Cruise Control

Any given speed above a range of
approximately 16-40 k m /h /
10-25 mph, depending on model,
can be maintained with the cruise
control by operating the switch.
1 = S e ttin g (touch switch)
Accelerating (hold switch)
2 = Setting (touch switch)
Decelerating (hold switch)
Normally the vehicle is accele­
rated to the desired speed with
the accelerator. Speed is set by
briefly pushing the switch to
position " 1" or " 2" , and the
accelerator can be released.
The speed can be increased
(e. g. for passing) by using the
accelerator. As soon as the
accelerator is released, the
previously set speed w ill be
resumed autom atically.
If the set speed is to be in­
creased or decreased slightly
(e. g. fo r adaptation to the flow
of traffic), hold switch in
position " 1" or " 2" until the
desired speed is reached. When
the switch is released, the newly
set speed remains constant.
3 = Cancelling
To cancel the cruise control,
briefly push lever to position
''3".
The cruise control w ill also be
cancelled if the brake pedal is
actuated or if the vehicle speed
drops on steep grades by more
than 20 % below the set speed.
4 = R esum e
If the lever is briefly pushed to
position " 4 " when driving at a
speed exceeding approxim ately
16-40 k m /h /1 0 -2 5 mph,
depending on model, that speed
is resumed which was set prior
to the cancellation of the cruise
control.
The last memorized speed is
cancelled when the key in the
steering lock is turned to
position " 1" or " 0" .
Im portant:
Please do not use the cruise
control if traffic conditions do not
make it advisable to maintain a
steady speed, i. e. in heavy traffic
or on tw isting or slick and muddy
roads.
Position " Resume" should be
engaged only if the driver is fully
aware of the previously set speed
and wishes to resume this parti­
cular preset speed.
When driving with the cruise
control, the selector lever must
not be shifted to position "N "
as otherwise the engine will
overrev.
