1 To maintain and store speed/
to accelerate
2 To decelerate
3 To recall the stored setting
4 To deactivate the system
Do not use cruise control on twisting
roads, when high traffic density pre-
vents driving at a constant speed, when the
road surface is slick, e.g. from snow, rain or
ice, nor when the road surface is loose, e.g.
from rocks or sand.<
To maintain and store speed/
to accelerate
You can maintain and store any desired
speed above approx. 20 mph / 30 km/h.
Press the lever briefly in direction 1:
The system maintains and stores the cur-
rent vehicle speed. Every time you tap the
lever, the speed increases by approx.
0.6 mph / 1 km/h.
Hold the lever in position 1:
The vehicle accelerates without pressure
on the accelerator pedal. As soon as you
release the lever, the system stores and
maintains the current speed.
If, on a downhill grade, the engine
braking effect is not sufficient, the
controlled speed can be exceeded. Speed
can drop on uphill grades if the engine out-
put is insufficient.<
