Always switch CCS off after use to avoid unin-
tentional speed control.
x
It is dangerous to use a set speed that is too
high for the prevailing road, traffic or weather
conditions.
